While not flawless—sometimes misinterpreting legal terms or omitting information, thus not replacing lawyers—they offer a scalable solution for daily transactions. Arbel concludes these tools mark a significant improvement, potentially revolutionizing consumer contracting and necessitating a paradigm shift in law and policy, despite needing to address accuracy and bias concerns. 2. ## Section Summaries ≤120 words each (author phrase repeated) * Professor Yonathan Arbel of the University of Alabama School of Law writes that large language models (LLMs) as 'smart readers' can markedly reduce contract length and reading time, improving readability to a fifth-grade level without significant loss of essential information. However, he cautions that these tools are not flawless, sometimes miscommunicating legal terms or presenting errors. Thus, while they cannot replace lawyers, smart readers are effective for many daily transactions and signal a crucial need for a paradigm change in how contracts are approached. * Professor Yonathan Arbel of the University of Alabama School of Law writes that his paper investigates the capability of Large Language Models (LLMs) to address the pervasive "no-reading problem" by simplifying complex contractual texts. The study assesses the effectiveness of this simplification through metrics such as text length, complexity, and readability, and also critically evaluates the quality of these simplifications by analyzing specific clauses from major companies like the Wall Street Journal, Airbnb, and Amazon. * Professor Yonathan Arbel of the University of Alabama School of Law writes that a central challenge in consumer contracts is the "no-reading problem," where consumers' failure to engage with standard forms undermines informed decision-making and reduces sellers' incentives for fair terms. He explains that this chapter evaluates whether "smart readers," technological tools employing large language models, can effectively address this issue by simplifying contractual texts, thereby testing if current models have already achieved a utility threshold sufficient to empower consumers. * Professor Yonathan Arbel of the University of Alabama School of Law writes that his study examines how "smart readers" utilizing LLMs perform in simplifying legal documents by comparing complexity, length, readability, and quality before and after simplification, analyzing both entire agreements and specific clauses to tackle the "no-reading problem." He notes that while these smart readers significantly improve text difficulty and length and generally capture important aspects, they can struggle with certain clauses—sometimes understating, omitting, or providing incorrect information. Thus, they do not replace lawyers but offer a scalable solution for consumers. * Professor Yonathan Arbel of the University of Alabama School of Law writes that consumers often avoid reading form contracts because they are cognitively taxing and visually difficult, a situation that allows firms to implement a "HIDE" strategy using terms that are "Hardly Interpretable but Dependably Enforceable." He notes that in response, courts have sometimes imposed a "duty to read," while lawmakers have instituted numerous plain language laws aiming to improve contract readability and accessibility, though these traditional measures face challenges. * Professor Yonathan Arbel of the University of Alabama School of Law writes that current efforts to simplify legal contracts for consumers, such as plain language requirements, often prove inadequate. He argues these methods overlook consumer diversity, the challenges of low literacy, and the persistent issue of excessive contract length. However, the emergence of transformer AI technology, like GPT models, presents a promising new path with 'smart readers' capable of processing and interacting with complex legal texts in previously inconceivable ways, offering a potential solution. * Professor Yonathan Arbel of the University of Alabama School of Law writes that advanced large language models, or "smart readers," offer significant potential to empower consumers by personalizing and clarifying complex legal texts like contracts, thereby challenging sellers' obscure "HIDE" strategies. He acknowledges that while the technology in 2021 was nascent, unreliable, and met with skepticism, these issues were considered temporary, stemming from data and compute limitations rather than fundamental flaws, with subsequent models demonstrating clear advancements in capability and reliability. * Professor Yonathan Arbel of the University of Alabama School of Law writes that Large Language Models like GPT-4 have demonstrated remarkable capabilities by excelling in complex exams, which has shifted the public's focus from what the technology can do to exploring its limitations, thereby highlighting its significant potential. Given the rapid mass adoption and accessibility of this impressive technology, he asserts it is now timely to assess whether "smart readers" can effectively empower consumers and comprehensively address the widespread "no-reading problem" concerning contracts and policies. * Professor Yonathan Arbel of the University of Alabama School of Law writes that their examination of consumer contracts, including those from major companies like Netflix and Google, focuses on readability using tests such as Flesch Ease of Reading to explore if language models can make these documents more comprehensible. He also points out that these traditional readability tests, which primarily assess syntactic features like sentence length and word rarity, are critiqued for their limited reliability, validity, and high manipulability, suggesting a need for more nuanced evaluation methods. * Professor Yonathan Arbel of the University of Alabama School of Law writes that their research assesses language models' ability to simplify legal texts based on key criteria: improvements in readability, significant length reduction, and the crucial preservation of essential meaning and context. He explains that to address technical challenges, such as model selection and input length limits, they opted for cost-effective yet competent models like Claude and ChatGPT and also developed their own smart reader to manage these operational constraints effectively. * Professor Yonathan Arbel of the University of Alabama School of Law writes that a critical challenge in their research was devising a specific, iteratively developed prompt for AI models to simplify contracts effectively. This prompt aimed for no information loss, simpler language, and brevity while meticulously preserving necessary legal concepts. Their analysis then proceeded to test the AI's simplification ability using objective metrics like length and readability, and to assess the quality of summaries by their capacity to capture key contractual information accurately. * Professor Yonathan Arbel of the University of Alabama School of Law writes that their high-level results indicate that various AI models, on average, successfully reduced the word count of contracts to approximately 30% of their original length. He highlights that this substantial reduction in text significantly decreased the estimated reading time for these documents, for example, from an average of 20 minutes and 45 seconds for an original contract down to just 6 minutes and 6 seconds for its AI-simplified version. * Professor Yonathan Arbel of the University of Alabama School of Law writes that AI models demonstrate significant variability in summarization, producing outputs with widely different lengths and reduction percentages even when given similar prompts, indicating a large degree of inconsistency between them. He notes that beyond aggregated reductions in word count, sentence count, and reading time, another important way to assess the simplification of text is by examining its complexity, for instance, through a systematic count of difficult words within the processed text. * Professor Yonathan Arbel of the University of Alabama School of Law writes that by using the Dalle-Chall word list, his research found an average 61% reduction in difficult words when comparing original contractual texts to versions processed by various AI models. He further states that beyond merely counting difficult words, the study also comprehensively assessed overall text readability using established measures such as the Flesch-Kincaid score and an average derived from multiple readability assessment tools to provide a broader view of simplification. * Professor Yonathan Arbel of the University of Alabama School of Law writes that original contracts, typically requiring 10 to 14 years of schooling according to the Flesch-Kincaid measure, saw an average reduction in reading difficulty of 1.47 grade levels when processed by LLMs. He highlights that the best performing model, Claude-001, significantly improved readability, reducing the Flesch-Kincaid level by 5.6 grades to a 5.4 grade level. This makes contracts accessible to 11-year-olds and aligns with expert recommendations for consumer documents. * Professor Yonathan Arbel of the University of Alabama School of Law writes that despite prompts to simplify contracts, some large language models surprisingly made them more complex, although models like Claude-001 and Text-Davinci-003 showed more consistent success in this task. He adds that his team also subjectively assessed output quality by comparing Spotify's original terms with simplified versions from ChatGPT-Turbo and Claude, specifically looking for whether 11 identified "traps" for unwary consumers were adequately addressed in the simplified outputs. * Professor Yonathan Arbel of the University of Alabama School of Law writes that while both smart reader platforms effectively simplified contracts and captured most important information and identified "traps," they exhibited varied success and omissions. This suggests models could be complementary and that LLMs might systematically miss certain types of information. He notes that current flaws, such as those arising from "chunking" text, are considered transient, and the research subsequently shifted to analyzing specific challenging clauses to develop a more robust understanding of simplification quality. * Professor Yonathan Arbel of the University of Alabama School of Law writes that the research actively selected consumer-relevant contract clauses, such as those concerning unilateral modifications by companies, and utilized GPT-4 to create simplified versions. These simplified versions were then meticulously evaluated for improvements in length, complexity, and the overall quality of simplification. An analysis of a Wall Street Journal clause allowing unilateral changes to its subscriber agreement found GPT-4's simplification to be highly effective in clarifying this term of considerable importance to consumers. * Professor Yonathan Arbel of the University of Alabama School of Law writes that while a simplified contract version is generally true to the original and clearly presents its main point, it may subtly mislead consumers. For instance, it might imply changes are entirely unilateral, contrasting with the original's requirement that changes are only effective if communicated. Despite this, he notes this simplified version demonstrates significant quantitative improvements, reducing text complexity by nearly 7.5 to 8 grade levels to an eighth-grade reading standard, cutting word count by 26%, and decreasing average word length. * Professor Yonathan Arbel of the University of Alabama School of Law writes that the Wall Street Journal's original 'Agreement to Arbitrate' clause stipulates that most controversies or claims, with specific exceptions for intellectual property and small claims court disputes, will be resolved by arbitration administered by the American Arbitration Association. He further clarifies that by entering into this agreement, individuals effectively waive their right to a jury trial and are explicitly barred from participating in class arbitrations or class actions. * Professor Yonathan Arbel of the University of Alabama School of Law writes to present example arbitration clauses, both in standard legal language and a simplified version. These clauses stipulate that most disputes will be resolved through arbitration governed by New York law and the Federal Arbitration Act, thereby waiving jury trials and prohibiting class actions. He further details these clauses, which specify arbitration locations, procedural options for small claims under $14,000, and limitations on the arbitrator's award to individual relief, typically without a statement of reasons unless jointly requested. * Professor Yonathan Arbel of the University of Alabama School of Law writes that while simplifying a mandatory arbitration clause is generally beneficial, the evaluated attempt introduced problems. These included reducing the salience of arbitration, altering the legal meaning of terms like 'intellectual property' and 'equitable relief,' and critically omitting the customer's right to bring complaints to state or federal agencies. Despite these shortcomings, he notes the simplification dramatically reduced reading complexity from a PhD to an eighth-grade level, though effectively translating complex legal terms like 'equitable relief' into simple language remains a pressing dilemma. * Professor Yonathan Arbel of the University of Alabama School of Law writes that analysis of publications like the Wall Street Journal indicates a trend towards clause simplification and shorter average word lengths in their contractual terms. He also notes that companies like Airbnb outline in their policies how they collect personal information from third-party services, such as linked social media accounts, and also obtain background information or criminal records as permitted by applicable laws, illustrating common data collection practices. * Professor Yonathan Arbel of the University of Alabama School of Law writes that Airbnb details its collection of personal information from various third-party sources, including co-travelers, insurance claims, connected services like Google, and background check providers, and presents a simplified version of this policy section. He observes that this simplification successfully distills the original provision’s complex legal language into more accessible terms for consumers without distorting the overall meaning regarding third-party data collection practices by the company. * Professor Yonathan Arbel of the University of Alabama School of Law writes that while Airbnb's simplified privacy policy offers some clearer phrasing, it problematically omits important details such as the sharing of friend lists. He also notes it can be misleading regarding user consent for background checks and the extent of information sharing with insurers. However, quantitatively, the simplified policy shows substantial improvement, reducing readability from a college level to a sixth or seventh grade level and decreasing the word count by a significant 50%. * Professor Yonathan Arbel of the University of Alabama School of Law writes that while the simplified Netflix cancellation clause generally maintains the original's integrity and improves accessibility, cancellation provisions are inherently tricky in consumer contracts. He points out that this specific simplification, however, contains a critical misinterpretation of the refund policy by omitting the original's qualification that payments are non-refundable only "to the extent permitted by the applicable law," which could consequently mislead consumers about their rights in certain jurisdictions. * Professor Yonathan Arbel of the University of Alabama School of Law writes that Netflix's simplified text erroneously claims an inability to refund payments, a statement that could potentially mislead consumers in jurisdictions where laws may mandate such refunds under certain circumstances. He notes that despite this significant miscommunication regarding refund policies, the