Torture: does it work?

by endlesspsych

Much to the shame of our armed and security forces it appears we, like our American allies, have been involved in the torture of suspected terrorist or suspected insurgents. The Lib Dems foreign affairs spokesmen is one of many currently calling for a full enquiry into the sorry affair. You can see the full story on the BBC website.

Mr Davey said the number of allegations about the activities of British secret service agents and their complicity in torture “needed to be taken seriously”.

There was evidence that British agents had used information obtained through torture, questioned suspects knowing they had been torture and that British overseas territories had been involved in illegal transfer or “state kidnapping” of suspects.

Between 2002 and 2005, it believes government policy led to British agents being complicit in torture in breach of its international obligations and that then prime minster Tony Blair knew about this.

Amidst fears that there may be a cover up of sorts:

ministers had “deliberately and persistently” prevented the publication of materials which may provide evidence of this, not for national security reasons but to prevent its own embarrassment.

“The need to get to the truth about torture is about justice and about restoring the reputation of our intelligence services after they were so traduced by this government over Iraq,” Mr Davey said.

Mr Davey said ministers should not be allowed to “hide behind” the ongoing police investigations into a handful of alleged torture cases.

Whats interesting is, that unlike the American position that torture was the result of a few bad apples, the British position seems to be that something is rotten with the whole barrel not just a few overenthusiastic mavericks. Which perhaps implies a systemic failure leading to torture and brutality which requires closer introspection and examination then the dismissal of a few key players. I would encourage anyone who is remotely interested in this current torture scandal and the scandal of Abu Gharib to read Zimbardos “The Lucifer effect”: a summation of the famous Stanford prison experiment and an account of how Abu Gharib could have happened that criticises the system that allowed it to take place rather than the individual actors involved.

The report on the news seemed to suggest that the torture carried out was based on the CIA’s classic text of torture the KUBARK manual, stress positions, disorientation and the like all present and correct. In the interests of attempting to debunk the idea (sometimes presented as the common sense notion) that torture works it seems appropriate to look at the “research” which led to the techniques of modern torture contained within KUBARK being created and used.

To do that we have to look at the research of a number of psychologists and other scientists conducted during the Cold War from 1950 to 1962 under the heading MKUltra. Headed by Sidney Gottileb the project funded experiments into LSD and other drugs, hypnosis and “psychic driving“. With the goal of finding a way to control or influence the mind in a Manchurian candidate stylee…

Psychic driving was the precursor to Donald Ewan Camerons depatterning techniques on which much of the basic principles of KUBARK are founded. It was of particular interest to the CIA as it’s central concept was that it is possible to erase a persons mind and start again from scratch. Essentially by means of excessive use of electroconvulsive therapy and the drugging of “patients” to make them more susceptible to suggestion, then planting a suggestion in their minds that counteracted what was though to be the root of their neurosis. A random, and highly damaging, synergy of behaviorist ideas and Freudian flights of fancy which has now, unsurprisingly, been discredited. Much of these experiments were conducted without proper informed consent and damaged many, many lifes without providing any evidence that they worked whatsoever.

The patients in Camerons experiments, much like torture victims, did not become more malleable or prone to revealing information. They became confused, experienced memory problems and in many cases seemed to “regress” to a childlike state. None of which sounds like it would be particularly conducive to gathering reliable information. Although even if they were not confused or didn’t suffer memory problems the very basis of techniques based on Camerons depatterning involves increasing suggestibility. Again something I contend that’s not conducive to gathering effective and reliable intelligence.

It is my contention that torture hasn’t moved on all that much since KUBARK first came into existence. For one thing it would be very difficult to fund research on any great scale into methods of torture and its efficacy in the modern age, I find it hard to imagine someone wouldn’t find out in a manner similar to that Abu Gharib was exposed. Scientists have also contended that the use of torture as understood by “folk psychology” (if I hit you and keep hitting you, you are more likely to tell me what I want to know to make me stop) is also unlikely to work.

Neurobiologist Shane O’Mara of the Trinity College Institute of Neuroscience in Dublin explains in a paper in the journal Trends in Cognitive Sciencecalled “Torturing the Brain,” “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.”

Extreme pain and stress has been shown in many, many situations to have the opposite effect to that which interrogators wish. Yes they may “soften up” the victim but also leave them in such a state that they cannot effectively respond to questioning accurately. As such I would suggest that the interogator will probably extract the information they wish but really they have no means of knowing if this information is actually true. Thats actually true in an objective real sense that it provides actionable intelligence not in some wishy washy post modern “there is no truth sense”.

