Prison is a hellish realm, where convicts struggle in a tooth-and-nail battle; everyone fights to get respect, and toughness wins prestige. The prison yard becomes a jungle where the powerful prevail and fear rules. It’s a psychopath’s paradise, where coolheaded cruelty wins the day… Survival there demands an amygdala that is set for paranoid hypervigilance, plus a protective emotional distance or outright distrust, and a readiness to fight… Prisons are colleges for criminal activity, strengthening an inmate’s predilection and skill sets for criminality. Younger prisoners make the very worst kind of connections in prison, typically becoming mentored by more seasoned inmates, so that on their release they are hardened, angry, and endowed with greater skills as criminals.