simplification still managed to improve readability to a 6th-7th grade level, although with only a modest 16% reduction in word count compared to the original clause. * Professor Yonathan Arbel of the University of Alabama School of Law writes that Amazon's terms permit users to post content like reviews and comments, provided it is not illegal, obscene, or infringing. Amazon reserves the right, but not the obligation, to remove or edit such content without regular review. He further explains that by posting content, users grant Amazon a nonexclusive, royalty-free, perpetual, irrevocable, and fully sublicensable right to use, reproduce, and distribute that content worldwide, and users also warrant ownership and agree to indemnify Amazon for claims arising from their content. * Professor Yonathan Arbel of the University of Alabama School of Law writes that while the evaluated simplification of a contract provision governing user content contribution, like online reviews on Amazon, is largely effective and impressively improves readability, it does omit some important restrictions present in the original text. He highlights a more significant concern: that the simplification, despite communicating most user obligations, might not sufficiently convey the gravity of these potentially burdensome warranties (such as ensuring review accuracy and non-harm) due to its less formal tone. * Professor Yonathan Arbel of the University of Alabama School of Law writes that dense legal clauses, such as Amazon's "Risk of Loss" terms, can be significantly simplified by using shorter sentences and more straightforward language, as demonstrated by a tangible reduction in average word length in the simplified versions. He illustrates that this simplification effectively transforms complex statements, like Amazon's original risk of loss clause, into much clearer terms such as "When you buy physical items from Amazon, they are yours once we give them to the carrier for delivery." * Professor Yonathan Arbel of the University of Alabama School of Law writes that while a simplified contract clause regarding delivery risk effectively communicates ownership transfer to the buyer upon shipping, it inadequately conveys that the customer bears the risk if delivery subsequently fails. He notes that this criticism of unclear risk allocation extends to simplified return clauses as well, and observes that while the simplification achieved only modest readability gains for an already relatively simple original clause, more significant improvements could potentially be made. * Professor Yonathan Arbel of the University of Alabama School of Law writes that Yahoo's privacy policy details how user information is shared within its affiliated brands and companies, and also for purposes described in its policy, including the provision of requested services to users. He further notes that Yahoo asserts it does not sell, license, or share information that individually identifies customers with external companies unless specific circumstances apply, such as obtaining user consent, sharing within Yahoo affiliates, or with trusted partners under confidentiality measures. * Professor Yonathan Arbel of the University of Alabama School of Law writes that Yahoo shares aggregated or pseudonymous, non-personally identifiable user information with partners like advertisers and analytics companies, while also sharing information within its own related brands and companies. He clarifies that personally identifiable information is not shared with outside companies unless users give explicit permission, and notes that third-party apps, websites, or advertisers integrated with Yahoo services collect data under their own distinct privacy policies, separate from Yahoo's. * Professor Yonathan Arbel of the University of Alabama School of Law writes that while AI simplification can capture the intended logic of complex legal provisions, such as Yahoo's policies on information sharing, its value is inherently limited if the original legal documents are poorly drafted or contain logical inconsistencies. Despite these limitations, he finds that AI simplification proved helpful by dramatically reducing text complexity and improving readability, though he cautions that firms might adopt specific drafting strategies to circumvent the effectiveness of smart readers. * Professor Yonathan Arbel of the University of Alabama School of Law writes that Spotify's terms state a user's sole remedy for dissatisfaction with its service or any linked third-party applications is to uninstall the service and cease using them. He further explains that Spotify also disclaims liability for various types of damages, capping its aggregate liability for all claims related to the service at the greater of the amounts paid by the user in the prior twelve months or a nominal sum of $30.00. * Professor Yonathan Arbel of the University of Alabama School of Law writes that Spotify's terms attempt to significantly limit its liability, for instance by stating the user's sole remedy for issues is to stop using the service and by capping potential monetary damages at recent payments or $30. He observes that these liability limitation clauses, while common in consumer contracts, are worded inconsistently and confusingly within Spotify's terms, initially offering uninstallation as the only remedy before then moving to limit monetary damages. * Professor Yonathan Arbel of the University of Alabama School of Law writes that while a simplification of Spotify's disclaimer had some communicative benefits for consumers, it problematically altered the legal meaning of the clause. This was achieved by replacing specific legal terms with simpler but inexact phrases. Quantitatively, he notes this simplification improved readability scores but also slightly increased document length and, importantly, highlighted the limitations of standard readability tests when dealing with complex sentence structures common in legal texts. * Professor Yonathan Arbel of the University of Alabama School of Law writes that simplified legal clauses demonstrated enhanced accessibility through notably shorter length, reduced complexity, and significantly improved readability metrics, on average halving the required education level for comprehension. However, he cautions that despite these substantial gains, simplified texts might still be inaccessible by standard metrics and offer no guarantee that consumers will actually read them, though an overall significant improvement in understandability was observed across the board. * Professor Yonathan Arbel of the University of Alabama School of Law writes that while smart readers made contracts more accessible with simpler language, their accuracy was mixed; some simplifications were beneficial, but others introduced substantial issues such as suggesting non-existent active consent requirements or omitting crucial consumer rights. A significant observed problem was the incorrect usage of legal terminology, like confusing "consequential" with "follow-on" damages, which could be harmful if courts adopt the smart reader's potentially flawed interpretation over the canonical contract. * Professor Yonathan Arbel of the University of Alabama School of Law writes that smart readers can substantially shorten legal texts, reduce their complexity, and improve overall readability, generally including important information in their summaries. He concludes that while not perfect, these simplification tools offer a marked improvement over the common scenario of consumers not reading legal texts at all, potentially facilitating more informed decisions and thereby enhancing market efficiency by better aligning consumer understanding with contractual obligations. * Professor Yonathan Arbel of the University of Alabama School of Law writes that current smart reader models, though not yet replacements for lawyers, have effectively arrived and can serve as a cheap, effective, and scalable alternative for the many contracts and privacy policies that presently go unread by consumers. He states that despite their revolutionary potential to transform consumer contracting, concerns regarding accuracy, corporate capture, and bias must be diligently addressed, as their materializing potential would make a law and policy paradigm shift appropriate, if not inevitable.)MW4LLM"; static const std::string SUMMARY_ZH_MD = R"MW4LLM(好的,这是您提供的英文法律摘要的正式中文翻译: 1. ## 内容摘要 ≤100字 (以“阿拉巴马大学法学院的Yonathan Arbel教授认为”开头) 阿拉巴马大学法学院的Yonathan Arbel教授认为,作为“智能阅读器”的大型语言模型(LLMs)能显著简化复杂合同,缩短篇幅、提高可读性,以赋能消费者对抗“不阅读问题”。虽非完美——偶有误解法律术语或遗漏信息,故无法取代律师——但它们为日常交易提供了可扩展方案。Arbel教授总结,这些工具是重大进步,有望革新消费者签约,并促使法律政策范式转变,惟需解决准确性与偏见问题。 2. ## 各章节摘要 ≤120字/每条 (重复作者引语) * 阿拉巴马大学法学院的Yonathan Arbel教授指出,作为“智能阅读器”的大型语言模型(LLMs)能显著缩短合同篇幅和阅读时间,将可读性提升至五年级水平,且基本不损失重要信息。但他提醒,这些工具并非完美,有时会错误传达法律术语或出现错误。因此,智能阅读器虽不能取代律师,但对许多日常交易有效,并表明亟需对合同处理方式进行范式变革。 * 阿拉巴马大学法学院的Yonathan Arbel教授指出,其论文研究了大型语言模型(LLMs)通过简化复杂合同文本以解决普遍存在的“不阅读问题”的能力。该研究通过文本长度、复杂性和可读性等指标评估简化效果,并通过分析《华尔街日报》、爱彼迎和亚马逊等大公司的具体条款,严格评估了这些简化的质量。 * 阿拉巴马大学法学院的Yonathan Arbel教授指出,消费者合同的核心挑战在于“不阅读问题”,即消费者未能理解标准格式合同,这削弱了知情决策,并降低了卖方提供公平条款的动机。他解释道,本章评估了采用大型语言模型的“智能阅读器”这类技术工具能否通过简化合同文本有效解决此问题,从而检验当前模型是否已达到足以赋能消费者的效用阈值。 * 阿拉巴马大学法学院的Yonathan Arbel教授指出,其研究通过比较简化前后的复杂度、长度、可读性和质量,分析了整个协议和特定条款,以考察“智能阅读器”(利用LLMs)在简化法律文件方面的表现,旨在解决“不阅读问题”。他提到,尽管这些智能阅读器显著改善了文本难度和长度,并通常能抓住要点,但在处理某些条款时可能存在不足——有时会轻描淡写、遗漏或提供错误信息。因此,它们不能取代律师,但为消费者提供了可扩展的解决方案。 * 阿拉巴马大学法学院的Yonathan Arbel教授指出,消费者常因格式合同认知负荷大且视觉上难以阅读而避免阅读,这种情况使得公司得以实施“HIDE”策略,使用“难以理解但可强制执行”的条款。他提到,作为回应,法院有时会施加“阅读义务”,而立法者则制定了许多旨在提高合同可读性和易获取性的通俗语言法,尽管这些传统措施面临挑战。 * 阿拉巴马大学法学院的Yonathan Arbel教授指出,当前为消费者简化法律合同的努力,如通俗语言要求,往往不尽如人意。他认为这些方法忽视了消费者的多样性、低读写能力的挑战以及合同篇幅过长这一持续存在的问题。然而,以GPT模型为代表的Transformer人工智能技术的出现,带来了“智能阅读器”这一前景广阔的新路径,其能够以前所未有的方式处理复杂法律文本并与之互动,为解决问题提供了潜在方案。 * 阿拉巴马大学法学院的Yonathan Arbel教授指出,先进的大型语言模型,即“智能阅读器”,通过个性化和阐释如合同之类的复杂法律文本,在赋能消费者方面展现出巨大潜力,从而挑战了卖方晦涩的“HIDE”策略。他承认,尽管2021年时该技术尚不成熟、不可靠且受到质疑,但这些问题被认为是暂时的,源于数据和计算能力的限制而非根本缺陷,后续模型已在能力和可靠性方面展现出明显进步。 * 阿拉巴马大学法学院的Yonathan Arbel教授指出,诸如GPT-4之类的大型语言模型通过在复杂考试中表现出色,已展现出卓越能力,这使公众的关注点从技术能做什么转向探究其局限性,从而凸显了其巨大潜力。鉴于这项令人印象深刻的技术已迅速大规模普及且易于获取,他断言,现在是评估“智能阅读器”能否有效赋能消费者并全面解决合同与政策方面普遍存在的“不阅读问题”的适当时机。 * 阿拉巴马大学法学院的Yonathan Arbel教授指出,他们对包括Netflix和谷歌等大公司在内的消费者合同的审查,侧重于使用弗莱什易读性等测试方法评估可读性,以探究语言模型能否使这些文件更易理解。他还指出,这些主要评估句子长度和词语罕见度等句法特征的传统可读性测试,因其可靠性、有效性有限且易被操控而受到批评,这表明需要更细致的评估方法。 * 阿拉巴马大学法学院的Yonathan Arbel教授指出,他们的研究基于关键标准评估语言模型简化法律文本的能力:可读性的改善、篇幅的显著缩减以及核心含义和语境的关键保留。他解释说,为应对模型选择和输入长度限制等技术挑战,他们选择了如Claude和ChatGPT这样性价比高且功能胜任的模型,并开发了自己的智能阅读器以有效管理这些操作限制。 * 阿拉巴马大学法学院的Yonathan Arbel教授指出,其研究中的一个关键挑战是为人工智能模型设计一个具体的、迭代开发的提示指令,以有效简化合同。该提示指令旨在实现信息无损、语言简化和简洁,同时审慎保留必要的法律概念。他们的分析随后使用长度和可读性等客观指标测试了人工智能的简化能力,并通过其准确捕捉关键合同信息的能力来评估摘要的质量。 * 阿拉巴马大学法学院的Yonathan Arbel教授指出,他们的高层次结果表明,各种人工智能模型平均成功地将合同字数减少至原文长度的约30%。他强调,文本的大幅缩减显著减少了这些文件的预计阅读时间,例如,一份原始合同的平均阅读时间从20分45秒降至人工智能简化版的仅6分6秒。 * 阿拉巴马大学法学院的Yonathan Arbel教授指出,人工智能模型在摘要生成方面表现出显著的变异性,即使给予相似的提示指令,其输出的长度和缩减百分比也大相径庭,表明模型间存在很大程度的不一致性。他提到,除了词数、句数和阅读时间的总体减少外,评估文本简化的另一个重要方法是考察其复杂性,例如,通过系统性统计处理后文本中的疑难词汇数量。 * 阿拉巴马大学法学院的Yonathan Arbel教授指出,通过使用Dalle-Chall词汇表,其研究发现,在比较原始合同文本与经各种人工智能模型处理后的版本时,疑难词汇平均减少了61%。他进一步指出,除了简单计算疑难词汇外,该研究还运用弗莱什-金凯德评分以及综合多种可读性评估工具得出的平均值等既定标准,全面评估了整体文本可读性,以提供更广泛的简化视角。 * 阿拉巴马大学法学院的Yonathan Arbel教授指出,根据弗莱什-金凯德标准,原始合同通常需要10至14年的学校教育才能理解,经大型语言模型处理后,阅读难度平均降低了1.47个年级水平。他强调,表现最佳的模型Claude-001显著提高了可读性,将弗莱什-金凯德等级降低了5.6个年级,达到了5.4年级水平。这使得合同对11岁儿童也易于理解,并符合专家对消费者文件的建议。 * 阿拉巴马大学法学院的Yonathan Arbel教授指出,尽管提示要求简化合同,但一些大型语言模型出人意料地使其更为复杂,不过Claude-001和Text-Davinci-003等模型在此任务中表现出更稳定和成功的简化效果。他补充说,其团队还通过比较Spotify的原始条款与ChatGPT-Turbo和Claude生成的简化版本,主观评估了输出质量,特别关注简化版是否充分处理了11个已识别的针对粗心消费者的“陷阱”。 * 阿拉巴马大学法学院的Yonathan Arbel教授指出,尽管两个智能阅读器平台均有效地简化了合同,并捕捉了大部分重要信息及识别出的“陷阱”,但它们在成功程度和遗漏方面表现各异。这表明不同模型可能具有互补性,且大型语言模型可能系统性地遗漏某些类型的信息。他指出,当前诸如文本分块处理引发的缺陷被认为是暂时性的,研究随后转向分析特定的疑难条款,以更深入地理解简化质量。 * 阿拉巴马大学法学院的Yonathan Arbel教授指出,该研究主动选取了与消费者相关的合同条款,例如涉及公司单方面修改权的条款,并利用GPT-4创建了简化版本。随后,对这些简化版本在长度、复杂性以及整体简化质量方面的改进进行了细致评估。对《华尔街日报》一项允许单方面更改其订户协议的条款分析发现,GPT-4的简化在阐明这一对消费者至关重要的条款方面非常有效。 * 阿拉巴马大学法学院的Yonathan Arbel教授指出,尽管简化后的合同版本通常忠于原文并清晰呈现其要点,但它可能巧妙地误导消费者。例如,它可能暗示变更完全是单方面的,而原文则要求变更需经通知方可生效。尽管如此,他指出这个简化版本在量化指标上展现了显著改进,将文本复杂度降低了近7.5至8个年级,达到八年级阅读水平,词数减少了26%,平均词长也有所缩短。 * 阿拉巴马大学法学院的Yonathan Arbel教授指出,《华尔街日报》的原始“仲裁协议”条款规定,除知识产权和小额索赔法庭争议等特定例外情况外,大多数争议或索赔将通过美国仲裁协会管理的仲裁解决。他进一步阐释,签订此协议即意味着个人有效放弃陪审团审判权,并明确禁止参与集体仲裁或集体诉讼。 * 阿拉巴马大学法学院的Yonathan Arbel教授指出,为展示仲裁条款示例,特提供标准法律文本和简化版本。这些条款规定,多数争议将通过受纽约州法律及《联邦仲裁法》管辖的仲裁解决,从而放弃陪审团审判并禁止集体诉讼。他进一步详述了这些条款,包括仲裁地点、14000美元以下小额索赔的程序选项,以及仲裁员裁决仅限于个体救济且通常不附理由说明(除非双方共同要求)的限制。 * 阿拉巴马大学法学院的Yonathan Arbel教授指出,尽管简化强制性仲裁条款通常有益,但所评估的尝试却引入了问题。这些问题包括降低了仲裁的显著性,改变了“知识产权”和“衡平法救济”等术语的法律含义,并严重遗漏了客户向州或联邦机构投诉的权利。尽管存在这些不足,他指出简化版将阅读复杂度从博士水平显著降低至八年级水平,但如何有效地将“衡平法救济”等复杂法律术语转化为简单语言仍是一个亟待解决的难题。 * 阿拉巴马大学法学院的Yonathan Arbel教授指出,对《华尔街日报》等出版物的分析表明,其合同条款有条款简化和平均词长缩短的趋势。他还提到,像爱彼迎这样的公司在其政策中概述了如何从第三方服务(如关联的社交媒体账户)收集个人信息,并在适用法律允许的情况下获取背景信息或犯罪记录,这说明了常见的数据收集做法。 * 阿拉巴马大学法学院的Yonathan Arbel教授指出,爱彼迎详述了其从各种第三方来源收集个人信息的情况,包括同行旅伴、保险索赔、关联服务(如谷歌)及背景调查提供商,并展示了该政策部分的简化版本。他观察到,此简化成功地将原始条款复杂的法律语言提炼为消费者更易理解的表述,且未扭曲公司关于第三方数据收集实践的整体含义。 * 阿拉巴马大学法学院的Yonathan Arbel教授指出,尽管爱彼迎简化后的隐私政策在措辞上更为清晰,但它在遗漏重要细节(如好友列表的共享)方面存在问题。他还指出,该简化版在用户对背景调查的同意以及与保险公司共享信息的范围方面可能产生误导。然而,从量化角度看,简化后的政策有显著改进,可读性从大学水平降至六或七年级水平,字数也大幅减少了50%。 * 阿拉巴马大学法学院的Yonathan Arbel教授指出,虽然Netflix简化后的取消条款通常保持了原文的完整性并提高了易获取性,但取消条款本身在消费者合同中就具有复杂性。他指出,此特定简化版本在退款政策的解读上存在关键性错误,遗漏了原文中“付款不可退还”仅限于“在适用法律允许的范围内”这一限定条件,这可能导致消费者对其在某些司法管辖区的权利产生误解。 * 阿拉巴马大学法学院的Yonathan Arbel教授指出,Netflix的简化文本错误地声称无法退款,这一陈述在某些法律可能规定特定情况下必须退款的司法管辖区内,可能会误导消费者。他指出,尽管在退款政策方面存在此等重大信息传递失误,该简化版仍成功地将可读性提高至六至七年级水平,尽管与原始条款相比,字数仅略微减少了16%。 * 阿拉巴马大学法学院的Yonathan Arbel教授指出,亚马逊的条款允许用户发布评论等内容,前提是内容不违法、不淫秽或不侵权。亚马逊保留移除或编辑此类内容的权利(而非义务),且不进行定期审查。他进一步解释,用户发布内容即授予亚马逊一项非排他性、免版税、永久、不可撤销且完全可再许可的权利,在全球范围内使用、复制和分发该内容;用户还需保证拥有所有权,并同意就其内容引发的索赔对亚马逊进行赔偿。 * 阿拉巴马大学法学院的Yonathan Arbel教授指出,尽管对一项规管用户内容贡献(如亚马逊在线评论)的合同条款的评估简化版大体有效,并显著提高了可读性,但它确实遗漏了原文中的一些重要限制。他强调了一个更值得关注的问题:该简化版尽管传达了大部分用户义务,但由于其语气不够正式,可能未能充分传达这些潜在繁琐保证义务(如确保评论准确性和无害性)的严肃性。 * 阿拉巴马大学法学院的Yonathan Arbel教授指出,诸如亚马逊“灭失风险”条款等密集的法律条文,可以通过使用更短的句子和更直白的语言得到显著简化,简化版本中平均词长的切实减少即证明了这一点。他举例说明,这种简化有效地将复杂陈述(如亚马逊原始的灭失风险条款)转化为更清晰的表述,例如“当您从亚马逊购买实物商品时,一旦我们将其交给承运人进行配送,商品即归您所有。” * 阿拉巴马大学法学院的Yonathan Arbel教授指出,尽管简化后的关于交付风险的合同条款有效地传达了所有权在发货时即转移给买方,但它未能充分说明若后续交付失败,客户仍需承担风险。他指出,这种对风险分配不明确的批评同样适用于简化后的退货条款,并观察到,虽然对于一个本已相对简单的原始条款,该简化仅实现了适度的可读性提升,但仍有潜力做出更显著的改进。 * 阿拉巴马大学法学院的Yonathan Arbel教授指出,雅虎的隐私政策详细说明了用户信息如何在其附属品牌和公司内部共享,以及用于其政策中所述的目的,包括向用户提供所请求的服务。他进一步指出,雅虎声明其不会向外部公司出售、许可或共享可单独识别客户身份的信息,除非特定情况适用,例如获得用户同意、在雅虎附属公司内部共享,或与保密措施下的可信合作伙伴共享。 * 阿拉巴马大学法学院的Yonathan Arbel教授指出,雅虎与其合作伙伴(如广告商和分析公司)共享汇总的或假名化的、非个人可识别的用户信息,同时也在其自有相关品牌和公司内部共享信息。他澄清,除非用户明确许可,否则个人可识别信息不会与外部公司共享,并指出与雅虎服务集成的第三方应用程序、网站或广告商根据其自身独立的隐私政策收集数据,这些政策与雅虎的政策不同。 * 阿拉巴马大学法学院的Yonathan Arbel教授指出,虽然人工智能简化能够捕捉复杂法律条款(如雅虎关于信息共享的政策)的预期逻辑,但如果原始法律文件起草不佳或包含逻辑矛盾,其价值则 inherently limited(本质上有限)。尽管存在这些局限性,他发现人工智能简化通过显著降低文本复杂性和提高可读性证明是有帮助的,但他同时警告,公司可能会采取特定的起草策略来规避智能阅读器的有效性。 * 阿拉巴马大学法学院的Yonathan Arbel教授指出,Spotify的条款声明,用户对其服务或任何关联第三方应用程序不满的唯一补救措施是卸载该服务并停止使用。他进一步解释,Spotify还不承担各种类型损害的责任,并将其与服务相关的所有索赔的总赔偿责任上限设定为用户在前十二个月支付的金额与象征性的30.00美元两者中的较大者。 * 阿拉巴马大学法学院的Yonathan Arbel教授指出,Spotify的条款试图显著限制其责任,例如声明用户对问题的唯一补救措施是停止使用服务,并将潜在的金钱赔偿上限设定为最近支付的金额或30美元。他观察到,这些责任限制条款虽然在消费者合同中常见,但在Spotify的条款中措辞不一致且令人困惑,最初将卸载作为唯一补救措施,随后又转而限制金钱赔偿。 * 阿拉巴马大学法学院的Yonathan Arbel教授指出,尽管Spotify免责声明的简化版本对消费者在信息沟通方面带来一些益处,但它通过将特定的法律术语替换为更简单但不精确的短语,从而在问题性地改变了条款的法律含义。从量化角度看,他指出这种简化提高了可读性分数,但也略微增加了文件长度,并且重要的是,凸显了标准可读性测试在处理法律文本中常见的复杂句子结构时的局限性。 * 阿拉巴马大学法学院的Yonathan Arbel教授指出,简化后的法律条款通过显著缩短的长度、降低的复杂性和大幅改善的可读性指标,展现了增强的可访问性,平均将理解所需的教育水平降低了一半。然而,他警告说,尽管取得了这些实质性进展,简化后的文本按标准指标衡量可能仍然难以访问,并且不能保证消费者会实际阅读它们,尽管在整体可理解性方面观察到了普遍的显著改善。 * 阿拉巴马大学法学院的Yonathan Arbel教授指出,尽管智能阅读器通过更简单的语言使合同更易获取,但其准确性参差不齐;一些简化是有益的,但另一些则引入了重大问题,例如暗示了不存在的主动同意要求或遗漏了关键的消费者权利。一个观察到的显著问题是法律术语使用不当,例如将“间接”损害(consequential damages)与“后续”损害(follow-on damages)混淆,如果法院采纳智能阅读器可能存在缺陷的解释而非规范合同文本,这可能是有害的。 * 阿拉巴马大学法学院的Yonathan Arbel教授指出,智能阅读器能够大幅缩短法律文本,降低其复杂性,并提高整体可读性,通常能在其摘要中包含重要信息。他总结道,虽然并非完美,但与消费者根本不阅读法律文本的普遍情况相比,这些简化工具提供了显著的改进,有可能促进更明智的决策,从而通过更好地使消费者理解与合同义务相一致来提高市场效率。 * 阿拉巴马大学法学院的Yonathan Arbel教授指出,当前的智能阅读器模型虽然尚不能取代律师,但已有效问世,并可作为一种廉价、有效且可扩展的替代方案,用于处理目前消费者普遍不阅读的众多合同和隐私政策。他表示,尽管它们具有革新消费者签约的革命性潜力,但必须努力解决有关准确性、企业俘获和偏见的问题,因为其潜力的实现将使得法律和政策范式的转变变得适当,甚至不可避免。)MW4LLM"; static const std::string

