Brainwashing--also called mind control--is a complex process that overrides a person’s normal beliefs, will, or desires and replaces them with the opinions or will of the person or group doing the brainwashing.

Brainwashing 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, as well as to change their attitudes, values, and beliefs.

Brainwashing is a term that refers to both coercive persuasion and a systematic process aimed at altering an individual's beliefs, attitudes and behaviors through various psychological and manipulative means. This process often involves isolation, indoctrination, threats, rewards and the use of propaganda to remove free will.

The techniques of brainwashing typically involve isolation from former associates and sources of information; an exacting regimen requiring absolute obedience and humility; strong social pressures and rewards for cooperation; physical and psychological punishments for non-cooperation ranging from social ostracism and criticism, deprivation of food, sleep, and social contacts, to bondage and torture; and continual reinforcement.

Brainwashing only works when the brainwasher is in a superior position to the victim. This means that the victim has to be broken down, so the brainwasher can rebuild the victim in his or her image. This can be done through mental, emotional, or ultimately physical means for long enough to physical and emotionally wear down the target.
