High economic inequality is linked to moralistic thinking

High economic inequality has been identified as a key factor in fuelling political polarization, but the underlying psychological mechanisms behind this phenomenon are not well understood. We propose that economic inequality threatens people's experience of social order and control, leading them to adopt moralistic mindsets – yet this mindset may sow divisions in society. Using data from social media, a multinational survey across 41 regions around the world, and an experimental approach, our work shows that economic inequality is associated with the use of moral language online, harsher moral judgments, and a desire for clearer social and moral rules in society. Together these findings demonstrate that economic inequality is linked to the tendency to see the world through a moral lens. Understanding how societal structures impact our moral perspectives may help us bridge the growing divisions between people and foster a more united society.
