Advocates often portray torture, like waterboarding, as black magic that quickly enables the interrogator to break through his subject’s defenses and force him to divulge the location of the bomb that will destroy Los Angeles. But what does the scientific literature say? A 2006 Intelligence Science Board flatly noted that there was no data supporting the claim that torture produces reliable results. The 372-page report would be summed up by this passage: “The scientific community has never established that coercive interrogation methods are an effective means of obtaining reliable intelligence information. In essence, there seems to be an unsubstantiated assumption that ‘compliance’ carries the same connotation as ‘meaningful cooperation.’ ” In other words, waterboard someone or smack his head against the wall, and sure enough, he’ll open up and talk. But does that mean you’ll get reliable info that you couldn’t have gotten using more conventional techniques? Absolutely not. Dick Cheney insisted that two CIA analytical reports (that he apparently pressed to have prepared) concluded that his torture techniques rendered positive results. But these reports were declassified and published, and lo, they don’t say what he claimed they do.
Now another important contribution to the scientific literature has appeared. Irish neurobiologist Shane O’Mara of Trinity College Dublin, writing in Trends in Cognitive Sciences, takes a special look at the Bush Administration’s enhanced interrogation techniques:the use of such techniques appears motivated by a folk psychology that is demonstrably incorrect. Solid scientific evidence on how repeated and extreme stress and pain affect memory and executive functions (such as planning or forming intentions) suggests these techniques are unlikely to do anything other than the opposite of that intended by coercive or ‘enhanced’ interrogation.
