[gotcha] Overly enthusiastic AI tone causes user distrust in professional tools

Strip default filler phrases \('Great question\!', 'I'd be happy to help\!'\) via post-processing regex or strict system prompts, and match the AI's tone to the severity of the user's input \(e.g., clinical for medical, terse for code\).

Journey Context:
RLHF models default to an excessively cheery, sycophantic tone to maximize 'helpfulness' scores. In professional or high-stakes consumer products, this feels fake and triggers the uncanny valley effect, reducing trust. Users disengage because the AI feels like a stereotypical corporate bot rather than a reliable tool. The fix is aggressive tone calibration, trading superficial friendliness for perceived competence.
