Rick, Richard and I have noted about the problems (different ways to understand) of the concept of â€œbehaviorâ€?.
However, I think it is not the core point of â€œendless confusionâ€?, but rather the most central concept of â€œcontrolâ€?, which is used in a fuzzy every day meaning. In everyday speech (I
think as non-English speaker, but inferring from the use of the respective word â€œkontrolliâ€? in Finnish) control is a synonym to adjust, affect, alter, keep in place, restrict, surveillance etc. (And it is many of these meanings which have caused the repulsive
aura for the concept.)
In strict and technical use the definition of control – if I have understoood it right – is something like: â€œcausingg the value (measure) of some variable towards some reference value
and keeping it near itâ€?.
The problem with the many every day meanings of â€œcontrolâ€? is that there is no reference value. Any variable has always some value but that does not mean that it is controlled. Similarly
adjusting or changing the value to some other value is not controlling, it is affecting. Neither the keeping of the value to some level is not controlling but stabilizing. Only if there were a the (prior, a priori) reference value towards what the affected
value is changed or near what it is kept only then this happening would be a case of the concept of control.
Letâ€™s have a simple example. I am playing music through an amplifier which has a volume knob. I affect changes to the volume level by turning the knob – and I affect the turn of the
knob by ussing my finger muscles. Now if I have in my mind (or in a dB meter) a reference level for the music volume then I control the volume by affecting my fingers and by them the turning of the knob. Her I do not control my fingers or the knob – it is absolutely
insignificcant to me how they change if only the music level becomes just right. But if I have in my mind (or in paper note) a reference value to the knob, say 7, then I control the knob position by affecting my fingers and I affect and stabilize the music
to some level by controlling the knob. But in a similar way also here I have no reference values foe fingers or music volume.
An now we must forget that example, because there are no reference values in the environment – aand we have no reference values for the variables in the environment. We have only reference
values for the perceptual signals. That is why only perceptions (actually perceptual signals) are and can be controlled – accordiing to PCT if I have understood it at all. Everything else than the perceptual signal is affected, adjusted, changed, kept, stabilized
or something else but not controlled. But the perception is controlled BY affecting, adjusting etc. those other parts of the control loop.
I do not want to change our everyday speech, but I hope that in so important theory as PCT, the theoretical speech could be strict and coherent – at lleast with the most central concepts.
Please, regard all my statements as questions,
no matter how they are formulated.

Aihe: Re: Behavior is Control (was RE: Mad idea?)
Hi Rick, that is a great answer. I think we can often get into tangles when we try to reapply our PCT operational definitions of everyday terms, like ‘control’ and ‘Behavior’ back into everyday language. It is almost as though we should
be explicit every time we use either ‘version’ in our explanations. Or maybe that we always use a technical term within the PCT model rather than the everyday term when we mean the PCT definition?

FN: Boris: I have a question for you regarding â€œbehavior is control.â€?
FN: I know you regularly take issue with Rick asserting that behavior is control but I wonder if you would
agree with this statement: â€œOur behavior serves to control our perceptions.â€?
RM: I think the problem here is with the word “behavior”. In PCT, “behavior” means what it does in common parlance: what we see people doing. In one of his papers Powers says that
when he talks about “behavior” he is referring to the things people do to which we give names (because we see them done over and over again). Some examples of behavior are “lifting a finger”, “writing an email”, “tying shoelaces”, “playing Go”, “voting”, etc.
In PCT, all behavior (except a muscle twitch or a glandular secretion) is both action and a controlled result of action. For example, what we see as “writing an email” consists of the actions (finger movements) used produce the email and the resulting
email itself (the controlled result of those actions).
RM: When you say "Our behavior serves to control our perceptionsâ€? you are using the term “behavior” to refer only to the actions that produce a result, the result being a perception
from the point of view of the person producing it. That is, you are privileging the “action” view a behavior over the “result” view. For example, take the behavior of “tying shoelaces”. You can say that this “behavior” consists of the actions (movements)
that result in the tied laces; but you could also say that this behavior consists of the tied laces that result from these movements.
RM: Saying that “behavior is control” simply calls attention to the fact what we call “behaviors” are both actions and results; in PCT lingo, behaviors are both
outputs and the variables controlled by those outputs – controlled variables . So the behavior called “tying shoelaces” points to a control process where the controlled variable is the state of the laces, the reference state of this variable is
“tied” and the outputs that produce this result are the hand movements the get the laces tied. Moreover, what we see as the output component of a behavior are typically controlled variables themselves and what we see as the controlled variable component of
behavior is typically an output itself. For example, the movements (outputs) used to produce the reference state of a controlled variable (tied laces) are themselves a controlled variable; their speed and direction are the controlled result of muscle forces.
And the tied laces (the controlled variable) that result from those outputs (movements) are themselves outputs that are the means of controlling another variable, the “onness” of the shoes.
RM: So “control” is just a more precise definition of the informal term “behavior”. “Control” refers to the observation of a variable being maintained in a reference state, protected
from disturbance. And this is what we can see is what is going on with the things we call “behaviors”. “Tying shoelaces”, for example, refers to the observation that a variable (the state of the laces) is maintained in a reference state (consistently brought
to the state “tied”) protected from disturbance (the different initial state of the laces, variations in the forces the affect the laces, etc). When you are able to see behavior – any named behavior – as being both output that affects the state of a controlled
variable and a controlled variable itself – you have learned to see behavior through control theory glasses. By the way, this is all discussed in the first 2 chapters of “Controlling People”.
RM: Bill called his book “Behavior” The control of perception" because psychologists are familiar with the term behavior; it is what psychologists study. But the first thing Bill
talks about in B:CP (as we do in “Controlling People”) is the fact that behavior
is control. So Bill could have called the book “Control: The Control of Perception”,describing the fact that what is in the book is a theoy (control of perception) that accounts for the controlling we see as behavior. But that would have been rather
confusing to people who didn’t already know that behavior is control. So I think the actual title of the book, “Behavior: The control of perception”, is perfect as is. And I especially like Martin’s way of reading it (since it’s the same way I read it):
MT: A colon is sometimes used in English where one might use “is”, often in a title, for emphasis. So I read that title as saying quite directly that “Behaviour is control” (of perception,
