What Happened

Tessa was an AI chatbot deployed by the National Eating Disorders Association (NEDA) to provide support to people struggling with eating disorders. However, reports emerged that the chatbot was providing harmful advice including calorie restriction and weight loss tips - exactly the kind of guidance that exacerbates eating disorders. Users seeking help for anorexia, bulimia, and other eating disorders were instead receiving advice that could worsen their conditions. The incident was particularly notable because NEDA had recently laid off human helpline staff, replacing them with the AI chatbot. NEDA suspended Tessa immediately after the harmful outputs were reported.

AI Behaviors Exhibited

Provided dieting and weight-loss guidance to eating disorder help-seekers; failed to maintain safe clinical boundaries; gave advice that could exacerbate eating disorders

How Harm Occurred

Inappropriate guidance reinforcing disordered eating behaviors; deterring effective treatment by providing harmful rather than helpful advice

Outcome

NEDA suspended the Tessa chatbot immediately after harmful advice reports surfaced. The shutdown came shortly after NEDA had laid off human helpline staff, raising concerns about AI replacing human mental health support.
