Feelings of disgust, a disease avoidance emotion, vary among individuals. The present study investigated if individual differences in pathogen disgust sensitivity predict the level of disgust evoked by crowded places. Interested in the universality of this relationship, we studied it across countries (Study 1), and examined temporal differences in pathogen disgust sensitivity (Studies 2 and 3). Participants completed a pathogen disgust scale and rated the level of disgust evoked by two crowded situations. Data were collected in 2018 (before the COVID-19 pandemic), in 2020 (at the height of the pandemic) and in 2022 (later in the pandemic). Across studies and countries, individuals' pathogen disgust sensitivity predicted the disgust evoked by the situations. Moreover, the data revealed a significant increase in pathogen disgust from 2018 to 2020, most likely because of higher pathogen presence during the pandemic, before significantly decreasing in 2022 after the pandemic had progressed. This study captures a rare opportunity, investigating how these crises relate to pathogen disgust sensitivity and the perception of crowded spaces. Further, our longitudinal study is among the first showing changes in pathogen disgust sensitivity over time and monitoring the effect of the pandemic.
