The development of hands of a boy foretell whether he will be nice to women when he grows into adulthood, says a study tracing baby boy’s exposure since the days in his mother’s womb.
“It is fascinating to see that moderate variations of hormones before birth can actually influence adult behavior in a selective way,” said the study’s co-author Simon Young, a psychiatry professor at McGill University.
The formula footed was simple. The smaller the ratio between a man’s index finger and his ring finger, the nicer his atitude towards women, said researchers.
It means the finger length is determined by the levels of male hormones like testosterone, a baby is exposed to while he was in his mother’s womb. If he is exposed to lower male hormone levels, then he will turn kinder towards women.
“When with women, men with smaller ratios were more likely to listen attentively, smile and laugh, compromise, or compliment the other person,” said lead author Debbie Moskowitz, from the McGill University. “Our research suggests they have more harmonious relationships with women; these behaviors support the formation and maintenance of relationships with women. This might explain why they have more children on average.”
Before arriving at their findings, researchers studied 155 participants for over 20 days, evaluating their social interactions, levels of acceptance, and frequency of disagreements.
The researchers found that men with smaller differences between their ring and index fingers’ length were a third more agreeable and a third less quarrelsome compared to those who have longer index fingers than the ring fingers. Another side angle discovered was that they tend to have more children too.
This is not the first time finger lenth was linked to sexuality or kindness to women. Researchers from Northumbria and Oxford Universities in the past found that the shorter the index finger to the ring finger, the more testosterone they were exposed to in the womb. Otherwise, longer index finger than the ring finger or more or less equal in length means the man is likely to be engaged in more sexual partners.
The McGill University study on the findings was published in the journal Personality and Individual Differences
