"The panelists each threw out their theories for the decline of college dating: Christakis thinks it's because college students these days are too focused on resume-building and career preparation. They're indoctrinated into the cult of extracurricular activities in middle and high school, and the involvement obsession continues throughout college almost as if by inertia. "It's 'I'm secretary of this' and 'I'm director of that,'" she said. "And even they admit that a lot of it is kind of bogus." Rachel Greenwald, an author and dating coach, thinks it's because most college "relationships" now occur within the context of a brief sexual encounter, or "hookup," as the youth say. "Romance," she said, "has gone the way of cursive handwriting." A recent study by the American Psychological Association found that between 60 and 80 percent of North American college students have had a hookup, even though 63 percent of college men and 83 percent of college women said they would prefer a traditional relationship. "In gearing themselves up for sex, they're draining themselves emotionally," Greenwald said. "They are in training to ... discard, to ignore, to swallow their emotions so they can participate in the anxiety-provoking but common dynamic which is the hookup culture." Lori Gottlieb, an Atlantic contributor, author, and psychologist, thinks it's because Millenials have been so coddled by their parents and teachers that they are now unable to accept others' opinions and realities. Which makes it hard when, in a relationship, your reality is that you will go to the farmer's market and make a healthy salad together, and your partner's reality is Starcraft."
