This is an interesting concept that I haven't seen developed in the literature. However, there is a lot that I haven't read so I may have missed it.

The idea that the coherence (or lack thereof) of one's cognitions is what's important sounds like the sort of concept that the constructivists would like a lot. More traditional CT authors (among whom I must count myself) would argue that the point to collaborative empiricism is to test cognitions against external reality so that the client ends up with cognitions that are more realistic and incidentally are more coherent.

My bet is that some of the constructivists would argue that external reality is unknowable, that all meaning is constructed by the individual, and that coherence is what's important.

If you're looking for a dissertation topic, this may have potential.
