A new, international analysis links belief in Covid conspiracy theories to a lower tendency to support and participate in public health efforts to mitigate the spread; but people’s sense of morality appears to weaken this link. Theofilos Gkinopoulos of the University of Crete, Greece, and colleagues present these findings in the journal PLOS ONE.
People who believe in Covid conspiracy theories – for instance, the idea that the ongoing pandemic is fake and was designed to control people – may avoid using masks or getting vaccinated, posing a significant threat to public health. In addition, recent research suggests that people’s sense of morality plays a significant role in conspiracy theory beliefs.
To help clarify the role of morality in Covid conspiracy theories and prevention, Gkinopoulos and colleagues conducted a study of 49,965 adults across 67 countries. The data were collected as part of the International Collaboration on the Social & Moral Psychology (ICSMP) of Covid. Participants completed questionnaires evaluating several measures, including belief in Covid conspiracy theories, support for public health policies, adherence to public health behaviours, individual sense of morality, and morality in the context of cooperation within groups.
Statistical analysis of the results suggests that belief in Covid conspiracy theories is associated with reduced support of public health policies and less adherence to public health behaviours. But both individual and cooperative morality appear to weaken the impact of belief in conspiracy theories on support for and participation in public health measures.
These findings highlight the role of morality in conspiracy theory beliefs, which could help inform efforts to reduce such beliefs and encourage behaviours to prevent the spread of Covid. The authors suggest that such efforts could involve appeals to people’s moral foundations.
The researchers also outline several possible directions for future research, including experimental investigation of links between moral traits, belief in different forms of conspiracy theories, and support for public health policies.
The authors added: ‘Believing in conspiracy theories reduces adoption of public health behaviours, but moral identity and morality-as-cooperation significantly mediate this relationship. Beliefs in conspiracy theories do not simply constitute antecedents of cognitive biases or personality-based maladaptive behaviours, but are morally infused and should be dealt as such.’
