Creativity and affective illness: an objection

A good deal of attention has recently been given to two studies purportedly showing a connection between creativity and affective illness. In both cases, there have been inadequate (or absent) controls, biased selection procedures, single interviewer-experimenter bias, and, in one study, misrepresentative use of statistics. We have published contrary experimental results which, on a statistically significant level, differentiate creative thinking and creativity from psychopathological modes of response.
