In the most recent edition of The New Yorker, Atul Gawande has an absorbing article titled “Hellhole,” in which he reviews the effects of extreme isolation on the human mind. In particular, his article focuses on prisoners in America’s SuperMax facilities that spend upwards of 23 hours a day in solitary confinement. He also uses as examples, prisoners of war/hostages such as Terry Anderson and John McCain (who were isolated as a form of torture). American prisons purportedly use solitary confinement as a last ditch deterrent against the “worst of the worst”: that segment of the prison population which continues to commit crimes inside of the prison, gives the guards a hard time, or has successfully escaped previously. The problem is that the data shows that this approach simply doesn’t work. What’s more, it is as bad as any form of torture in that it irreversibly destroys the human brain:

Craig Haney, a psychology professor at the University of California at Santa Cruz, received rare permission to study a hundred randomly selected inmates at California’s Pelican Bay supermax, and noted a number of phenomena. First, after months or years of complete isolation, many prisoners “begin to lose the ability to initiate behavior of any kind–to organize their own lives around activity and purpose,” he writes. “Chronic apathy, lethargy, depression, and despair often result. . . . In extreme cases, prisoners may literally stop behaving,” becoming essentially catatonic.

Second, almost ninety per cent of these prisoners had difficulties with “irrational anger,” compared with just three per cent of prisoners in the general population. Haney attributed this to the extreme restriction, the totality of control, and the extended absence of any opportunity for happiness or joy. Many prisoners in solitary become consumed with revenge fantasies.

…EEG studies going back to the nineteen-sixties have shown diffuse slowing of brain waves in prisoners after a week or more of solitary confinement. In 1992, fifty-seven prisoners of war, released after an average of six months in detention camps in the former Yugoslavia, were examined using EEG-like tests. The recordings revealed brain abnormalities months afterward; the most severe were found in prisoners who had endured either head trauma sufficient to render them unconscious or, yes, solitary confinement. Without sustained social interaction, the human brain may become as impaired as one that has incurred a traumatic injury. [Link]

I find that last sentence particularly important given our modern culture of incessant Twittering and Facebook updates. If you think the reaction of the brain to social deprivation is bad now, just wait until you see the next generation of prisoners who not only have their friends and family but also their Twitter circle stripped from them. The most disturbing observation that Gawande makes is that none of this is a revelation. On the scientific front, Harry Harlow and his cruel experiments proved in the 1950s what harm isolation causes in monkeys. On the legal front, the U.S. Supreme Court opined in 1890 that solitary was no way to re-habilitate a criminal mind:

Justice Samuel Miller noted… “serious objections” to solitary confinement:

A considerable number of the prisoners fell, after even a short confinement, into a semi-fatuous condition, from which it was next to impossible to arouse them, and others became violently insane; others, still, committed suicide; while those who stood the ordeal better were not generally reformed, and in most cases did not recover sufficient mental activity to be of any subsequent service to the community.
