Clarifying the Relations between Intellectual Humility and Misinformation Susceptibility
Misinformation is widespread and consequential. Thus, identifying psychological characteristics that might mitigate misinformation susceptibility represents a timely and pragmatically important issue. One construct that may be particularly relevant to misinformation susceptibility is intellectual humility (IH). As such, we examined whether IH is related to less misinformation susceptibility, what aspects of IH best predict misinformation susceptibility, and whether these relations are unique to IH. Across three samples, IH tended to manifest small-to-medium negative relations with misinformation susceptibility (pseudoscience, conspiracy theories, and fake news). IH measures assessing both intrapersonal and interpersonal features tended to be stronger correlates of misinformation susceptibility than measures assessing either intrapersonal or interpersonal features in isolation. These relations tended to remain robust after controlling for covariates (honesty-humility, cognitive reflection, political ideology). Future research should leverage our results to examine whether IH interventions not only reduce misinformation susceptibility but also lessen its appeal for those already committed to misinformation.
