Public perceptions of scientific facts are often polarized and frequently diverge from scientific consensus. This talk examines why some risks trigger strong public concern while more serious dangers are underestimated, focusing on the role of emotions, statistical misunderstandings, and cognitive biases in shaping beliefs and behavior. It will show how even well-educated individuals may reject scientific evidence when it conflicts with prior convictions, political identities, or worldviews, and how misconceptions about randomness and causality can foster superstition and misinformation. The talk also explores the social dynamics that amplify these processes and contribute to polarization on issues such as climate change and public health. Finally, it discusses possible solutions, including improved statistical literacy, transparent communication of evidence, and emerging AI-based interventions that have shown promise in increasing acceptance of scientifically supported beliefs and policies. Ultimately, the talk argues for a stronger culture of evidence in both society and decision-making.
