Every interaction in the MAP — services, data access, participation, relationships — is governed by consent. Promises, Offers, and Agreements are the formal structures that embody and enforce this principle.
Consent is not formally defined in the MAP, but it is often taken to acquire its meaning from Sociocracy, where it is (mistakenly) contrasted with “consensus”.1)
There is a long history of misunderstanding here. An ISO definition of consensus is “no sustained opposition to substantial issues”, which seems hard to distinguish from the Sociocratic principle of consent. People who suggest there is a distinction often seem to take “consensus” to mean “unanimity”, which is rarely if ever intended.
