(Telegraph) The longer the ring finger compared to the rest of his hand – particularly the index finger – then the more chance he is the kind of go-getter who makes big money.
University researchers found testosterone levels affect the ratio in finger lengths in both men and women – yet it is only men who personality traits are also directly linked to these levels. Where men have a low ratio – ring to index finger – the higher testosterone, making them alpha males. These men were found to be bigger risk takers but with a stronger will to win whether it is playing the stock market or playing squash, said the study’s findings.
Academics at Canada’s Concordia University measured finger lengths and personality differences among 415 men and women for the journal Personality and Individual Differences. The alpha males, whose ring fingers were longer than their index finger, were greater risk takers in all areas of their lives. These are often the kind of men women go for, said researcher Eric Stenstrom, because they are seen as fit, rich and assertive he added. He said: “Our findings show an association between high testosterone and risk-taking among males in three domains: recreational, social and financial.
“Since women tend to be attracted to men who are fit, assertive and rich, men are apt to take risks with sports, people and money to be attractive to potential mates. “What’s interesting is this tendency is influenced by testosterone exposure – more testosterone in the womb can lead to more risks in the rink, the bar and the trading floor in later in life.” Women, however, show no difference in behaviour no matter what kind of finger lengths they have, said the study.
Professor Gad Saad, lead researcher, said: “In women, the two fingers are usually almost equal in length, as measured from the crease nearest the palm to the fingertip. In men, the ring finger tends to be much longer than the index. “Previous studies have linked high testosterone levels with risky behaviour and financial success. “We investigated the relationship between prenatal testosterone and various risk proclivities. Our findings show an association between high testosterone and risk-taking among males in three domains – recreational, social and financial.”
