[gotcha] Overly polished or enthusiastic AI tone triggers distrust and the uncanny valley effect

Tone down AI responses: remove exclamation marks, reduce hedging language \('I'd be happy to help\!'\), avoid unsolicited enthusiasm. Match the formality of the user's input. For professional tools, default to concise, neutral tone. Add subtle brevity that signals 'this is a tool, not a person.' Test with users specifically for the 'does this feel manipulative?' reaction.

Journey Context:
AI systems are tuned to be helpful and friendly, which often manifests as excessive enthusiasm, over-qualification, and chatty tone. This backfires: users report feeling 'sold to' or manipulated. The AI uncanny valley in consumer products is not about almost-looking-human — it is about the tone being human-like but without the contextual awareness that makes human communication feel genuine. A human would not say 'Great question\! I'd love to help you with that\!' in a professional setting. The AI does, and it feels off. The counter-intuitive part: making the AI less friendly and more robotic actually increases trust because it sets accurate expectations. Users trust a tool that acts like a tool more than a tool that acts like an overly eager assistant. The tradeoff: for consumer products, some warmth is expected. The key is matching context — a creative writing assistant can be warm; a code review tool should be direct.
