The paradigm has shifted. Dating is dated. Hooking up is here to stay.

(For those over 30 years old: hooking up is a casual sexual encounter with no expectation of future emotional commitment. Think of it as a one-night stand with someone you know.)

According to a report released this spring by Child Trends, a Washington research group, there are now more high school seniors saying that they never date than seniors who say that they date frequently. Apparently, it’s all about the hookup.

When I first heard about hooking up years ago, I figured that it was a fad that would soon fizzle. I was wrong. It seems to be becoming the norm.

I should point out that just because more young people seem to be hooking up instead of dating doesn’t mean that they’re having more sex (they’ve been having less, according to the Centers for Disease Control and Prevention) or having sex with strangers (they’re more likely to hook up with a friend, according to a 2006 paper in the Journal of Adolescent Research).
