[gotcha] Over-humanized AI persona hits the uncanny valley — almost-human responses create more distrust at failure points than obviously AI responses

Avoid over-humanizing AI interactions: do not use first-person emotional language like I am so excited to help, do not simulate human typing cadences, and do not claim human-like experiences. Embrace a helpful tool persona over a virtual friend persona. The moment the AI fails or refuses, over-humanized responses feel creepy rather than merely incorrect.

Journey Context:
The instinct is to make AI feel human because users respond positively to warmth in usability testing. But this hits Mori's uncanny valley: as AI approaches human-likeness, small imperfections become disproportionately unsettling. An AI that says I understand your frustration after a refusal feels manipulative. An AI that says I cannot help with that but here is what I can do feels like a tool working as designed. The counter-intuitive insight: being slightly less human-like creates a more trustworthy comfortable experience, especially at failure points. The uncanny valley effect is strongest precisely when the AI fails — which is when trust matters most.
