One of the first things we should remember is that the two psychologists that lead the program used the techniques adopted by North Korea during the Korean War. The US undertook the study to determine why American POWs made false declarations. In other words, these techniques compelled prisoners to lie not tell the truth.
Rupert Stone of Newsweek looked at the scientific studies on torture.
One study by Shane O'Mara.
Meanwhile, compelling scientific evidence is emerging that torture and coercion are, at best, ineffective means of gathering intelligence. Worse, as Shane O’Mara, a professor of experimental brain research at Trinity College Dublin, wrote in a recent
book,
Why Torture Doesn’t Work: The Neuroscience of Interrogation, torture can produce false information by harming those areas of the brain associated with memory. O’Mara marshals a large amount of scientific literature to make his point. In one important
experiment from 2006, psychiatrist Charles Morgan and colleagues subjected a group of
special operations soldiers to prisoner-of-war conditions (including food and sleep deprivation and temperature extremes).
These soldiers were highly trained and physically fit, and, unlike most detainees, they were motivated to cooperate. But even they exhibited a remarkable deterioration in memory as a result of these stressful conditions. According to Carle, enhanced interrogation techniques have similar effects. “It is obvious that sleep deprivation and temperature extremes disorient the detainee—they are designed to do so,” he says.

Indeed, the Navy’s Survival, Evasion, Resistance and Escape school used to subject U.S. soldiers to waterboarding as part of their resistance training (it stopped in 2007), and former instructor Malcolm Nance says the procedure does not elicit reliable information. It does, on the other hand, generate false confessions. “The captive will say absolutely anything and agree to anything to make the torture stop,” says Nance. Most of those subjected to waterboarding, he says, confess as a result—and their distress is so intense, they do not even remember confessing. In a recent
BBC documentary, for which Nance served as a consultant,
a volunteer underwent waterboarding and confessed to “being born a bunny rabbit.” He had no recollection of making such an admission.
What scientists have found is the same thing the Americans learned after the Korean War; torture, including sleep deprivation, waterboarding, etc, elicits false information.
Bolding is mine.
