The behavior of a group consisting of big number of identical participants in the case of a personal binary choice is considered. The information received from other members of a group at pair meetings and a general information on number of the participants who have chosen each alternatives before define the choice of each partner. The dynamic model of collective behavior based on Markov chain is constructed. Investigated the variants of behavior of a group at various level of susceptibility of the particular participant to the common information received through mass media. It is proved, that at a considerable susceptibility through certain time herd behavior arises. It is shown that in case of distortion of the common information the behavior of the group is changing in the direction of distortion of the general information.
