This study applies machine learning to rank 115 individual- and country-level variables using data from 56,072 respondents across 28 countries during the early COVID-19 period. Results highlight key individual predictors and identify differences across country-level relationships.","University of Groningen  \nIdentifying important individual-and country-level predictors of conspiracy theorizing  \nPsyCorona Collaboration  \nPublished in:  \nEuropean Journal of Social Psychology  \nDOI:  \n10.1002/ejsp.2968  \nIMPORTANT NOTE: You are advised to consult the publisher's version (publisher's PDF) if you wish to cite from it.
