David Menconi looks at an intellectual movement – called, simply enough, "experimental philosophy" – that tries to perform them:
These scholars use the tools of social science—they devise questionnaires, go out and conduct surveys, gather data—and then try to figure out what philosophical truths they reveal. At times, experimental philosophy looks no different than social psychology. (It is perhaps telling that Knobe has office space in both the philosophy and psychology departments at Yale.) It's a lot more likely than conventional philosophy to be a collaborative effort, too. When experimental philosophers disagree over something, Knobe says, the default response is for them to try to work together.
Naturally, there's a blog about it.