In this study, we investigate the extent to which state-of-the-art models can reliably operate as ‘smart readers’: applications that empower consumers to tackle lengthy, difficult-to-read, and inaccessible standard form contracts and privacy policies. Our analysis reveals that smart readers (1) reduce by 66.9% the length of contracts; (2) reduce reading time by 14:41 minutes (3) improve text readability by converting college-level texts to texts readable by fifth-grade students; and (4) do so without considerably compromising the essential information in the original contracts. Despite these impressive results, smart readers are not flawless. They sometimes miscommunicate legal terminology and occasionally present information in a misleading or erroneous manner. Such issues prevent smart readers from replacing the advice of a qualified lawyer. However, for the large mass of daily transactions where consumers would not consider using a lawyer, current-generation smart readers could be an effective tool. We thus conclude that current generation smart readers have arrived and that their arrival invites an academic and policy paradigm change.  Associate Professor of Law, University of Alabama, School of Law  Professor of Law and Associate Dean (Research), Victoria University of Wellington; Lee Kong Chian Visiting Professor of Law, Yong Pung How School of Law, Singapore Management University.

INTRODUCTION An organizing problem in consumer contracts is the no-reading problem.1 The common view in the scholarship is that consumers rarely read standard form contracts,2 and, therefore, their manifested assent to them is superficial.3 If consumers indeed do not read (let alone understand) the terms of their transactions, their ability to make informed decisions is doubtful, and sellers’ incentive to provide fair and efficient contract terms is undermined.4 This chapter evaluates whether smart readers—technological tools that use large language models (LLMs) to parse texts—can solve this problem and transform standard form contracting. We evaluate this question by testing current models on their ability to simplify contractual texts. Testing current generation models might seem like writing on ice: the rate of technological improvement is staggering, and whatever results we obtain today will be eclipsed by tomorrow’s models.5 Yet, we engage in this analysis because we want to determine if today’s smart readers have already managed to pass a utility threshold. If today’s smart readers can empower consumers, this would directly impact the large body of scholarship and policy directed at solving this problem 1 See generally Ian Ayres & Alan Schwartz, The No-Reading Problem in Consumer Contract Law, 66 STAN. L. REV. 545 (2014) (describing the no-reading problem and offering a solution to it); see also RESTATEMENT OF CONSUMER CONTS. § 3 Reporters’ Notes (AM. L. INST., Tentative Draft 2019) (pointing out that the terms of standard form contracts are “invisible to most consumers” and discussing how firms that modify their contracts must give consumers reasonable notice); Melvin Aron Eisenberg, Text Anxiety, 59 S. CAL. L. REV. 305 (1986) (theorizing that when consumers confront the dense text of form contracts, they respond by refusing to read it). 2 The exact scope of the problem is somewhat contested, but there is at least one domain definitely afflicted by extremely low levels of readership: online end-user license agreements. See, e.g., Yannis Bakos, Florencia Marotta-Wurgler & David R. Trossen, Does Anyone Read the Fine Print? Consumer Attention to Standard-Form Contracts, 43 J. LEGAL STUD. 1, 22 (2014) (finding that consumers rarely read the terms of end-user license agreements). 3 Victoria C. Plaut & Robert P. Bartlett, Blind Consent? A Social Psychological Investigation of Non- Readership of Click-Through Agreements, 36 L. & HUM. BEHAV. 293, 293 (2012) (noting the “documented phenomenon” of “‘blind consent’” — accepting the terms without reading them — associated with “standard, paper-based contracts” now occurs with online Click-Through Agreements). To be sure, the no- reading problem presents additional challenges, aside from consent, to consumer contracting, and consumers’ consent should be doubted for reasons other than the no-reading problem. See, e.g., Michael I. Meyerson, The Reunification of Contract Law: The Objective Theory of Consumer Form Contracts, 47 U. MIAMI L. REV. 1263 (1993) (discussing contractual issues in battle of the forms cases where seller includes a disclaimer of warranty of merchantability that the buyer does not read and highlighting the importance of informing consumers, even if they do not read or grasp the terms); Margaret Jane Radin, Boilerplate Today: The Rise of Modularity and The Waning of Consent, 104 MICH. L. REV. 1223 (2006) (discussing how even if companies make terms easier to read, consumers will not necessarily read them and asserting that consent is fictional, when, for instance, the terms are filed somewhere inaccessible, as in airline tariffs). Recent work argues that AI contracting technologies, namely “nano contracts,” will autonomously negotiate contracts and circumvent the standard negotiation process and its attendant issues. E.g., Yonathan A. Arbel, On the Scales of Private Law: Nano Contracts, 37 HARV. J. L. & TECH. (forthcoming 2024). 4 For a skeptical view, see Douglas G. Baird, The Boilerplate Puzzle, 104 MICH. L. REV. 933 (2006). 5 On the rapid rise in AI capabilities on a variety of tasks, see Yonathan A. Arbel, Matthew Tokson, Albert Lin, Systemic Regulation of Artificial Intelligence, 56 ARIZ. ST. L. REV. (forthcoming 2024). Electronic copy available at: https://ssrn.com/abstract=4491043 <> ARBEL & BECHER HOW SMART ARE SMART READERS? 4/41 through non-technological means. If they cannot, however, regulation may be justified in relying on non-technological tools. To frame our analysis, we offer a brief background on smart readers and their relevance to the no-reading problem in Section II. In Section III, we describe our dataset and methodology. We present the results of our examination at the level of the entire agreement, comparing the complexity, length, readability, and quality of the legal documents before and after their simplification in Section IV. Then, in Section V, we shift the focus from the entire legal text to (eight) specific clauses, allowing for a more in-depth and digestible analysis of the models’ capabilities, advantages, and limitations. In Section VI, we discuss the key insights of this study. We find that smart readers perform well on both quantitative and qualitative metrics. They cut in half text difficulty, shorten long texts considerably, and generally capture the most important or intricate aspects of the original texts they simplify. Yet, smart readers also struggle with some types of clauses and sometimes understate, omit, or provide incorrect information on some contractual aspects. In all, smart readers do not replace the careful eye of an experienced lawyer, but they can address consumer problems at scale, cheaply, efficiently, and effectively. In other words, we find that smart readers have arrived. II. SETTING THE SCENE: LLMS & THE NO-READING PROBLEM While most scholars believe that consumers do not read form contracts and privacy policies (the “no-reading problem”), the reason for this phenomenon is not quite settled. Why do consumers abstain from reading? Scholars have offered several explanations. Some focus on rational apathy, with not reading emerging as a rational strategy considering the immediate and real costs of reading against the uncertain future gains of doing so. Consumers may also misperceive contract terms or ignore them altogether if they are prone to myopia, information overload, or other forms of behavioral biases.6 The take-it-or-leave-it nature of most form contracts also makes reading unattractive for negotiation purposes.7 Other explanations for consumers’ tendency to not read form contracts relate to 6 See OREN BAR-GILL, SEDUCTION BY CONTRACT: LAW, ECONOMICS, AND PSYCHOLOGY IN CONSUMER MARKETS (Oxford Univ. Press 2012). 7 See Nat’l Lab. Rels. Bd. v. Gen. Elec., 418 F.2d. 716, 768 (2d Cir. 1969), cert. denied, 397 U.S. 965 (1970) (characterizing a “take-or-leave-it” approach as a “hard position” that “may be unattractive"). Electronic copy available at: https://ssrn.com/abstract=4491043 <> ARBEL & BECHER HOW SMART ARE SMART READERS? 5/41 reputational constraints, trust and social norms, and a (sometimes misguided) belief in the courts’ reluctance to enforce unreasonable terms.8 However, perhaps the most influential accounts relate to the writing itself. Consumer form contracts are cognitively taxing, visually difficult, and replete with blocks of off-putting ALL-CAPS while employing arcane terms, complex language, and difficult concepts.9 Consumers do not read contracts, in short, because reading them is a miserable experience.10 These challenges lead to a central problem in unregulated markets. Namely, if consumers do not read forms and the law generally allows them to proliferate, firms can insert self-serving terms without losing demand.11 This situation gives rise to a winning strategy we dub HIDE. Under HIDE, firms adopt forms that are “Hardly Interpretable but Dependably Enforceable.” The HIDE strategy allows firms to benefit from both worlds: maximizing their share of the transactional surplus while reaping the benefits of legal enforcement.12 To deal with HIDE and increase the legitimacy of consumer form contracts, scholars, regulators, courts, and advocates have sought solutions to make contracts more readable and accessible and consumers’ assent less questionable. Courts, in a perhaps naïve attempt to incentivize consumers to read, often impose a so-called duty to read.13 At the same time, lawmakers around the country have instituted hundreds of plain language laws.14 The UCC famously conditions enforcement of warranty disclaimers on their formatting and 8 The literature here is vast. See, e.g., Yonathan A. Arbel & Roy Shapira, Theory of the Nudnik: The Future of Consumer Activism and What We Can Do to Stop It, 73 VAND. L.

