Truly intellectually humble individuals systematically lower their confidence in a belief when confronted with evidence that they lack a mechanical understanding of it.

We often fall victim to a strange trick of the mind. We mistake familiarity for true understanding. When asked how a simple zipper or a toilet works, we think we know. But when pressed for details, we falter. Research shows that intellectually humble people quickly recognize this gap. They immediately moderate their confidence when shown they cannot explain the underlying machinery. It is a vital self-correcting mechanism.
