The holiday shopping season is upon us, and both Sony and Microsoft have just released brand-new, long-awaited video-game consoles, which means that kids will be clamoring for RPGs and first-person shooters even more than usual this year. The eternal question: Are you a bad parent if you let them have them?

A recent study came to a surprising conclusion: Maybe not! The study, published in March and written up in Games and Learning last week, was billed as showing rather conclusively that video games are not bad for kids. The Games and Learning headline: “Game Play Has No Negative Impact on Kids, UK Study Finds.” Here's the first paragraph:

A massive study of some 11,000 youngsters in Britain has found that playing video games, even as early as 5 years old, does not lead to later behavior problems.

Hooray! At last, definitive proof that kids can play all the video games they want and suffer no ill effects, right? Clearly that's a piece of news that people are itching to hear: Jane McGonigal, author of a best-selling book arguing that video games are good for us, tweeted her equally exuberant interpretation of the findings, and the response was overwhelming, with some 3,500 retweets.

Not to be a spoilsport, but before we throw in the dustbin a bunch of other studies that have found links between youth screen time and antisocial behavior, it's probably worth, you know, reading the actual paper. Which reveals that, in fact, the researchers did not track 11,000 kids for a decade. Rather, they drew their data from the broader, decade-long U.K. Millennium Cohort Study, but conducted their analysis only on a slice of data that looked at kids once at age 5 and then again at age 7.

I pointed this out to McGonigal, and she acknowledged the mistake, implying that she hadn't yet read the actual paper when she first tweeted about it. Presumably, neither did most of the 3,500 people who retweeted her — nor the authors of several other blog posts and articles that have picked up on Games and Learning's post, including MSN UK, Slashgear, Nintendo Life, and more. The worst offender so far is the video-game site IGN, which ran with the following absurd headline: “Games Definitely Don't Harm Kids, Says Huge Study.”

That is definitely not what the study said.

Rather, the researchers looked specifically at whether kids in the Millennium Cohort Study who played a lot of video games at age 5 had grown substantially worse in their behavior by age 7 compared to those who did not. The behavioral outcomes were based on the kids' mothers' assessments, and the researchers controlled for a wide array of factors, including income and family structure. Their goal: to see whether video games and/or television alone could be linked to negative changes in behavior over a two-year period from age 5 to age 7.

They did find some links between TV screen time and deteriorating behavior, but they did not find a link between video-game time and bad behavior (or ADHD, or emotional problems, or any of the other bugaboos that in the past have been ascribed to childhood screen exposure). Again, that doesn't mean the kids who played lots of video games at age 5 were all perfect angels at age 7, just that they weren't significantly worse than they already were at age 5, once you controlled for a number of other factors. As far as I can tell, the study did not look at all at the effects of video games or TV prior to age 5.

The researchers themselves make no such sweeping claims.

To be clear, I'm not arguing that video games are bad for kids. I'm just pointing out that this study does not prove what quite a lot of people seem to want it to. Sorry, parents. Science is trying to get you an answer, but for now, you're still on your own with this one.
