On the Imposition of Torture, an Extreme Stressor State, to Extract Information From Memory

A Baleful Consequence of Folk Cognitive Neurobiology

There is a widespread and popularly-held belief that the imposition of extreme stressor states (torture) is efficacious at facilitating the release of intentionally-withheld information from (human) memory. Here, I explore why this belief is so widespread. I examine the folk model of the brain and behavior that underpins this belief, and show that this folk model is utterly inconsistent with what we currently know about the effects of extreme stressor states on the brain systems that support memory and executive function. Scientific evidence on how repeated and extreme stress and pain affect memory and executive functions (such as planning or forming intentions) suggests that subjecting individuals to such states is unlikely to do anything other than the opposite of what is intended by coercive or “enhanced” interrogation. Coercive interrogations involving imposition of extreme stressor states are unlikely to facilitate the release of veridical information from long-term memory, given our current cognitive neurobiological knowledge. On the contrary, these techniques cause severe, repeated, and prolonged stress, which compromises brain tissue supporting memory and executive function. The fact that the detrimental effects of these techniques on the brain are not visible to the naked eye makes them no less real.
