ABSTRACT
Research reveals a bias for natural versus synthetic drugs. We sought to determine if this bias is associated with religiosity. Three cross-sectional studies (N = 1399 U.S. participants) were conducted to examine the impact of religiosity on the naturalness bias in the drug and vaccine domains. We assessed measures of religiosity, preferences for natural versus synthetic drugs and vaccines in hypothetical scenarios, and a health-related behavior (COVID-19 vaccination status). The results revealed that participants high versus low in religiosity had stronger preferences for natural versus synthetic drugs and vaccines. Furthermore, participants high versus low in religiosity were less likely to have taken the COVID-19 vaccine, and the natural drug bias was a mediator of this effect. Overall, participants higher in religiosity had a stronger preference for natural versus synthetic drugs and vaccines, and this preference had implications for health behavior.
ABSTRACT
BACKGROUND: It is imperative to understand the predictors of vaccine hesitancy for current and future pandemics. METHODS: A representative sample (age, race & gender) of 1054 US adults was collected in October 2020 to examine the predictors of vaccine hesitancy. Participants were asked several questions including their intention to receive a vaccine for the novel coronavirus. RESULTS: Predictors significantly associated with a greater intention to receive a COVID-19 vaccine included greater perceived feelings of vulnerability to COVID-19, having received a flu vaccination at the time the question was asked, more liberal political orientation, non-Black race, male gender, and a lower naturalness bias. CONCLUSIONS: Vaccines are essential for mitigating current and future pandemics. Multiple strategies are important in encouraging people to be vaccinated and the predictors highlighted here and elsewhere are likely to be useful targets.
