Terence Kealey argues that we don’t need public funding for science. Not only are many of the common historical examples of the benefits of public funding false, the economic model of publicly funded scientific research is fundamentally flawed. Empirically, public R&D appears to have a negligible effect on economic growth. Private science is likely to be more responsive to consumers’ needs, and the costs of duplicating it are often high enough that we need not worry about free riders on the discoveries of others.

Victoria Harden offers several historical examples of successful funding for public health initiatives. These programs, including the prevention of cholera, basic research on chemical warfare agents and cancer, and the identification of the virus that causes AIDS, might conceivably have happened under purely private auspices. But she finds it implausible that private actors would have responded as quickly or effectively.

Patrick J. Michaels discusses the public choice aspects of scientific funding, which introduce systematic bias into research: Scientists need grant money to advance in their careers, and only the government provides it in sufficient quantities. Yet the government’s agenda is never neutral, and the scientists’ agendas tend strongly to fall into line. The result is a consensus built not on scientific fact, but on the alignment of personal interests.

David Guston rejects the public goods argument for scientific research. He nonetheless argues that it is essential for any government to conduct such research. Governments are constantly called upon to regulate and adjudicate disputes among scientifically and technologically savvy actors. They are obliged to make laws that take into account scientific laws. Indeed, no one would want to live under a state that predictably failed in these respects.
