Can Humans Detect AI? Mining Textual Signals of AI-Assisted Writing Under Varying Scrutiny Conditions

The Takeaway
People can successfully identify AI-assisted writing even when the authors were specifically warned to hide their tracks. Computational linguistic metrics show no detectable difference between these texts and human ones. The human brain picks up on subtle patterns and vibes that current state-of-the-art detection software cannot quantify. This suggests that the human ear for language is still far more sensitive than any mathematical model. We are intuitively aware of an artificial presence in writing even when we cannot explain why it feels wrong.
From the abstract
This study asks whether the threat of AI detection changes how people write with AI, and whether other people can tell the difference. In a two-phase controlled experiment, 21 participants wrote opinion pieces on remote work using an AI chatbot. Half were randomly warned that their submission would be scanned by an AI detection tool. The other half received no warning. Both groups had access to the same chatbot. In Phase 2, 251 independent judges evaluated 1,999 paired comparisons, each time cho
