People tend to think the world is much worse off than it actually is. Bad news gets a lot more attention than good news. Professor Bryan Caplan calls this “Pessimistic Bias,” and argues that it affects the policies people vote for. Despite the amazing economic gains of the past 100 years and even the past decade, most people are under the impression that things are just getting worse. But Prof. Caplan argues that even with all the tough problems in the world, there is reason for optimism; contrary to most people’s expectations, he contends that the best is yet to come.
