Finger ratio may suggest straying behavior

Many anecdotes have educated us to the knowledge that Homo sapiens do not neatly fall into either promiscuity or faithfulness category when it comes to intimacy.

We all know of couples who remain faithful, but also of men who stray frequently – that is not to say that even once is acceptable.

Researchers at University of Oxford claim they have found the statistical differences between the two tendencies.

“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,” said Rafael Wlodarski, an experimental psychologist and study co-author.

One of the sources used was the data obtained from 1,314 British men and women – an investigation based on something known as the “2D:4D” ratio, suggesting that the length of one’s ring finger indicates the level of the hormone testosterone to which one was exposed in the womb. And the longer your ring finger is, compared to your index finger, the higher the likely concentrations of fetus testosterone.

In turn this ration has been linked to a higher statistical likelihood of promiscuity.

The data showed that 57 percent of men were more likely to be promiscuous and 43 percent faithful. For women, 47 percent fell within the “stray” category and 53 per cent in “stay”.

The 2D:4D study, based on a purely physiological characteristic, showed higher “stray” numbers for both men and women – 62 percent and 50 percent respectively.

“Human behaviour is influenced by many factors, such as the environment and life experience,” said Robin Dunbar, a professor at the Oxford unit that did the research. “What happens in the womb might have only have a very minor effect on something as complex as sexual relationships.”
