Finger Length Predicts Speed, Aggression, Smarts, Motivation

Previous research has shown:
* Finger length can predict the likelihood of aggression in men (but not women).
* Kids with longer ring fingers are likely to have higher SAT math scores than literacy or verbal scores, while children whose index fingers are longer are more likely to do better at reading and writing, or verbal, rather than the math tests.
* A 2006 study in the journal BMJ linked a certain finger ratio to women's athletic prowess and also linked the differences to hormones in the womb.
* People whose ring finger is longer than their index finger are at higher risk of osteoarthritis, according to a study last year in the journal Arthritis and Rheumatism.
You can finger other body parts as behavior predictors, too.
A 2004 study in the American Journal of Human Biology found that the farther certain paired body parts were from symmetry — one ear or foot bigger than the other, for example — the more likely a person would show signs of aggression when provoked.
"Stressors during pregnancy [such as poor health, alcohol use or smoking] may lead to asymmetrical body parts," explained researcher Zeynep Benderlioglu of Ohio State University. "The same stressors will also affect development of the central nervous system, which involves impulse control and aggression." While asymmetry doesn't cause aggression, she said, the two things "seem to be correlated to similar factors during pregnancy."....
Boys with ring fingers longer than their index fingers run faster, a new study finds.
Finger-length ratios have been related to a host of things good and bad, from fertility and disease vulnerability to test scores and personality traits. In fact, you'll need the digits on both hands, regardless of their length, to count all the correlations that have been made.
Researchers say exposure to testosterone in the womb is behind the speedy kids and their finger-length ratios. The scientists studied 241 boys aged 10 to 17 at a talent-spotting competition in Qatar. Those with longer ring fingers were faster at every stage of a 50-meter sprint race, according to an article in The Telegraph.
"The advantage they had was soon apparent after the start of the sprint and remained steady thereafter," said John Manning, a researcher at Southampton University who led the study.