Agency action is also involved. For instance, the CFPB recently published new guidelines on what counts as abusive behavior, which includes ‘buried disclosures’ broadly understood to include ‘the use of fine print, or complex language’.18 Such regulations cover broad markets and are quite influential. A prominent example comes from insurance markets. Here, some states and government agencies have adopted not only plain language requirements but also required specific scores on reading metrics, such as the Flesch-Kincaid readability metric.19 While well-intentioned, these policies have an uneasy fit to those anonymous mass transactions that typify the consumer experience. Consumers are diverse, and their cognitive and linguistic skills, education, socioeconomic status, life experience, expectations, and visual acuity can differ significantly. Millions of American adults struggle with literacy, for diverse reasons.20 The idea of plain language homogenizes consumers, supposing that a single serving of simpler words can address the needs of a diverse group. But, in reality, such reforms come at a cost and do not necessarily help those who need protection most. At the same time, writing legal texts that would be readable by those with low literacy is a challenge to the best of writers. Furthermore, plain language efforts often do not address the issue of length: consumers are likely to avoid reading plain language contracts if their length is excessive, and few regulatory frameworks limit the length of legal texts. Enter smart readers. In 2021, we noticed that the emergent transformer technology shows real promise in processing text in general and legal texts in particular. GPT-2, and later GPT-3, could interact with natural language in ways not conceivable before. The feasibility of developing smart readers— that is, 15 U.C.C. § 2-316. 16 15 U.S.C. § 2301 et seq. 17 15 U.S.C. § 1601. 18 CONSUMER FIN. PROT.

