Misperceptions in a post-truth world: Effects of subjectivism and cultural relativism on bullshit receptivity and conspiracist ideation

This research investigated whether belief in truth relativism yields higher receptivity to misinformation. Two studies with representative samples from Sweden (Study 1, N = 1005) and the UK (Study 2, N = 417) disentangled two forms of truth relativism: subjectivism (truth is relative to subjective intuitions) and cultural relativism (truth is relative to cultural context). In Study 1, subjectivism was more strongly associated with receptivity to pseudo-profound bullshit and conspiracy theories than cultural relativism was. In Study 2 (preregistered), subjectivism predicted higher receptivity to both forms of misinformation over and above effects of analytical and actively open-minded thinking, profoundness receptivity, ideology, and demographics; the unique effects of cultural relativism were in the opposite direction (Study 1) or non-significant (Study 2).
