Who Needs Intuitions? Two Experimentalist Critiques

I've just finished what I hope is nearly the final set of revisions on a paper on intuitions, philosophical methodology, and experimental philosophy. This is my oldest paper that I haven't given up on; it derives from material that was in my Ph.D. thesis in 2008. If anybody wants to read it, comments are very welcome. (I'm due to submit it by the end of the month, so comments are especially helpful if they're before then.)

Who Needs Intuitions? Two Experimentalist Critiques
Abstract. A number of philosophers have recently suggested that the role of intuitions in the epistemology of armchair philosophy has been exaggerated. This suggestion is rehearsed and endorsed. Many of these philosophers take this observation to undermine the experimentalist critiques of armchair philosophical methodology that have arisen in recent years. The dialectical situation here, I suggest, is more complex than it appears. I will argue that the so-called ‘experimentalist critique’ really comprises two very different kinds of challenges to armchair methodology. One, which I call the ‘defeater critique’, does not depend on any particular view about the philosophical significance of intuitions, even though its proponents often emphasize the language of intuition. The other, however, which I call the ‘arbitrariness critique’—prominent in earlier experimentalist work, especially that of Stephen Stich—does depend on a central role for intuitions. I survey some attempts to motivate this critique without reliance on assumptions about the centrality of intuitions, and find them unconvincing. So rejecting the centrality of intuitions is a sufficient response to the arbitrariness critique, even though it is orthogonal to the defeater critique.

False Intuition and Justification

Suppose somebody has a false intuition about an a priori matter. Is she justified in believing its content? Many plausible answers, of course, will begin with "it depends...". On what does it depend?

Ernie Sosa thinks that among the things upon which it depends is whether the false intuition derives from "some avoidably defective way"; such errors constitute "faults, individual flaws, or defects." (I think Sosa means these two quoted bits to be approximately equivalent, or at any rate, to apply together in the relevant cases.) Sosa thinks this is what is going on when somebody follows her strong inclination to affirm the consequent, inferring from q and (if p, q) to p. By contrast, "the false intuitions involved in deep paradoxes are not so clearly faults, individual flaws, or defects. For example, it may be that they derive from our basic make-up, shared among humans generally, a make-up that serves us well in an environment such as ours on the surface of our planet."

So Sosa's line is that false intuitions do not justify when they derive from faults, flaws, and defects, but do justify when they derive from our basic make-up and are generally shared among humans. I'm suspicious that this distinction will hold up to scrutiny. I think there may be an equivocation on the relevant kinds of 'faults,' 'flaws,' and 'defects' going on. In one sense, of course, one is flawed by virtue of being incorrect; beliefs are supposed to be true, so if one goes wrong, that constitutes some sort of defect. This, of course, cannot be what Sosa has in mind. Instead, he seems to be imagining flaws as deviations from some sort of imperfect but generally effective strategy for getting around in the world. This is, perhaps, the more ordinary sense of a defect. My computer, even when it is working properly, will occasionally crash; a tendency to crash constitutes a defect only when it is not working properly. And maybe there is a good reason why humans ought to have tendencies to accept, for instance, naive set theory.

The problem for this line is that there is also plausibly sound reason for humans to have tendencies to commit more obvious errors, like affirming the consequent. Given the environments we face, having a tendency to affirm the consequent will help us to recognize patterns and confirm hypotheses; inductive reasoning generally looks a bit like affirming the consequent. Similarly with other standard errors; they derive from heuristics that are generally helpful.

So we face a dilemma for upholding Sosa's distinction. Do we say that these errors — these false judgments arising from generally good heuristics — constitute defects or not? If not, then they are relevantly like Sosa thinks the intuitive premises involved in deep paradoxes are. If so, what makes them so, and why should they not apply also to the cases of the paradoxes?

Consider three people. First, the possible über-rational being who looks at me the way the fallacious gambler now looks to me. She describes us both as defective; as failing to live up to the standards of rationality. She can see that I am not tempted by one particular error (the gambler's fallacy) — but also that I regularly commit another (fallacy X), and have some attraction to a third (naive set theory). Second, myself: I think of the fallacious gambler as defective, but of myself and my peers, I think our attraction to naive set theory as nondefective; my more ignorant peers who have not studied philosophy, I even consider justified. (We will suppose I have Ernie's views.) Third, the gambler himself, who accepts his characteristic fallacy and naive set theory alike, and sees no defect in any of us. He considers himself justified in both cases.

