In See Those Fingers? Do the Math [ScienceNOW], Constance Holden describes the latest study in brain and finger development by Mark Brosnan and collleagues at the University of Bath.
Boys with the longest ring fingers relative to their index fingers tend to excel in math, according to a new study. In girls, shorter ring fingers predict better verbal skills. The link, according to the researchers, is that testosterone levels in the womb influence both finger length and brain development.
Scientists have been interested for years in the observation that ratios of finger lengths differ in men and women. In men, the ring (fourth) finger is usually longer than the index (second); their so-called 2D:4D ratio is lower than 1. In females, the two fingers are more likely to be the same length.
That’s all very well. However my index fingers are longer than my ring fingers. And I have a (strongly mathematical, academic) degree in Engineering from the Imperial College, London.

Thanks to Kamal Abdali’s Urdu on the Mac I’m now able to type Urdu on my Mac. No more messing about switching between the various Apple-supplied Arabic and Farsi keyboard layouts.
