We are like a rider on top of a gigantic elephant. We can steer the elephant, and if he's not busy, he'll go where we want, but if he has other desires, he'll often go where he wants. How can one control the elephant? In part, this comes with maturity. In part, this comes with the development of your frontal cortex, so the frontal areas of the brain are especially involved in self-control, in suppressing your initial instinct to act. This is why teenagers are so impulsive. So it's terrible to allow the death penalty for teenagers, because they really don't have working brains yet.

I think that we Americans, in particular, tend to think too directly about problems. If there's a problem we want to basically go in with a screwdriver or else drop bombs on it. A better way to solve problems is to think indirectly and try to change the environment. So I think you can gain much better self-control not so much by working on yourself as by looking at the situations you're in and the people you hang around, and changing your environment.

Even if you have a brain predisposed to liberalism, you might end up with some conservative friends or find inspiring conservative role models who could be very influential on you, and that could send you down a different track in life.

We can tolerate great diversity in our aesthetic beliefs, but we can't tolerate much diversity in our moral beliefs.

The consistent finding of psychological research is that we are fairly accurate in our perceptions of others. It's our self-perceptions that are distorted because we look at ourselves in a rose-colored mirror.

Intuitions come first, strategic reasoning second.

Economic issues are just as much moral issues as social issues.
