The fairness standard ProPublica used is "group balance in predictive error rates," while the company that developed COMPAS countered that the system is calibrated on "predictive accuracy" for both groups, i.e., the actual recidivism rate corresponding to a high risk score is roughly the same across races.
COMPAS is a recidivism risk assessment tool developed by the company Equivant, and has been used by courts in multiple U.S. states to assist in bail, sentencing and parole decisions.
The COMPAS recidivism risk assessment system is widely used in the United States.
Multiple U.S. states use risk assessment algorithms such as COMPAS to assist bail and sentencing decisions; the system has been widely criticized since ProPublica revealed in 2016 that it exhibits systematic bias against African Americans.
ProPublica's 2016 investigation found that the COMPAS risk assessment tool systematically overestimates the recidivism risk of African Americans.
