<p>Prior research has demonstrated that inequality is associated with economic, psychological, social, political, and public health issues. Social trust, as one of the vital components of social capital, also has long-term social and economic outcomes. However, little research has been performed to explore the link between inequality and social trust. This paper fills this gap by investigating the effects of subjective inequality on social trust, using data from the International Social Survey Program's 2019 Social Inequality V survey in the United States. Employing generalized logistic regression models, this study indicates that people’s perceptions and assessments of economic inequality and income inequality have substantial effects on social trust formation. However, the possibilities of increasing or decreasing social trust remain the same if market inequality changes. The study also predicts that higher age, being male, being employed, and living with a partner are significant predictors of social trust formation. While there is a favorable link between education and social trust, having more education does not equate to having a higher social trust score. The study recognizes the empowering role of equality and fairness at micro-level factors in the formation of social trust and concludes that addressing inequality and trust erosion requires a sound neighborhood environment and equitable or justifiable earnings.</p>
