But the question is How are they controlled?  I think the answer is with
multiple models, by parallax.  A single model is never valid (sound), as
Miles points out.  Multiple models are required for validity and, hence,
control and prediction.  I'd go even further to claim that the more
complex the system, the more models required to effectively model it.

I would heartily agree -- and as the name of this group is "Applied Complexity" -- that that is sound practical advice. Curious if you are also arguing that *in general*, say

validity(M1) > validity(M2)

where M1 and M2 are sets of models and M1@ > M2@, or M1 ⊃ M2?

I think but am not sure that I am interpreting your parallax argument correctly. Do you mean that literally, or as a kind of heuristic? Does it assume a known or knowable state-space?
