[gotcha] Non-deterministic AI retries create addictive slot-machine UX instead of converging on better answers

When implementing retry/regenerate: \(a\) show the previous response alongside the new one for comparison, \(b\) limit consecutive retries \(e.g. 3 regenerations before suggesting the user rephrase\), \(c\) vary the system prompt or parameters on retry rather than re-sending identical requests, \(d\) surface retry count — 'You have tried 3 times. Consider rephrasing your question for better results.'

Journey Context:
Because LLM outputs are non-deterministic, each retry can produce a completely different answer. This creates a slot-machine dynamic: the user keeps pulling the lever hoping for a better result. Unlike traditional software where 'try again' might help with transient errors, AI retries give different answers that may all be wrong — just differently wrong. The user cannot tell if they are converging on a better answer or just spinning. This is especially problematic in creative or generative tasks where 'better' is subjective. The psychological pattern mirrors variable-ratio reinforcement, which is the most addictive reward schedule. The fix is to make retries productive rather than random: show history so users can compare, suggest rephrasing so they change the input, and make it clear that retrying the same prompt identically is unlikely to help. Some products implement a 'variation' UI that shows 2–3 options side by side, which is healthier UX than sequential single-answer retry.
