Women experience more emotional pain following a breakup, but they also more fully recover, according to new research from Binghamton University.
Researchers from Binghamton University and University College London asked 5,705 participants in 96 countries to rate the emotional and physical pain of a breakup on a scale of one (none) to 10 (unbearable). They found that women tend to be more negatively affected by breakups, reporting higher levels of both physical and emotional pain. Women averaged 6.84 in terms of emotional anguish versus 6.58 in men. In terms of physical pain, women averaged 4.21 versus men's 3.75. While breakups hit women the hardest emotionally and physically, women tend to recover more fully and come out emotionally stronger. Men, on the other hand, never full recover -- they simply move on.
According to Craig Morris, research associate at Binghamton University and lead author on the study, the differences boil down to biology. Women have more to lose by dating the wrong person.
"Put simply, women are evolved to invest far more in a relationship than a man," Morris said. "A brief romantic encounter could lead to nine months of pregnancy followed by many years of lactation for an ancestral woman, while the man may have 'left the scene' literally minutes after the encounter, with no further biological investment. It is this 'risk' of higher biological investment that, over evolutionary time, has made women choosier about selecting a high-quality mate. Hence, the loss of a relationship with a high-quality mate 'hurts' more for a woman."
Conversely, as men have evolved to compete for the romantic attention of women, the loss of a high-quality mate for a man may not "hurt" as much at first, Morris said.
"The man will likely feel the loss deeply and for a very long period of time as it 'sinks in' that he must 'start competing' all over again to replace what he has lost -- or worse still, come to the realization that the loss is irreplaceable," he said.
Morris said that breakups are important because most of us will experience an average of three by age 30, with at least one affecting us strongly enough that it substantially decreases our quality of life for weeks or months.
"People lose jobs, students withdraw from classes, and individuals can initiate extremely self-destructive behavior patterns following a breakup," he said. "With better understanding of this emotional and physical response to a breakup -- Post Relationship Grief -- we can perhaps develop a way to mitigate its effects in already high-risk individuals."
The study, "Quantitative Sex Differences in Response to the Dissolution of a Romantic Relationship," was published in Evolutionary Behavioral Sciences on July 31.
