Among many different subjects, opinion dynamics is one of the most studied in the field of sociophysics. Obviously, public opinion, which can be empirically measured for example as a result of political voting, consumer choices (e.g., Coca-Cola or Pepsi?), etc., is created from individual opinions. Therefore, to build the model, which describes the dynamics of the public opinion, one needs to model how individual opinions change, namely a suitable model of social response.

Models of social response concern the identification and delineation of possible responses to social pressure. Most of them are based on simple one-dimensional conceptualizations of conformity and its alternatives even though more sophisticated two- and three-dimensional models have been available for a number of years. The diamond model and the double diamond model are perhaps the most refined of the two- and three-dimensional formulations, respectively. The diamond model is also particularly useful in building agent-based models of opinion dynamics, because it gives unambiguous operational definitions of basic types of social response. In fact, the diamond model is actually a ready recipe for a microscopic model of opinion dynamics. In this work, we will present the idea of diamond and double diamond model as well as their implications for the agent-based modeling.
