When a baby is born, the obstetrician or midwife announces “It’s a boy” or “It’s a girl.” As toddlers, children learn to classify everyone as either boy or girl. When our firstborn was very young, we overheard her talking to herself as she grappled with the concept:
Let’s see… I’m a girl, and Kimberly [her baby sister] is a girl, and Mommy’s a girl… but Daddy’s not a girl… He’s a boy. [Pause followed by exasperated sigh] Cause he doesn’t know any better!
As with most things in science, the concept of boy versus girl is more complicated than it appears at first glance. It’s not a simple dichotomy. We humans like to classify everything into neat pigeonholes, but Nature’s inventiveness outsmarts us at every step.
I’ll be the first to admit that the quality of TV programming, especially network programs, leaves much to be desired. Critics of television have blamed TV for everything from violence to obesity. Now studies have shown that teens who watch sexy programs are more likely to become sexually active and to get pregnant. I’m not so sure that these studies really show what TV critics think they show. My local newspaper was equally skeptical.
We frequently criticize media coverage of scientific issues, so for once I’d like to offers kudos to the Tacoma News Tribune for publishing this editorial:
TV and teen pregnancy: A lot else is also at work
THE NEWS TRIBUNE

For parents, the headline was ominous: “Study links TV, teen pregnancy.”
The article that appeared in The News Tribune Tuesday reported on a Rand Corp. study published in this month’s issue of Pediatrics magazine. Researchers say they found a link between higher teen pregnancy rates and watching television shows that have lots of sexual dialogue and behavior – ones like “Sex in the City, “That ‘70s Show” and “Friends.”
The implication is that if teens watch such racy programming, they’re more likely to become sexually active themselves – and therefore more at risk of getting pregnant or impregnating someone else.
But couldn’t something else also be at work here? (more…)
