Josh Knobe (UNC) and I are doing a study on causal judgment, and one of the things we want to test is whether the judgments of philosophers are different from those of naive subjects. Thus we are hoping to attract a number of philosophers to take our on-line study. I am wondering if you would be willing to post a brief advertisement on your web page, which reaches a lot of philosophers. I think that this is something that a lot of philosophers would find interesting.  The study takes about ten minutes, and anyone can participate by going to the website.
