During the Korean War, Korean and Chinese captors reportedly brainwashed American POWs held in prison camps. Several prisoners ultimately confessed to waging germ warfare — which they hadn't — and pledged allegiance to communism by the end of their captivity.

At least 21 soldiers refused to come back to the United States when they were set free. It sounds like a lot but skeptics point out that 22,000 POWs from communist countries refused repatriation versus only 21 American soldiers [source: Adams], leaving some to believe that the disparity was a result of brainwashing.


However, there are psychologists who say the apparent conversion of American POWs during that particular war was the result of psychological experiments and torture techniques used to extract confessions and information, not "brainwashing." In fact, most POWs in the Korean War were not converted to communism at all, which leads to the question of reliability: Is brainwashing a system that produces similar results across cultures and personality types, or does it hinge primarily on the target's susceptibility to influence?

What Is Brainwashing?

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.

While most psychologists believe that brainwashing is possible under the right conditions, some see it as improbable or at least as a less severe form of influence than the media portrays it to be.


Some definitions of brainwashing require the presence of the threat of physical harm. Under these definitions, most extremist cults do not practice true brainwashing since they typically do not physically abuse recruits. Other definitions rely on "nonphysical coercion and control" as an equally effective means of asserting influence.

Regardless of which definition you use, many experts believe that even under ideal brainwashing conditions, the effects of the process are most often short-term — the brainwashing victim's old identity is not in fact eradicated by the process, but instead is in hiding, and once the "new identity" stops being reinforced the person's old attitudes and beliefs will start to return [source: Psychological Harassment Information Association].

Basically, if you coerce someone into abandoning their religious beliefs in favor of a new atheist identity, they'll likely re-embrace those old beliefs once you stop pushing the new identity onto them.


Social Influence

In psychology, the study of brainwashing, often referred to as thought reform, falls into the sphere of "social influence." This type of influence happens every minute of every day. It's the collection of ways in which people can change other people's attitudes, beliefs and behaviors.

For instance, the compliance method aims to produce a change in a person's behavior and is not concerned with his attitudes or beliefs. It's the "just do it" approach. Persuasion, on the other hand, aims for a change in attitude. For example, "Do it because it'll make you feel good/happy/healthy/successful."


The education method (or "propaganda method," which is when you don't believe in what's being taught) goes for the social influence gold, trying to affect a change in the person's beliefs. For instance, "Do it because you know it's the right thing to do."

Brainwashing is a severe form of social influence that combines all of these approaches to cause changes in someone's way of thinking without that person's consent and often against their will [source: Working Psychology].

Isolation and Dependency

Because brainwashing is such an invasive form of influence, it requires the complete isolation and dependency of the subject, which is why you mostly hear of brainwashing occurring in prison camps or totalist cults.

The agent (the brainwasher) must have complete control over the target (the brainwashee) so that sleeping, eating, using the bathroom and fulfilling other basic human needs depends on the will of the agent.

In the brainwashing process, the agent systematically breaks down the target's identity to the point that it falls apart. The agent then replaces it with another set of behaviors, attitudes and beliefs that work in the target's current environment [source: Britannica].

Let's examine an expert's description of the brainwashing process and find out what makes an easy target.

In the late 1950s, psychologist Robert Jay Lifton studied former prisoners of Korean War and Chinese war camps. He determined that they'd undergone a multistep process that began with attacks on the prisoner's sense of self and ended with what appeared to be a change in beliefs. Lifton ultimately defined a set of steps involved in the brainwashing cases he studied:


  1. Assault on identity
  2. Guilt
  3. Self-betrayal
  4. Breaking point
  5. Leniency
  6. Compulsion to confess
  7. Channeling of guilt
  8. Releasing of guilt
  9. Progress and harmony
  10. Final confession and rebirth

Each of these stages takes place in an environment of isolation, meaning all "normal" social reference points are unavailable, and mind-clouding techniques like sleep deprivation and malnutrition are typically part of the process.

There is often the presence or constant threat of physical harm, which adds to the target's difficulty in thinking critically and independently [source: Changing Minds].