All parties agree that the gambler is wrong; he proceeds in a defective way inconsistent with intuitive justification. But Ernie thinks I'm importantly different from him. Ernie thinks that I am not defective, but merely have some tendencies to affirm falsehoods that derive from my general human nature. Our rational superior, presumably, thinks of me as defective in just the same way as the gambler, but to a lesser degree. Does Ernie give any reason we should think her wrong about this?

Concepts and Survey Results

I'm thinking about a point that Ernie Sosa has made in response to survey-based experimental philosophy challenges. As we all know, some critics have argued that certain experimental results challenge traditional armchair philosophy. In particular, for example, Weinberg, Nichols, and Stich found that there seemed to be a systematic divergence of epistemic intuitions depending upon the ethnic background of the subjects studied: students of East Asian descent were more likely than students of European descent to, for instance, describe Gettier cases as cases of knowledge.

Here's a line that Ernie has pressed a few times now:
And the disagreement may now perhaps be explained in a way that casts no doubt on intuition as a source of epistemic justification or even knowledge. Why not explain the disagreement as merely verbal? Why not say that across the divide we find somewhat different concepts picked out by terminology that is either ambiguous or at least contextually divergent? On the EA side, the more valuable status that a belief might attain is one that necessarily involves communitarian factors of one or another sort, factors that are absent or minimized in the status picked out by Ws as necessary for “knowledge.” If there is such divergence in meaning as we cross the relevant divides, then once again we fail to have disagreement on the very same propositions. In saying that the subject does not know, the EAs are saying something about lack of some relevant communitarian status. In saying that the subject does know, the Ws are not denying that; they are simply focusing on a different status, one that they regard as desirable even if it does not meet the high communitarian requirements important to the EAs. So again we avoid any real disagreement on the very same propositions. The proposition affirmed by the EAs as intuitively true is not the very same as the proposition denied by the Ws as intuitively false.

(That's quoted from his contribution to the recent Stich and His Critics volume.)

As I'd understand it, the core suggestion here is this: maybe there's no real disagreement here; some group of subjects say that such and such 'is a case of knowledge,' while philosophers and other subjects say that such and such is not a case of knowledge, and there's no genuine disagreement, because the former subjects don't mean knowledge by 'knowledge'.

So here's my question. (One question, anyway. I have a few more.) What does any of this have to do with concepts? As I understand it, it's a question about meaning and reference: what does the word 'knowledge' refer to in a given subject's mouth? One can run a little detour through concepts if one wants: word meanings are concepts; the concepts are different; so the word is ambiguous. But what, if anything, does this 'conceptual ascent' contribute? I rather suspect that it does more to distract than to help. Steve Stich's response to Sosa emphasizes concepts in a way that looks to me largely irrelevant:
There is a vast literature on concepts in philosophy and in psychology (Margolis and Laurence 1999; Murphy 2002; Machery forthcoming), and the question of how to individuate concepts is one of the most hotly debated issues in that literature. While it is widely agreed that for two concept tokens to be of the same type they must have the same content, there is a wide diversity of views on what is required for this condition to be met. On some theories, the sort of covert ambiguity that Sosa is betting on can be expected to be fairly common, while on others covert ambiguity is much harder to generate. For Fodor, for example, the fact that an East Asian pays more attention to communitarian factors while a Westerner emphasizes individualistic factors in applying the term ‘knowledge’ would be no reason at all to think that the concepts linked to their use of the term ‘knowledge’ have different contents (Fodor 1998).

But Fodor's theory of concepts is not a theory of word meanings. What bearing does it have on whether there might be an Asian-American idiolect in which 'knowledge' means something other than knowledge? (I do mean this as a serious question; I'm less fluent in Fodor than I'd like.)

To my mind, the sort of view that Ernie needs to be worrying about is not Fodor's but Burge's. More on that in a future post, I think. For now, just this question: is anything usefully gained by thinking about Sosa's suggestion here in terms of concepts?

Sosa on Virtues, Perception, and Intuition

Sosa on Virtues, Perception, and Intuition. Version of 19 January, 2009.
I critically evaluate Ernest Sosa's (2007) contrast between intuitive justification and perceptual justification. I defend a competence-based approach to intuitive justification that is continuous with epistemic justification generally.
