People whose ring and index fingers are same length are more likely to be faithful , A new Study claims


Are you promiscuous or faithful? Measure your index finger to find out! They say that men are from Mars and women are from Venus, Humans fall into two groups, one more inclined to be promiscuous and the other more inclined to be faithful.

The results, published in the journal Biology Letters, are from a joint study carried out by Professor
Robin Dunbar of Oxford University’s Department of Experimental Psychology and Professor John
Manning of Northumbria University

The new study, titled ‘Stay or Stray? Evidence for Alternative Mating Strategy
Phenotypes in Both Men and Women’ suggests that in fact there are two distinct sub-populations of
humans: one that is more interested in short-term flings and another that prefers to form long-term commitments.
The researchers analysed the answers of 575 North American and British people about their
attitudes and desires towards “non-committal” sex.
Some of the respondents were more likely to be promiscuous, and others more likely to value sexual fidelity. However, the divide was not along gender lines.


The study also looked at photocopies of the right hand from 1,314 British men and women and
measured the length of the index (second) finger and the ring (fourth) finger.
The shorter the index finger in relation to the ring finger (the 2D:4D ratio), the higher the levels of testosterone that person is likely to have been exposed to while developing in the womb, and the
greater their sexual promiscuity will be as an adult.
This is true for both men and women. One group had a ring finger which was much longer
than the index finger, suggesting that they may be more promiscuous.
The other group had fingers which similar in length, meaning they are more likely to seek long-term
relationships. Again, the split was not along gender lines.

“We observed what appears to be a cluster of males and a cluster of females who are more inclined to ‘stay’, with a separate cluster of males and females being more inclined to ‘stray’, when it comes to sexual relationships.”
Professor Dunbar added that the differences are “subtle” and “only visible when we look at large
groups of people”.
He said: “Human behaviour is influenced by many factors, such as the environment and life
experience, and what happens in the womb might only have a modest effect on something as complex as sexual relationships.”
