 The most prominent difference between pseudo-theory promotion and science denial is their different attitudes to conflicts with established science. Science denialism usually proceeds by producing false controversies with legitimate science, i.e. claims that there is a scientific controversy when there is in fact none. This is an old strategy, applied already in the 1930s by relativity theory deniers (Wazeck 2009, 268–269). It has been much used by tobacco disease deniers sponsored by the tobacco industry (Oreskes and Conway 2010; Dunlap and Jacques 2013), and it is currently employed by climate science denialists (Boykoff and Boykoff 2004; Boykoff 2008). However, whereas the fabrication of fake controversies is a standard tool in science denial, it is seldom if ever used in pseudo-theory promotion. To the contrary, advocates of pseudosciences such as astrology and homeopathy tend to describe their theories as conformable to mainstream science.
