Constraining Free-riding In Public Goods Games: Designated Solitary Punishers Can Sustain Human Cooperation

We take it for granted in modern society that having leaders is a necessity. Yet hunter-gatherers, those probably living most like how humans did as we evolved, do not have leaders and dislike anyone trying to do so.


People assume that leaders are a natural outcome of a dominance hierarchy, but we show that possibly it's because one person in charge of 'policing' others is as effective as allowing everyone to do it, like hunter-gatherers, but has the advantage that one person is clearly responsible.


Policing of each other is necessary to prevent a 'tragedy of the commons'.
