 The theoretical problems involved in measuring overall freedom include that of how an agent’s available actions are to be individuated, counted and weighted, and that of comparing and weighting different types (but not necessarily different sources) of constraints on freedom (such as physical prevention, punishability, threats and manipulation). How are we to make sense of the claim that the number of options available to a person has increased? Should all options count for the same in terms of degrees of freedom, or should they be weighted according to their importance in terms of other values? If the latter, does the notion of overall freedom really add anything of substance to the idea that people should be granted those specific freedoms that are valuable? Should the degree of variety among options also count? And how are we to compare the unfreedom created by the physical impossibility of an action with, say, the unfreedom created by the difficulty or costliness or punishability of an action? It is only by comparing these different kinds of actions and constraints that we shall be in a position to compare individuals’ overall degrees of freedom. These problems have been addressed, with differing degrees of optimism, not only by political philosophers (Steiner 1983; Carter 1999; Kramer 2003; Garnett 2016; Côté 2020; Carter and Steiner 2021) but also by social choice theorists interested in finding a freedom-based alternative to the standard utilitarian or ‘welfarist’ framework that has tended to dominate their discipline (e.g. Pattanaik and Xu 1991, 1998; Hees 2000; Sen 2002; Sugden 1998, 2003, 2006; Bavetta 2004; Bavetta and Navarra 2012, 2014).
