The solution to the tragedy of the commons

Article by evolutionary biologist David Sloan Wilson. Some excerpts:

"Evolutionary theory’s individualistic turn coincided with individualistic turns in other areas of thought. Economics in the postwar decades was dominated by rational choice theory, which used individual self-interest as a grand explanatory principle. The social sciences were dominated by a position known as methodological individualism, which treated all social phenomena as reducible to individual-level phenomena, as if groups were not legitimate units of analysis in their own right (Campbell 1990). And UK Prime Minister Margaret Thatcher became notorious for saying during a speech in 1987 that 'there is no such thing as society; only individuals and families.' It was as if the entire culture had become individualistic and the formal scientific theories were obediently following suit."

'Unbeknownst to me, another heretic named Elinor Ostrom was also challenging the received wisdom in her field of political science. Starting with her thesis research on how a group of stakeholders in southern California cobbled together a system for managing their water table, and culminating in her worldwide study of common-pool resource (CPR) groups, the message of her work was that groups are capable of avoiding the tragedy of the commons without requiring top-down regulation, at least if certain conditions are met (Ostrom 1990, 2010). She summarized the conditions in the form of eight core design principles: 1) Clearly defined boundaries; 2) Proportional equivalence between benefits and costs; 3) Collective choice arrangements; 4) Monitoring; 5) Graduated sanctions; 6) Fast and fair conflict resolution; 7) Local autonomy; 8) Appropriate relations with other tiers of rule-making authority (polycentric governance). This work was so groundbreaking that Ostrom was awarded the Nobel Prize in economics in 2009."


"Multilevel selection theory, which envisions natural selection operating on a multi-tier hierarchy of units, had become more widely accepted. [...] Lin’s [Ostrom's] core design principle approach dovetailed with multilevel selection theory, which my fellow-heretics and I had worked so hard to revive. Her approach is especially pertinent to the concept of major evolutionary transitions, whereby members of groups become so cooperative that the group becomes a higher-level organism in its own right. This idea was first proposed by cell biologist Lynn Margulis (1970) to explain how nucleated cells evolved from symbiotic associations of bacteria. It was then generalized during the 1990s to explain other major transitions, such as the rise of the first bacterial cells, multicellular organisms, eusocial insect colonies and human evolution (Maynard Smith and Szathmary 1995, 1999)."

"Lin’s design principles (DP) had 'major evolutionary transition' written all over them. Clearly defined boundaries (DP1) meant that members knew they were part of a group and what the group was about (e.g., fisherman with access to a bay or farmers managing an irrigation system). Proportional equivalence of costs and benefits (DP2) meant that members had to earn their benefits and couldn’t just appropriate them. Collective choice arrangements (DP3) meant that group members had to agree upon decisions so nobody could be bossed around. Monitoring (DP4) and graduated sanctions (DP5) meant that disruptive self-serving behaviors could be detected and punished. Fast and fair conflict resolution (DP6) meant that the group would not be torn apart by internal conflicts of interest. Local autonomy (DP7) meant that the group had the elbow room to manage its own affairs. Appropriate relations with other tiers of rule making authority (DP8) meant that everything regulating the conduct of individuals within a given group also was needed to regulate conduct among groups in a multi group population."
