Brainwashing (also known as mind control, menticide, coercive persuasion, thought control, thought reform, and forced re-education) is the concept that the human mind can be altered or controlled by certain psychological techniques. 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,[1] as well as to change their attitudes, values, and beliefs.[2][3] The term "brainwashing" was first used in English by Edward Hunter in 1950 to describe how the Chinese government appeared to make people cooperate with them during the Korean War. Research into the concept also looked at Nazi Germany, at some criminal cases in the United States, and at the actions of human traffickers. In the late 1960s and 1970s, the CIA's MKUltra experiments failed with no operational use of the subjects. Scientific and legal debate followed, as well as media attention, about the possibility of brainwashing being a factor when Lysergic acid diethylamide (LSD) was used,[4] or in the conversion of people to groups which are considered to be cults.[5] The concept of brainwashing is not now generally accepted as a scientific fact.[6][7] In casual speech, "brainwashing" and its verb form, "brainwash", are used figuratively to describe the use of propaganda to persuade or sway public opinion.[8]
