Is cleanliness next to abstinence? The effect of cleanliness priming on attitudes towards harm reduction strategies for people with substance use disorders

Can exposure to a cleanliness prime affect moral judgements towards harm reduction strategies (HRS) for individuals with substance use disorders? Our research examined (a) the effect of a cleanliness prime on attitudes towards HRS and (b) whether this effect would be attenuated by a brief educational presentation. Participants were randomly assigned to a priming condition and an educational presentation condition. Results demonstrated that (a) the cleanliness prime did not shift attitudes towards HRS, however, (b) the educational presentations significantly shifted attitudes to be more positive after the Harm Reduction presentation and more negative after the Healthy Living presentation. The literature on priming is mixed and our results support a growing body of research challenging the robustness of cleanliness priming and also demonstrates that brief presentations can change attitudes. Our research has implications for education on the benefits of HRS in reducing disease transmission, refuse in the community, and overdose deaths.     

Basic value orientations and moral foundations: Convergent or discriminant constructs?

This study examined the structural and genetic links between value orientations, based on the theory of basic values, and moral concerns, based on moral foundations theory. We hypothesized both structural and genetic convergence of Conservation (versus openness to change) with Binding foundations and of Self-transcendence (versus self-enhancement) with Individualizing foundations. We analyzed self- and informant ratings from 924 participants with extended multitrait-multirater modeling and ran twin model analyses on self-ratings from 555 twin pairs. For Conservation and Binding foundations, we found partial convergence across different rater perspectives and a substantial genetic overlap, but also distinct genetic factors. Self-transcendence and Individualizing foundations were found to be structurally divergent, but genetically linked. We discuss the conceptual and measurement-related implications of the findings.     

“Internally Wicked”: Investigating How and Why Essentialism Influences Punitiveness and Moral Condemnation

Kant argued that individuals should be punished “proportional to their internal wickedness,” and recent work has demonstrated that essentialism—the notion that observable characteristics reflect internal, biological, unchanging “essences”—influences moral judgment. However, these efforts have yielded conflicting results: essentialism sometimes increases and sometimes decreases moral condemnation. To resolve these discrepancies, we investigated the mechanisms by which essentialism influences moral judgment, focusing on perceptions of actors’ control over their behavior, the target of essentialism (particular behaviors vs. actors’ character), and the component of essentialism (biology vs. immutability). Participants punished people described as having a criminal essence more than those with a non-criminal essence or no essence. Probing potential mechanisms underlying this effect, we found a mediating role for perceptions of control and weak influences of essentialism focus (behavior vs. character) and component of essentialism (biology vs. immutability). These results extend prior work on essentialism and moral cognition, demonstrating a causal link between perceptions of “internal wickedness” and moral judgment. Our findings also resolve discrepancies in past work on the influence of essentialism on moral judgment, highlighting the role that perceptions of actors’ control over their behavior play in moral condemnation.
