How rational is our rationality?

Here is an excerpt:

As I mentioned earlier, I think that the point of the study of rationality, and of normative epistemology more generally, is to help us figure out how to inquire, and the aim of inquiry, I believe, is to get at the truth. This means that there had better be a close connection between what we conclude about what’s rational to believe, and what we expect to be true. But it turns out to be very tricky to say what the nature of this connection is! For example, we know that sometimes evidence can mislead us, and so rational beliefs can be false. This means that there’s no guarantee that rational beliefs will be true. The goal of the paper is to get clear about why, and to what extent, it nonetheless makes sense to expect that rational beliefs will be more accurate than irrational ones. One reason this should be of interest to non-philosophers is that if it turns out that there isn’t some close connection between rationality and truth, then we should be much less critical of people with irrational beliefs. They may reasonably say: “Sure, my belief is irrational – but I care about the truth, and since my irrational belief is true, I won’t abandon it!” It seems like there’s something wrong with this stance, but to justify why it’s wrong, we need to get clear on the connection between a judgment about a belief’s rationality and a judgment about its truth. The account I give is difficult to summarize in just a few sentences, but I can say this much: what we say about the connection between what’s rational and what’s true will depend on whether we think it’s rational to doubt our own rationality. If it can be rational to doubt our own rationality (which I think is plausible), then the connection between rationality and truth is, in a sense, surprisingly tenuous.