We can roughly divide the process Lifton identified into three stages: breaking down the self, introducing the possibility of salvation and rebuilding the self.


Stage 1: Breaking Down the Self

According to Lifton, the first stage of brainwashing involves breaking down an individual's sense of self. This is achieved through isolation, deprivation of familiar social connections and manipulation of their environment. There are four steps in this stage, including:

Assault on Identity: You Are Not Who You Think You Are.

This is a systematic attack on a target's sense of self (also called the identity or ego) and their core belief system. The agent denies everything that makes the target who they are:


  • "You are not a soldier."
  • "You are not a man."
  • "You are not defending freedom."

The target is under constant attack for days, weeks or months, to the point that they become exhausted, confused and disoriented. In this state, their beliefs seem less solid.

Guilt: You Are Bad.

While the identity crisis is setting in, the agent is simultaneously creating an overwhelming sense of guilt in the target. They repeatedly and mercilessly attacks the subject for any "sin" the target has committed, large or small.

The agent may criticize the target for everything from the "evilness" of their beliefs to the way they eat too slowly. The target begins to feel a general sense of shame that everything they do is wrong.

Self-Betrayal: Agree With Me That You Are Bad.

Once the subject is disoriented and drowning in guilt, the agent forces them (either with the threat of physical harm or of continuance of the mental attack) to denounce their family, friends and peers who share the same "wrong" belief system that they hold.

This betrayal of the target's beliefs and of people they feel a sense of loyalty to increases the shame and loss of identity they are already experiencing.

Breaking Point: Who Am I, Where Am I and What Am I Supposed to Do?

With their identity in crisis, experiencing deep shame and having betrayed what they have always believed in, the target may undergo what people in the lay community refer to as a "nervous breakdown," or a collection of severe symptoms that can indicate any number of psychological disturbances.

It may involve uncontrollable sobbing, deep depression and general disorientation. The target may have lost their grip on reality and have the feeling of being completely lost and alone.

When the target reaches their breaking point, their sense of self is pretty much up for grabs — they have no clear understanding of who they are or what is happening to them. At this point, the agent sets up the temptation to convert to another belief system that will save the target from their misery.


Stage 2: The Possibility of Salvation

In Lifton's second stage of brainwashing, agents present the individual with a perceived pathway to salvation or relief from their suffering. This creates hope and dependence, as the target begins to believe that compliance with the agent's demands is the only way to attain relief or safety, deepening their vulnerability to manipulation.


First, the brainwasher shows leniency. With the target in a state of crisis, the agent offers some small kindness or reprieve from the abuse. The agent may offer the target a drink of water or take a moment to ask them what they miss about home.


In a state of breakdown resulting from an endless psychological attack, the small kindness seems huge, and the target may experience a sense of relief and gratitude completely out of proportion to the offering, as if the agent has saved their life.

Compulsion to Confess

Next, the brainwasher offers an opportunity for confession. For the first time in the brainwashing process, the target is faced with the contrast between the guilt and pain of identity assault and the sudden relief of leniency.

The target may feel a desire to reciprocate the kindness offered to them, and at this point, the agent may present the possibility of confession as a means to relieving guilt and pain.

Channeling of Guilt

Guilt is the real reason many subjects are in pain. After weeks or months of assault, confusion, breakdown and moments of leniency, the target's guilt has lost all meaning — they're not sure what they have done wrong, they just know they are wrong.

This creates something of a blank slate that lets the agent fill in the blanks: They can attach that guilt, that sense of "wrongness," to whatever they want.

The agent attaches the target's guilt to the belief system the agent is trying to replace. The target comes to believe it is their belief system that is the cause of their shame. The contrast between old and new has been established: The old belief system is associated with psychological (and usually physical) agony; and the new belief system is associated with the possibility of escaping that agony.

Releasing Guilt

Next, releasing the guilt is a key step. The embattled target is relieved to learn there is an external cause of their wrongness, that they are not inescapably bad — this means they can escape their wrongness by escaping the wrong belief system.

All they have to do is denounce the people and institutions associated with that belief system, and they won't be in pain anymore.

