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

Content: 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’. These shortcuts to interpreting and predicting our world often involve connecting dots and filling in gaps, making extrapolations and assumptions based on incomplete information and based on similarity to previously recognized patterns. In jumping to conclusions, our brains have a preference for familiar conclusions over unfamiliar ones. Thus, our brains are prone to error, sometimes seeing patterns where there are none. This may or may not be subsequently identified and corrected by error-detection mechanisms. It’s a trade-off between efficiency and accuracy.
