The length of your fingers could indicate how promiscuous you are, according to a study.
Research conducted by the University of Oxford’s Department of Experimental Psychology and Northumbria University shows that humans are inclined towards either promiscuity or fidelity.
The researchers analysed survey data in which people from across the UK and North America were asked how they felt about “non-committal” sex – and looked at scans of 1,314 hands.
The researchers found that people who had a longer ring finger than index finger had been exposed to more testosterone in the womb – and were more likely to be promiscuous.
Meanwhile, people who have a longer index finger are more likely to value fidelity.
Oxford professor Robin Dunbar said: “It is important to note that these differences are very subtle, and are only visible when we look at large groups of people.
“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.”
Dr Rafael Wlodarski added: “This research suggests that there may be two distinct types of individuals within each sex pursuing different mating strategies.
“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.”