The target has the power to release themself from wrongness by confessing to acts associated with their old belief system. With the target's full confessions, they have completed the psychological rejection of their former identity. It is now up to the agent to offer the target a new one [source: Singer].


Stage 3: Rebuilding the Self

Once those critical early stages of brainwashing are complete, it's time to move on to a more harmonious — if destructive — relationship.

Progress and Harmony

The target is now presented with a path to alleged progress and harmony. In other words, "If you want, you can choose good." At this stage, the agent stops the abuse, offering the target physical comfort and mental calm in conjunction with the new belief system. The target is made to feel that they must choose between old and new, giving them the sense that their fate is in their own hands.


The target has already denounced their old belief system in response to leniency and torment, and making a "conscious choice" in favor of the contrasting belief system helps to further relieve their guilt: If they truly believe, then they really didn't betray anyone.

The choice is not a difficult one: The new identity is safe and desirable because it is nothing like the one that led to their breakdown.

Final Confession and Rebirth

Next comes the final confession and rebirth: "I choose good." Contrasting the agony of the old with the peacefulness of the new, the target chooses the new identity, clinging to it like a life preserver. They reject their old belief system and pledges allegiance to the new one that is going to make their life better.

At this final stage, there are often rituals or ceremonies to induct the converted target into their new community. This stage has been described by some brainwashing victims as a feeling of "rebirth" [source: Singer].

From Firsthand Accounts

A brainwashing process like the one discussed above has not been tested in a modern laboratory setting, because it's damaging to the target and would therefore be an unethical scientific experiment. Lifton created this description from firsthand accounts of the techniques used by captors in the Korean War and other instances of "brainwashing" around the same time.

Since Lifton and other psychologists have identified variations on what appears to be a distinct set of steps leading to a profound state of suggestibility, an interesting question is why some people end up brainwashed and others don't.


What Do Brainwashing Targets Have in Common?

Certain personality traits of the brainwashing targets can determine the effectiveness of the process. People who commonly experience great self-doubt, have a weak sense of identity and show a tendency toward guilt and absolutism (black-and-white thinking) are more likely to be successfully brainwashed, while a strong sense of identity and self-confidence can make a target more resistant to brainwashing.

Some accounts show that faith in a higher power can assist a target in mentally detaching from the process. People who've suffered abuse in childhood, have been exposed to eccentric family patterns and who have substance abuse issues are also more likely to be influenced [source: Curtis].



Mental detachment is one of the POW-survival techniques now taught to soldiers as part of their training. It involves the target psychologically removing oneself from their actual surroundings through visualization, the constant repetition of a mantra and various other meditative techniques.

The military also teaches soldiers about the methods used in brainwashing, because a target's knowledge of the process tends to make it less effective [source: Webb].


While the U.S. consciousness was turned to brainwashing in the 1950s in the aftermath of the Korean War, brainwashing has been around for longer than that. Scholars have traced the roots of systematic thought reform to the prison camps of communist Russia in the early 1900s, when political prisoners were routinely "reeducated" to the communist view of the world.

But it was when the practice spread to China and the writings of Chairman Mao Zedong ("The Little Red Book") that the world started to take notice [source: Boissoneault].


Brainwashing Then and Now

In 1929, Mao Zedong, who would later lead the Chinese Communist Party, used the phrase "sīxiǎng dòuzhēng" (meaning "thought struggle") to describe a process of brainwashing.

Political prisoners in China and Korea were reportedly subjected to communist-conversion techniques as a matter of course. The modern concept and the term "brainwashing" was first used by journalist Edward Hunter in 1951 to describe what had happened to American POWs during the Korean War.


In his book, Brainwashing in Red China, Hunter introduced the concept at a time when Americans were already afraid: It was the Cold War, and America panicked at the idea of mass communist indoctrination through "brainwashing" — they might be converted and not even know it! [source: Boissoneault]

MKULTRA and Cold War Paranoia

In the wake of the Korean War revelations, the U.S. government seemed to fear it was falling behind in the weapons race, because it began its own mind-control research.

