Turns out the answer is: not much. We understand reasoning to be an individual act. This is, in many cases, wrong. “The central flaw in the concept of reason that animated the eighteenth-century Enlightenment is that it is entirely individualistic,” writes philosopher Joseph Heath.12 But decades of research has proven that “reason is both decentralized and dispersed across multiple individuals. It is not possible to be rational all by yourself; rationality is inherently a collective project.”
