Democracy as the Rule of a Small Many

What is the optimal size of a democratic society? While not taking an explicit stand on this issue, Hélène Landemore's model of democracy in Democratic Reason suggests that democracies ought to be small, certainly smaller than many existing states. If, as Landemore argues, we must rely on the random selection of representatives, then we should be concerned about both the size of the population and the way cognitive diversity is distributed within it. Given the realities of party politics and media framing, this means that smaller political societies will yield wiser decisions than very large ones.
