Humans’ biggest advantage over other species is our ability to cooperate.

So well do we collaborate, Sloman and Fernbach argue, that we can hardly tell where our own understanding ends and others’ begins.

This assists our “illusion of explanatory depth”, as we believe that we know way more than we actually do.

And the “confirmation bias” is physical: we experience genuine pleasure—a rush of dopamine—when processing information that supports our beliefs.
