I'm not sure fucking around with someone's brain is the way to go. Nor do I think 0% recidivism is possible, short of just burying every criminal. However, lowering the recidivism rate is a noble goal. To that end, might I suggest:
1. Eliminate prisons for profit.
2. Prison should become a rehabilitation center. Job skills, health care (mental health), positive environment, etc. No more crime schools. Definitely do the time of the crime, but also have a positive exit strategy to rejoin society.
3. Non-violent crimes not showing up on background checks.
Those three things would dramatically change how many people return to the prison system.
(This of course after we fix the educational system in the United States)
