More education, less prejudice against sexual minorities? Evidence from compulsory schooling reforms

Utilizing exogenous variation in educational attainment induced by compulsory schooling reforms in 15 European countries, this study estimates the causal effect of education on individuals' attitudes towards sexual minorities with a regression discontinuity design. Using data from the World Values Survey and the European Values Study, this study finds more education reduces individuals' prejudice against sexual minorities. The findings imply minimum schooling policies can help to build a culture that is more tolerant of sexual minorities, which is beneficial to the minorities' wellbeing and social cohesion.
