I mentioned the first rumblings of this story back in the spring, but I think it’s worth mentioning again because we can be pretty sure that politico types are going to get a lot of mileage out of it over the next week or so: new neurological research suggests there are fundamental differences in the brain functions of people with conservative and liberal attitudes. My money says we’ll hear both sides of the political divide using these results as grist for their mill … which leads me to conclude it’s so self-evident as to be largely useless. Of course, your mileage may vary!
