Bryan Caplan’s The Myth of the Rational Voter treats several immensely important and understudied topics—public ignorance of economics, political ideology, and their connection to policy error—from an orthodox economic perspective whose applicability to these topics is overwhelmingly disproven by the available evidence. Moreover, Caplan adds to the traditional and largely irrelevant orthodox economic notion of rational public ignorance the claim that when voters favor counterproductive economic policies, they do so deliberately, i.e., knowingly. This leads him to assume (without any evidence) (...) that “emotion or ideology” explain mass economic error. Straightforward, unchosen mass ignorance of economic principles—neither “rational” nor “irrational,” but simply mistaken—is a more coherent explanation for economic error, and it is backed up by the vast body of public‐opinion research.

Markets can be said to overcome ignorance in two senses. First, in an imaginary world of economic equilibrium, market prices can signal to consumers how they may alter their behavior so as to conform to supply and demand conditions of which they are ignorant. This is a point that was underscored by F.A. Hayek and, now, by Jeffrey Friedman. But the more important manner in which markets overcome ignorance was identified by Hayek's mentor, Ludwig von Mises, and is not mentioned (...) by Friedman: when market prices are not perfectly aligned to supply and demand conditions (and they never are), they present profit opportunities to entrepreneurs who are alert to make such discoveries. Their profit‐motivated actions then reallocate resources in a pattern more efficiently reflecting the true supply and demand conditions. It is this way of overcoming ignorance that most clearly separates the market arena from the political arena, because no corresponding corrective discovery process exists in politics. (shrink)

F. A. Hayek's realistic economic theory has been replaced by the formalistic use of equlibrium models that bear little resemblance to reality. These models are as serviceable to the right as to the left: they allow the economist either to condemn capitalism for failing to measure up to the model of perfect competition, or to praise capitalism as a utopia of perfect knowledge and rational expectations. Hayek, by contrast, used equilibrium to show that while capitalism is not perfect, it contains (...) error‐correcting institutions that bring it closer to perfection than is intuitively apparent.

Abstract If voters do not understand the programs of rival candidates or their likely consequences, they cannot rationally exercise control over government. An ignorant electorate cannot achieve true democratic control over public policy. The immense size and scope of modern government makes it virtually impossible for voters to acquire sufficient knowledge to exercise such control. The problem is exacerbated by voters? strong incentive to be ?rationally ignorant? of politics. This danger to democracy cannot readily be circumvented through ?shortcut? methods of (...) economizing on voter knowledge costs. A truly democratic government must, therefore, be strictly limited in scope. (shrink)

Bryan Caplan’s The Myth of the Rational Voter turns, in two contrasting ways, on the role of experts. On the one hand, Caplan uses the opinions of economists as a benchmark for identifying error in public opinion, finding such error systematic and pervasive. On the other hand, in considering remedies, he largely discounts the ability of policymakers to use expert advice and their own expertise to resist misguided public pressure. Although Caplan’s use of expert opinion as a benchmark, in principle, (...) is acceptable, he overstates what we can conclude from that exercise with his data. There are, however, alternative grounds for a more tentative, yet broadly similar, assessment of the prevalence of error in mass opinion. (shrink)
