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:

I'm pretty sure I found Overcoming Bias through one of the links on the Bad Science blog. Either that or the Mind Hacks blog, which I...uh...found out about through Bad Science.
He's not been maintaining the miniblog links for the past month or so because he's been on tour with Uncaged Monkeys (a very awesome live show about science), but they're usually about the sorts of things I imagine most LW readers would appreciate.
I've wondered how I found Overcoming Bias. I've determined the approximate date I found it from a facebook post I made, but I don't remember how I found it. It could have been from Bad Science.
