Sorry, what does this have to do with rationality and/or philosophy? Please don't just post links, there are many sites that are better suited for that, e.g. Digg and Reddit.
However, do you think that Lesswrong should have a journal club section (perhaps for social science papers)? I think that would be pretty cool actually. Especially considering the number of scientists reading LW. :)
I disagree:
