Abstract

Average monthly fluctuations of three indicators of public opinion were analyzed. Expected seasonality was not found. Hypothesis of redemption of seasonal fluctuations as a result of systematic error (an artifact of data collection) was tested and rejected. It is shown with a high probability that the local stability of the public opinion indicators is objectively existing effect. With this in mind, one can say, that the lack of seasonality in regular social and political surveys can be considered as evidence in favor of the quality of data.
