Trust Is Key: Determinants of False Beliefs about Climate Change in Eight Countries

Abstract

Science has established the human-caused nature of climate change, yet the prevalence of climate-related misinformation persists, undermining public understanding and impeding collective action. Strikingly, existing research on belief in misinformation about climate change has disproportionately focused on WEIRD (Western, Educated, Industrialized, Rich, and Democratic) countries. To move beyond this, our online survey (N=8541) includes high-income countries in North America (US), Western Europe (France, Germany, UK) and East Asia (Japan), as well as an upper-middle income country in South America (Brazil) and lower-middle income countries in South Asia (India and Pakistan). By examining the interplay of news media usage, information sources, and trust in these sources, we advance our understanding of how these factors influence belief in climate change-related misinformation in diverse socio-cultural contexts. Across countries, we found that the strongest determinants of belief in misinformation about climate change were identifying as right-wing (compared with left-wing), consuming less offline news, having less trust in scientists, environmental activists, as well as international organizations, and having more trust in politicians, celebrities, and energy companies. Overall, trust in sources of information about climate change and demographic variables were much stronger predictors of belief in misinformation about climate change than reported news consumption (online, offline or on social media). These findings suggest that trust is key to understanding belief in false information about climate change.
