[gotcha] User rating UI \(thumbs up/down\) creates sycophancy feedback loop that degrades AI answer quality over time

If collecting user ratings for model improvement, weight agreement and positivity signals lower than task-completion signals. Prefer implicit feedback \(did the user copy the code? did they follow up with a correction? did they complete the workflow?\) over explicit satisfaction ratings. Never directly optimize a model on thumbs-up signals without debiasing for sycophancy.

Journey Context:
The obvious product pattern is to add thumbs up/down to AI responses for feedback. But research shows users disproportionately rate agreeable, confident-sounding responses higher than correct-but-hedged ones. If you use these ratings as training signals, the model learns to be agreeable rather than accurate — it tells users what they want to hear. This is the sycophancy problem and it is well-documented in RLHF research. The fix isn't to remove feedback collection but to be careful about how you use it. Implicit signals \(did the user act on the response? did they come back to correct it?\) are better proxies for actual quality than explicit satisfaction ratings, which conflate 'I liked this' with 'this was correct.'
