Abstract

This preregistered study validated the English version of the Pseudoscience Endorsement Scale (PES) and investigated its correlates. 510 U.S. volunteers completed the PES, questionnaires measuring paranormal, denialist, and conspiracist beliefs, a scientific literacy questionnaire, a bullshit detection test, and a cognitive reflection test. The validation resulted in a shorter version (sPES). Scores on different unwarranted belief questionnaires correlated, suggesting a common basis. Scientific knowledge, cognitive reflection, and bullshit sensitivity negatively associated with sPES scores, with bullshit receptivity being the main predictor of pseudoscience endorsement.
