Aaron Beck developed cognitive therapy in the early 1960s, with its core mechanism being teaching patients to evaluate evidence impartially rather than selectively reinforcing negative outlooks.

Summary

This anchors the historical origin of cognitive therapy and its central working principle: the patient is trained to weigh all evidence the way a fair juror would, rather than only collecting data that confirms their worst fears. It matters because it frames mental distress as a problem of biased reasoning rather than a chemical or character flaw, which shapes how the system models the mechanism behind therapeutic change.
