AI Use Reduces Perceived Warmth and Trust

A new study published in Computers in Human Behavior by Scott Claessens and colleagues finds that using AI to compose personal messages, like apologies, love letters or wedding vows, makes senders appear less warm, moral and authentic. The research shows these negative perceptions are task-dependent—AI assistance is tolerated for instrumental tasks but penalized in socio-relational contexts, implying people should avoid outsourcing sensitive personal communication to preserve trust.
