A broad literature indicates that pathogen, sexual, and moral disgust sensitivity relate to, among other things, political attitudes, moral condemnation, and symptoms of psychopathology. As such, instruments measuring disgust sensitivity have been widely used across subfields of psychology. Yet, surprisingly little work has examined whether self-reports in disgust sensitivity reflect systematic trait variation. Here, we present the first study to examine self-other agreement in pathogen, sexual, and moral disgust sensitivity. Romantic partners (n1 = 290), friends (n2 = 212) and acquaintances (n3 = 140) rated each other on these three domains of disgust sensitivity and on the HEXACO personality dimensions. Correlations between dyad partners’ self- and other-ratings were calculated to estimate the magnitude of self-other agreement. We found self-other agreement in all domains of disgust sensitivity (r’s of .36, .46, and .66 for moral, pathogen, and sexual disgust sensitivity, respectively), with this agreement only slightly inferred from personality perceptions (percentages mediated by HEXACO were 15%, 7%, and 33% for pathogen, sexual, and moral disgust sensitivity, respectively). These results suggest that pathogen, sexual, and moral disgust sensitivity reflect systematic trait variation that is detectable by others and distinct from broader personality traits.
