It’s a question that we should ask more of everyone. Research suggests rationality can be improved with training – especially those who seek political power. It’s certainly apparent the human species needs some training in rationality. Intelligence seems to be baked into each of us. There’s not much room to gain IQ points over a lifetime. Ideally, education serves to equalize the difference between large populations of people by providing, among other things, critical thinking and reasoning skills. In the U.S., this project seems to have failed for the most part. Turns out, highly intelligent people are just as susceptible to cognitive bias as the rest of us. Hence the need for rationality.
