Abstract

The main thesis of this paper is that science denialism brings about an aberrant form of enquiry in which the epistemic norms governing scientific enquiry are deviated in significant ways. Science denialism doesn’t involve just a rejection of a scientific theory; it also deeply challenges the practice, common within scientific enquiry, of continuously and, to a certain extent, impartially testing research methods, theories, and evidential sources with the aim of improving the accuracy of our theories. We will offer an in-depth analysis of the epistemic mechanisms underpinning the normative aberration brought about by science denialism. More specifically, we will develop a fine-grained framework to model a variety of normative deviances that may take place in enquiry. By analysing two case studies, we will argue that fake news contributes significantly to shape the epistemic norms operating within science denialism. They in fact play two pivotal roles: first, they are used to cast discredit on a variety of (institutional) sources of evidence in relation to a certain set of phenomena (e.g. whether vaccines are safe for our health); second, they also play a part in building the alternative explanation of the targeted phenomena.
