I wonder whether part of the problem may be the abstract technical nature of the names “Perceptual Control Theory” and “Method of Levels”. “Cognitive-behavioural therapy” tells you it’s a therapeutic procedure, and that it involves both cognition and behaviour. MoL might in a parallel form be called “internal conflict resolution therapy” or something like that (I grant that a four-word label is hardly catchy, but it means something to an outsider, where as “Method of Levels” only suggests (to me) questions: Levels of what? Method to achieve what? Why should this be of any interest to me? What is it supposed to be a method to do?
“Perceptual Control Theory” does suggest something, but what it suggests may not be what we would like it to suggest. In my direct personal experience, it can turn off even Ph.D. psychological researchers, who image controlling other people by controlling what they can and cannot perceive (in the manner of Nazi control of the public media and the present-day concept of “Fake News” and “Alternative Facts”).
Granted, my direct experience of this was with a lunch-table of four female researchers, who I tried to get interested in PCT. They immediately rejected my attempts with a reaction along the lines of “Why would you want to promote something like that?”. [Aside: Does gender affect the likelihood of this kind of first impression? Why are there so few female contributors to CSGnet or this ne forum?]
The name “PCT” describes to us, the in-group, How Living Things Function, but it does not, unless you are part of our in-group, describe What Living Things Do. Nor does it suggest that PCT is a research domain with any relation to Psychology. The word “Control” sounds like domination, domination not of one’s own properties, but of others. One has to learn a bit about the Theory to realize that domiation is not what it is about at all.
Since control is central to the theory, I suppose it should be in the name somewhere. But where? On the other hand, perhaps it could be replaced by “Stabilization” such as in "Personal Environmental Stabilization Theory, which would unfortunately omit “perception”. But Personal Environmental Stabilization is the reason our ancestors survived for us to be alive now. Perceptual Control was the means, not the objective.
First impressions are important, and names provide a good part of a first impression. I don’t have solutions, but maybe these notions could jog loose some creativity, and produce attractive names for PCT, MoL, and other aspects and implementations of PCT, including my own “Layered Protocol Theory”.
