Check this out. According to a new Australian study, women appear to have the ability to decipher with some accuracy whether an unfamiliar male is cheating simply by looking at his face! What's funny is, men can't do the same when looking at strange women.

"More masculine-looking men were rated as more probable to be unfaithful and having a sexual history of being more unfaithful." They added, "We provide the first evidence that faithfulness judgments, based solely on facial appearance, have a kernel of truth."

Guys, on the other hand, seemed to have no clue. They tended to perceive attractive, feminine women to be unfaithful, when there was no evidence that they were, the scientists noted.
