Why are some countries democratic and democratize continuously, while others stagnate? According to theories on political culture, citizens' attitudes are crucial elements. In this context the discussion on critical citizens is gaining prominence: Critical citizens are regarded as a threat to democratic stability or as promoter for democratic reforms. Based on the International Social Survey data (2004), I will contribute some empirical evidence to this controversy. In addition to the common equating of criticism with discontentment, I will also include the normative disposition of “critical” attentiveness. Bivariate and multivariate analyses show that contentment, praised in previous research, or discontentment, as suggested by recent studies, are not the decisive attitudes. It is the political attentiveness which promotes democracies.
