I want to expound on the implication of causation in the example. Should we automatically conclude that the person's diagnosis of schizophrenia was the cause of the behavior? The person also had diagnoses of depression, vertigo, hypertension and heart disease. Is it possible that one--or a combination of--these diagnoses was the cause of the person's behavior? Is it possible that the person was extremely depressed? Is it possible that the person lost balance and simply fell against the woman? Is it possible that the person had a stroke or heart attack and fell against the woman? Maybe the woman was not pushed.

My point is that we should not automatically conclude that the person's diagnosis of schizophrenia was the cause of the behavior.
