Brainwash

Brainwashing is the systematic effort to get someone to adopt a particular deception, loyalty, instruction, or doctrine. It refers in general to psychological techniques that manipulate action or thought against a person's will, desire, or knowledge. It attempts to damage individual or group attitudes, frames of reference, beliefs, values or loyalties by demonstrating that current thinking patterns and attitudes are wrong and need change. It is said to reduce its subject's ability to think critically or independently, to allow the introduction of new, unwanted thoughts and ideas into their minds.
