Why do we misperceive air pollution? A scoping review of key judgmental biases

Air pollution stands as a primary environmental factor influencing mortality globally. Despite its significance, individuals frequently struggle to assess the risks associated with polluted environments. This paper delves into the psychological mechanisms that contribute to the discrepancy between public perception of air quality and objective measurements. Through an extensive literature review spanning several decades, six fundamental heuristics that underpin misperceptions of air quality are identified and examined. The article further explores the theoretical and practical implications of acknowledging these biases in the development of urban environmental policies. By addressing judgmental biases, urban planners can improve the communication of risk information among lay people and ensure that environmental improvements are acknowledged and valued by all members of the community.
