There is much evidence that people are not rational, in the economist’s sense; nor do they take into account expectation, in the precise interpretation of that word. As a result economic theory often does not correspond with what happens in the market. Some would argue that we need descriptive economics. I would argue that all should be taught about probability, utility, and MEU (maximization of expected utility) and act accordingly.

Kenneth E. Boulding was a most extraordinary economist. The narrow bounds of the economics discipline could not contain his interests and talents. In addition to economics, Professor Boulding made important contributions to the fields of political science, sociology, philosophy, and social psychology. His forays into subjects outside the usual concerns of economists were not an intellectual dilettantism; rather, they were a result of his conviction that an understanding of human behavior can only be accomplished by studying man in his totality. Much of Boulding's work was an attempt to move beyond the narrow economic view of humans as self-interested, rational utility maximizers to a general social science exploiting the full range of our rational, instinctual, and mystical knowledge.

How many people ruin themselves by laying out money on trinkets of frivolous utility? What pleases these lovers of toys is not so much the utility, as the aptness of the machines which are fitted to promote it. All their pockets are stuffed with little conveniences. They contrive new pockets, unknown in the clothes of other people, in order to carry a greater number. They walk about loaded with a multitude of baubles, in weight and sometimes in value not inferior to an ordinary Jew's-box, some of which may sometimes be of some little use, but all of which might at all times be very well spared, and of which the whole utility is certainly not worth the fatigue of bearing the burden.

 

Adam Smith

 

Take the Kyoto Protocol. Destruction of the environment is not only rational; it's exactly what you're taught to do in college. If you take an economics or a political science course, you're taught that humans are supposed to be rational wealth accumulators, each acting as an individual to maximize his own wealth in the market. The market is regarded as democratic because everybody has a vote. Of course, some have more votes than others because your votes depend on the number of dollars you have, but everybody participates and therefore it's called democratic. Well, suppose that we believe what we are taught. It follows that if there are dollars to be made, you destroy the environment. The reason is elementary. The people who are going to be harmed by this are your grandchildren, and they don't have any votes in the market. Their interests are worth zero. Anybody that pays attention to their grandchildren's interests is being irrational, because what you're supposed to do is maximize your own interests, measured by wealth, right now. Nothing else matters. So destroying the environment and militarizing outer space are rational policies, but within a framework of institutional lunacy. If you accept the institutional lunacy, then the policies are rational.

 

Noam Chomsky

 

Those who invalidate reason, ought seriously to consider, "whether they argue against reason, with or without reason; if with reason, then they establish the principle, that they are laboring to dethrone;" but if they argue without reason, (which, in order to be consistent with themselves, they must do,) they are out of the reach of rational conviction, nor do they deserve a rational argument.

 

Ethan Allen

 

Even though principles of rationality seem as often violated as followed, we still cling to the notion that human thought should be rational, logical, and orderly. Much of law is based upon the concept of rational thought and behavior. Much of economic theory is based upon the model of the rational human who attempts to optimize personal benefit, utility, or comfort. Many scientists who study artificial intelligence use the mathematics of formal logic—the predicate calculus—as their major tool to simulate thought. [...] Human thought is not like logic; it is fundamentally different in kind and spirit. The difference is neither worse nor better. But it is the difference that leads to creative discovery and to great robustness of behavior.
