Communicative convergence

How much convergence is achieved in the communication will naturally depend on there being a measure of correspondence between P1 and P2 knowledge. 

The closer the correspondence, clearly, the easier it is, potentially, to converge, and the less close the greater the need to negotiate a convergence.

Convergence is always only partial.

Negotiating convergence

Bringing our knowledge (both systemic and schematic) to bear in an appropriate way so as to converge on agreed meaning is, then, a complex process, and it is a process that we only embark upon in the first place if we are prepared to co-operate. But then we also need to know what the accepted procedures or ground rules are for the co-operative negotiation of meaning.
