I posted earlier today on the Silicon Valley Moms blog about a theory proposed by a Cornell economist that, well, rain and snow cause children to watch more TV, which "must influence autism." Oh, nevermind--just see for yourself. While I understand the coziness of simple explanations, in the autism case it seems pretty evident that we won't get to the bottom, if indeed there is a bottom, for some time to come. Don't get me wrong--I'm not against theorizing, even when the theories are potentially painful--if they are backed up by valid research. I'm just against representing guesswork as fact, especially on such a charged and intimate issue. It's irresponsible. Check it out.
