The length of a man's ring finger may predict his success as a financial trader, the AP reports. Researchers at the University of Cambridge in England report that men with longer ring fingers, compared to their index fingers, tended to be more successful in the frantic high-frequency trading in the London financial district. Indeed, the impact of biology on success was about equal to years of experience at the job.
The researchers measured the right hands of 44 male stock traders, and over 20 months, those with longer ring fingers compared to their index fingers made 11 times more money than those with the shortest ring fingers. Looking only at experienced traders, the long-ring-finger folks earned 5 times more than those with short ring fingers. The same ring-to-index finger ratio has previously been associated with success in competitive sports. (Read more scientific study stories.)
