Ever wondered what makes a person more interested in a short-term fling versus a long-term commitment? A new study carried out by Oxford University and Northumbria University reveals it is the length of your index finger.
The results, published in the Journal Biology Letters, evaluated North American and British attitudes towards “non-committal sex” and looked at photocopies of British people’s right hands. The scientists discovered that the shorter the index finger is to the ring finger increases the likelihood an individual was exposed to higher levels of testosterone in the womb. Higher levels of testosterone have been previously associated with higher levels of promiscuity.
Coupling finger length with respondents’ answers to attitudes on casual sex showed that humans are split into two distinct groups, one that values sexual freedom and the other, sexual fidelity. The results showed no differences across gender.
Dr Wlodarski explains, “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.”
So a person’s likeliness to commit is not based upon gender, but rather your fingers.
