Abstract: The resurgence of nationalism and anti-globalization is a world-wide phenomenon in current times. Concentrating on nationalism as a personal political attitude, this paper tries to examine the impact of social capital on people’s inclination to nationalism. Based on fixed effects model and data from World Value Survey, we find a negative impact of social capital on the inclination to nationalism, which shows that people with less social capital have more possibility to support nationalism. Sensitivity analyses shows the robustness of the conclusion.
