Pseudoscience: Objective or Subjective? MICHAEL RUSE ABSTRACT WORK TYPE What is pseudo–science and when do charges of pseudo–scientific thinking Article generally arise? These questions are answered by looking at six examples where the charge of pseudo–science has arisen: anti–vaccination and the ARTICLE HISTORY claims that it causes illnesses, Creationism – the claim that the Bible is Received: literally true –, chiropractic and claims about curing cancer and the like, pre– 19–May–2019 Darwinian evolution, that is developmental hypotheses before the Origin of Accepted: Species (1859), Immanuel Velikovsky and his book, Worlds in Collision, and 14–July–2019 the Gaia hypothesis that the Earth is an organism. It is agreed that there is an Published Online: objective foundation to charges of pseudo–science and the author’s 24–November–2019 testimony in a court case in Arkansas in 1981, arguing that Creationism is not genuine science, is used to support this claim. Karl Popper’s criterion of ARTICLE LANGUAGE demarcation invoking falsifiability is a key notion here. However, it is argued English that charges of pseudo–science occur most frequently when conventional practitioners are under threat. Then claims of pseudo–science are used to KEYWORDS attack the non–conventional opposition. The examples are used to support Pseudoscience this conclusion.
