The Stunning Thing That Researchers Say Finger Length Can Show About Promiscuity and FaithfulnessNew research out of the U.K. claims that both men and women tend to fall into two categories: those with a propensity toward promiscuity or those who favor faithfulness. Psychologists at Northumbria University and Oxford University examined an online questionnaire analyzing sexual habits of U.S. and U.K. individuals between the ages of 18 and 63, while also exploring photos of the right hands of 1,314 British individuals to explore the 2D:4D ratio — the notion that the ring finger’s length is tied to testosterone levels in the womb, according to AFP. A longer ring finger means more prenatal exposure to testosterone, with researchers claiming that past analysis has shown that people with index and ring fingers that are the same length are more likely to be faithful — and those with a longer ring finger could be more likely to cheat. In this particular study, the questionnaire provided information about the attitudes of individuals when it comes to “noncommittal” sex, while the 2D:4D information allowed researchers to explore past claims about how the length of the ring finger could be tied to monogamy.  “From previous work, the researchers already knew that the higher levels of [fetal] testosterone can go together with greater sexual promiscuity as an adult,” Oxford University reported. “While not predictive of individual behaviour, the length of the ring finger versus the index finger can help identify the group of people who are more likely to be promiscuous.” Exploring the answers on sexual attitudes, researchers found that people fall into one of two groups: one that showed a higher value for monogamy and fidelity and another that was comprised of people “more likely to be promiscuous,” which was true for both men and women.
