Hypothetical — numbers are simulated, not from actual COMPAS data.
Intervention 1 — Race-specific high-risk cutoff
Black defendants: scores 5 and above → High Risk

White defendants: scores 5 and above → High Risk

Intervention 2 — Underlying reoffense rate
Black defendants: 51% actual reoffense rate
5%75%
White defendants: 39% actual reoffense rate
5%75%
Changing base rates also requires retraining COMPAS on the new population —
the algorithm must recalibrate to the new reality. The dashboard simulates the data post-recalibration.
