Responding to the Prospect article that we recently linked to, "Philosophy's great experiment", Dwight Furrow has some thoughts up under the heading "Overselling Experimental Philosophy" -- and, to be clear, it is the the article that he is accusing of the overselling, not experimental philosophers themselves. I do think that this is something of a concern; so much of the coverage that experimental philosophy has received really has been rather unfortunately hyped up, in a way that is understandable given the way that part of media's being media is that it hypes things up. But this has led to some unhappy consequences (I'm sure many readers remember this fooferaw a couple of years back), and maybe goes some way towards explaining some of the strange attitudes that some philosophers have taken up in response to the body of work produced under the x-phi label.
And I find myself in agreement with a very large part of what Furrow says in his post, and I suspect that most of the x-phi community would agree with much of it as well. For example:
"X-phi is interesting because it might help philosophers do one part of their job. But it cannot solve philosophical problems." (I think that latter sentence is supposed to be read as meaning something like "X-phi cannot solve philosophical problems by itself.")
"The real problem with some contemporary philosophy is not the absence of scientific data but the use of odd and fanciful scenarios like the Trolley Problem to unearth how we reason."
"Experimental philosophy may help us determine what people believe and how they respond to various situations. Thus, it can act as a check against unreflectively assuming our intuitions are shared."
Nonetheless, despite these agreements, there are also some parts of his post that I think don't quite hit the mark. Furrow's post continues after that last quoted sentence as follows: "But brain scans can’t tell us much about why people think as they do, and tracking blood flow or electrical activity is not going to reveal very much about patterns of reasoning." But brain scans can, in fact, tell us very important things about why people think as they do! I take it that what's interesting about, e.g., Josh Greene's work in this regard is very much that it is providing some evidence for claims about what psychological factors are or are not in play when people make different sorts of moral judgments.
He continues: "Furthermore, questionnaires and observations of behavior are notoriously unreliable in explaining the motives behind our actions, and are hardly revolutionary." Well... is any part of philosophy really concerned with "explaining the motives behind our actions"? Have any experimental philosophers taken on such a question? And I don't see how armchair reflection is going to do a better job of offering such explanations. This may be a pitch for doing more and better x-phi -- or just plain more and better psychology -- but I don't see how it is much of a critique of the movement as such. (I'm also not sure what the point is about whether or not using surveys are "revolutionary". Seems to me it's clearly not at all revolutionary in psychology, which is a large part of why we're willing to use it ourselves; but it clearly does represent a nontrivial methodological shift in contemporary philosophy. What else is supposed to be at stake here?)
But, anyhow, that's just quibbling. I think the deeper disagreement is here, and I think it also points to a deeper promise on the part of x-phi for the philosophical project on the whole:
"Most importantly, X-phi could not begin to tell us how we ought to think about reality. It is rooted in what is, not what should be. It can be critical of philosopher’s pretensions but not of the beliefs it purports to describe. It will not be making philosophical discoveries."
Surely Furrow would be right if all he meant is that we will make few direct discoveries by doing x-phi -- for no one thinks that we're going to just learn whether compatibilism is true, or what normative moral theory is correct, or whether knowledge really is stakes-sensitive, just by looking at people's survey responses and brain scans. But that middle sentence of this last quote seems to aim for something stronger, and something that seems to me to indicate where things have gone off the rails here. Barring some particularly pure form of rationalism, most all of our thinking about "what should be" is itself thoroughly and ineliminably rooted in our thinking about "what is". Change your picture of what's going on descriptively in our minds and in our lives, and you will often change your picture of how our minds and lives should be directed. Just consider, for example, how many issues in the philosophy of mind have been transformed by shifts in the relevant sciences -- including, very much, our inquiries into the nature of rationality itself. Or, to pull an example from another literature I'm interested in, consider how enriched recent discussions in aesthetics has been by its engagement with descriptive psychology of the emotions (e.g., in Jenefer Robinson's Deeper than Reason). For exactly these reasons, I think we can expect that, pace Furrow, x-phi will indeed play a significant role in future philosophical discoveries.
