Finger length tied to aggresiveness
A new study by sychologists at the University of Alberta suggest that the length of a man's fingers can predict how inclined he is to physically aggressive behavior. The same does not hold true for women. From the press release about the study, published in the scientific journal Biological Psychology:
(Professor Peter) Hurd said that it has been known for more than a century that the length of the index finger relative to the ring finger differs between men and women. More recently, researchers have found a direct correlation between finger lengths and the amount of testosterone that a fetus is exposed to in the womb. The shorter the index finger relative to the ring finger, the higher the amount of prenatal testosterone, and--as Hurd and (grad student Allison) Bailey have now shown--the more likely he will be physically aggressive throughout his life.Link