In 1953, the CIA began a program called MKULTRA. In one study, the CIA supposedly gave subjects (including the famed Timothy Leary) LSD in order to study the effects of mind-altering drugs and gauge the effectiveness of psychedelics at inducing a brainwashing-friendly state of mind.

The results were not that encouraging, and subjects were supposedly harmed by the experiments. Drug experimentation by the CIA was officially canceled by Congress in the 1970s, although some claim it still happens under the radar.

Public interest in brainwashing briefly subsided after the Cold War but resurfaced in the 1960s and 1970s with the emergence of countless non-mainstream political and religious movements during that era. Parents who were horrified by their children's new beliefs and activities were sure they'd been brainwashed by a "cult."

The mass suicides and killing sprees committed by a small percentage of those cults seemed to validate the brainwashing fears. Some parents went so far as to have their children kidnapped by "deprogrammers" to remove them from the influence of cult leaders.

Hearst's Brainwashing Defense

One supposed victim of brainwashing at that time was Patty Hearst, heiress to the Hearst publishing fortune, who would later use a brainwashing defense when she was on trial for bank robbery. Hearst became famous in the early 1970s after she was kidnapped by the Symbionese Liberation Army (the SLA, which some deem a "political cult") and ended up joining the group.

Hearst reports that she was locked in a dark closet for several days after her kidnapping and was kept hungry, tired, brutalized and afraid for her life while SLA members bombarded her with their anti-capitalist political ideology.

Within two months of her kidnapping, Patty had changed her name, issued a statement in which she referred to her family as the "pig-Hearsts" and appeared on a security tape robbing a bank with her kidnappers.

Patty Hearst stood trial for bank robbery in 1976, defended by the famous F. Lee Bailey. The defense claimed that Hearst was brainwashed by the SLA and would not have committed the crime otherwise; in her mental state, she could not tell right from wrong.

Hearst was found guilty and sentenced to seven years in prison. She only served two; in 1979, President Carter commuted her sentence [source: Wilson].


The Lee Boyd Malvo Case

Another "insanity by brainwashing" defense hit the courtroom in 2003, when Lee Boyd Malvo stood trial for his role in the 2002 sniper attacks in and around Washington, D.C. The 17-year-old Malvo and 42-year-old John Allen Muhammad shot 10 people and wounded three in a killing spree.

The defense claimed that the teenaged Malvo was brainwashed by Muhammad into committing the crimes, which he would not have committed if he weren't under Muhammad's control. As Carlin Flora wrote in Psychology Today back in 2003:

"Muhammad plucked 15-year-old Malvo from the Caribbean island of Antigua, where his mother had abandoned him, and brought him to the U.S. in 2001. An army veteran, Muhammad filled the teen's head with visions of an impending race war and trained Malvo in marksmanship. He isolated Malvo, steeped him to his own idiosyncratic, vitriolic brand of Islam and imposed a strict diet and exercise regimen on his 'adopted' son."

The argument was that Malvo was brainwashed, so he could not tell right from wrong, to the point that he laughed when describing the crimes.

"Brainwashing is not a legal term, and is probably shorthand for a 'lack of intention,'" said Richard Uviller, professor of law emeritus at Columbia University to Psychology Today at the time of the trial. "The defense has to show that at the time Malvo pulled the trigger, he did not intend to hurt the victims. Insanity defenses in general are rarely asserted and almost never prevail" [source: Flora].

Malvo was found guilty and sentenced to life in prison without parole in 2004 (Muhammad was sentenced to death in a separate trial) [sources: CNN]. Due to changes in sentencing laws for minors, Malvo may be eligible for parole after 20 years. Muhammad was executed in 2009 [source: Associated Press]. In the Malvo case, the jury didn't buy the "brainwashing" defense.

R. Kelly's Brainwashing Accusations

More recently, in 2021, R&B singer R. Kelly was found guilty of sexual exploitation of a child, bribery, racketeering and sex trafficking involving five victims according to NPR. Parents of two young women as well as some of Kelly's inner circle said the singer brainwashed women and kept them in a cult where he controlled everything they did.

