A new study from the University of Alabama found that women are a little more jealous than men, at least when it comes to social media.

Researchers asked 226 college-level men and women how they would feel after seeing a photo of their significant other with someone of the opposite sex on Facebook.  On a scale of one to nine, women admitted a jealousy level of six. Men, on the other hand, reported a jealousy level of four.

The results vary. A poll from iVillage, for example, found that husbands are significantly more distrusting than their wives. In their 2013 Married Sex survey, the site found that 34 percent of men have checked their wife's cellphone for evidence of cheating. Only 20 percent of wives have done the same. Maybe men are more jealous, or maybe they're just more willing to do something about it — either way, the answer's not that simple.

In a report for Scientific American, Christine Nicholson explains that when it comes to sex differences in jealousy, it's not so much about levels as it is types of jealousy:

"Studies from around the world have reported that men are more jealous of sexual infidelity than emotional infidelity," Nicholson explains. "And women are the opposite — they’re more jealous of emotional cheating than sexual cheating."

As with many behavioral traits, we have evolution to thank:

"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."

But a 2010 study in Psychological Science examined not only sex differences in jealousy but also personality differences. Researchers tested subjects to measure their attachment style in relationships.

They found that "dismissive women were four times more likely to report greater sexual jealousy than securely committed women," Nicholson explains of the study.

But for dismissive men, that number jumped to 50:

"…dismissive men were 50 times more likely to report sexual jealousy than securely committed men."

Based on these findings, it seems that dismissive women fare better than men when it comes to jealousy.

But overall, it's difficult to study our biological differences without also considering personality and even cultural impact. Individual history is also a hugely important factor — if you've been burned in the past, you're more susceptible to trust issues down the road.

What do you think — does jealousy vary between the sexes? Do men and women get jealous for different reasons?
