The ostritch approach to science really gets on my nerves. The "I don't like that hypothesis, so I will disparage it" attitude reminds me of a line in, I think, The Hitchhiker's Guide to the Galaxy that goes something like "If you can't see it, it can't see you." (I could be wrong on the source, it's been a while since I read those books). Both statements are equally dangerous regardless of how politically correct.

Don't look now, but Larry Summers might have been right after all.
