It seems, then, that thinking about time has the opposite effect on people from thinking about money. It makes them more honest than normal, rather than less so. Moreover, the more reflective they are, the more honest they become. Rewarding people with time instead of with money makes them "better" people... There must be an aphorism in that. Is this some unknown reason why we have prisons, one place where this takes place, to make people into better people?
