Are these theoretical or have they been done in the real world? I have seen an endless procession of game-theoretic illustrations of nove problem solving techniques. In the real world the only technique I have seen work is "hey, you, stop shitting there or go to jail." The reason is that game-theoretic arenas are idealized computational worlds where all the rules and influences are known, while real environments are full of unknown perturbing factors not accounted for in the model. Don't get me wrong. I would love to see such a real world example, since I dislike authoritarianism. But I'm just not encouraged by what I see. I do know that telling people "things would be better for all of you if..." never works. People would rather suffer than change their behavior, even if a change in behavior is low-effort and brings about an increase in wealth or standard of living. I actually sometimes think the problem is that people are insufficiently greedy-- inertia and laziness is more powerful than desire. As evidence for my final cynical dictum I present: American eating habits. People would rather be miserable, fat, poisoned zombies than to stop eating empty carbs with a side of sugar and mystery meat. They choose the comfort of the known over a healthier, more alert, and longer existence.
