Few topics send the media into a panic like the idea of hookup culture on college campuses. But are college students actually having more sex than their parents did a generation ago? Research suggests the answer is no.

Lisa Wade, a sociologist at Occidental College, says something has changed, though: In today's hookup culture, developing an emotional attachment to a casual sex partner is one of the biggest breaches of social norms.

Researchers have long been confused by what seems like a paradox: many people in America vote against their economic self-interests. Whether it's the working class conservative who wants a tax cut for the wealthy, or a member of the liberal elite who fights for safety nets that raise his own taxes — we don't always act in the way that would help us the most.

If you've ever visited the palm-lined neighborhoods of Beverly Hills, you've probably noticed that the rich and famous aren't the only ones drawn there.

Stargazers also flock to this exclusive enclave, seeking a chance to peer into — and fantasize about — the lives of movie stars and film directors.

Call it adulation, adoration, idolization: we humans are fascinated by glamour and power.
