Bryan Caplan

The Myth of the Rational Voter: Why Democracies Choose Bad Policies, published in 2007, further develops the "rational irrationality" concept from Caplan's earlier academic writing. It draws heavily from the Survey of Americans and Economists on the Economy in making the argument that voters have systematically biased beliefs about many important economic topics. Caplan writes that rational irrationality is an explanation for the failure of democracy.[10] The book was reviewed in the popular press, including The Wall Street Journal,[11] The New York Times,[12] and The New Yorker,[7] as well as in academic publications such as the Journal of Libertarian Studies,[13] Public Choice,[14] Libertarian Papers,[15] and The Independent Review.[16] It received a disparaging critique by Rupert Read in the European Review.[17]

In 2011, Caplan published his second book, titled Selfish Reasons to Have More Kids, arguing that people often work too hard in child-rearing, and as a result, they are scared of the idea of having children. Caplan's book urged parents to relax with respect to child-rearing. The book argues that as the perceived costs (in terms of child-rearing expense and effort) of having children fell, it made sense to have more children based on the basic theory of supply and demand.[18] The book was reviewed in The Wall Street Journal,[19] The Guardian,[20] RealClearMarkets,[21] and The Washington Times.[22] It also led to debates sponsored by The Wall Street Journal[23] and The Guardian.[24] The Guardian had Caplan debating "Tiger Mom" Amy Chua on the merits of strict parenting style.[24] The book was also featured in a story on National Public Radio.[25] Kirkus Reviews described it as "inconsistent and unpersuasive."[26]

The Case Against Education: Why the Education System Is a Waste of Time and Money, was published in 2018 by Princeton University Press. Drawing on the economic concept of job market signaling and research in educational psychology, the book argues that much of higher education is very inefficient and has only a small effect in improving human capital, contrary to much of the conventional consensus in labor economics that Caplan claims takes the human capital theory for granted.

Caplan and Saturday Morning Breakfast Cereal cartoonist Zach Weinersmith created the graphic non-fiction book Open Borders: The Science and Ethics of Immigration, which was released on October 29, 2019.[27]

Tyler Cowen called it "a landmark in economic education, how to present economic ideas, and the integration of economic analysis and graphic visuals." The Economist praised it as "a model of respectful, persuasive argument".[28]

Kevin D. Williamson concluded a review of the book with "But Professor Caplan’s argument is multifaceted, energetically presented, fun to read, and worth giving some real attention to if only as an exercise in clarifying one’s own thinking about the question".[29]

Caplan was cited as one of the leading proponents of the open borders position in articles in The Atlantic and Vox.[30][31] He has also been quoted on the topic of immigration in outlets such as the Huffington Post[32] and Time magazine.[33]

Caplan published a paper in Cato Journal titled "Why Should We Restrict Immigration?", where he made the moral and economic case for open borders while addressing various objections to his stance with practical solutions.[34] His views are more fully developed in the graphic non-fiction book, Open Borders: The Science and Ethics of Immigration.[35]

Caplan's anarcho-capitalist views were discussed by Brian Doherty in his book Radicals for Capitalism and in Reason magazine.[36] Caplan has claimed that anarcho-capitalists have a better claim on the history of anarchist thought than mainstream anarchists, or "left-anarchists", as he refers to them.[37][38] Because of this, Caplan has criticized one of the most notable examples of an anarchist-inspired society, Revolutionary Catalonia during the Spanish Civil War, in an essay entitled "The Anarcho-Statists of Spain."[39]

After having shed a youthful infatuation with the works of Russian American writer Ayn Rand and her philosophical system of Objectivism, in 2004, Caplan wrote in his essay "An Intellectual Biography", "I rejected Christianity because I determined that it was, to be blunt, idiotic. I rejected Objectivism and Austrianism, in contrast, as mixtures of deep truths and unfortunate mistakes. Let me begin with the deep truths. The Objectivists were right to insist that reality is objective, human reason able to grasp it, and scepticism without merit. They correctly hold that humans have free will, morality is objective, and the pursuit of self-interest typically morally right". He lists Michael Huemer as an influence in steering him away from Objectivism.[40]

In his essay "Atlas Shrugged and Public Choice: The Obvious Parallels", Caplan lauds Ayn Rand's Atlas Shrugged as making "an important contribution to social science."[41]
