Gaydar research

AAAS Science Mag reports:

Talk about "gaydar." In just a fraction of a second, people can accurately judge the sexual orientation of other individuals by glancing at their faces, according to new research. The finding builds on the growing theory that the subconscious mind detects and probably guides much more of human behavior than is realized. ...

Ambady and colleague Nicholas Rule, both at Tufts University in Medford, Massachusetts, wondered about sexual orientation. They showed men and women photos of 90 faces belonging to homosexual men and heterosexual men for intervals ranging from 33 milliseconds to 10 seconds. When given 100 milliseconds or more to view a face, participants correctly identified sexual orientation nearly 70% of the time.

I am not sure this study proves anything. Maybe 20 out of the 90 had haircuts that match stereotypes.
