Reported psychological harms from chatbots
From the early edition, with research available through September 12, 2026 (UTC).
Clinician raters identified descriptions consistent with delusional beliefs in 102 of 185 harm reports; 50 of those described chatbot validation. Reported consequences included isolation, relationship breakdown, and hospital admission.
Why it matters for leaders
Review how student-facing systems respond when conversations involve distress or implausible beliefs. Require clear routes to trained human support and a process for reporting concerning interactions.
The evidence
The dataset contains 95 first-hand and 90 second-hand accounts submitted to a support organization. Median reported age was 35; researchers independently coded deidentified accounts.
Who was studied
Predominantly adult reports: school safeguarding context
What the evidence cannot tell us
Reports were self-selected, retrospective, and unverified. These proportions describe a harm-reporting sample, not all chatbot users. The study establishes neither causation nor risk rates for children.
