Check out the new Midwest Studies in Philosophy volume on "Philosophy and the Empirical." You may be able to access the articles here or here. There are a lot of interesting articles, and several articles on free will and moral responsibility, including ones by Shaun Nichols, Dana Nelkin, Thomas Nadelhoffer & Adam Feltz, and yours truly (with co-authors Justin Coates and Trevor Kvaran). Our article (which I link below in case you don't have access) includes the largest survey yet of intuitions about FW and MR (over 1000 subjects, 8 scenarios, 20 experimental questions), the results of which seem to support my claim that determinism per se is not intuitively threatening to FW and MR unless it is presented in a way that suggests reductive mechanism (but there are some other intruiguing results summarized in the Table and briefly canvassed in the appendix). At some point we hope to set up a webpage with more info on the studies and a link to the surveys so we can collect data from philosophers.
All the best, Eddy
