Algorithmic Bias

This is a series of bar charts depicting the results of the COMPAS algorithm in the US—which assigns risk scores based on how likely a defendant will recidivate—against the actual two-year outcome. Each bar chart depicts the same data, but from a different perspective. Click or tap on any of the chips above the chart to change perspective. Notice how the algorithm appears to be fair with regard to ethnicity in some perspectives but not others.
