Effects of Self-Legitimation and Delegitimation on Public Attitudes toward International Organizations: A Worldwide Survey Experiment

Abstract Public views on international organizations (IOs) have become a matter of central concern. While actors in world politics increasingly try to legitimize or delegitimize IOs, scholars have begun investigating such phenomena systematically. This paper provides the most comprehensive IO (de)legitimation study to date. Building on cueing theory, and considering input as well as output legitimacy, I examine the isolated and combined effects of delegitimation and self-legitimation on public perceptions of IOs. I concentrate on government criticism and citizen protests as two salient practices of delegitimation. In investigating self-legitimation, I focus on IOs’ public statements and institutional reforms. I study public opinion on the UN, World Bank, and WHO, as IOs of different functional scopes and levels of salience. In 2021, I conducted survey experiments on more than 32,000 citizens in ten countries worldwide (Australia, Canada, Colombia, Egypt, France, Hungary, Indonesia, Kenya, South Korea, and Turkey) – weighted by age, gender, region, and education. My main findings are: Delegitimation by governments and citizen protests has some limited effectiveness, depending on the IO in question. While IO self-legitimization statements and reforms in themselves do not boost public support for IOs, they are generally effective at neutralizing delegitimation attempts by governments and citizen protests.
