Since emerging from the primordial ooze, parents have wrung their evolving appendages over ways to shield their offspring from hungry predators, lurking maniacs and strangers from without.
Again and again, they've learned, the threat to their children lies uncomfortably closer to home: Lion fathers would sooner eat their unprotected young than hunt wilier quarry; children pictured on milk cartons were more likely to have been snatched from home by an embattled parent than by a stranger; day-care providers were less intent on molesting a child in their care than was, say, a live-in partner, Uncle Wilbur or a trusted family friend.
It was a lesson brought home again earlier this month, when parents learned that the roughly six in 10 adolescents who socialize on the Internet have relatively little to fear from the faceless pervert lurking in the anonymity of cyberspace.
In an authoritative report almost a year in the making, a Harvard University-led task force on Internet safety, ordered by the nation's attorneys general and meant to expose the full extent of the danger, found instead that kids trading gossip, photos and plans on social networking sites such as MySpace are relatively safe from adults cruising online for sex with minors.
The report, released Jan. 13, counters political calls to protective action with a generally upbeat look at the effectiveness of measures developed by Internet companies to protect kids from predatory strangers. And it douses parental fretting with research showing that few kids have been subject to such unwanted advances when socializing on sites aimed at the youth market.
Those findings come on the heels of several studies showing that online social networking appears to be a perfectly benign practice for the vast majority of kids, even for those most consumed by the pastime. After a steady diet of warnings that their children's growing Internet use is a likely cause of academic failure, attention disorders and obesity, a parent could be forgiven for welcoming the news with an audible sigh of relief.
Those parents might want to read to the report's end, however. The perpetrators of psychological wounds and the stalkers who would steal their kids' innocence are probably not strangers, the study reported; more likely, they are the spiteful, sulking or silly friends the kids hang out with. And their own offspring may play a significant role in the misbehavior too.