Further to this looking at how information is recalled from the brain shows another reason why torture probably doesn’t work.

Fact One: To recall information stored in the brain, you must activate a number of areas, especially the prefrontal cortex (site of intentionality) and hippocampus (the door to long-term memory storage). Fact Two: Stress such as that caused by torture releases the hormone cortisol, which can impair cognitive function, including that of the prefrontal cortex and hippocampus. Studies in which soldiers were subjected to stress in the form of food and sleep deprivation have found that it impaired their ability to recall personal memories and information, as this 2006 study reported. “Studies of extreme stress with Special Forces Soldiers have found that recall of previously-learned information was impaired after stress occurred,” notes O’Mara. “Water-boarding in particular is an extreme stressor and has the potential to elicit widespread stress-induced changes in the brain.”

In fact it would probably be prudent to link to the source of this information and allow you to read it for yourself: An excellent Newsweek blog from Sharon Begley. I also recommend this wired article which covers similar ground.

A report published by the Intelligence Science Board in 2007 found that no research existed to support the use of enhanced interrogation. And O’Mara’s review, published Monday in Trends in Cognitive Science, describes a wealth of science that supports ending the practice.

O’Mara derides the belief that extreme stress produces reliable memory as “folk neurobiology” that “is utterly unsupported by scientific evidence.” The hippocampus and prefrontal cortex — the brain’s centers of memory processing, storage and retrieval — are profoundly altered by stress hormones. Keep the stress up long enough, and it will “result in compromised cognitive function and even tissue loss,” warping the minds that interrogators want to read.

What’s more, tortured suspects might not even realize when they’re lying. Frontal lobe damage can produce false memories: As torture is maintained for weeks or months or years, suspects may incorporate their captors’ allegations into their own version of reality.

I’d further argue that the principle of covergent evidence strongly suggests that torture does not in fact work. Indeed just by using the information contained in this report the idea that torture is effective in extracting accurrate and reliable evidence seems to be built on shaky ground:

Pain and Physical Discomfort

This suggests that physical torture may not have an effect:

Reports about the treatment of POWs and foreign prisoners in China documented the use of physical abuse, but studies of the role of assault in promoting attitude change and in eliciting false confessions (even from U.S. servicemen) revealed that it was ineffective. Belief change and compliance was more likely when physical abuse was minimal or absent (Biderman 1960).

Sleep Loss/Deprivation
Sleep loss/deprivation is associated with:

• General cognitive slowing (Dinges and Kribbs, 1991)
• Impaired attention (Hockey, 1970; Norton, 1970)
• Diminished concentration (Williams, Lubin, and Goodnow, 1959)
• Impairment in cognitive functions associated with right anterior
hemisphere or subcortical areas such as motor, rhythm, receptive and
expressive speech, memory, and complex verbal arithmetic functions
(Kim et al., 2001)
• Impaired decisionmaking involving the unexpected, innovation,
revising plans, competing distractions, and effective communication
(Harrison and Horne, 2000)
• Reduced capacity for logical and sequential thought (Blagrove,
Alexander, and Horne, 1995; Horne, 1988b; Williams and Lubin, 1967)
• Decreased accuracy in time estimation, and both immediate and
delayed recall (Taylor and McFatter, 2003)
• Negative effects on mood (Lieberman et al., 2002)
• Alteration of the body’s immune system (Everson, 1997)
• Increased perception of physical pain (hyperalgesia) (Kundermann et
al., 2004)
• Decreased motivation (Wilkinson, 1961, 1964; Horne and Pettitt, 1985;
Meddis, 1977)
Increased suggestibility (Blagrove, Cole-Morgan, and Lambe, 1994;
Blagrove, 1996).

Many of which implie that sleep deprivation is not much use as a means of obtaining information (being prone to suggestibility in particular, as well as reduced capacity for logical and sequential thought)

On this last point it is worth noting that suggestibility increases specifically under conditions simulating an interrogation. At least one study has found that “the effect on suggestibility of one or two night’s sleep loss is comparable to the difference in suggestibility between true and false confessors.” (Blagrove, 1996)

Sensory deprivation
is associated with:

