Studies from around the world have reported that men are more
jealous of sexual infidelity than emotional infidelity. And
women are the opposite-they're more jealous of emotional cheating
than sexual cheating. Experts often lean on an evolutionary cause
for this gender difference: Men can never be sure they are the
baby-daddy and women are most concerned with securing a genuinely
loyal father to care for the children.
Well, authors of a recent study in Psychological Science question
the strength of the evolutionary just-so theory-realizing that
there are men who find emotional cheating far worse than sexual
cheating. The study reports that personality patterns, shaped by
one's relationship history, can have an impact on jealousy.
Over 400 participants took a survey to measure their jealousy type,
meaning which troubles them more: sexual or emotional fidelity.
Then they completed a test which specifically measures attachment
style in relationships (those styles include: secure, fearful,
preoccupied and dismissing.)
And they found that 65 percent of those who are autonomous and
tend to be dismissive about commitment reported greater stress about
sexual cheating than emotional cheating. And 77 percent of those
who are more securely attached and committed in relationships
found emotional betrayal to be worse than sexual duplicity.
Even within each sex the results were striking. Dismissive women
were four times more likely to report greater sexual jealousy
than securely committed women. And dismissive men were 50 times
more likely to report sexual jealousy than securely committed men.
So the authors warn: sex differences in jealousy are much more
nuanced than an evolutionary explanation might imply.
