 Collective acceptance is not simply a matter of psychological attitudes standing in some straightforward causal relation to the external world as is the case, for instance, with common or garden-variety intentions, including the joint intentions definitive of basic joint actions. The idea is not that a group forms a joint intention to (say) push a boulder up a hill and, thereby, jointly cause the boulder to be relocated to the top of the hill. Rather the notion of a performative is typically invoked (Austin 1962; Searle 2010: 11).
