From his years of experience as a psychologist, Peterson is used to observing social dynamics. For example, he notes that higher on the social ladder, people are often less inclined to engage in humorous battles of wit than their working-class counterparts might enjoy doing. But perhaps the rarest form of conversation is the type that’s a shared search for truth, or philosophical discussion. This doesn’t necessarily mean a rarefied, academic discussion, but any conversation in which people put their egos second to solving a matter of shared concern.
