Public confidence is a phenomenon of social change, being characterised for the periods of political and cultural revolutions. Twenty years of democratic transformations in the post-communist countries and multiple changes in the ruling elite have given responders a basis to negative assessment of the quality of establishment. A characteristic feature of this assessment is a low level of confidence in the institutions of political life. An increase in confidence in these institutions may be connected with their longer functioning in social consciousness and feeling its positive effects by citizens.
