If Science Is a Public Good, Why Do Scientists Own It?

I argue that if science is to be a public good, it must be made one. Neither science nor any other form of knowledge is naturally a public good. And given the history of science policy in the twentieth century, it would be reasonable to conclude that science is in fact what economists call a ‘club good’. I discuss this matter in detail in two contexts: (1) current UK efforts to create a version of the US DARPA that would focus on projects of larger, long-term societal interests – i.e. beyond the interests of the academic specialities represented in, say, the US NSF; (2) what I call the ‘organized hypocrisy’ involved in presenting science as a public good through the so-called ‘peer review’ process.
