- Among defendants who did NOT reoffend, what did ProPublica find about Black defendants compared with white defendants?
- They were less likely to be scored at all
- They had identical risk labels
- They were nearly twice as likely to be labeled higher risk
- They were more likely to be labeled lower risk
- What was the core of Northpointe's defense of COMPAS?
- At each score level, Black and white defendants reoffended at similar rates (calibration)
- The tool used race to correct for historical bias
- ProPublica had analyzed the wrong county
- The tool was never used in any court
- Under what condition does the impossibility result say calibration and equal error rates cannot all hold?
- When the model uses more than 100 features
- When the dataset has fewer than 10,000 people
- When race is included as an input
- When groups have different base rates and the predictor is not perfect
- What did the Wisconsin Supreme Court hold in State v. Loomis?
- COMPAS is unconstitutional and banned from courts
- Judges may consider COMPAS, but it cannot be the deciding factor, and written cautions are required
- COMPAS scores must decide the length of sentences
- Defendants must be shown the full source code
- Is race an input to COMPAS?
- Yes, it is the most heavily weighted factor
- Yes, but only for defendants in Florida
- No; it uses criminal history and questionnaire answers
- No; it uses only a defendant's age
- What did the 2018 study by Julia Dressel and Hany Farid find?
- Untrained online volunteers predicted rearrest about as accurately as COMPAS
- COMPAS was more than 90 percent accurate
- Judges ignored COMPAS scores entirely
- COMPAS had no racial disparities in Broward County
- Using FPR = (p/(1-p)) x ((1-PPV)/PPV) x (1-FNR), if PPV and FNR are equal across groups but group A has a higher base rate p, what happens to group A's false positive rate?
- It must be lower
- It must be zero
- It is unaffected by p
- It must be higher
- Why does leaving race out of a risk model not guarantee unbiased outcomes?
- Courts require race to be included
- Correlated inputs such as prior arrests can carry historical policing patterns
- Models cannot run without demographic data
- Leaving race out always makes the model less accurate for every group
