You are correct, I have worked in corrections and even a relatively brief stay in solitary can have a very detrimental effect.
One reason I believe, is that your usual criminal is ill equipped for introspection or penitence. Placed in solitary he is completely without the inner resources to both deal with it or benefit from it.
Excellent observation and very true.
It seems ALL people have a need for social interaction, and the deprivation of that is akin to depriving a person of food, only slower and ‘only’ resulting in insanity.
Insightful. One more insight please - the press never reports on extrovert criminals - the only time we hear of a personality trait is when the extroverts in the press gush over the fact that a given criminal was a 'loner'. They never report on criminals who hang out in bars with friends etc... What's your take - introvert to extrovert - who fills the prisons?
