Headscarf Study
Interesting study cited on The Monkey Cage website about the effect headscarves have on people's perception of women. The effects are dramatic and a bit unsettling.
In this study, subjects were randomly assigned to view a picture of a woman or a picture of this same woman wearing a headscarf in the style of some Islamic women. Here are the two pictures:
Here is a link to the results of the study (scroll down a bit).
UPDATE: CNN has a piece on Iraqi women now being forced to wear headscarves in Basra - something that did not happen under Sadham's brutal, but secular, rule. Often the penalty is death.
