But to start, Matt Richel discusses the study on the Bits NY Times blog, and points out that "among the crucial questions that the researchers were not able to answer is whether the heavy use of media was the cause for the relative unhappiness or whether girls who are less happy to begin with are drawn to heavy use of media, in effect retreating to a virtual world" (fifth paragraph into the post).
I'm still thinking about these ideas, but these works brought up how important it is to study and ask questions about the ways life works for youth (and everyone, actually). Technology use and non-use are big parts of life. And they (the study and post, and the posts I mention below that led me to them) remind me of how important it is to think about the ways we can make life better for ourselves and the people we care about.
(Rob Beschizza's post on BoingBoing led me to Brian Lam's post Happiness Takes (A Little) Magic, which led me to Richel's article. These posts together got me thinking about life and taking a break from the daily grind of tech use. Which makes me think of Thoreau. Interestingly, that thought happened before I got to Lam's references to Thoreau - good to know someone else goes the same direction with that).
