Attitude strength as a novel predictor of willful ignorance

Willful ignorance is a pervasive phenomenon with significant consequences for decision-making, belief maintenance, and social polarization. While past research has identified various motivational and contextual factors underlying this behavior, less attention has been paid to attitude characteristics that shape the likelihood of engaging in willful ignorance. Addressing this gap, this paper introduces attitude strength as a critical and heretofore unexplored psychological factor that should affect when and why individuals engage in willful ignorance. We argue that strong attitudes, such as those held with certainty, are highly accessible, or are perceived as morally relevant, are particularly likely to elicit willful ignorance. Drawing on cognitive dissonance theory and motivated reasoning, we synthesize findings across domains, from political partisanship to responses to misinformation and AI-mediated communication.
