This paper contributes to the Democracy versus Epistocracy debate (Brennan and Landemore 2022) by providing a theoretical framework and a criterion to choose between democratic, hybrid and epistocratic modes of political governance. From a normative perspective, we claim that the specificity of information should (at least partially) guide the choice between these modes of political governance because of its impact on costs of political governance. The main logic of the model is the following: an issue has a degree of information specificity that determines costs of political governance combined in a Social Costs Function. Therefore, the model helps to assess the relative efficiency between democratic, hybrid and epistocratic decision-making procedures to reach collective choices.
