Robert Brandom offers an influential and respected account of reasoning, which I find intuitive (see Brandom 2000 and other works). At the same time, a large body of psychological research suggests that reasoning–as he defines it–is rare.

That could be a valid conclusion. Starting with Socrates, philosophers who have proposed various accounts of reason have drawn the conclusion that most people don’t reason. Just for example, the great American pragmatist Charles Sanders Peirce defines reason as fearless experimentation and doubts that most people are open to it (Peirce 1877).

Brandom’s theory could support a similarly pessimistic conclusion. But that doesn’t sit well with me, because I believe that I observe many people reasoning. Instead, I suggest a modest tweak in his theory that would allow us to predict that reasoning is fairly common.

Brandom argues that any claim (any thought that can be expressed in a sentence) has both antecedents and consequences: “upstream” and “downstream” links “in a network of inferences.” To use my example, if you say, “It is morning,” you must have reasons for that claim (e.g., the alarm bell rang or the sun is low in the eastern sky) and you can draw inferences from it, such as, “It is time for breakfast.” In this respect, you are different from an app. that notifies you when it’s morning or a parrot that has been reliably trained to say “It is morning” at sunrise. You can answer the questions, “Why do you believe that?” and “What does that imply?” by offering additional sentences.

(By the way, an alarm clock app. cannot reason, but an artificial neural network might. As of 2019, Brandom considered it an open question whether computers will “participate as full–fledged members of our discursive communities or … form their own communities which would confer content” [Frápolli & Wischin 2019].)

Whenever we make a claim, we propose that others can also use it “as a premise in their reasoning.” That means that we implicitly promise to divulge our own reasons and implications. “Thus one essential aspect of this model of discursive practice is communication: the interpersonal, intra-content inheritance of entitlement to commitments.” In sum, “The game of giving and asking for reasons is an essentially social practice.” Reasoning in your own head is a special case, in which you basically simulate a discussion with real other people.

The challenge comes from a lot of psychological research that finds that beliefs are intuitive, in the specific sense that we don’t know why we think them. They just come to us. One seminal work is Nisbett and Wilson (1977), which has been cited nearly 18,000 times, often in studies that add empirical support to their view.

According to this theory, when you are asked why you believe what you just said, you make up a reason–better called a “rationalization”–for your intuition. Regardless of what you intuit, you can always come up with upstream and downstream connections that make it sound good. In that sense, you are not really reasoning, in Brandom’s sense. You are justifying yourself.

Indeed, the kinds of discussions that tend to be watched by spectators or recorded for posterity often reflect sequences of self-justifications rather than reasoning. I recently wrote about the scarcity of examples of real reasoning in transcripts and recordings of official meetings. As Martin Buber wrote in The Knowledge of Man (as pointed out to me by my friend Eric Gordon):

By far the greater part of what is called conversation among men would be more properly and precisely described as speechifying. In general, people do not really speak to one another, but each, although turned to the other, really speaks to a fictitious court of appeal where life consists of nothing but listening to him.

Some grounds for optimism come from Mercier and Sperber (2017). They argue that people are pretty good at assessing the inferences that other people make in discussions. Although we may invent rationalizations for what we have intuited, we can test other people’s rationalizations and decide whether they are persuasive.

Furthermore, our intuitions are not random or rooted only in fixed characteristics, such as demographic identities and personality. Our intuitions have been influenced by the previous conversations that we have heard and assessed. For instance, if we hold an invidious prejudice, it did not spring up automatically but resulted from our endorsing lots of prejudiced thoughts that other people linked together into webs of belief. And it is possible–although difficult and not common–for us to change our intuitions when we decide that some inferences are invalid. Forming and revising opinions requires attentive listening, critical but also generous.

The modest tweak I suggest in Brandom’s view involves how we understand the “game of giving and asking for reasons.” We might assume that the main player is the person who gives a reason: the speaker. The other parties are waiting for their turns to play. But I would reverse that model. Giving reasons is somewhat arbitrary and problematic. The main player is the one who listens and judges reasons. A speaker is basically waiting for a turn to do the most important task, which is listening.

This view also suggests some tolerance for events dominated by “speechifying.” To be sure, we should prize genuine conversations in which people jointly try to decide what is right, and in which one person’s reasons cause other people to change their minds. This kind of relationship is the heart of Buber’s thought, and I concur. But it is unreasonable to put accountable leaders on a public stage and expect them to have a genuine conversation. None of the incentives push them in that direction. They are pretty much bound to justify positions they already held. Although theirs is not a conversation that would satisfy Buber, it does have two important functions: it allows us to judge people with authority, and it gives us arguments that we can evaluate as we form our own views.

Again, if we focus on the listener rather than the speaker, we may see more value in an event that is mostly a series of speeches.
