Abstract

Overview

The study addresses the influence of description formats on public risk perceptions, particularly concerning electromagnetic fields (EMF). A meticulously designed online experiment involving 629 participants evaluated the impact of various information formats.

Findings

• Participants were divided into three groups receiving different levels of information about EMF and cancer risks associated with mobile phones.
• Despite varying information, all groups showed increased risk perceptions for EMF sources after the intervention.
• Notably, participants with a strong belief in risk generalization exhibited markedly higher risk perceptions for EMF sources other than mobile phones.

Conclusion

The research supports Reyna's fuzzy trace theory, emphasizing the critical role of how information is presented in shaping risk perceptions. The study highlights the importance of addressing risk generalization beliefs in risk communication strategies.
