[synthesis] Why does incorporating user feedback make the AI worse for some user segments

Before incorporating user feedback into training, audit the feedback distribution across user segments. Weight feedback by segment representation, not volume. Explicitly track which error types generate feedback \(users correct factual errors but not tone or style issues\) and supplement with targeted evaluation on under-represented feedback types. Never fine-tune solely on organic feedback without stratified evaluation.

Journey Context:
In traditional software, bug reports are uniformly useful — a crash is a crash regardless of who reports it. In AI products, user feedback is heavily skewed in three ways that interact: \(1\) power users provide disproportionate feedback, causing the model to optimize for advanced use cases at the expense of beginners; \(2\) users are more likely to correct factual errors than style, tone, or omission issues, so RLHF signals are biased toward factual accuracy over other quality dimensions; \(3\) users who experience the worst outputs often just leave rather than providing feedback, creating survivorship bias. The synthesis: incorporating user feedback without correcting for these skews doesn't just fail to improve the model — it actively steers it away from the needs of the users who need the most help, creating a model that gets better for power users and worse for newcomers simultaneously.
