Essay by Julien Lie-Panis: “Every human society, from the smallest village to the largest nation, faces the same fundamental challenge: how to get people to act in the interests of the collective rather than their own. Fishermen must limit their catch so fish stocks don’t collapse. People must respect others’ property and safety. Citizens must pay taxes to fund roads, schools and hospitals. Left to pure self-interest, no community could endure; the bonds of collective life would quickly unravel.
The solutions we’ve devised are remarkably similar across cultures and centuries. We create rules. Then we appoint guardians to enforce them. Those who break the rules are punished. But there’s a problem with this approach, one that the Roman poet Juvenal identified nearly 2,000 years ago: Quis custodiet ipsos custodes? Who will guard the guards themselves?
Fisheries appoint monitors to prevent overfishing – but what if the monitors accept bribes to look the other way? Police officers exist to protect everyone’s property and safety – but who ensures that they don’t abuse their power? Governments collect taxes for public services – but how do we stop officials from diverting the funds to their own accounts?
Every institution faces the same fundamental paradox. Institutions foster cooperation by rewarding good behaviour and punishing rule-breakers. Yet they themselves depend on cooperative members to function. We haven’t solved the cooperation problem – we’ve simply moved it back one step. So why do institutions work at all? To understand this puzzle, we need to first ask what makes human cooperation so extraordinary in the natural world.
Cooperation is everywhere in nature. Walk through any forest, peer into any tide pool, observe any meadow, and you’ll witness countless partnerships that seem to defy the brutal logic of natural selection. Far from being mysterious, these alliances follow predictable patterns that evolutionary biologists have come to understand well. A handful of basic mechanisms explain cooperation from ant colonies to coral reefs: kinship, reciprocity and reputation…(More)”.
