Science denial as a form of pseudoscience

Science denialism poses a serious threat to human health and the long-term sustainability of human civilization. Although it has recently been rather extensively discussed, this discussion has rarely been connected to the extensive literature on pseudoscience and the science-pseudoscience demarcation. This contribution argues that science denialism should be seen as one of the two major forms of pseudoscience, alongside of pseudotheory promotion. A detailed comparison is made between three prominent forms of science denialism, namely relativity theory denialism, evolution denialism, and climate science denialism. Several characteristics are identified that distinguish science denialism from other forms of pseudoscience, in particular its persistent fabrication of fake controversies, the extraordinary male dominance among its activists, and its strong connection with various forms of right-wing politics. It is argued that the scientific response to science denialism has to be conceived with these characteristics in mind. In particular, it is important to expose the fabricated fake controversies for what they are and to reveal how science denialists consistently use deviant criteria of assent to distort the scientific process.
