In any case, here's Atul Gawande's examination of whether or not solitary confinement is torture. The short answer to that question: probably yes.
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 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.
There are solutions to this. Take the British approach, for example:
The approach starts with the simple observation that prisoners who are unmanageable in one setting often behave perfectly reasonably in another. This suggested that violence might, to a critical extent, be a function of the conditions of incarceration. The British noticed that problem prisoners were usually people for whom avoiding humiliation and saving face were fundamental and instinctive. When conditions maximized humiliation and confrontation, every interaction escalated into a trial of strength. Violence became a predictable consequence.
So the British decided to give their most dangerous prisoners more control, rather than less. They reduced isolation and offered them opportunities for work, education, and special programming to increase social ties and skills...The results have been impressive. The use of long-term isolation in England is now negligible. In all of England, there are now fewer prisoners in “extreme custody” than there are in the state of Maine. And the other countries of Europe have, with a similar focus on small units and violence prevention, achieved a similar outcome.
Of course, the U.S. would never allow such vast sweeping reforms. Our toxic political system paradoxically requires all politicians to be tough on criminals without actually examining the root causes of criminality and negative behavior in prisons. It's a can't-miss recipe to continue upon the horrible path we're on.
