"Inspect the file. Read the description of the [data collection methodology](https://www.propublica.org/article/how-we-analyzed-the-compas-recidivism-algorithm). Salient points are highlighted below, with my annotations in **bold font**. See full description from ProPublica for additional details. \n",
"\n",
">**Goal**: We looked at more than 10,000 criminal defendants in Broward County, Florida, and compared their predicted recidivism rates with the rate that actually occurred over a two-year period.\n",
"\n",
">**COMPAS tool input (data subjects)**: When most defendants are booked in jail, they respond to a COMPAS questionnaire. Their answers are fed into the COMPAS software to generate several scores including predictions of *Risk of Recidivism* and *Risk of Violent Recidivism*\n",
"\n",
">**How COMPAS input was acquired by ProPublica**: Through a public records request, ProPublica obtained two years worth of COMPAS scores from the Broward County Sheriff’s Office in Florida. We received data for all 18,610 people who were scored in 2013 and 2014.\n",
"\n",
">**COMPAS tool output**: Each pretrial defendant received at least three COMPAS scores: “Risk of Recidivism,” “Risk of Violence” and “Risk of Failure to Appear. ... COMPAS scores for each defendant ranged from 1 to 10, with ten being the highest risk. Scores 1 to 4 were labeled by COMPAS as “Low”; 5 to 7 were labeled “Medium”; and 8 to 10 were labeled “High.”\n",
"\n",
">**Data integration (record linkage) to matching COMPAS input and output with an individual's criminal history** Starting with the database of COMPAS scores, we built a profile of each person’s criminal history, both before and after they were scored. We collected public criminal records from the Broward County Clerk’s Office website through April 1, 2016. On average, defendants in our dataset were not incarcerated for 622.87 days (sd: 329.19).\n",
"\n",
">**Data integration (record linkage) details**: We matched the criminal records to the COMPAS records using a person’s first and last names and date of birth. This is the same technique used in the Broward County COMPAS validation study conducted by researchers at Florida State University in 2010. We downloaded around 80,000 criminal records from the Broward County Clerk’s Office website.\n",
"\n",
">**What is recidivism?**: Northpointe defined recidivism as “a finger-printable arrest involving a charge and a filing for any uniform crime reporting (UCR) code.” We interpreted that to mean a criminal offense that resulted in a jail booking and took place after the crime for which the person was COMPAS scored. ... **For most of our analysis, we defined recidivism as a new arrest within two years. **"

"\n",
"See [ProPublica article](https://www.propublica.org/article/how-we-analyzed-the-compas-recidivism-algorithm) for details. When evaluating performance of the prediction instrument, we consider **accuracy** and **parity** (or **balance**).\n",
"\n",
"- **High false-positives rates** Of those deemed likely to re-offend, in any crime category, only 61 percent were arrested for any subsequent crimes within two years. Only 20 percent of people predicted to commit violent crimes actually went on to do so.\n",
"\n",
"- **Racial skew in scores** Scores for white defendants were skewed toward lower-risk categories. Scores for black defendants were not -- a symptom of a potential problem.\n",
"\n",
"- **Racial skew in false-positive rates** 44.9% of African Americans are labeled high-risk but don't reoffend, compared to 23.5% of Caucasians.\n",
"\n",
"- **Racial skew in false-negative rates** 47.7% of Caucasians are labeled low-risk but do re-offend, compared to 28% of African Americans."

"What do we mean when we say that data is biased? Societal bias? Measurement bias?\n",

"### Be a technology skeptic!\n",

"African Americans have higher recidivism rates. [Recent results](https://arxiv.org/abs/1703.00056) show that when recidivism rates are different across sub-populations, then we cannot simultaneously equalize false-positive rates and false-negative rates! \n",
"\n",
"This is **not** a technical issue: it is not our definition that's flawed! Our society exhibits structural bias, which processes like those studies here reinforce.\n"
