Brainwashing
From NonSpiritual
Forcible or manipulative indoctrination into a new set of attitudes and beliefs.
From Wikipedia[1]:
Brainwashing (also known as thought reform or as re-education) consists of any effort aimed at instilling certain attitudes and beliefs in a person — beliefs sometimes unwelcome or in conflict with the person's prior beliefs and knowledge, in order to affect that individual's value system and subsequent thought-patterns and behaviors.
A brainwashed person usually experiences Cognitive Dissonance and may require Deprogramming in order to be reverse the effects of brainwashing.
