Indoctrination

Indoctrination is when somebody or something teaches you a certain way of thinking and trying to make you believe something or agree with them. It is kind of like brainwashing or training so that you start to think and act the same way. Indoctrination can be used by parents, schools, governments, and religions to try to influence people and make them believe certain ideas.
