In the NYT science section yesterday, John Tierney had a good article about X-Phi and free will. Shaun Nichols and Joshua Knobe studied what happens when people start to question whether there's free will. They cheat more and don't work as hard. Ouch.
More X-Phi: this is a very interesting study on whether the intuitions of ethicists are particularly firm and stable, compared to everyone else's. Bad news: they aren't.
Scott Atran on The Moral Landscape. Very long...looks interesting.
