I believe that we all get rewarded and punished according to whether we operate in harmony or in conflict with nature's laws, and that all societies will succeed or fail in the degrees that they operate consistently with these laws.

I believe that understanding what is good is obtained by looking at the way the world works and figuring out how to operate in harmony with it to help it evolve.

One of the greatest sources of problems in our society arises from people having loads of wrong theories in their heads - often theories that are critical of others - that they won't test by speaking to the relevant people about them. Instead, they talk behind people's backs, which leads to pervasive misinformation.

What matters most is that the people you work with share your values.

Demand is best measured in terms of spending. You know, I think in traditional economics, it's a mistake to measure it in terms of the quantity of goods.

I'm sure Donald Trump will think that he has the truth, and some journalist is arguing that he has truth, and somebody else is arguing that they have the truth. And in fact it's even worse than that because they're so hell bent on their arguments that they will distort the truth consciously. They'll manipulate the facts to support their arguments because they're so hung up in the fight. That's where the problem is, so we argue all the time.

Don't be a perfectionist, because perfectionists often spend too much time on little differences at the margins at the expense of other big, important things. Be an effective imperfectionist. Solutions that broadly work well (e.g., how people should contact each other in the event of crises) are generally better than highly specialized solutions (e.g., how each person should contact each other in the event of every conceivable crisis).
