They can consider other people. I would say, without any hestitation, that teaching thinking is by far the most imporrtant thing that can be taught in all prisons. By this I mean the CoRT programme and its 'tools' method. There is a lot of stuff out there on teaching thinking which is complex and has little effect. Quite apart from the teaching of thinking to prisoners, there is another project.
Prisoners have all the time in the world to think.
Given some training and some structure there could be a vast think tank of thousands of prisoners around the world.
