I trust evolution.
I trust evolution to do what is in evolution's interest. Incentives, after all. Just need to figure out how to incentivize evolution to behave nicely.
Wisdom: 100% from concentrate
Incentives are EVERYTHING; people need to understand that they cannot assume everyone (most others) to be truthful and that if they align incentives in a game-theoretical setting everyone (each and all) is better off, with the exception of the parasites and the myopic, who are better off in a system that is so easy to game
Incentives are everything, but keep in mind that there is no such thing as cheating with natural selection. Genghis Khan's gene propagation strategy was successful as was the sperm bank donor with thousands of offspring. Civilization is an attempt at UNnatural selection. "Behaving nicely" is a completely relative concept.
