Here, you are mistaken, just as you are mistaken in your persistent belief that Kent’s 1993 demo of conflictive control is all there is to say about collective control and all that Kent has presented about collective control. A much larger proportion of collective control concerns conventionalized ways to avoid conflict so that the even larger proportion, more ad hoc forms of collective control, can proceed while minimizing or avoiding conflict.
You still haven’t indicated how you would model a handshake. Other than conflict, you have no models in which “other people are part of the environmental component of the feedback connection between your output and the variable(s) you are controlling”.
In LCS IV, the Handbook vol. 1, read Kent’s chapter and Martin’s chapter, and read Martin’s 4-volume book. Practically all of it is about the latter kind of collective control.
Even if it had been, it would not have been for me, because you are not the only reader.
Addendum, next day:
Bill’s 1995 conversation with Bruce Abbott about contrafactual beliefs is relevant. If factual data can’t be rationalized to fit then either denial or reorganization follows. I suppose denial is an extreme form of rationalization.
