What constitutes cooperation? (previously)
Because much in the complex system of human interaction and coordination is about negotiating norms, customs, institutions, constitutions to guide and constrain future interaction in mutually-preferable ways, I think:
1. 'institution and constitution design'
deserves special attention.
This is despite it perhaps (for a given 'coordination moment') being in theory reducible to preference elicitation or aggregation, searching outcome space, negotiation, enforcement, ...
There are failure modes (unintended consequences, concentration of power, lost purposes, corruptability, poor adaptability, plain old inefficacy) and patterns for success (stabilising win-win equilibria, reducing inefficiencies, improving collective intelligence and adaptability) which are specific to this process of negotiating and developing institutions (there are patterns, because the complex system has emergent structure like trust, corruption, coalitions, information propagation, ...).
Said briefly: much (most?) coordination is about coordination because a) humans are that type of creature and b) we live in a highly iterated world.