Instead of serving an abstract average or reasonable consumer, smart readers could tailor the text to specific, ad-hoc, personalized, or idiosyncratic needs of the individual user. Most promising, the technology was almost entirely consumer-sided. The seller was not part of the process, and any HIDE strategy they might pursue was now challenged. Consumers could have control. Smart readers could penetrate the dense language thicket; each contract could be tailored to the individual consumer. To be sure, the technology in 2021 was nascent. The models we used were quite clunky and success was sporadic.23 To showcase its potential, we had to cherry-pick examples, a fact we explicitly noted.24 GPT-3 produced outputs that were sometimes unreliable and misleading, while other times they were meandering and irrelevant.25 Understandably, when we presented our work, commentators were often skeptical. One reason for their skepticism was that the technology’s inconsistency meant consumers cannot reliably trust it. There were also understandable concerns about the ability of this technology to separate the wheat from the chaff, work at scale, parse complex texts, account for specific legal knowledge, and avoid capture by sellers. We could not provide hard proof that these issues were temporary. However, the arc of this technology was clear to those immersed in the technical details of how it worked. The problems salient back then were true issues, but they related to insufficient data and compute resources,26 rather than a missing intellectual breakthrough. At the fundamental level, it was clear that these issues were transient. At the time of writing this manuscript, the latest state-of-the-art model (GPT- 4) has moved from previous generations’ worse-than-guesswork on the MBE 21 Yonathan A. Arbel & Shmuel I.

GPT-4 has blazed through the LSAT (88th percentile) and medical exams (75th percentile).28 It achieved good scores on challenging economics and advanced quantum physics exams.29 Most importantly, the sentiment changed. While the technology is imperfect in many ways, it became apparent that its current achievements do not represent all of its potential. Indeed, the main question commentators and the public ask today is not what the technology can do, but what it cannot.30 The rate of mass adoption of ChatGPT has surpassed almost any other technology or invention.31 Versions of LLMs are now accessible to the end user free of charge. The technology requires little expertise to use. Most of all, the technology is impressive. From a law and policy perspective, the time is ripe to evaluate whether smart readers could empower consumers and solve the no- reading problem.32 III. DATASET AND METHODOLOGY Dataset.

Our examination focuses on three key criteria at the heart of the no-reading problem. First is text readability. As noted, many suspect that unreadability deters consumers from reading. Therefore, we sought to examine whether language models can make consumer form contracts and privacy policies more readable. The most famous readability measure is the Flesch Ease of Reading test, which assesses text readability on a 0-100 scale.34 This test was later amended to convert the scores to a grade-level equivalent, resulting in the Flesch-Kincaid variant.35 Microsoft users might be familiar with these readability tests, which are embedded in Word.36 This test is joined by a battery of other tests: Gunning- Fog, SMOG, Linsear-Write, Automated Readability, and Dale-Chall.37 The common ground shared by these tests is that they abstract from the meaning strata of the text and evaluate it based on syntactic features, most commonly sentence length, word syllabicity, and word rarity. These measures are widely used but have been recently critiqued for their limited reliability and validity.38 One special concern is that these tests are highly manipulable. By choosing a different implementation of the Flesch-Kincaid test one could obtain results that show the same text requires 4.6 extra years of schooling.39 To limit 33 Because the terms and privacy policies referenced here were retrieved with New Zealand IP address, they have been posted on the author’s own website for permanency.

Electronic copy available at: https://ssrn.com/abstract=4491043 <> ARBEL & BECHER HOW SMART ARE SMART READERS? 10/41 these issues, we use the Combined Readability Measure (CRM), which measure averages within implementations of the same test and across a number of readability measures. This approach smooths test difference and produces results that are, at the very least, far less manipulable. The second criterion we assess is text length. Consumer contracts and privacy policies grow longer over time, and there is reason to believe that lengthy texts dissuade consumers from reading. Accordingly, we analyzed the language models’ ability to shorten the sampled eight legal documents. Finally, even if language models can shorten and simplify legal texts, there is still the concern that this will come at the expense of meaning and context. In other words, simplifying a text can result in losing key facts, important details, nuances, and context. Therefore, our third criterion is text quality. Here, we sought to evaluate to what extent the simplified summaries captured the important legal aspects, risks, obligations, and rights. Simplification tools: challenges, selection, and programming. While some services offer AI-powered summarization, none specialize in contracts. Aiming to fully understand and control the summary process presented three technical challenges. We discuss them in turn. First, many language models are available to select from and each has different limitations on context size and a different mode of interaction (aka Application Programming Interfaces (APIs)). We addressed this issue by selecting the best models that could be used inexpensively. We believe this simulates well the future direction of smart readers, where they will not necessarily rely on state-of-the-art technology to contain costs. The models we picked, however, were all competent models by today’s standards, and, hence, offer a good representation of current capabilities. These models came from two firms: Anthropic (Claude) and OpenAI (ChatGPT). The second challenge we encountered was that current models have constraining limits on input length, meaning that we could not process the entire contract at once. We handled this challenge by developing our own smart reader. In essence, the code we developed performs the following tasks: (1) Handle the communication mode with the various models (API); (2) Code for each model its limitations on input length; Electronic copy available at: https://ssrn.com/abstract=4491043 <> ARBEL & BECHER HOW SMART ARE SMART READERS? 11/41 (3) Divide the text into ‘chunks’ that fit the input length limitations;40 (4) Define in code our prompt for the task; (5) Use a new Python library called ‘langchain’;41 the code iteratively asks the models for simplification of the relevant chunks; and (6) Use the code to combine the chunks together into the resulting simplified contract. The third challenge involved devising a specific prompt that would ensure our goals as described above: (1) no loss of information, (2) simpler language, and (3) shorter language. Devising this prompt was arguably the most critical aspect in our design since the wording of the prompt can radically change the quality of the output generated by the model. But because there are no robust prompt optimization algorithms that we could use, we relied instead on trial and error. After some experimentation, we decided on the following prompt: Simplify contract, low Flesch Kincaid score, KEEP MEANING. Use short words, not legal terms. Swap: accomplishment=success, responsibility=duty, extravagant=fancy. Keep necessary legal concepts. Short sentences. Preserve legal aspects. NO COMMENTS. It is worth noting three points regarding the prompt. First, the prompt was shorter than we wanted, but it was necessary to keep it short to limit the burden on the maximum input length. It is possible that a more elaborate prompt would yield better outcomes. Second, the prompt aims to ensure the model prioritizes certain objectives using capitalization. Third, the prompt uses a few examples, which is known to increase model performance. Analysis. Our analysis proceeds in three phases. First, we test the ability of smart readers to simplify the contracts and policies using objective metrics. As detailed in part IV.A, these included length, complexity, and readability. Second, we assess the quality of the summaries and the extent to which they capture key information. To that end and as we explain in more detail below,42 we use Spotify’s Terms of Use as a sample contract and identified specific important 40 Chunking is not a trivial task, since cutting off a document in the middle risks disrupting its meaning. This risk is especially true for cutting off in the middle of a sentence, but is also true for other cutting criteria given textual inter-dependence. Our chunking algorithm divided the document into sentences and then made sure each chunk only had full sentences. A more robust system would have divided the document into clauses, but besides the technical difficulty of detecting clause limits, even this approach would cut off inter-clause dependencies. 41 Introduction | LangChain, LANGCHAIN, https://python.langchain.com/en/latest/index.html (last visited July 24, 2023) [https://perma.cc/LM58-BUSQ]. 42 See Part IV.B. Electronic copy available at: https://ssrn.com/abstract=4491043 <> ARBEL & BECHER HOW SMART ARE SMART READERS? 12/41 contractual aspects and possible consumer traps. We then assess the extent to which two simplification outputs included the issues we spotted in their summary. Third, we examine in-depth the simplification of eight specific clauses. Whereas Part V focuses on the high-level results, Part V outlines the analysis process of the specific terms, its results, and our evaluation. IV. HIGH-LEVEL RESULTS We now detail our general results. In Section A, we discuss the simplification assessments. Using common tools, we objectively measure text length, complexity, and readability. We supplement these objective metrics in Section B, where we detail our subjective impression of two of the simplifications and their ability to capture key information. A. Simplification Assessment 1. Text Length We started by measuring the reduction in words. On average and across all contracts, the various models produced a text that was about 30% of the length of the original in terms of words. In terms of reading time,43 if the original version would take on average 20 minutes and 45 seconds to read, the simplified version only takes 6 minutes and six seconds, a time-saving of 14 minutes and 39 seconds. The following figure summarizes the average effect across all agreements and models. 43 Based on Marc Brysbaert, How Many Words Do We Read Per Minute? A Review and Meta-Analysis of Reading Rate, 109 J. MEMORY & LANGUAGE 1, 21 (2019) (the average adult reads at a rate of 238 words per minute for non-fiction texts and 260 words per minute for fiction ones). As suggested to us by Professor Tim Samples, the reading time for difficult texts is longer, and by the same source it is estimated as 238 multiplied by 4.6 divided by the mean word length. The following Figure includes this method of analysis. Electronic copy available at: https://ssrn.com/abstract=4491043 <> ARBEL & BECHER HOW SMART ARE SMART READERS? 13/41 Figure 1: Length Reduction (in Thousand Words) Figure 4: Text Readability Flesch-KincaidFigure 2: Length Reduction (in Thousand Words) Another notable feature of the models is their great variability. Despite employing a similar prompt, the models produced wildly different results. While all models did well in terms of summarization, the worst one (Davinci-001) saw a reduction of 49%, while the best one (Curie-001) decreased 88.4% of the original length. And while all models perform admirably, the longest version was three times longer than the shortest one. In other words, there is a large degree of inconsistency between models. The following figure aggregates the reduction across all documents to provide an overview of the average reduction in the number of words and sentences, as well as the required reading time. Figure 2: Aggregated Reduction Results: Words, Sentences & Reading Time 2. Text Complexity One way to assess the simplification of text is by a count of difficult words in the text before and after simplification. Although there is no single way to Electronic copy available at: https://ssrn.com/abstract=4491043 <> ARBEL & BECHER HOW SMART ARE SMART READERS? 14/41 measure word difficulty, we relied on the word list compiled for a famous readability test: Dalle-Chall.44 This list is admittedly somewhat limited and not tailored to legal jargon. However, it is adequate for our purposes of assessing differences between versions (rather than the absolute number of difficult words). The Figure below shows the number of difficult words in the different documents. The red bar shows the number of difficult words in the original text and the purple bar summarizes the average number of difficult words across the various models. Across all documents, we note an average reduction of 328 difficult words, representing a 61% reduction. As before, there is great model variability in simplification. Still, even the worst model (DaVinci-001) substantially reduced the number of difficult words, removing 36% of them. Figure 3: Difficult Words 3. Text Readability There is more to text readability than difficult words, and the literature on readability has developed several quantitative tools to measure readability.45 As discussed above, we report on the results of the famous Flesch-Kincaid score and the average of a number of readability measures (CRM).46 44 See Common Education Data Standards, supra note 37. We implemented this word list via the Textstat library in Python. 45 See id. (listing out different readability tests). 46 The results stem from the mean of popular Python libraries that implement readability tests: textacy, textstat, textexplore, readcalc, pylexitext, and readability.

