Social Misperceptions of Climate Change Effects: A Review of Pluralistic Ignorance

Climate change represents a critical threat to human survival, yet significant misperceptions persist regarding its anthropogenic origins and societal consequences. One important psychological mechanism contributing to this gap is pluralistic ignorance, wherein individuals mistakenly believe that their concerns about climate change are not shared by others. This misperception fosters collective inaction, as people suppress their own environmental concerns to align with perceived social norms. Additionally, to avoid feelings of guilt, anxiety, or helplessness, individuals may disengage from climaterelated information, further reinforcing apathy and denial. This review paper examines the role of social misperceptions in shaping public attitudes toward climate change, particularly among adult populations. It synthesizes existing literature on pluralistic ignorance and its influence on environmental behavior, highlighting how social norms and cognitive biases impede collective climate action. Furthermore, the paper explores evidence-based strategies grounded in social cognition, such as norm-based interventions, climate communication, and community engagement, that can enhance climate efficacy and foster a sense of climate hope. By addressing these social and psychological barriers, the study aims to provide insights into promoting more informed, proactive, and collective responses to climate change
