n the late 1960s, hospital-based researchers in Massachusetts conducted a study asking mental health clinicians to describe what they considered the characteristics of a psychologically healthy man, a psychologically healthy woman, and a psychologically healthy adult “sex unspecified”. The clinicians had to do this by rating each on a set of bipolar attributes (eg, “very passive” vs “very active”, or “tactful” vs “blunt”) that they thought were sex-stereotypical.