That said, there was great variability among the models, with the best performing model (Claude-001) reducing the reading level by an average of 5.6 grade levels, down to a 5.4 grade level. This reduction would make contracts accessible to 11-year-olds. This improvement is quite important as a large body of scholarship recommends that reading materials be accessible to people who read between the sixth to eighth grade level.48 Figure 5 below provides similar numbers with the CRM measure. The average reduction on the CRM was more modest, with close to a single grade level. However, here too, the best performing model (Claude-001) did very well and reduced the reading level by 5 grade years, down to a level close to the seventh grade (that is, a 6.8 grade level).

Electronic copy available at: https://ssrn.com/abstract=4491043 <> ARBEL & BECHER HOW SMART ARE SMART READERS? 16/41 Figure 5: Text Readability CRM Quite surprisingly, despite our prompts, some models have made them more complex. Yet again, the models have had mixed success in simplifying the contracts. The most consistent models were Claude-001 and Text-Davinci-003, a finding consistent with them being the most advanced in our group. B. Quality Assessment To develop a better sense of the quality of the outputs generated by LLMs, we supplemented our metric-based examination above with a more subjective evaluation. Essentially, we compared the first parts49 of an original text— Spotify’s Terms of Use—with two simplified outputs, produced by ChatGPT- Turbo and Claude. Particularly, we sought to examine whether the simplified versions captured the key issues and points we identified in the original text. We started by reading the original text and highlighting clauses likely to be of special importance for unwary consumers. We detected 11 central or tricky points (dubbed here “traps”). We then read the two simplified versions, examining whether these versions properly mentioned the identified 11 key points. We also noted our general subjective impression of the texts’ quality, presentation, and user-friendliness. 49 By first parts, we mean clauses one to three, which contained 2,360 words. Electronic copy available at: https://ssrn.com/abstract=4491043 <> ARBEL & BECHER HOW SMART ARE SMART READERS? 17/41 Overall, we found that both platforms made the contracts much simpler and captured most of the important information. However, significant differences were evident between the two outputs in terms of length, visual presentation, and the use of bullet points. The visual presentation, however, should not be emphasized. It was more an artifact of the way we coded the smart reader than a technological challenge. With more resources, we can produce a smart reader that will organize the text, use bullet points, and even engage in creative design, including colors and comic-style graphics. In addressing the 11 traps, both models performed reasonably well, albeit with somewhat varying degrees of success. Both models captured most, but not all, traps and important information in their summaries. For example, ChatGPT Turbo included 9 of the 11 traps in its summary. Interestingly, one of the traps that Claude omitted overlapped with one of these two missing traps. This finding has two implications. First, if some models fail to address certain issues, another model better at detecting them can supplement them (the ‘ensemble’ method). Second, there is room for research into the possibility that current LLMs might systematically miss some types of information. In general, we observe that some of the omissions and presentation issues we encountered are due to the need to cut the original texts into smaller chunks. This “chunking” strategy is common today, but it is imperfect.50 It interferes with the flow of the text and cuts context, an especially important concern in interdependent contracts. With time, input length will not pose as much of an issue, so the flaws associated with this specific problem are transient. This broad review allowed us to develop a general sense of quality. However, it did not capture some of the subtleties of simplification. To that end, we next analyzed specific clauses. V. SIMPLIFICATION & QUALITY: SPECIFIC CLAUSES To develop a more robust understanding of the capability of smart readers to produce high-quality simplifications, we next shifted our focus from the entire contracts to specific clauses within them. We chose to focus on eight specific terms that may pose challenges for the unsuspecting consumer. That is, rather than measuring performance on random clauses, some of them potentially trivial, 50 Alberto Artasanchez & Prateek Joshi, Assessing Text Through Bag of Words Model in Natural Language Processing, MEDIUM (June 9, 2020), https://odsc.medium.com/assessing-text-through-bag-of- words-model-in-natural-language-processing-9654f17abf56 [https://perma.cc/VY45-KSG2]. Electronic copy available at: https://ssrn.com/abstract=4491043 <> ARBEL & BECHER HOW SMART ARE SMART READERS? 18/41 we actively selected clauses that we thought mattered for consumers. These included, for example, clauses that address cancelation, information sharing, liability limitation, dispute resolution, and unilateral modifications. Because this focus resulted in relatively short texts (i.e., specific clauses), we could effectively use GPT-4, the current state-of-the-art model. For consistency, we used the same prompt as before. In what follows, we delineate the contract clauses we examined. For each clause, we provide the original text, followed by the simplified version offered by GPT-4. We then evaluate the simplification in terms of length, complexity/readability, and quality. A. Wall Street Journal: Changes to Subscriber Agreement Original51 1.

The changes also will appear in this document, which you can access at any time by going to the Subscriber Agreement and Terms of Use link at the footer of those Services which are made available through a website or to the Legal or Legal Notices area of those Services which are made available as an application. By using a Service after changes are made to this Agreement you signify that you agree to be bound by such changes. Simplified 1.

We’ll let you know about these updates, either in writing or digitally (like by email or posting an update notice on the Service). These updates will be added to this document. You can find it anytime by clicking on the Subscriber Agreement and Terms of Use link at the bottom of any website-based Services, or in the Legal area of any app-based Services. If you keep using a Service after we update this Agreement, it means you accept these updates. Evaluation This clause allows the service provider to change the terms of the agreement unilaterally, an issue of considerable import for consumers.52 We find the simplification to be highly effective. It uses the second person to refer to the 51 WSJ Terms, supra note 33. 52 E.g., Shmuel I. Becher & Uri Benoliel, Sneak In Contracts, 55 GA. L. REV. 657, 657 (2021) (asserting that unilateral modifications can “affect virtually every aspect of a contract”); see also David Horton, The Shadow Terms: Contract Procedure and Unilateral Amendments, 57 UCLA L. REV. 605, 645 (2010) (describing how unilateral amendments give drafters “a kind of contractual dexterity”). Electronic copy available at: https://ssrn.com/abstract=4491043 <> ARBEL & BECHER HOW SMART ARE SMART READERS? 19/41 reader. It starts the paragraph with a thesis statement (as in TRIAC and other writing conventions)53 and offers a direct summary of the effect of the clause. While generally true to the original, there is yet a subtle issue here. In the original, changes to the contract are only effective if communicated. In the simplified version, it is implied that changes are done unilaterally, and some users may infer that communicating those changes is more of a courtesy than a prerequisite. If a firm makes uncommunicated changes to its agreement, the simplified version may mislead the consumer into thinking that the changes are effective. Still, the difference is not large, and the actual meaning of “we will let you know about these updates” (as per the simplified version) may be somewhat ambiguous. Either way, the rest of the paragraph is well-executed. The quantitative analysis depicted in Figure 6 shows a reduction of nearly 7.5 grade levels on the Flesch-Kincaid measure and 8 grade reduction on the average of scores of the various readability measures. In either case, the text is evaluated as readable by an eighth-grader. Furthermore, the simplified version reduced 26% of the text, cutting the number of words by 33 (out of 127).54 The number of sentences doubled from three to six due to splitting long sentences into shorter ones. Consistently, the average word length, although not depicted (in this and the following figures), falls from 5.17 characters to 4.45. 53 Eric Drown, TRIAC Paragraph Structure, UNIV.

Decisions from arbitration can be used in any federal or state court in New York County, State of New York. By agreeing to this, both you and we give up the right to a jury trial, except for the cases we just noted. The arbitrator will deal with issues one by one; group arbitrations and group actions aren’t allowed. We agree that this arbitration process, based on New York law, will still apply even after this Agreement ends. 14.2 Unless we both say otherwise, the arbitration will happen either where you live or in New York County, State of New York. For claims of $14,000 or less, you get to pick how the arbitration will be done: only by looking at submitted documents, through a meeting in person, or by phone. 14.3 The arbitrator can award money or make fair changes in favor of only the person asking for it and only to the level needed to provide help based on their claim. The arbitrator won’t provide a reason for the decision unless both parties ask. The arbitrator won’t deal with more than one person’s claims at a time unless both you and we agree otherwise.

First, perhaps by virtue of the prompt’s insistence on a change of terms, it replaced the heading ‘Agreement to Arbitrate’ with ‘Solving Disputes.’ While the latter communicates better, it does not make the term arbitration sufficiently salient. Relatedly, some choices of words may implicate different legal consequences. The model translated intellectual property to “ideas.” This change is quite wrong: not all ideas are subject to IP, and this may give a sense that more disputes belong in courts than the original agreement allows. Yet again, the problem here may stem from our prompt, which insisted on using simpler terms. A similar issue afflicts the choice of “group actions” instead of “class actions” and the language suggesting that arbitration awards can be “used” rather than “entered.” In terms of quality, a worrisome omission is that the original clarifies that the customer may still bring complaints to state or federal agencies. The simplified version does not mention that. This omission can deprive the customer of important rights. A final issue is that the model translated equitable relief to “fair changes.” These two ideas differ, and the simplified version could mislead. Yet, the dilemma of simplification of this term is quite pressing, and the average consumer may find both terms ambiguous. It is hard to effectively translate equitable relief—which may consist of in-kind remedies, injunctive remedies, apologies, and other measures—to a simple term. At the same time, keeping the original term would sacrifice the ability of laypeople to parse it. All in all, this simplification is disputable but not irrational. On the quantitative measures, we see a dramatic reduction in grade level evaluated for the reading of the agreement. Again, the simplification transformed an agreement readable by PhDs into one readable by eighth-graders.

