Cooperation has no general solution, only historically specific ones

Evidence

But all that means is that there is no solution at this level of generality. The problem of cooperation cannot be solved merely at the level of decision theory, social psychology, or the general theory of social institutions. In fact, that there is no one problem of cooperation: the problem is always how a given set of people are to cooperate. — Diego Gambetta, Trust - Making and Breaking Cooperative…, 228

Categorization

• XREF: Resonates with the reader’s project — Saramago’s blindness epidemic shows cooperation dissolving because the specific observable constraints of a given group vanish; no general theory rescues it.
• DEEPTHINKING: A paradigm-shifting reframing: cooperation is not one problem awaiting a universal answer but an endlessly particular one — this resists one-sentence summary.
