Alison Gopnik reports in the Wall Street Journal: “Two large-scale surveys done in 2007 and 2013 in the Netherlands and Bermuda, involving thousands of adolescents, found that teenagers who engaged in more online communication also reported more and better friendships.”
That’s a heartening correlation to anyone who doesn’t want to have to worry about the consequences their kids’ technology use, but it isn’t causality. It should not be surprising that people who have more and closer friendships would communicate with those friends by whatever means their society and economy provides, and that “more online communication” would thus correlate with “more and better friendships.” I do wonder what, exactly, “more and better friendships means”; in particular I wonder if the researchers’ construction of that idea ultimately collapses into a definition of extraversion, but I’m not interested enough to dig up the original article. I’m more interested in Gopnik’s use of the study, which is to dismiss the worries of parents (or of anyone else) as mere nostalgia.
