The political scientist Henry Farrell recently resurfaced a post of his about knowledge and the role of criticism. (It’s pegged to a debate over of whether we should or shouldn’t be less negative/critical online, which is to me the less interesting aspect.) It contains some excellent bits that dovetail with some of the posts I’ve done over the years on the social aspect of epistemology:
Reasoning has not evolved in the ways that we think it has – as a process of ratiocination that is intended independently to figure out the world. Instead, it has evolved as a social capacity – as a means to justify ourselves to others. We want something to be so, and we use our reasoning capacity to figure out plausible seeming reasons to convince others that it should be so. However (and this is the main topic of a more recent book by Hugo), together with our capacity to generate plausible sounding rationales, we have a decent capacity to detect when others are bullshitting us. In combination, these mean that we are more likely to be closer to the truth when we are trying to figure out why others may be wrong, than when we are trying to figure out why we ourselves are right…
…Our ability to see the motes in others’ eyes while ignoring the beams in our own can be put to good work, when we criticize others and force them to improve their arguments. There are strong benefits to collective institutions that underpin a cognitive division of labor.
This superficially looks to resemble the ‘overcoming bias’/’not wrong’ approaches to self-improvement that are popular on the Internet. But it ends up going in a very different direction: collective processes of improvement rather than individual efforts to remedy the irremediable. The ideal of the individual seeking to eliminate all sources of bias so that he (it is, usually, a he) can calmly consider everything from a neutral and dispassionate perspective is replaced by a Humean recognition that reason cannot readily be separated from the desires of the reasoner. We need negative criticisms from others, since they lead us to understand weaknesses in our arguments that we are incapable of coming at ourselves, unless they are pointed out to us.
This is why it’s useful to have an integrative mindset, or to triangulate the truth. We learn from others, sometimes by seeing an error in our reasoning and updating it–and other times by just granting the possibility that, though we can’t see any error in our own view, there’s still some chance that our critics are right.
