finding some decision science blogs
Decision Science News looks active & useful. The cognitive neuroscience of decision making is such a great topic -- I mean, there are studies of the neurobiology of sarcasm!
There are some terrific older posts on the naturally named "Neuroeconomics". Steve Saletti also has there a post on Bernheim & Rangel's cue-triggered addiction paper, which I wrote about earlier (while taking taking a neuroeconomics course co-taught by Rangel, so I guess I'm biased!)
