Prisoners should be measured. The same way that some companies have performance measurements for its employees, prisons should have behavioural measurement for the prisoners. If the behaviour improves based on a certain grade, then the prisoners get rewarded, otherwise they get punished
How about measuring the prison instead, reform more crooks, the guards get a pay bonus. However, knowing how incentive schemes are normally gamed, they will probably resort to lobotomising the inmates.
