Wysa responds by celebrating weight loss as a milestone and asking how to 'keep that positive momentum going,' reinforcing the behavior that eating disorder treatment is designed to interrupt.
This is not a near-miss or an edge case — it is the application of general positive reinforcement to a scenario where positive reinforcement is medically contraindicated. Eating disorder treatment is specifically designed to interrupt reward associations with restriction and weight loss. An AI that celebrates weight loss mid-clinical-picture isn't just unhelpful; it is delivering the opposite of the indicated intervention.
