This book, prepared under the auspices of the ISA research committee on Comparative Sociology, focuses on a worldwide phenomenon: political mistrust, observable in almost all countries, in both established democracies and in authoritarian regimes.But ubiquity does not signify uniformity. The diversity of political regimes generates a multiplicity of forms and intensities of mistrust. Political mistrust seems inherent even in advanced democracies and in semi-democracies, where citizens are better prepared and more prone to criticize the dysfunctions of institutions and condemn the misconduct of politicians. Political mistrust is greatly nourished in many countries by a wide practice of public corruption. Of particular sociological interest is the vulnerability of political elites and of their frequent condemnation to “civil death”.
