That I find it unsettling that many people I know and respect disagree with me about the epistemic significance of disagreement is perhaps unsurprising. There are, after all, psychological studies that suggest that we are highly disposed to being greatly influenced by the views of others, and I have no reason to think that I am exceptional with respect to this particular issue. It is, of course, a different question whether the fact that many others disagree with my thesis provides a good reason for me to doubt that thesis. And my answer to this question, as might be expected, is ‘No’: because I accept the general thesis that known disagreement is not a good reason for skepticism, I do not, in particular, regard the fact that people disagree with me about this general thesis as a reason for being skeptical of it. Although I tend to find it somewhat unsettling that many disagree with my view, I am inclined to regard this psychological tendency as one that I would lack if I were more rational than I in fact am. In contrast to my psychological ambivalence, my considered, reflective judgment is that the fact that many people disagree with me about the thesis that disagreement is not a good reason for skepticism is not itself a good reason to be skeptical of the thesis that disagreement is not a good reason for skepticism.
