Stupid is as stupid does ...

Judging sex difference from points of masculine vs feminine 'lights' (The Way S/he Moves, by Rachel Zelkowitz, Science NOW Daily News, 9 September 2008).

Researchers often study these kinds of signals using something called a point-light figure, a collection of dots arranged in a human form. The figure is supposed to convey minimal information, but simple manipulations--broadening the dots on the shoulder region or narrowing dots that represent the waist--can make figures seem more masculine or more feminine.

There seems to be a profusion of 'science' studies making amazingly silly assumptions about behavioral sex differences from remarkably biased testing that seems to satisfy male assumptions about female thoughts, behaviors and motivations.
