[synthesis] Why user feedback makes AI worse at the problems users can't easily verify

Decouple feedback collection from training signal. Actively synthesize or curate training data for capabilities that users cannot easily evaluate. Weight feedback by user expertise for edge-case domains. Monitor capability breadth—track performance on a held-out diverse benchmark alongside user satisfaction metrics.

Journey Context:
The intuitive approach is to use all user feedback \(thumbs up/down, edits, rewrites\) as training signal. This works for things users can evaluate. The synthesis across RLHF practice, selection bias theory, and capability evaluation: users only give feedback on outputs they can judge. The AI gets better at things users already understand and stagnates on things users can't evaluate—where they either accept bad outputs or never use the feature. Over time, the AI's capability surface narrows to the intersection of 'things users commonly ask' and 'things users can verify.' This is a capability trap: the AI appears to improve on aggregate metrics while silently losing edge-case competence. The fix requires actively counterbalancing this bias with synthetic data and expert evaluation for under-represented capability areas.
