[gotcha] AI-generated content in the uncanny valley — almost-human output creates more distrust than clearly artificial output

Avoid the middle ground between clearly AI and genuinely human-quality output. Either: \(1\) lean into structured, clearly AI-labeled presentation \(bullet points, labeled sections, 'AI-generated' badges\), or \(2\) invest heavily in quality to cross the threshold to genuinely indistinguishable. Specifically: strip sycophantic filler \('Great question\!', 'I'd be happy to help\!'\) from system prompts, offer templates users customize rather than ready-to-send AI text for human contexts, label AI content clearly, and tune prompts to remove agreeable hedging that mimics human social signaling without the substance.

Journey Context:
There's an uncanny valley for AI output: content that's 90% human-like is trusted less than content that's clearly machine-generated. A structured AI summary with bullet points and a 'Generated by AI' label is trusted more than a paragraph that sounds almost human but has slightly wrong tone, slightly off phrasing, or that unsettling AI 'voice'. Users feel manipulated by content that attempts to pass as human. The counter-intuitive insight: making AI output 'more human' can decrease trust if it doesn't fully cross the threshold to 'actually human'. The worst place is the middle — conversational filler and faux warmth that falls flat. Either be clearly a tool \(trusted as a tool\) or be good enough to pass \(trusted as human\).
