A strange new study found the shorter a man’s index finger is in comparison to his ring finger, the more likely he is to be nice to a woman.
Research was conducted on 155 men and women, all of whom had their digit ratios calculated. Digit ratio is the length of the index finger to the length of the ring finger. Over a 20-day period, the subjects were asked to keep track of all social interactions that lasted more than five minutes, “classifying their own behavior toward others as either agreeable or quarrelsome,” Reports The Huffington Post.
When the study concluded, researchers found no link between digit ratio and women’s behavior. But men proved to be “less quarrelsome” with women than with other men if they had smaller ratios.
“When with women, men with smaller ratios were more likely to listen attentively, smile and laugh, compromise or compliment the other person,” the study’s co-author Debbie Moskowitz said in a McGill University press release.

A previous study, which similarly looked at digit ratios to indicate certain characteristics and behaviors, found that men with smaller ratios had more children than those with higher ratios.
“Our research suggests they have more harmonious relationships with women; these behaviors support the formation and maintenance of relationships with women,” Moskowitz said. “This might explain why they have more children on average.”
Digit ratio has been researched in depth in recent years, and has been frequently used to determine behavior and physical traits in a number of studies. It is believed that digit ratio is determined by “the amount of testosterone and other male hormones” that a fetus is exposed to in the womb.
