So there's this blog called Bad Science, consisting mostly of the articles that medical doctor Ben Goldacre writes for the Guardian. It's about pseudoscience, medicine and medical research. And also awesome.
The recent article was a wonderful bit of emotional whiplash, and is about as subject I think is useful to keep in mind when contemplating research. But really, I recommend reading everything.

Also, the second-most-recent article, which should appeal to LW-types:

One of the things that seems to be emphasized in what I've read is how difficult it is for Westerners to understand what is going on inside the Party, but the reviews of that sound interesting (especially the talk http://www.brookings.edu/~/media/Files/events/2008/0415_china/20080415_china.pdf ), so I'll put it on my list.
