Maybe It's Time to Put Women in Charge of Wall Street

It seems old evolutionary pressures are causing males to make bad decisions once again:

A recent study by the Human Behavior Evolution Society, as reported in LiveScience, found that higher levels of testosterone correlate with riskier financial behavior. Men with more testosterone make riskier investments than those with lower levels.

To be specific, men with 33 percent more testosterone than average fellows invested 10 percent more of their dough. Men with manly facial features invested 6 percent more than their round-faced peers.

Higher risk can pay off. Another study shows that traders make more dough on days when their testosterone levels are at their highest -- when they take bigger gambles.

So hey, why not put the ladies in charge? They certainly couldn't do any worse.
