It seems that the shorter a guy's index finger is compared to his ring finger, the more likely he is to be nice to women, or so says a strange new study according to HuffPo. This means that men whose index fingers and ring fingers are close in length, or whose index fingers are longer than their ring fingers, may be more likely to be antagonistic to women.
Dr. Debbie Moskowitz, a psychology professor at McGill University in Montreal and the study's lead author, said in a written statement,
"When with women, men with smaller ratios [of index to ring finger] were more likely to listen attentively, smile and laugh, compromise or compliment the other person."
Moskowitz and her colleagues measured the fingers of 155 men and women, and for each calculated their digit ratio--that is, the length of the index finger to the length of the ring finger. Then, over the course of 20 days, the study participants kept track of every social interaction they had that lasted over five minutes, classifying their own behavior toward others as either agreeable or quarrelsome.
The researchers found no link between behavior and digit ratio in women. But men with small digit ratios reported engaging in one-third more agreeable behaviors and one-third fewer quarrelsome behaviors. What's more, guys with small ratios tended to be less quarrelsome with women than with other men.
"These behaviors support the formation and maintenance of relationships with women. This might explain why they have more children on average."
The study adds to a large body of research on digit ratio and its relationship with behavior and physical traits. A study published earlier this month showed that men and women with small digit ratios are more likely to be promiscuous. A 2011 study linked small digit ratios in men with longer penises.
