Psychological Correlates of Belief in Conspiracy Theories during the COVID-19 Pandemic: A Study of Robustness and Replicability of the Interaction Effect Between Dark Triad Personality Traits and Social Status

The prevalence and potential harmful effects of conspiracy theories have garnered increasing attention from psychologists. Understanding the psychological and social factors that contribute to belief in conspiracy theories is crucial for managing the preventative measures and promoting evidence-based decision-making. However, the field of psychology has recently faced challenges regarding the replicability and robustness of research findings. This bachelor thesis aims to investigate the robustness and replicability of interaction effects in a study on beliefs in conspiracy theories and attitudes towards anti-coronavirus measures during the COVID-19 pandemic. The thesis extracts data from a study by Hudecek et al. (2022) on the psychological correlates of beliefs in conspiracy theories in Germany. Specifically, it examines the interaction effect between dark triad personality traits and social status in predicting belief in conspiracy theories.

This bachelor thesis aims to investigate the robustness and replicability of interaction effects in a study on beliefs in conspiracy theories and attitudes towards anti-coronavirus measures during the COVID-19 pandemic. The thesis extracts data from a study by Hudecek et al. (2022) on the psychological correlates of beliefs in conspiracy theories in Germany. Specifically, it examines the interaction effect between dark triad personality traits and social status in predicting belief in conspiracy theories. The thesis utilizes resampling to test the robustness of the interaction effects. The analysis includes three subsamples (random, central, extreme) with three dropout conditions (10%, 20%, 30%). F tests are conducted to assess the variance between two given methods. The results revealed that the distribution of the interaction coefficients remain fairly stable in the central resampling approach pointing to robustness, however, significant inconsistencies were observed in the random and extreme resampling approach. Future research calls for replicating the study in diverse populations, investigating additional predictors of belief in conspiracy theories and testing the robustness and replicability of previous findings to address the replication crisis in the social sciences.Show less
