ABSTRACT
Educated people must know how to make up their mind intelligently. When they have a decision to make, like which career to pursue, or who to vote for, or what to do with their company's assets, they weigh the pros and cons in a balanced, reasonable way. If they have a question of fact to resolve, like whether the stock market will go up or down, or who stole the cookies, they weigh the evidence fairly. The better they can perform these tasks, the better off they, and society at large, are in a number of ways.
