Does institutional trust influence citizens’ support for democracy? This paper uses data from the second wave of the Asian Barometer Survey for 13 counties. This study has utilized the perspectives of institutionalism, culturalism, and critical citizens, respectively, to review the relationship between institutional trust and democratic support, which were then further tested by adding traditional social values according to the country’s status among East Asian countries. The empirical results of this study prove that institutional trust influences democratic support. Our research supports culturalism, but disagrees with the position of institutional theorists that there is no relationship between institutional trust and democratic support. Furthermore, contra previous research, this study finds that critical citizens support democracy less than non-critical citizens.
