Knowledge and Decisions
Knowledge and Decisions is a nonfiction work authored by American economist Thomas Sowell, initially released in 1980 by Basic Books and later republished in 1996. In this book, Sowell explores the mechanisms through which social and economic knowledge circulates within society and how this influences decision-making processes. The principal focus on dispersed knowledge draws inspiration from F.A. Hayek's essay "The Use of Knowledge in Society." Hayek commended Sowell for elaborating on these ideas using practical economic illustrations.
Sowell critiques the tendency to interpret economic and political choices primarily through a moral lens, suggesting that such an approach neglects the unavoidable compromises and constraints present in any system. Consistent with his laissez-faire philosophy, he condemns price controls—such as rent control, minimum wage, price fixing, and subsidies—for interfering with the vital communication between consumers and producers that is necessary for optimal decision-making. He explains ongoing inefficiency or corruption within industries or government agencies not as the result of malicious actors but as rational responses by individuals to flawed incentive structures.
The concluding part of the book centers on intellectuals, defined as professionals who disseminate ideas. Sowell expresses skepticism towards uncritical reliance on experts and "articulated rationality" as remedies for economic or political challenges. He draws attention to the expanding influence of bodies like the United States Environmental Protection Agency and National Institutes of Health, which impose more regulations than Congress yet remain largely unaccountable due to their unelected status. This dynamic increases the disconnect between policymakers and those impacted by their decisions.
Additionally, Sowell discusses the frequent occurrence of unintended consequences stemming from intellectual interventions, advocating instead for decentralized decision-making frameworks that empower individuals economically rather than depending on centralized planning by unelected intellectual elites.
