Causal explanation in history based on the Hempel's probabilistic model (rather than on the deductive-nomological one) together with some of its important weaknesses is presented and discussed. The article focuses on the possibilities and limitations of the utilization of psychological laws in the causal explanation as well as on the biases occurring in this explanation's acts and results. The historical examples of causal explanation of mass beliefs' changes and mass behavior employing the contemporary psychological theories are described. The idea that the scientific tradition in historiography ought to develop close to, rather than in the opposition to the narrativist position is presented.
