Abstract: In this paper Nowak–Szamrej–Latané model is reconsidered. This computerised model of opinion formation bases on Latané theory of social impact. We modify this model to allow for multi (more than two) opinions. With computer simulations we show that in the modified model the signatures of order/disorder phase transition are still observed. The transition may be observed in the average fraction of actors sharing theith opinion, its variation and also average number of clusters of actors with the same opinion and the average size of the largest cluster of actors sharing the same opinion. Also an influence of model control parameters on simulation results is shortly reviewed. For a homogeneous society with identical actors’ supportiveness and persuasiveness the critical social temperatureTCdecreases with an increase of the number of available opinionsKfromTC= 6.1 (K= 2) via 4.7, 4.1 toTC= 3.6 forK= 3, 4, 5, respectively. The social temperature plays a role of a standard Boltzmann distribution parameter containing social impact as the equivalent of energy or one may think about it just as on a noise parameter.
