Moral Intuitions About Stigmatizing Practices and Feeding Stigmatizing Practices: How Haidt's Moral Foundations Theory Relates to Infectious Disease Stigma.

Despite extensive stigma mitigation efforts, infectious disease stigma remains common. So far, little attention has been paid to the moral psychology of stigmatizing practices (i.e. beliefs, attitudes, actions) rather than the experience of being stigmatized. Addressing the moral psychology behind stigmatizing practices seems necessary to explain the persistence of infectious disease stigma and to develop effective mitigation strategies. Our article proposes building on Jonathan Haidt's moral foundations theory, which states that moral judgements follow from intuitions rather than conscious reasoning. Conceptual analysis was conducted to show how Haidt's five moral foundations can be connected to (i) moral judgements about stigmatizing practices and (ii) stigmatizing practices themselves. We found that care/harm, fairness/cheating, loyalty/betrayal and sanctity/degradation intuitions can inform moral judgements about stigmatizing practices. Loyalty/betrayal and sanctity/degradation intuitions can sometimes also feed stigmatizing practices. Authority/subversion intuitions can inform moral judgements and stigmatizing practices towards people who disrespect authoritative rules meant to protect public health. Moral dumbfounding and posthoc reasoning might explain the persistence of stigmatizing practices. In conclusion, this study demonstrates the relevance of Haidt's approach to infectious disease stigma research and mitigation strategies. We hope that this study motivates researchers to further test and assess this approach.
