[gotcha] Human-like AI language causes users to over-trust outputs and skip verification

Use tool-like, non-anthropomorphic language for factual tasks; disclose the system is AI; avoid personas in high-stakes outputs.

Journey Context:
Peter et al. \(2025\) in PNAS argue that LLMs are 'anthropomorphic conversational agents' whose fluent, empathetic style creates 'anthropomorphic seduction'—trust without warranted basis. Users cannot reliably distinguish LLM text from human text. When the tool says 'I've fixed the bug' it implies verification occurred; 'Applied patch to line 42' invites inspection. The uncanny valley here is not visual but social: the closer the prose feels to a helpful human, the less users treat it as probabilistic output.
