The Illusion of Understanding Everything

Most people believe they understand how everyday objects work, but they fail when asked to explain the details. You likely think you know how a zipper or toilet works, but you probably cannot explain the exact mechanics.

This cognitive bias is called the illusion of explanatory depth. We feel confident about our knowledge until we are forced to break down complex causal chains. It is not about knowing facts or stories, but about understanding how things truly function. This gap in understanding often drives political polarization, as people hold strong opinions on systems they cannot actually describe.
