Next time your significant other catches you in bed with someone else, try this defense:

“Don’t take it personally, babe. Promiscuity is built into my genes. I was born this way!”

Good luck with that. But the argument actually might be true. A recent study found that both men and women are naturally inclined toward either frequent, casual encounters or long-term, stable ones. Which are you? If you don’t already know, take a look at one of your hands. A long ring finger compared to the index finger indicates testosterone had a big effect on you in the womb, regardless of your gender. Guess which category that puts you in?

The study’s research team, a collaboration of Britain’s Oxford and Northumbria universities, analyzed and cross-referenced data from two different academic surveys: one on the sexual attitudes of 600 men and women (each of the subjects took the detailed, intense “sociosexual orientation inventory” questionnaire), the other on the finger lengths (yes, really) of 1,300 men and women. The results, it seems, were conclusive.

Received wisdom long has had it that we’re all more or less the same when it comes to sexual behavior, with the exceptions (those few who are either really promiscuous or asexual) proving the rule. But this new study suggests instead that we all are either naturally promiscuous or faithful, and that we “are specialized for these roles.”