• Impairment in higher mental functions and complex intellectual tasks
(Myers, Murphy, Smith, and Goffard, 1966; Kitamura, 1967)
• Increased susceptibility to infl uence (under some conditions) (Myers et
al., 1966)
Heightened hypnotic susceptibility (Sanders and Reyher, 1969)
• Diminished EEG activity correlated with apathetic, lethargic behavior,
and a reduction in stimulation seeking behavior (Scott and Gendreau,
• Behaving in a way that is more boring and unlikable (Zuckerman et al.,
Increased anxiety and depression (Zuckerman et al., 1970)
• Greater instability of beliefs and of both peripheral and central attitudes
(Tetlock and Seudfeld, 1976; Seudfeld and Borrie, 1978)
• Cognitive disorganization (Seudfeld and Borrie, 1978)
Increased persuadability (Seudfeld and Borrie, 1978)
Increased compliance behavior (beyond usual social infl uence
conditions) (Moscovici and Doms, 1982)

Two papers from the journal of Biological Psychiatry also seem to back up the views that battlefield stress (which I contend makes a good proxy for torture in the sense it’s  stress caused by the fear that death could arise at any minute and a poor proxy because there is a greater degree of control then found in a torture scenario):
Stress-Induced Deficits in Working Memory and Visuo-Constructive Abilities in Special Operations Soldiers
Severe decrements in cognition function and mood induced by sleep loss, heat, dehydration, and undernutrition during simulated combat

Interestingly the second study deals with the effects of high levels of stress experienced during simulated combat… I reckon this shows that just because it is unethical to study something directly does not imply you can not study a lesser or similar experience to gain insight…

Despite all the evidence, that I contend shows torture doesn’t actually work as a means of extracting reliable information, some will still contend that “the ticking time bomb scenario” still mitigates it’s use.

The ticking time bomb scenario is a thought experiment that has been used in the ethics debate over whether torture can ever be justified.

Simply stated, the consequentialist argument is that nations, even those such as the United States that legally disallow torture, can justify its use if they have a terrorist in custody who possesses critical knowledge, such as the location of a time bomb or a weapon of mass destruction that will soon explode and cause great loss of life.

Martin, of the layscientist blog, has given a good account of some of the issues with the assumptions underlying accepting torture under this scenario over on liberal conspiracy.

The strongest argument in favour of torture is the so called ‘ticking bomb’ scenaro. Alan Dershowitz gave a good summary of it in the San Francisco Chronicle back in 2001:

“Everybody says they’re opposed to torture. But everyone would do it personally if they knew it could save the life of a kidnapped child who had only two hours of oxygen left before death. And it would be the right thing to do.”

It’s a compelling argument, until you start to look at the assumptions that you have to make to accept it. This argument assumes that you have the right person in custody, it assumes that this person actually has the information you need, it assumes that there isn’t a better way of getting hold of the evidence, and above all it assumes that torture is an effective way of getting that information.

Yet this misses one crucial problem with the ticking timebomb scenario… In that there is no method of extracting information that falls under the umbrella of torture that doesn’t require quite some time to carry out. Indeed torture methods rely on keeping people in stress positions or isolation for hours on end… so unless the bomb has quite a long fuse torture, as it is currently practiced under the auspices of KUBARK and it’s successors is useless.

There is a further reason to assume that, even despite evidence that seems to suggest the contrary, if torture does work it is not of benefit to a democratic country to make us of its techniques. As shown by the French battle for Algiers in the 1950’s and a lesson we should have learnt from the Northen Ireland conflict in the 1970’s. Torture simply serves to further alienate the local population and turn them against you with more venom and more surety in your status as enemy. In short torture plays directly into the hands of terrorist recruiters.

As a former special intelligence operations officer notes:

“It’s extremely ineffective, and it’s counterproductive to what we’re trying to accomplish,” he told reporters. “When we torture somebody, it hardens their resolve,” Alexander explained. “The information that you get is unreliable … And even if you do get reliable information, you’re able to stop a terrorist attack, Al-Qaeda’s then going to use the fact that we torture people to recruit new members.” Alexander says torture techniques used in Iraq consistently failed to produce actionable intelligence and that methods outlined in the US Army Field Manual, which rest on confidence building, consistently worked and gave the interrogators access to critical information.

Indeed it seems we should be helping suspects from whom we wish to extract information rather than hurting them. Building up rapport and extracting information on the basis of the norms of reciprocity seems to be more effective. Although I an almost hear the cry go up now – there isn’t enough time! We need a quicker method! Well given how long it takes to depattern and subdue an individual terror suspect and this process makes it less, rather than more, likely that they will cooperate…

I’d suggest you can use torture if you want but that bombs just gonna keep on a ticking anyway…

In summation the answer to the question “does torture work?” is not a definite no but is a very strong “probably not”.
