Apparently there’s a correlation between the ratio of the length of your ring finger to your index finger, and how well you perform on the math compared to the critical reading section on the SAT.
A quick look at the lengths of children’s index and ring fingers can be used to predict how well students will perform on SATs, new research claims.
Kids with longer ring fingers compared to index fingers are likely to have higher math scores than literacy or verbal scores on the college entrance exam, while children with the reverse finger-length ratio are likely to have higher reading and writing, or verbal, scores versus math scores.
Scientists have known that different levels of the hormone testosterone and estrogen in the womb account for the different finger lengths, which are a reflection of areas of the brain that are more highly developed than others, said psychologist Mark Brosnan of the University of Bath, who led the study.
Of course, the same measure of finger length also correlates with the level of aggression in men and various other cognitive functions, since it’s really just used as a measure of how much testosterone versus estrogen you were exposed to in the womb. Still, kinda cool, right?
