To head off any parallel worries within experimental philosophy, Christian Mott has put together the webpage Replications in Experimental Philosophy. Try taking a quick look. You can scroll down to see the studies that are most important to your own work, then check to see whether anyone has tried to replicate those studies and, if so, how the results came out.
One thing that has been especially striking to me about work in this area so far has been the really positive and generous attitude that experimental philosophers have taken to the issue of replication. In some cases, experimental philosophers have found that particular effects fail to replicate, but in all the cases that I know of, they have approached the issue in a spirit of genuine scientific curiosity -- not trying to 'get' the philosopher whose work they are testing, but truly engaged in an attempt to get to the bottom of the relevant intellectual issues. (I have gotten a chance to experience this at first hand: one of my own effects seems not to be replicating, but the philosophers who failed to replicate it appear to be motivated entirely by a spirit of disinterested truth-seeking.) As our work on this stuff continues, let's hope we can hold on to our reputation for virtue!
Anyway, Christian would love to hear about further replications, whether published or unpublished. So if you know of any replications that aren't already up on his page, just write them out in the comments section of this post (using the same format he has been using so far), and he will go ahead and add them in. Feel free also to include any thoughts you might have about what the results of the replication might be telling us about any larger issues.
