A shortcut to understanding belief formation: We adopt beliefs from the people we love and trust. Like tastes, beliefs are something people possess that aren't governed by logic. They persist even without social pressure and remain unchanged when their underlying reasons are disproven.

Beliefs persevere even without any social pressure. … The belief will not change when the reasons are defeated. The causality is reversed. People believe the reasons because they believe in the conclusion … We believe what the people we love and trust believe. This is not a conscious decision to conform by hiding one's true beliefs. It's the truth, this is how we believe. 🏅 – Daniel Kahneman

For most people believes are like tastes. They are not reasoned, they are something that people have and there is no logic behind them.
