I think my comment was more academic than pragmatic: Once you let go of the assumption that people will invariably do bad things in the absence of external control, the whole model falls apart. As for practical recommendations, I've seen very few come out of academic research, unfortunately. From SIDE you could derive that you should aim to create a community or an idea that people identify with in a positive way (thus creating a social identity), and try to facilitate the salience of that identity by adjusting the situational setting.
