Pluralistic ignorance
In social psychology, pluralistic ignorance is a situation in which a majority of group members privately reject a norm, but go along with it because they incorrectly assume that most others accept it. This is also described as "no one believes, but everyone thinks that everyone believes". In short, pluralistic ignorance is a bias about a social group, held by the members of that social group.
Counterknowledge
Thompson argues that we are experiencing a "pandemic of credulous thinking". People are increasingly surrendering the values of the Enlightenment to accept a barrage of "counterknowledge", which he defines as "misinformation packaged to look like fact". This concept embodies both theories for which there is no supporting evidence, and theories against which there is already evidence that directly contradicts them. Thompson does not consider religious teachings to be counterknowledge because their claims are metaphysical, and are thus inherently unverifiable.
