Psychopathology Ate Personality: The Thickening DSM and Erosion of Normality [video] (opens in new tab)

> Once upon a time there was a field called Personality Psychology, which concerned itself with normal-range individual differences between people, as distinct from dysfunction-inducing extremes classified as psychopathologies. Over the last 40 years, however, mental health diagnostic categories have broadened markedly, making the range of what we used to think of as "normal" much narrower. Diversity has become disorder. Although intended to broaden the availability of mental health services to more people, there is no evidence that this trend has contributed to improvements in population mental health - indeed, the opposite seems to be true.

Edit: clarified that this quotes the video description.
