The premise
Adverse credit decisions require specific reasons by law; AI explainability is regulatory necessity, not just nice-to-have.
What AI does well here
- Implement explainability methods that produce specific, factual adverse-action reasons
- Validate that reasons match what the model actually weighted
- Maintain the audit trail of every adverse decision and its reasoning
- Test reasons for understandability by typical applicants (not regulator-only language)
What AI cannot do
- Substitute generic reason codes for actual model explanation
- Make AI black-boxes compliant with reason-required regulations
- Eliminate the legal requirement to provide reasons
