The faith and education of a country, a city, or a family play a key role.

They can't see a larger field of view, so their thoughts and choices are confined to a circle.
If we stick to what the country teach us and what the we were taught in school then we are doomed. Remember that the government won't teach things that will overthrow them, remember how they're not talking about school shootings and gun control in the US and how they always tell the stories where the US was supposed to win? The owners of this world don't want a critical thinking public, it's against their interest.
