Abstract:
Recent research has shown that sleep is associated with moral judgment. The present research reports a set of six preregistered cross-sectional studies which explore the association between moral utilitarianism and sleep quantity and quality at both the acute and chronic levels. A total of 582 participants drawn from diverse populations addressed various measures of sleep quantity, sleep quality, and moral utilitarianism. We report a meta-analysis which showed only a weak association between sleep and moral utilitarianism. Despite the heterogeneity in the samples and methods employed, equivalence tests ruled out the possibility that we missed medium to strong effect sizes. The scholars discuss the implication of these findings in the light of the moral judgment literature.
