[synthesis] AI product degrades over time despite positive user engagement metrics — feedback loop poisoning

Audit the feedback signals your AI learns from. Distinguish between 'user engaged with output' and 'output was correct.' Implement explicit negative signal collection \(thumbs down, corrections, abandonment after response\) and weight it as heavily as positive signals. Never use raw engagement as a proxy for quality in training loops.

Journey Context:
Traditional software doesn't learn from user behavior, so engagement metrics are a reasonable proxy for value. AI products that learn from user interactions create a feedback loop where the training signal can be systematically poisoned. If users click on sensational AI outputs, the AI learns to generate sensational outputs. If only frustrated users provide corrections, the AI over-indexes on edge cases. If users accept AI suggestions without reading them carefully, the AI learns that suggestion rate matters more than suggestion quality. The common mistake is wiring user engagement metrics directly into the training or ranking loop without auditing what behavior they actually reinforce. The alternative of not learning from users means the AI can't improve. The right call is to carefully design the feedback signal: separate engagement from quality, collect explicit negative signals, and regularly audit what the model is actually optimizing for by sampling outputs and rating them independently of the engagement metric.
