Torture has been carried out since ancient times. However, in the eighteenth and nineteenth centuries, many Western countries abolished the official use of torture in the
judicial system, although it continued to be used throughout the world. Public opinion research shows general opposition to torture. It is
prohibited under international law for all states
under all circumstances and is explicitly forbidden by several treaties. Opposition to torture stimulated the formation of the
human rights movement after

Definitions
Torture is defined as the deliberate infliction of severe pain or suffering on someone under the control of the perpetrator. The treatment must be inflicted for a specific purpose, such as punishment and forcing the victim to confess or provide information. The definition put forth by the
United Nations Convention against Torture only considers torture carried out by the state. Most legal systems include agents acting on behalf of the state, and some definitions add
non-state armed groups,

, or private individuals working in state-monitored facilities (
such as hospitals). The most expansive definitions encompass anyone as a potential perpetrator. Although torture is usually classified as more severe than
cruel, inhuman, or degrading treatment (CIDT), the threshold at which treatment can be classified as torture is the most controversial aspect of its definition; the interpretation of torture has broadened over time. Another approach, preferred by scholars such as
Manfred Nowak and
Malcolm Evans, distinguishes torture from CIDT by considering only the torturer's purpose, and not the severity. Other definitions, such as that in the
Inter-American Convention to Prevent and Punish Torture, focus on the torturer's aim "to obliterate the personality of the victim".
History
Pre-abolition
Torture was legally and morally acceptable in most ancient, medieval, and early modern societies. There is archaeological evidence of torture in
Early Neolithic
The Neolithic or New Stone Age (from Greek 'new' and 'stone') is an archaeological period, the final division of the Stone Age in Mesopotamia, Asia, Europe and Africa (c. 10,000 BCE to c. 2,000 BCE). It saw the Neolithic Revolution, a wi ...

Historically, torture was seen as a reliable way to elicit the truth, a suitable punishment, and deterrence against future offenses.

Torture was rare in
early medieval Europe but became more common between 1200 and 1400. Because medieval judges used an exceptionally high standard of proof, they would sometimes authorize torture when
circumstantial evidence tied a person to a
capital crime if there were fewer than the
two eyewitnesses required to convict someone in the absence of a confession. Torture was still a labor-intensive process reserved for the most severe crimes; most torture victims were men accused of murder, treason, or theft. Medieval

Abolition and continued use
Torture remained legal in Europe during the seventeenth century, but its practice declined. Torture was already of marginal importance to European
criminal justice systems by its formal abolition in the 18th and early 19th centuries. Theories for why torture was abolished include the rise of
Enlightenment ideas about the value of the human person, the lowering of the standard of proof in criminal cases, popular views that no longer saw pain as morally redemptive, and the expansion of imprisonment as an alternative to executions or painful punishments. It is not known if torture also declined in non-Western states or European colonies during the nineteenth century. In China, judicial torture, which had been practiced for more than two millennia, was banned in 1905 along with flogging and ''

dismemberment) as a means of execution, although

Prevalence
Most countries practice torture, although few acknowledge it. The international prohibition of torture has not completely stopped torture; instead, states have changed which techniques are used and denied, covered up, or
outsourced torture programs. Measuring the rate at which torture occurs is difficult because it is typically committed in secrecy, and abuses are likelier to come to light in
open societies where there is a commitment to protecting human rights. Many torture survivors, especially those from poor or marginalized populations, are unwilling to report. Monitoring has focused on police stations and prisons, although torture can also occur in other facilities such as
immigration detention and
youth detention centers. Torture that occurs outside of custody—including extrajudicial punishment, intimidation, and
crowd control—has traditionally not been counted, even though some studies have suggested it is more common than torture in places of detention. There is even less information on the prevalence of torture before the twentieth century. Although it is often assumed that men suffer torture at a higher rate than women, there is a lack of evidence. Some quantitative research has estimated that torture rates are either stagnant or increasing over time, but this may be a measurement effect.
Although liberal democracies are less likely to abuse their citizens, they may practice torture against marginalized citizens and non-citizens to whom they are not democratically accountable. Voters may support violence against out-groups seen as threatening;
majoritarian institutions are ineffective at preventing torture against minorities or foreigners. Torture is more likely when a society feels threatened because of wars or crises, but studies have not found a consistent relationship between the use of torture and terrorist attacks.
Torture is directed against certain segments of the population, who are denied the protection against torture given to others. Torture of
political prisoners and torture during armed conflicts receive more attention compared to torture of the poor or criminal suspects. Most victims of torture are suspected of crimes; a disproportionate number of victims are from poor or marginalized communities. Groups especially vulnerable to torture include unemployed young men, the