If you link, connect, or login to the Airbnb Platform with a third-party service (e.g., Google, Facebook, WeChat), you direct the service to send us information such as your registration, friends list, and profile information as controlled by that service or as authorized by you via your privacy settings at that service. • Background Information. For Members in the United States, to the extent permitted by applicable laws, we may obtain, for example, reports of criminal records, sex offender registrations, and other information about you and/or your background. For Hosts in India, to the extent permitted by applicable laws, we may perform criminal background checks. For Members outside of the United States, to the extent permitted by applicable laws and with your consent where required, we may obtain police, background, or registered sex offender checks.

If you are invited to the Airbnb Platform, for example, as a co-traveler on a trip, the person who invited you can submit personal information about you such as your email address or other contact information. • Guest Travel Insurance. If you make a claim under our Guest Travel Insurance policy, we will receive information regarding your claim in order to process, handle, or assess your claim and as outlined in this Privacy Policy. • Other Sources. To the extent permitted by applicable law, we may receive additional information about you, such as references, demographic data, or information to help detect fraud and safety issues from third-party service providers and/or partners, and combine it with information we have about you. For example, we may receive background check results or fraud warnings from identity verification service providers for use in our fraud prevention, security investigation, and risk assessment efforts. We may receive information about you and your activities on and off the Airbnb Platform, or about your experiences and interactions from our partners. We may receive health information, including but not limited to, health information related to contagious diseases. Simplification 2.4 Info We Get from Other Sources. We get personal info from other places like: • Other Services. If you connect your Airbnb account with a service like Google, Facebook, or WeChat, you allow them to send us certain info like your registration and profile details. • Background Checks. In the US, we might get reports on criminal records and other background info. In India, we might run criminal background checks on hosts. In other countries, we might get police or background checks if the law allows and you agree. • Invites and Co-travelers. If someone invites you to Airbnb, like to join a trip, they might give us your contact info. • Guest Travel Insurance. If you make a claim under our travel insurance policy, we get info about your claim. • Other Places. If the law allows, we might get more info about you from other service providers or partners, and mix it with the info we already have. This could be background checks, fraud warnings, info about your activities on and off Airbnb, and even health info related to infectious diseases. Evaluation This provision delineates the categories of personal data that Airbnb collects from third-party sources, which is another important practice for consumers to understand. The simplification has successfully distilled the original provision’s complex legal language into more accessible terms without distorting the overall Electronic copy available at: https://ssrn.com/abstract=4491043 <> ARBEL & BECHER HOW SMART ARE SMART READERS? 25/41 meaning. The use of “other sources” instead of third-party services is quite helpful, and the use of “info” instead of information may be grammatically inaccurate yet useful (or at least understandable). However, certain points could be clearer and more comprehensive. For instance, the simplified version omits the example that some of the information shared may contain the user’s friends list. This omission is not misleading per se, but we suspect that consumers may not otherwise expect Airbnb to share this information with third-parties. As for background checks, the simplification converts “with your consent where required” to a proposition that implies that consent will always be sought. This modification is misleading because sharing will sometimes occur without consent. An arguably more minor omission regards information sharing with the insurer. The simplified version does not mention that the privacy policy limits information sharing; i.e., it gives a sense that information sharing is unlimited. The quantitative measure shows another substantial improvement, reducing the readability level from college level to sixth or seventh grade. Furthermore, the word count has declined by 50%: from 370 words to 185. This drop included a minimal decrease in the number of sentences (from 16 to 15) and moderate reduction in the average word length (from 5.04 to 4.33).

Cancellation. You can cancel your Netflix membership at any time, and you will continue to have access to the Netflix service through the end of your billing period. To the extent permitted by the applicable law, payments are non- refundable and we do not provide refunds or credits for any partial membership periods or unused Netflix content. To cancel, go to the “Account” page and follow the instructions for cancellation. If you cancel your membership, your account will automatically close at the end of your current billing period. To see when your account will close, click “Billing details” on the “Account” page. If you signed up for Netflix using your account with a third party as a Payment Method and wish to cancel your Netflix membership, you may need to do so through such third party, for example by visiting your account with the applicable third party and turning off auto-renew, or unsubscribing from the Netflix service through that third party. Simplification 3.4. Ending Your Membership. You can stop your Netflix membership whenever you want. You’ll still be able to use Netflix until the end of your billing cycle. Under current law, we can’t refund payments and we don’t give refunds or credits for part of a membership period or for unused Netflix content. To stop your membership, visit the “Account” page and follow the steps there. If you stop your membership, your account will close at the end of your billing cycle. To find out when that is, click “Billing details” on the “Account” page. If you joined Netflix using a third party for payment and you want to stop your membership, you may have to do this through that third party. This might involve turning off auto-renew or unsubscribing from Netflix through them. Evaluation This provision governs the cancellation of a Netflix subscription, yet another tricky issue in consumer contracts.59 The simplification seems to maintain the overall integrity of the original paragraph while making it more accessible to the reader. However, there is a misinterpretation of the refund policy that could potentially mislead consumers. The original text states that Netflix’s general policy is not to provide refunds or credits for any partial membership periods or unused Netflix content, but that 58 Netflix Terms, supra note 33. 59 Cf.

Electronic copy available at: https://ssrn.com/abstract=4491043 <> ARBEL & BECHER HOW SMART ARE SMART READERS? 27/41 the firm can make exceptions to the extent permitted by applicable law. This text suggests that in some jurisdictions, Netflix may indeed be required to issue refunds. In contrast, the simplified text asserts that “under current law, we can’t refund payments.” This language indicates that Netflix is legally prohibited from providing refunds. This erroneous interpretation potentially miscommunicates Netflix’s refund policy to consumers, particularly those residing in regions where laws may, in fact, mandate refunds. This difference is a major issue that can mislead consumers and undermine their rights. The quantitative measure shows another significant improvement, setting the readability level at between the sixth and seventh grade (instead of the high school level required for reading the original). At the same time, the word count has only declined by 16% (from 163 to 137). This included a small increase in the number of sentences (from 8 to 10), and a slight decrease in the length of words (from 4.82 to 4.47). Figure 9: Clause Simplification, Netflix E.

Electronic copy available at: https://ssrn.com/abstract=4491043 <> ARBEL & BECHER HOW SMART ARE SMART READERS? 29/41 Evaluation This provision governs content contribution to the platform, most notably in the form of reviews. This provision raises an important issue since consumers often rely on online reviews and use them in their decision-making. Hence, ensuring reliable and robust online information flows is crucial in disciplining sellers and maintaining efficient markets.61 Overall, we find the simplification above to be effective. However, some issues require attention. First, the simplified version leaves out a few important restrictions. It fails to mention the prohibition on email spoofing and political campaigning explicitly mentioned in the original, thereby providing less comprehensive guidance to users. At the same time, the original possibly contained too many illustrations, so the balance is delicate. Second, the contract contains an important clause about the warranties provided by users when they post content, which is especially weighty in its implications. Users have to guarantee the accuracy of their reviews and ensure that these reviews will not harm others. This requirement could be burdensome to users and is quite unexpected, given that truthful reviews may well harm unscrupulous, negligent, or underperforming sellers. The simplification communicates most of it, but perhaps a more formal tone might be beneficial in highlighting the gravity of these obligations. This difference potentially points to a deeper problem at the heart of the simplification project: whereas simplification often entails a more casual or flippant tone, formality is sometimes a good signal of the gravity of obligations.62 By readability metrics, this was the most complex original text so far. The reduction from 19-20 years of education to a level readable by an eighth grader is, therefore, quite impressive. Also, the length fell by 26% (from 304 words to 226). This dip was nonetheless accompanied by an increase in the number of sentences (from 8 to 12), which, as noted, often results from text simplification 61 See Shmuel I. Becher & Tal Z. Zarsky, E-Contract Doctrine 2.0: Standard Form Contracting in the Age of Online User Participation, 14 MICH. TELECOMMS. & TECH. L. REV. 303, 333 (2008) (viewing accreditation issues in terms of reliability and trustworthiness as challenges to online information flow); Arbel & Shapira, supra note 8, at 952 (asserting “reputational information is too often unreliable”); Yonathan A.

REV. 1239, 1275 (2019) (explaining why statistically reviews are unreliable as “sole guides for consumer decision-making”). 62 Arbel and Toler test this and do not find evidence to support the red-flag theory of formality, yet in the context of a fairly specific intervention.

Finally, word length fell from 5.17 to 4.33 characters per word. Figure 10: Clause Simplification, Amazon F. Amazon: Risk of Loss Original63 RISK OF LOSS All purchases of physical items from Amazon are made pursuant to a shipment contract. This means that the risk of loss and title for such items pass to you upon our delivery to the carrier. RETURNS, REFUNDS AND TITLE Amazon does not take title to returned items until the item arrives at our fulfillment center. At our discretion, a refund may be issued without requiring a return. In this situation, Amazon does not take title to the refunded item. For more information about our returns and refunds, please see our Returns Center. Simplification LOSS RISK When you buy physical items from Amazon, they are yours once we give them to the carrier for delivery.

Electronic copy available at: https://ssrn.com/abstract=4491043 <> ARBEL & BECHER HOW SMART ARE SMART READERS? 31/41 Evaluation This clause assigns the risk of delivery loss to the customer. Consumers may not expect such a clause, as they have little control over Amazon’s shipping methods. Indeed, some jurisdictions regard contract terms that relieve the supplier of responsibility, which they would have to bear under law or by virtue of the contract (if not for that term), as presumably unfair.64 The simplification preserves the overall meaning, but it could do better in highlighting key customer responsibilities and exceptions. It effectively communicates that the items belong to the buyer upon delivery to the shipper. However, it does not communicate clearly enough that the customer bears the risk if something goes wrong with the delivery. The same criticism, but to a lesser extent, applies to returns. The proposed simplification, “If you return something, it’s not ours until it gets to our fulfillment center,” does not adequately communicate the contractual risk allocation, such as what happens if items are lost in the return process. On the positive side, we note the effectiveness of using “you still own” relative to “take title.” Figure 11 depicts the most modest improvement in readability so far. Readability improved by just a single grade level, but that is likely because the original is both short and relatively simple. Still, we believe greater improvements could take place with additional prompting. Likewise, the change in length was also relatively less substantial, with a 23% reduction (from 95 words to 73). There was no change in the number of sentences and a marginal change to the word length, falling from 4.64 to 4.45. 64 See, e.g., Standard Contracts Law, 1982, LEVITANSHARON & CO., https://www.israelinsurancelaw. com/standard-contracts-law-1982/ (last visited July 24, 2023) [https://perma.cc/6QNG-MJJX] (listing out various sections of the contract code in Israel, particularly sections 3 and 4, which treat provisions that relieve supplier’s responsibilities as per se unfair).

