Logarithmic Dependence of the Number of Possible Public Opinions in a Social Group and the Entropy of the Psychological State of the Social System

The paper substantiates the concept of “the number of accessible states of a social system”, which is the possible number of public opinions in a social group, functionally related to the numerical composition of the social group and the number of group members included in closed communication flows. The work describes logarithmic relationship between the number of possible public opinions (microcharacteristics of a social system) and the entropy of the psychological state of a social system (macrocharacteristics of a social system).
