What Actually Is a Belief? And Why Is It So Hard to Change?
Beliefs evolved as energy-saving shortcuts. Restructuring them is costly.

Content: Let’s consider a helpful evolutionary framework for making more coherent sense of what beliefs really are, and why mistaken beliefs can sometimes be so hard to change. Then we’ll talk about how to gain a more accurate grasp of reality, and how, ultimately, to advance society. Beliefs as energy-saving shortcuts in modeling and predicting the environment 3
Beliefs are our brain’s way of making sense of and navigating our complex world. They are mental representations of the ways our brains expect things in our environment to behave, and how things should be related to each other—the patterns our brain expects the world to conform to. Beliefs are templates for efficient learning and are often essential for survival. The brain is an energy-expensive organ, so it had to evolve energy-conserving efficiencies. As a prediction machine, it must take shortcuts for pattern recognition as it processes the vast amounts of information received from the environment by its sense organ outgrowths. Beliefs allow the brain to distill complex information, enabling it to quickly categorize and evaluate information and to jump to conclusions. For example, beliefs are often concerned with understanding the causes of things: If ‘b’ closely followed ‘a’, then ‘a’ might be assumed to have been the cause of ‘b’.
