Personality shapes how people evaluate and share information through stable dispositions that influence cognition, emotion, and social behavior. Research grounded in the Big Five framework links traits like openness, conscientiousness, and agreeableness to different patterns of responsiveness to persuasive misinformation. Underlying cognitive styles are also critical: analytic thinking versus intuitive, quick judgments determine whether someone scrutinizes a claim or accepts it. Daniel Kahneman at Princeton University articulated this dual-process model, which helps explain why some individuals are more resistant to misleading persuasive appeals while others rely on intuition and social cues.
Cognitive and dispositional causes
Personality affects the mental processes that create susceptibility. Individuals high in openness tend to seek novel information and may therefore encounter and sometimes adopt fringe claims, while those high in conscientiousness are more likely to verify sources and exhibit skepticism. Research by David G. Rand at MIT and collaborators has found that greater reflective cognitive style and engagement with analytic processes correlate with reduced belief in false headlines, illustrating how disposition and cognitive strategy interact. Nuance matters: openness can foster critical curiosity in some cultural contexts while promoting credulity where fact-checking norms are weak.
Social dynamics and consequences
Traits that shape social behavior influence propagation of persuasive misinformation. High agreeableness and collectivist cultural norms can increase willingness to share information that maintains social bonds, even if inaccurate; this amplifies misinformation in tight-knit communities and contested territories. Sander van der Linden at University of Cambridge demonstrates how social influence and identity signaling alter receptivity, and how targeted interventions can inoculate audiences against manipulation. The consequences extend beyond individual belief: persuasive misinformation can erode public trust, distort democratic debate, and undermine responses to public-health and environmental crises, including climate policy debates that depend on accurate shared facts.
Understanding personality’s role suggests tailored strategies: strengthening analytic skills and media literacy among groups low in reflective thinking, and designing respectful, identity-aware corrections for communities where social cohesion drives sharing. These approaches recognize that susceptibility is not mere gullibility but a product of cognitive style, dispositional priorities, and cultural context that together shape how persuasive misinformation takes hold.