Perpetrators

Since most research has focused on torture victims, less is known about the perpetrators of torture. Many torturers see their actions as serving a higher political or ideological goal that justifies torture as a legitimate means of protecting the state. Fear is often the motivation for torture, and it is typically not a rational response as it is usually ineffective or even counterproductive at achieving the desired aim. Torture victims are often viewed by the perpetrators as severe threats and
enemies of the state. Studies of perpetrators do not support the common assumption that they are psychologically pathological. Most perpetrators do not volunteer to be torturers; many have an innate reluctance to employ violence, and rely on
coping mechanisms, such as alcohol or drugs. Psychiatrist
Pau Pérez-Sales finds that torturers act from a variety of motives such as ideological commitment, personal gain, group belonging, avoiding punishment, or avoiding guilt from previous acts of torture.
Although it is often assumed that torture is ordered from above at the highest levels of government, sociologist
Jonathan Luke Austin argues that government authorization is a necessary but not sufficient condition for torture to occur, given that a specific order to torture rarely can be identified. In many cases, a combination of dispositional and situational effects lead a person to become a torturer. In most cases of systematic torture, the torturers were desensitized to violence by being exposed to physical or

The contribution of bureaucracy to torture is under-researched and poorly understood. Torturers rely on both active supporters and those who ignore it. Military, intelligence, psychology, medical, and legal professionals can all be complicit in torture. Incentives can favor the use of torture on an institutional or individual level, and some perpetrators are motivated by the prospect of career advancement. Bureaucracy can diffuse responsibility for torture and help perpetrators excuse their actions. Maintaining secrecy is often essential to maintaining a torture program, which can be accomplished in ways ranging from direct censorship, denial, or mislabeling torture as something else, to offshoring abuses to outside a state's territory. Along with official denials, torture is enabled by
moral disengagement from the victims and

Once a torture program is begun, it is difficult or impossible to prevent it from escalating to more severe techniques and expanding to larger groups of victims, beyond what is originally intended or desired by decision-makers. Sociologist
Christopher J. Einolf argues that "torture can create a vicious cycle in which a fear of
internal enemies leads to torture, torture creates
false confessions, and false confessions reinforce torturers' fears, leading to a spiral of paranoia and ever-increasing torture"—similar to a

Purpose
Punishment
Torture for punishment dates back to antiquity and is still employed in the twenty-first century.
A common practice in countries with dysfunctional justice systems or overcrowded prisons is for police to apprehend suspects, torture them, and release them without a charge. Such torture could be performed in a police station, the victim's home, or a public place. In South Africa, the police have been observed handing suspects over to

. Authoritarian regimes often resort to indiscriminate repression because they cannot accurately identify potential opponents. Many insurgencies lack the necessary infrastructure for a torture program and instead intimidate by killing. Research has found that state torture can extend the lifespan of terrorist organizations, increase incentives for insurgents to use violence, and radicalize the opposition. Another form of torture for deterrence is violence against migrants, as has been reported during
pushbacks on the European Union's external borders.
Confession
Torture has been used throughout history to extract confessions from detainees. In 1764, Italian reformer
Cesare Beccaria

ing for extracting a confession from a suspect, but presents a higher risk of false confession. Many torture victims will say whatever the torturer wants to hear to end the torture. Others who are guilty refuse to confess, especially if they believe it would only bring more torture or punishment. Medieval justice systems attempted to counteract the risk of false confession under torture by requiring confessors to provide
falsifiable details about the crime, and only allowing torture if there was already some evidence against the accused. In some countries, political opponents are tortured to force them to confess publicly as a form of
state propaganda.
Interrogation

The use of torture to obtain information during interrogation accounts for a small percentage of worldwide torture cases; its use for obtaining confessions or intimidation is more common. Although interrogational torture has been used in
conventional wars, it is even more common in
asymmetric war or civil wars. The
ticking time bomb scenario is extremely rare, if not impossible, but is cited to justify torture for interrogation.
Fictional portrayals of torture as an effective interrogational method have fueled misconceptions that justify the use of torture. Experiments comparing torture with other interrogation methods cannot be performed for ethical and practical reasons, but most scholars of torture are skeptical about its efficacy in obtaining accurate information, although torture sometimes has obtained actionable intelligence. Interrogational torture can often shade into confessional torture or simply into entertainment, and some torturers do not distinguish between interrogation and confession.
Methods

A wide variety of techniques have been used for torture. Nevertheless, there are limited ways of inflicting pain while minimizing the risk of death. Survivors report that the exact method used is not significant. Most forms of torture include both physical and psychological elements and multiple methods are typically used on one person. Different methods of torture are popular in different countries. Low-tech methods are more commonly used than high-tech ones, and attempts to develop scientifically validated torture technology have failed. The
prohibition of torture motivated a shift to methods that do not leave marks to aid in deniability and to deprive victims of legal redress. As they faced more pressure and scrutiny, democracies led the innovation in clean torture practices in the early twentieth century; such techniques diffused worldwide by the 1960s. Patterns of torture differ based on a torturer's time limits—for example, resulting from legal limits on pre-trial detention.

