 Epistemic relativism is a term with many meanings; the meaning most relevant in discussions on pseudoscience is denial of the common assumption that there is intersubjective truth in scientific matters, which scientists can and should try to approach. Epistemic relativists claim that (natural) science has no special claim to knowledge, but should be seen “as ordinary social constructions or as derived from interests, political-economic relations, class structure, socially defined constraints on discourse, styles of persuasion, and so on” (Buttel and Taylor 1992, 220). Such ideas have been promoted under different names, including “social constructivism”, the “strong programme”, “deconstructionism”, and “postmodernism”. The distinction between science and pseudoscience has no obvious role in epistemic relativism. Some academic epistemic relativists have actively contributed to the promotion of doctrines such as AIDS denial, vaccination denial, creationism, and climate science denial (Hansson 2020, Pennock 2010). However, the connection between epistemic relativism and pseudoscience is controversial. Some proponents of epistemic relativism have maintained that that relativism “is almost always more useful to the side with less scientific credibility or cognitive authority” (Scott et al. 1990, 490). Others have denied that epistemic relativism facilitates or encourages standpoints such as denial of anthropogenic climate change or other environmental problems (Burningham and Cooper 1999, 306).
