Inducing a person to modify his or her beliefs, attitudes, or behavior by conditioning through various forms of pressure or torture.
Indoctrination that forces people to abandon their beliefs in favor of another set of beliefs.

Brainwashing techniques range from vocal persuasion and threats to punishment, physical deprivation, mind-altering drugs, and severe physical torture.
