Interrogation

Interrogation is the systematic questioning of a person, typically a captured enemy or a hostile subject, to obtain information they may not wish to give. It is distinguished from debriefing, which questions a cooperative subject, by the adversarial relationship at its core, since the interrogator seeks information from someone who is resistant, reluctant, or actively trying to withhold or deceive, which makes interrogation a genuinely difficult skill and a fraught one, surrounded by serious legal, ethical, and practical questions about how far an interrogator may go and what methods actually work. The subject of interrogation carries a heavy weight of history, including the abuses that have discredited coercive methods and prompted legal prohibitions, so understanding interrogation means understanding both its legitimate practice and the boundaries that constrain it.

What actually works, and what does not

A substantial body of experience and research supports a conclusion that runs counter to the popular image of interrogation: that coercion and torture are not only wrong but ineffective, and that rapport-based, skilled questioning is what actually produces reliable information. The image of interrogation as the extraction of truth through pain and pressure is largely a myth, since a subject under torture will say whatever they think will make the pain stop, producing false information as readily as true, and the historical record of coercive interrogation is full of false confessions, fabricated information, and intelligence failures caused by trusting what coercion produced, the fabricator whose false claims under pressure fed the flawed 2003 Iraq WMD assessment being a notable example of how unreliable coerced information can be. Experienced interrogators and the research on the subject instead emphasize rapport-based methods, building a relationship with the subject, understanding their psychology and motivations, and skillfully questioning them in ways that draw out information, which is slower and more demanding than coercion but far more effective at producing reliable intelligence. The skilled interrogator works through psychology, persuasion, and the careful construction of a relationship and a situation that leads the subject to reveal information, rather than through pain and pressure, and the most successful interrogators, including those who interrogated high-value subjects effectively, have consistently reported that rapport and skill, not coercion, are what work. This is both a practical and an ethical conclusion, since the methods that produce reliable information are also the lawful and humane ones, while the coercive methods that are unlawful and inhumane also fail to produce reliable information, so there is no genuine trade-off in which effectiveness requires abandoning ethics, a point that the defenders of coercive interrogation have long disputed but that the weight of experience and evidence does not support.

The history of interrogation includes serious abuses that discredited coercive methods and led to legal prohibitions, a history that shapes how interrogation is understood and constrained today. The use of torture and coercive interrogation, including the methods euphemistically called enhanced interrogation used by the United States after 9/11, generated intense controversy, legal challenges, and ultimately widespread condemnation, both for the moral wrong of the methods and for their questionable effectiveness, and the extensive examination of these practices, including official investigations that questioned whether they produced valuable intelligence, contributed to their prohibition and to a reaffirmation of the rejection of torture. International and domestic law prohibits torture and cruel treatment, and the laws of armed conflict and human rights law establish protections for those in custody, including prisoners of war and detainees, so interrogation is bounded by legal constraints that prohibit coercive and abusive methods, constraints that reflect both the moral rejection of torture and the practical recognition of its ineffectiveness. These legal and ethical boundaries are central to how legitimate interrogation is conducted, defining the methods that may be used, the treatment that must be afforded, and the lines that may not be crossed, and the violation of these boundaries, as in the documented abuses, is both unlawful and, the evidence suggests, counterproductive, undermining the reliability of the information obtained as well as violating the law and the ethical standards that constrain the treatment of those in custody.

Interrogation in the intelligence process

Interrogation, conducted properly, is one source of intelligence among many, valuable for the information a knowledgeable subject can provide but subject to the same need for evaluation and corroboration as any source, since information from interrogation, like information from any source, may be incomplete, mistaken, or deliberately deceptive. A captured enemy may have valuable knowledge of their forces, plans, and operations, which skilled interrogation can draw out, contributing to the intelligence picture, but the information a subject provides must be evaluated for reliability and corroborated against other sources, since the subject may not know as much as hoped, may be mistaken, or may deliberately mislead, so interrogation feeds into the all-source intelligence process that weighs and corroborates information from many sources rather than being trusted on its own. This is especially important given the history of coerced interrogation producing false information, which underscores the need to evaluate carefully what interrogation produces rather than accepting it uncritically, and the reliance on rapport-based methods that produce more reliable information, combined with the evaluation and corroboration of what is obtained, is what makes interrogation a useful rather than a misleading source. The proper conduct of interrogation, therefore, combines the skilled, rapport-based, lawful methods that produce reliable information with the careful evaluation and corroboration of what is obtained, treating interrogation as a valuable but fallible source that contributes to the intelligence picture within the broader process of gathering and assessing intelligence from many sources. This understanding of interrogation, as a skilled and bounded practice that produces useful intelligence through legitimate methods and careful evaluation, rather than as the coercive extraction of truth of popular imagination, reflects both the practical reality of what works and the legal and ethical constraints that properly bound the questioning of those in custody, and it is the understanding that experienced interrogators and the research on the subject support, against the persistent but mistaken and discredited belief that coercion is an effective means of obtaining reliable information from a resistant subject.

Does torture ever produce useful information?

The weight of evidence and experience indicates that torture is unreliable and ineffective at producing accurate information, since a person subjected to torture will say whatever they believe will make it stop, which may be true or false, and cannot be trusted to be accurate, so torture produces false information as readily as true and cannot reliably distinguish between them. The popular belief that torture extracts truth is not supported by the experience of skilled interrogators or the research on interrogation, which consistently find that coercion produces unreliable information, false confessions, and fabrications, while rapport-based methods produce more reliable intelligence, and the historical record includes many cases of coerced information proving false and leading to intelligence failures. The occasional claim that torture produced a specific piece of useful information is difficult to verify and does not establish that torture is reliable, since even if a tortured subject sometimes says something true, the inability to distinguish the true from the false that torture also produces makes it an unreliable method, and the same or better information could likely have been obtained through lawful, effective methods, as the interrogators who used rapport-based approaches successfully have argued. The official examinations of the coercive interrogation used after 9/11 questioned whether it produced valuable intelligence that could not have been obtained otherwise, and the broader conclusion of the experience and research is that torture is both wrong and ineffective, that it does not reliably produce useful information, and that the effective methods are the lawful, humane, rapport-based ones, so there is no genuine case for torture on grounds of effectiveness, since it fails to reliably produce the accurate information that would be its only possible justification, while violating the law and ethical standards that prohibit it. The answer, therefore, is that torture does not reliably produce useful information, that its occasional apparent successes do not establish its reliability given the false information it also produces, and that the effective and lawful approach to interrogation is the rapport-based questioning that skilled interrogators use, not the coercion that is both unlawful and ineffective.