Electronic copy available at: https://ssrn.com/abstract=4491043 <> ARBEL & BECHER HOW SMART ARE SMART READERS? 34/41 Evaluation This provision governs Yahoo’s information sharing, an important aspect of today’s markets and economies.66 The specific challenge here is that the original has inconsistent logic. For example, it says that personally identifiable information about customers will not be shared without consent unless it is with advertisers with whom personally identifiable information can be shared even without consent. Overall, the clause attempts to set rules that allow Yahoo to share all information in various ways and personally identifiable information in limited ways. We find that the simplification captures this intended logic, although even the best simplification may not overcome the difficulty of parsing what it means for Yahoo to allow for cookie matching with partners without letting them access their cookies. This example provides a more general, important (yet straightforward) insight: AI simplification has limited value if the original legal documents are not properly drafted. Slightly restated, firms might circumvent smart readers and undermine their potential to assist consumers by adopting specific drafting strategies.67 That aside, the simplification is overall helpful. The “you say Okay” is a rather nice touch on “Your consent,” although given the quality of consent required (a checkbox), it may overstate the necessary level of consent. It also omits the confusing cookie-matching policy noted above. More generally, the reduction in text complexity was quite dramatic. The average readability score fell from post-high school level to a level of between seven and eight grade. The length fell by 26% (from 355 words to 264), with a small change to the number of sentences (from 21 to 19). Average word length fell from 5.45 to 4.53 characters per word. 66 Indeed, many scholars have discussed the importance of information sharing.

For clarification, these terms do not limit Spotify’s liability for fraud, fraudulent misrepresentation, death or personal injury to the extent that applicable law would prohibit such a limitation and for any other liability that, by applicable law, may not be limited or excluded. Simplification Based on the law, you agree that the only way to fix any issue or unhappiness with the Spotify Service is to remove any Spotify software and stop using the Spotify Service. You agree that Spotify is not to blame or liable for any issues related to apps from other parties or the content from them available through or linked to the Spotify Service. Even though you might have separate deals with these other parties, your only way to fix any issue or unhappiness with any apps from other parties or the content from them, as far as Spotify is concerned, is to remove or stop using such apps from other parties. Spotify, its staff, shareholders, workers, agents, leaders, child companies, linked companies, future owners, people who take over, suppliers, or those who have a right to give licenses won’t be liable for (1) any indirect, special, extra, punitive, exemplary, or follow-on damages; (2) any loss of use, data, business, or money (direct or indirect), in all cases from using or not being able to use the Spotify Service, devices, apps from other parties, or content from apps from other parties; or (3) total liability for all claims about the Spotify Service, apps from other parties, or content from apps from other parties more than the higher of (a) the amounts you paid Spotify in the twelve months before the first claim; or (b) $30.00. Any liability we do have for losses you go through is strictly limited to losses that could have been reasonably seen coming. Just to be clear, these terms do not limit Spotify’s liability for fraud, wrong representation, death or personal injury to the extent that the law would stop such a limit and for any other liability that, by the law, may not be limited or taken away. Evaluation Liability limitation is a recurring and important theme in consumer contracts, and many jurisdictions treat broad liability limitation clauses with suspicion.69 Unsurprisingly, Spotify’s clause considerably limits its liability. Nonetheless, its wording is inconsistent and confusing. The clause states that the only remedy available to the user is the uninstallation of the app, then moves to limit monetary 69 See, e.g., Council Directive 93/13/EEC, of the European Parliament and of the Council of 5 April 1993 on Unfair Terms in Consumer Contracts, annex, 1990 O.J. (L 95) 29. (paragraph 1b of the annex refers to “inappropriately excluding or limiting the legal rights of the consumer vis-à-vis the seller or supplier or another party in the event of total or partial non-performance or inadequate performance by the seller or supplier of any of the contractual obligations…”). Electronic copy available at: https://ssrn.com/abstract=4491043 <> ARBEL & BECHER HOW SMART ARE SMART READERS? 37/41 remedies to a maximum of $30, and then states that Spotify is liable for anything it cannot disclaim by law. The summary does an overall good job. It delivers the message of the disclaimer in simple language and references the customer to dispute issues with third parties directly. The emphasis that the liability of a third party is limited “as far as Spotify is concerned” is useful in another aspect: It communicates a certain indifference to such harm, and some consumers may find this warning useful. However, there are a few noteworthy issues with the simplification. Perhaps guided again by our prompt, the simplification replaces special terms of art. Thus, it changes “incidental damages” to “extra damages,” “consequential damages” to “follow-on damages,” and “foreseeable damages” to “could have seen coming.” Whereas the simplified version might be better in terms of communication, it unduly alters the legal meaning of the clause. Concerning quantitative metrics, this simplification was the least successful. While it improved readability by seven to eight grade levels, it retained the original structure of the paragraph-long sentence. Readability tests are not well- calibrated to deal with such cases, and the absurd result (28.5 years of schooling exceeds that of almost every lawyer), should be interpreted qualitatively. Furthermore, the simplification made the document marginally longer (from 307 words to 309), suggesting that, at times, text simplification sometimes necessitates more exposition. While there was a slight increase in the number of sentences (from 5 to 6), we observed a reduction in average word length, falling from 5.17 character per word to 4.45.

SIMPLIFICATION OF SPECIFIC CLAUSES: DISCUSSION Our analysis emphasizes the role of two aspects of the simplification process: (a) enhanced accessibility (shorter length, reduced complexity, and increased readability) and (b) quality of simplification. Regarding the former, we note that the simplified clauses did well on all the quantitative metrics. In each case, the improvement in readability metrics was significant; on average, reducing the reader’s required education level by half. While we do not necessarily endorse a literal interpretation of the specific grade level assignment, we do recognize the difference as large and meaningful. At the same time, as the Spotify example illustrates, simplified texts might still be inaccessible by standard metrics. The same applies to length and complexity: While the simplified versions presented a substantial improvement on these dimensions, there is no guarantee that consumers are willing to read even these shorter and less complicated texts. Importantly, the improvement in readability was associated with shorter clauses. This facet is noteworthy, as simplification often requires more exposition. At the same time, the impact on the number of sentences varied, and the effect on word length was relatively mild. However, setting objective metrics aside, we observed an overall significant improvement. The simplified texts were Electronic copy available at: https://ssrn.com/abstract=4491043 <> ARBEL & BECHER HOW SMART ARE SMART READERS? 39/41 more accessible and used simple and direct language, making them easier to read and understand. In terms of accuracy, our report is more mixed. Simplifications of specific clauses were generally accurate and beneficial, especially considering we intentionally chose problematic clauses. Nevertheless, we noticed a range of issues. Some were relatively minor, such as not using a formal tone or failing to include an example that some consumers would find useful. Other issues were more substantial, such as suggesting that consent will be actively sought from the user when it would not, or when omitting the customer’s right to complain to state and federal agencies. An additional significant issue we observed is the incorrect usage of legal terminology. Using “follow-on damages” instead of “consequential damages” entailed more than just confusing the informed consumer. These two concepts of damages are distinct, having very different legal implications. Admittedly, this error may be our own making: the prompt insisted that complex words should be simplified. A less stringent approach would not invite such losses in meaning, although it could compromise the simplification’s effectiveness. Yet, to know whether a given term is a term-of-art or a colloquial term requires some domain expertise, and this may point to a limitation of at least current generation general models. This last point introduces a potentially thorny issue. We generally assume that the canonical contract is the one held by the seller, rather than the one interpreted by the smart reader. However, we wonder if some sellers will persuade the court to adopt the smart reader’s version when it serves them by arguing that this is the version the customer presumably used. If courts follow this path, changes to terms-of-art can be harmful to the buyer. Finally, our analysis did not touch on bias, toxicity, and hallucinations— several issues that afflict current generation models.70 These issues were fairly muted in our analysis, but we do expect them to become relevant as consumers use smart readers more frequently. We thus acknowledge that our inspection is limited in ways that future research may seek to tackle. 70 Kathy Baxter & Yoav Schlesinger, Managing the Risks of Generative AI, HARV. BUS. REV.

SUMMARY Our study suggests that smart readers can substantially shorten legal texts, reduce their complexity, and improve their readability. Our assessment also indicates that smart readers typically identify important information and include this information in their summaries. Overall, it was encouraging and impressive to find that the simplifications did not substantially undermine the quality of the text and the scope of information that consumers receive.71 Thus, if consumers choose to use smart readers, this decision could have significant impact on the viability of HIDE strategies and other market outcomes. The in-depth evaluation of the simplification of specific clauses reinforced our conclusion that while the overall quality of simplification is very high, it is not perfect. However, perfection is not the benchmark. Considerable literature finds that in many domains, consumers rarely read dense legal texts. In such cases, consumers proceed with a vague understanding of the underlying transaction. Provided that smart readers simplify contracts and policies and make them readable, then as long as they are not materially misleading, they can enhance consumers’ decision-making. Specifically, smart readers could potentially facilitate informed decisions, enhance efficiency, and thus encourage competition over terms and pressure sellers to draft better contracts. Furthermore, many consumers may wish to examine legal texts ex post, once or a dispute arises or when encountering an issue with the transaction they entered. Smart readers can serve well these consumers, who are likely to have more tailored queries and specific aspects to decipher. Ultimately, simplification tools do not replace lawyers and do not render the original drafting entirely irrelevant to the end consumer. Still, they offer a marked improvement over current consumers’ realistic alternatives, such as not reading the text and misperceiving legal aspects. Furthermore, our analysis suggests that smart readers may not only serve individual consumers, but also 71 It is worth noting that while our quality assessment was labor-intensive and had subjective aspects, future developments may advance automated tools to evaluate the quality of legal summaries at scale. See, e.g., Bianca Steffes, Piotr Rataj, Luise Burger, & Lukas Roth, On Evaluating Legal Summaries With ROUGE, in PROC. NINETEENTH INT’L CONF. A.I. & L. 475 (2023) (finding that current tools are insufficient for quality evaluation and suggesting to increase the reliability of ROUGE by pre-selecting sentences); see also Huyen Nguyen & Junhua Ding, Keyword-Based Augmentation Method to Enhance Abstractive Summarization for Legal Documents, in PROC. NINETEENTH INT’L CONF. A.I. & L. 437 (2023) (finding that keywords-based augmentation is effective in improving quality and enhancing summarization models).

Notably, we used non-specialized models with little special domain training to deliver these results, which implies that our findings represent a lower bound, rather than an upper limit. It seems more realistic than ever that smart readers will soon have the ability to automatically detect problematic terms, warn consumers about them, evaluate contracts on a scale, compare contracts, and benchmark them.72 Consumers can consult with a smart reader in a Q&A mode, asking questions like “What happens if I don’t pay the balance in full?” or “Can I switch providers when I want to?”. Such advances can transform consumer contracting. Against this revolutionary potential, it is crucial to keep the concerns around accuracy, capture, and bias in mind. Today’s models make errors, and these errors may not be neutral.73 It is possible that as smart readers grow in influence, companies will wish to influence their output or find ways to mislead them or circumvent their potential. It is, therefore, necessary to consider these concerns when evaluating the technology and its trajectory. In this context, massive open- source models may limit the potential for invisible model corruption. Our assessment of current generation models concludes that smart readers have arrived. They are not (yet) a full replacement for careful review by a lawyer. However, for the large mass of contracts and privacy policies that today go unread, they serve as a cheap, effective, and scalable alternative. If their potential materializes, a law and policy paradigm shift would be appropriate, if not inevitable. 72 Combining language models with technologies that can automate the detection of unfair terms in consumer contracts is a promising path to consider. For a study that experimentally examines the use of machine learning platforms to perform such detection, see Marco Lippi, Przemyslaw Palka, Giuseppe Contissa, Francesca Lagioia, Hans-Wolfgang Micklitz, Yannis Panagis, Giovanni Sartor, & Paolo Torroni, Automated Detection of Unfair Clauses in Online Consumer Contracts, 302 LEGAL KNOWLEDGE & INFO.
