Cooperation is enforced through community expulsion of those who deviate

Evidence

Cooperation, as Genovesi conceived it, works through conscience and cultural - or in some cases divine - sanction. Deviation from what is regarded as an acceptable mode of conduct is met with expulsion from the community. A merchant whom no one trusts will not be able to remain in business for very long. — Diego Gambetta, Trust - Making and Breaking Cooperative…, 1743

Categorization

• XREF: Community expulsion as the sanction mechanism maps onto Milgrom’s reputation/boycott findings and onto what blindness destroys by removing the ability to identify deviators. — connects to: Expellee organizations enforced an orthodox policy line by punishing political deviation — Pertti Ahonen, Domestic Constraints on West German…, 105; State repression of dissent solidifies community solidarity and legitimates even lethal internal enforcement — Charles Tilly, Regimes and Repertoires, 539
• ADDENDUM: The merchant expelled because no one trusts him is the pre-modern version of the private-judge reputation systems in the reader’s law-merchant material.
• corroborated: 2 independent passages support this claim — Diego Gambetta, Trust - Making and Breaking Cooperative…, 1743
