differential validity
What It Means
Differential validity occurs when an AI model or assessment tool performs accurately for one group of people but not for another group. The model might correctly predict job performance for one demographic but fail to do so for a different demographic, even when both groups have similar actual capabilities.
Why Chief AI Officers Care
This creates significant legal liability under employment discrimination laws and can expose companies to lawsuits and regulatory penalties. It also leads to poor business outcomes by systematically excluding qualified candidates from underrepresented groups, reducing talent pool diversity and potentially harming company performance and reputation.
Real-World Example
A hiring algorithm trained primarily on data from male software engineers might accurately predict job success for male candidates but consistently underestimate the potential of equally qualified female candidates, leading to discriminatory hiring practices even when women perform just as well in the actual roles.
Common Confusion
People often confuse differential validity with simple bias in outcomes, but differential validity specifically refers to the accuracy of predictions varying across groups, not just different approval rates between groups.
