Building on the Moral Foundations Theory and findings regarding the linkage of values, convictions and beliefs, the aim of the study was to compare people displaying various constellations of moral foundations regarding their tolerance of ambiguity, fear of COVID-19 (FCV), endorsement of COVID-19 conspiracy theories and the extent to which they believed in the effectiveness of five COVID-19 preventive measures. This study was self-report-and questionnairebased (N = 212), performed on the general public (aged from 18 to 65). Moral foundations clustered into four groups: Individualizing, Binding, Anti-Individualizing and Generally Moral. The endorsement of Individualizing values (Harm/Care, Fairness/Reciprocity) was linked to higher FCV and higher rating of the effectiveness of COVID-19 preventive measures. Endorsing Binding values (Ingroup/Loyalty, Authority/Respect and Purity/Sanctity) was related to lower tolerance of ambiguity and displaying higher conspiracy beliefs. Findings are discussed in the light of their meaning of values for socially responsible behaviour during a pandemic.
