# Psychopathia Machinalis

> Nell Watson and Ali Hessami's framework for understanding behavioural pathologies in advanced AI, with 74 patterns across nine diagnostic axes.

The framework uses psychiatric analogies to describe persistent behavioural dysfunctions. Its tools support investigation; they do not certify safety, consciousness, intent, or clinical status.
