Aggregating Skeptical Thought

Evolution News?

I’m not one to be too politically correct but “It’s No Delusion” as the title to an article about the surprising results of research regarding schizophrenia seems a bit insensitive to me. If Scientific American keeps it up they might start making people think they are being laughed at or persecuted…. sorry.

Anyway, the research seems to support a natural selection for schizophrenia, sort of. Or perhaps schizophrenia is perhaps an unfortunate by-product. Here’s a good quote…

One [proposed theory] holds that schizophrenia is a “disorder of language” and that the illness is an unfortunate consequence of the development of human speech, expression and creativity. “Whenever you get strong selection, it’s like a big plus, and you can drag along a lot of minuses,” he says. “You can think of schizophrenics as paying the price of all the cognitive and language skills that humans have—they have too many of the alleles that taken individually…might have positive effect, but together they are bad.”