Effects
Torture is one of the most devastating experiences that a person can undergo. Torture aims to break the victim's will and destroy the victim's agency and personality. Torture survivor
Jean Améry
Jean Améry (31 October 191217 October 1978), born Hans Chaim Maier, was an Austrian-born essayist whose work was often informed by his experiences during World War II. His most celebrated work, ''At the Mind's Limits: Contemplations by a Surviv ...
argued that it was "the most horrible event a human being can retain within himself" and that "whoever was tortured, stays tortured". Many torture victims, including Améry, later die by suicide. Survivors often experience social and financial problems. Circumstances such as
housing insecurity,
family separation, and the uncertainty of applying for
asylum in a safe country strongly impact survivors' well-being.
Death is not an uncommon outcome of torture. Understanding of the link between specific torture methods and health consequences is lacking. These consequences can include

sleep disturbance. An average of 40 percent have long-term post-traumatic stress disorder (PTSD), a higher rate than for any other traumatic experience. Not all survivors or rehabilitation experts support using medical categories to define their experience, and many survivors remain
psychologically resilient.
Criminal prosecutions for torture are rare and most victims who submit formal complaints are not believed. Despite the efforts for evidence-based evaluation of the scars from torture such as the
Istanbul Protocol, most physical examinations are inconclusive. The effects of torture are one of several factors that usually result in inconsistent testimony from survivors, hampering their effort to be believed and secure either refugee status in a foreign country or criminal prosecution of the perpetrators.
Although there is less research on the effects of torture on perpetrators, they can experience
moral injury or
trauma symptoms similar to the victims, especially when they feel guilty about their actions. Torture has corrupting effects on the institutions and societies that perpetrate it. Torturers forget important investigative skills because torture can be an easier way than time-consuming police work to achieve high conviction rates, encouraging the continued and increased use of torture. Public disapproval of torture can harm the international reputation of countries that use it, strengthen and radicalize violent opposition to those states, and encourage adversaries to themselves use torture.
Public opinion
Studies have found that most people around the world oppose the use of torture in general. Some hold definite views on torture; for others, torture's acceptability depends on the victim. Support for torture in specific cases is correlated with the belief that torture is effective and used in ticking time bomb cases. Women are more likely to oppose torture than men. Nonreligious people are less likely to support the use of torture
than religious people, although for the latter group, increased
religiosity increases opposition to torture. The personality traits of

, and
retributivism are correlated with higher support for torture; embrace of democratic values such as liberty and equality reduces support for torture. Public opinion is most favorable to torture, on average, in countries with low per capita income and high levels of
state repression. Public opinion is an important constraint on the use of torture by states.

evidence obtained under torture may not be admitted in court, and deporting a person to another country where they are likely to face torture
is forbidden. Even when it is illegal under national law, judges in many countries continue to admit evidence obtained under torture or ill treatment. It is disputed whether ratification of the CAT decreases, does not affect, or even increases the rate of torture in a country.

Prevention
Torture prevention is complicated both by lack of understanding about why torture occurs and by lack of application of what is known. Torture proliferates in situations of
incommunicado detention. Because the risk of torture is highest directly after an arrest, procedural safeguards such as immediate access to a lawyer and notifying relatives of an arrest are the most effective ways of prevention. Visits by independent monitoring bodies to detention sites can also help reduce torture. Legal changes that are not implemented in practice have little effect on the incidence of torture. Legal changes can be particularly ineffective in places where the law has limited legitimacy or is routinely ignored.

, frustrating prevention efforts because torturers can find a way around rules. Safeguards against torture in detention can be evaded by beating suspects during round-ups or on the way to the police station. General training of police to improve their ability to investigate crime has been more effective at reducing torture than specific training focused on human rights. Institutional police reforms have been effective when abuse is systematic. Political scientist
Darius Rejali criticizes torture prevention research for not figuring out "what to do when people are bad; institutions broken, understaffed, and corrupt; and habitual serial violence is routine".
