A powerful explanation of how beliefs are formed, and what little resemblance they have to reality.
Your beliefs form the fundamental model that you use to navigate the world, to think about things, to decide what to do and what to avoid, like a map. We form a lot of these beliefs by middle childhood.
And since you’re the one who built the map, it’s natural to believe that it corresponds to the territory that you are navigating. After all, most of the time, your map gets you where you want to go. So much so that when the map doesn’t get you where you want to go, the first thing you question is not the map but reality.
