A new research paper proposes a method to disentangle direct discrimination from structural inequality in AI-driven credit decisions. The study, which uses causal mediation analysis based on Pearl's framework, identifies interventional direct and indirect effects under a weaker assumption than previously required. An empirical evaluation on mortgage application data revealed that approximately 77% of racial disparities in credit denial were linked to structural inequalities, with the remaining 23% serving as a lower bound for direct discrimination. The researchers have also released an open-source Python package called CausalFair to implement their methodology. AI
