Social movements' impact on inequality beliefs, preferences for redistribution, and political participation

We study whether exposure to social movements campaigning against income and gender income inequality shifts individual beliefs about inequality, reshapes preferences for redistribution, and translates into political participation in the UK. Since the Great Recession of the 2010s, the UK has seen significant growth in social movements, particularly those mobilizing against inequality. We focus on income and gender income inequality, two persistent and politically contested forms of inequality in advanced democracies like the UK. Responses to social movements can diverge sharply between them. Using observational data, we show that exposure to protests against inequality is strongly correlated with increased support for redistribution. To identify causal effects, we complement this evidence with an online experiment in which we randomly assign 1,436 UK citizens to follow real social movement content focused on either income or gender income inequality over a two-week period on Facebook. Participants exposed to information about income inequality increase support for reducing income disparities, while those exposed to gender income inequality support targeted measures to address gender gaps. Both groups favor higher taxes on the wealthy and are more likely to take political action, including signing a petition, contacting a politician, or meeting a public official.
