The subject of this paper is the comparison of the results of the survey of public opinion before and after the change of the regime in Serbia as of 5th October 2000. Both researches (May 2000 and June 2001) were field researches, reaching for households, using random sample of the citizens of Serbia, without Kosovo. The obtained results show that the change of regime in Serbia was followed with the change in the sense of decreased expression of authoritarianism and ethnocentrism after one year of democratic rule. However, the question which still remains is - whether the registered change is the result of social-political circumstances, and whether it is the reflection of essential changes of value systems, or just different experience of social desirability of particular attitudes.
