Is being stubborn a part of human nature? Is this a irremediable flaw of humanity?
Cognitive dissonance is the psychological effect of holding two contradicting thoughts in mind at one time. It’s uncomfortable. It presents a mental stress and is not something that people generally do happily or willingly. We all search for ‘consonance’ that proves our expectations and reality are aligned.
So most people read/watch things that support their current model of reality.
