"My genes made me do it."
Believe it or not, you'll have scientific backing. This study suggests a link between promiscuity and DNA. An excerpt:
A particular version of a dopamine receptor gene called DRD4 is linked to people's tendency toward both infidelity and uncommitted one-night stands, the researchers reported Nov. 30 in the online open-access journal PloS One.
The same gene has already been linked to alcoholism and gambling addiction, as well as less destructive thrills like a love of horror films. One study linked the gene to an openness to new social situations, which in turn correlated with political liberalism.
Regardless of the study's disclaimers, I fear cheating will eventually be regarded not as an individual lapse in judgment, but rather as a pre-determined force over which daters have no control.
Weigh in: Do discussions of a genetic predisposition toward infidelity affect your dating outlook?
