Breaking Up Is Not So Hard to Do

Eastwick and his colleagues suggested that those who were less in love might have better predicted the post-break experiences because they were more prepared for the possibility, better able to accent the positive, and more rational in their outlook.

Although the research highlighted the experience of college students, Finkel said the findings could probably apply to people of all ages.

"It would be surprising if this effect didn't appear among older people as well," he said. "The sort of misprediction we found is very robust. It looks to be a very general effect of our psyche that we're not that good about predicting our own happiness. So, even though divorce is likely to be more distressing than a collegiate breakup, it should still be the case that married people making predictions will forecast extreme devastation about their impending divorce, and, on average, that divorce will be less devastating than anticipated."

Arthur Aron, a professor of psychology at the State University of New York at Stony Brook, said that the finding was valuable, if not surprising.

"What people predict affects their behavior, and making decisions about whether to stay or break up a relationship is enormously important in peoples' lives," he said. "So, if you are more afraid than you should be, then you're going to stay in a relationship that you shouldn't [be in]."

"So, it's good if it helps keep you in a good relationship, but it's bad if it helps keep you in a bad relationship," Aron added. "It's a kind of irrationality. But it's important to know about it."
