Ideology is the codification of these belief systems into shared frameworks that structure how a community perceives reality and distributes value and blame. Understanding the psychology of belief requires understanding not just what people believe but why belief itself is so compelling, and what conditions allow the mind to hold its convictions with both commitment and genuine openness.
