The AI Diagnosis That Had No Disease Behind It

The bixonimania case matters not because AI hallucinated — that behavior was already documented — but because a researcher designed the hallucination as a repeatable experiment. Almira Osmanovic Thunström at the University of Gothenburg did not stumble onto this failure; she engineered it with precision, selecting a symptom cluster common enough to be plausible and a disease name implausible enough that no genuine clinical literature could exist. The AI systems had no way to fail gracefully. They filled the gap.
