"Every established proposition of science enters into the current premises of science and affects the scientist's decision to accept an observation as a fact or to disregard it as probably unsound... this material (I present) refutes the widely held view that scientists necessarily abandon a scientific proposition if a new observation conflicts with it."
-- Michael Polanyi, Science, Faith, and Society
Folks, "Popperian" "falsificationsism" has been "falsified" by the works of Polanyi, Toulmin, Lakatos, Kuhn, and many others. It is currently only embraced by amateurs in the philosophy of science who are unwilling to engage with the extensive literature refuting Popper's views. My libertarian friends who continue to endorse this well-refuted understanding of science risk discrediting libertarianism by unnecessarily linking it to antiquated views.