In September 2022, Kelly was convicted of 6 more counts of child sex abuse in his federal trial in Chicago. There had been nearly 30 years of allegations of Kelly exploiting women, but "brainwashing" wasn't part of his lengthy list of charges.

Fictional Brainwashing

In 1962's "The Manchurian Candidate," brainwashing produces a robot-like assassin incapable of overriding the control commands he's been programmed with. Stanley Kubrick's "A Clockwork Orange" (1971) positions institutional brainwashing as an option for violent convicts looking to shorten their sentences.

In 1997's "Conspiracy Theory," a government-brainwashed assassin seeks to prove that some very powerful people have been tampering with his mind. In 2017's "Get Out" writer-director Jordan Peele explores the theme of brainwashing within the context of racial identity. In the film, Chris, a Black man who's in a relationship with a white woman named Rose, gets hypnotically manipulated by Rose's mother, symbolizing the exploitation of race.

Modern literature and film use the brainwashing scenario pretty liberally. It gets to the very nature of humanity: Are we all ultimately reducible to puppets? For example, the protagonist in George Orwell's "1984" undergoes a classic case of brainwashing that ends with the famous concession to his tormentors: "two plus two equals five."

The Future of Brainwashing

The future of brainwashing, if Hollywood and the conspiracy theorists are to be trusted, involves much more high-tech approaches, like say, implanting a chip in someone's brain. But most scientists agree that the field of neurology is nowhere close to that level of understanding of the human brain.

As the term "brainwashing" has now been around for decades, it is naturally facing an evolution of sorts. The term is thrown around pretty liberally, often used to describe the people immersed in controversial social systems, such as QAnon or the anti-vaxxer movement [source: Rodriguez].

However, many psychologists believe that using the term "brainwashing" to describe what's happening to these people is inaccurate as the true thought-reform process of brainwashing requires isolation and absolute dependence of the subject to be effective.

By comparison, involvement in groups like QAnon is voluntary, and their success is often precipitated by the involvement of trusted friends, family members and other like-minded individuals [source: Lokere].

Coercion and Conditioning

Instead, some scientists are gravitating toward the use of different terms to describe situations such as those, which are nonetheless hallmarked by big changes in attitude and actions. Coercion is one such alternative term, used to describe an incident where someone does something they don't really agree with because they feel threatened in some way.

So, they don't necessarily align with the belief, but they have no choice but to follow suit. For example, the wife who goes along with QAnon conspiracy theories her husband spouts because it keeps the peace in her marriage.

Also, many people are not so much brainwashed as they are conditioned. If a person is repeatedly praised for certain behaviors and penalized for others he or she naturally gravitates toward the desired behavior. This is used all the time with training children or dogs to behave, but it's definitely not considered brainwashing under those circumstances.

Lastly, people who experience conversion to drastically different beliefs or emotions are usually inspired by a life-changing event, such as a near-miss accident, loss of a loved one or other major experience. So, no one is really forcibly telling the person what to do or how to behave, but they seek out other people with similar views to feel validated [source: Moore].

It's just not that easy to change a person's core personality and belief system, and the incorrect use of "brainwashing" can do quite the disservice.

Brainwashing FAQ

What are some aspects of brainwashing?
Brainwashing entails: (1) Isolation from the familiar, inclusive of, but not limited to colleagues, family or the environment, (2) Absolute submission and (3) A rigid system of reward and punishment in terms of obedience and unwillingness to cooperate, respectively.
Is brainwashing a criminal act?
Brainwashing is perhaps best known in the context of prisoners, war criminals, cults and more recently, child custody cases. It is well recognized as a war crime and is deemed impermissible according to the Geneva Conventions. However, it isn’t technically illegal in the United States, though there are some laws regarding manipulation.
What does brainwashing achieve?
Someone is said to be brainwashed when their mind is controlled or altered by force, changing what they believe, think, value and do.
Can a person actually be brainwashed?
The human mind can be controlled using psychological techniques, though psychologists disagree about the extent to which a person can be brainwashed. Film and television tends to exaggerate what brainwashing is and how far this extreme form of social influence can go.
