OK. Look Carefully at Your Fingers...

A very interesting item.

“Coates examined the digit ratio of 44 male “high frequency” traders in London who buy and sell securities, sometimes in amounts greater than $1 billion, but hold their positions for minutes, sometimes only seconds. He found that traders with a longer ring finger than index finger made more money.

“We were on the trading floor taking samples for another experiment, and I read an article about digit ratio and sports,” says Coates. “I didn’t put too much stock in the measure, but we thought, ‘Why not look at fingers?’ We were shocked by the results.”

Exposure to high levels of testosterone before birth appears to make men more sensitive to the hormone as adults. In addition to playing a role in sexual functioning, testosterone has been associated with aggressive behavior and enhanced risk taking, and has been shown to predict performance in certain competitive sports.

Coates’ findings are consistent with a Harvard study of testosterone and financial risk taking that appeared in the November 2008 issue of Evolution and Human Behavior. Using an investment game, the Harvard researchers found that higher testosterone levels correlate with financial risk-taking behavior.

Actually, forget YOUR hand and start checking the hands of your friendly local Bank loan officer.

And you thought that reading blogs was just a bunch of opinion hooey BS, eh?
