I’m sure PCTers can help me out here.
If somebody was to make a PCT-informed pitch to a certainPresident about global warning, what could be the gist of
for and against arguments in a (reasonable) debate?
Your question echoes one of my reasons for being dissatisfied with
the psychology I was taught so many years ago: “If psychological
theories are correct, why aren’t psychologist placing themselves in
positions where they can influence the world for good, fix crime,
avoid war, etc. etc.? They surely have the know-how to get
themselves into positions of power where they could put their
theories into practice, don’t they?”
But they don't. Do we who understand PCT? Or does PCT suggest why we
would not or could not do that?

Bruce, I largely agree. Some commentsthough:

Beginwith some PCT truisms.
Allthat we can know of our environment is our
perceptions of it.
Â
(Not sure about this, but I will turnto it sometimes later – it depends on definitioons. I
agree that all our knowledge is based on
perceptions.)
Â
Allthat we can control of our environment is our
perceptions of it.
Â
That is funny and fuzzy saying, atleast for me: sounds like our perceptions were in
the environment. I would say that we cannot control
anything in the environment but only our perceptions
of it.
Â
Icontrol many perceptions of our environment
without exerting the actions that maintain them
under control. Other people, or other agents,
exert the actions that maintain them under
control.Â
Â
Or they just happen to be (temporarily)so that our perceptions of them remain near the
reference.
Â
Amongthe evidence that I control such perceptions is
the observation that, should control of them
lapse, I act in such a way that other people or
agents resist the disturbance and re-establish
control of them.
Arecent example: the street signs for Pinehurst
Avenue and Chase Road were swapped, so that each
designated the other road. My wife called my
attention to it. We contacted the Public Works
Department. They fixed it.
What'sthe point of this? All that we can know of our
environment is our perceptions of it, and we
presume that our perceptions are the realities
that we perceive. (We presume this even though we
know that our perceptions are selective and omit
infinitely many aspects of the environment, some
of which we know about because we or others have
extended the senses with scientific instruments.)
This presumption is justified by our success
controlling in the environment and by the like
success of all our human and pre-human ancestors
without whose survival we would not be here.
Â
That is extremely important. Oursuccess in control of our perceptions is highly
depending on other people and other actors – and
finally on the objects or our perceptions.
Â
Bythis justified presumption, we project the
universe of our perceptions into the otherwise
unknowable universe of our environment.
Â
Thatjustified presumption extends to the fact that all
that we can control of our environment is our
perceptions of it. We are justified in the
presumption that the controlled variable is in the
environment. Every time two or more of us control
what we perceive to be the same variable in the
environment we obtain further justification of
that presumption. Examples of two or more of us
controlling what we perceive to be the same
variable in the environment are conflict,
collective control, and the Test for the
Controlled Variable.
Â
Here I disagree. This is a naturalpresumption of our everyday life. But I think that
PCT just makes us abandon that presumption at least
in theoretical i.e. scientific context. In everyday
talk and thinking we may say that we control
something in the environment and that something is
possibly controlled also by some other person. But
we should know better that we and those other
persons are controlling only our or their own
perceptions and nothing in environment. That object
or something in the environment OF which our
perception is may be the same OF which the other
persons’ perceptions are. But we do not control that
object or whatever there is in the environment but
just our own perceptions.
Â
Weroutinely forget that this is a presumption, and
we are justified in doing so.
Â
No, we are not justified in doing so ifwe are scientifically studying “behavior as control
of perception�.
Â
It isimpossible to argue whether or not the controlled
variable is in the environment without forgetting
that we make this presumption, and that it is a
presumption. If we accept the justification (which
we must, in order to do things together, including
arguing, and which we routinely do to survive)
then we thereby assert that it is in the
environment. But when we wish to identify things
in a control theory diagram as a tool of analysis,
we remember that this is a presumption, merely the
projection of our perceptions onto the otherwise
unknowable environment, and we must acknowledge
that it is in the perceived environment, the
universe of perception, which we perceive to be
shared between and among us, and really out there,
largely because of the routine successes of
collective control.
Â
Yes that is right, I agree with this.
Â
I knowof no way out of the conundrum other than to
acknowledge it. I believe it is foolish to argue
about it.
Â
The only way out perhaps is stayingstrict and careful with our concepts. We must tell
when we use every day “control� and when PCT
“Control�.

Martin - I am confused because yousay:
Â
MT: Rick says the controlled variableis in the environment, which I say cannot be true,
because in the environment there exists no
independent reference variables nor sources from
which they can be determined independently of
observation of the moment-by-moment values of the
environmental variable itself.
But then Rick responded to me in thePCT Research thread:
Â
RM: The controlled variable is not inthe outer environment; rather it is a function of
physical variables that are in the outer
environment; the function is called a perceptual
function.
Â
Â
I construed that sentence from Rickto be a shot in a different long-standing and
apparently irresolvable argument, which I had
intended to ignore. I realize there’s no point in
reiterating the fact that the result of applying a
function to a bunch of variables is itself a
variable, but that’s the nub of the argument in
which that sentence was a shot. Rick disagrees –
it’s mathematics and therefore just an opinion
open to contradiction.
Â
However, to me he certainly suggestsin that sentence that the controlled variable is
in the environment, whether it is a function of
other variables in the environment (presumably
controlled ones) or should be treated as the
result of that function. Certainly the function
that defines the CEV is the perceptual function.
We have never had any disagreement about that. The
question is whether the arguments to that function
are in the environment as he explicitly says they
are.
Â
But consider instead Rick's recentstatements about “behaviour”, which provide the
context for interpreting the sentence you quote
[From Rick Marken (2017.06.06.1225). I have
highlighted a few phrases and sentences. I don’t
think I need more than this, though I could go
back into the archives and find interactions
between us when Rick has argued against me that
the controlled variable IS in the environment,
quite explicitly. Yesterday’s message should be
enough to make the point:
RM: Â Saying that "behavior iscontrol" 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.
Â
RM: So "control" is just a moreprecise 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”.
Â
MT. In all of that is there anysuggestion that a controlled variable might be a
perception? I think not. Everything refers to the
controlled variable being a state of the
environment that can be observed by another
person. In those two paragraphs, the only
reference to perception is in the “P” of “PCT” up
front. If Rick had said, for example, in the
second highlighted clause “the controlled variable
is the [perceived] state of the laces”, I would
have no problem. But he didn’t, and any casual
reader might think he meant (and maybe he did
mean) the actual state of the laces in the
environment.
Â
MT. We all know the form of thecontrol loop, at least in its simplest “canonical”
form. We also know that real organisms have
limitations such as sensory thresholds, which mean
that any particular value of an external variable
gives rise to an uncertain value of the perceptual
variable that is produced by its perceptual
function (actually a hierarchy of perceptual
functions), and we know that neural firings are
actually not a continuous smooth “neural current”.
What we also know is that the reference value for
a perceptual signal is generated from within the
organism, and does not exist in the environment
(contrary to what Rick seems to imply in the
fourth line of each paragraph). Control of a
perception may not even correspond to control of
anything another observer could perceive in the
environment, if the perception includes any
component from imagination.
Â
MT. It seems to me that regardless ofwhat may be in Rick’s mind (and he agreed with me
the other day about Behaviour being the control of
perception), the words he uses can easily lead a
reader to conclude that controlled variables exist
in the environment. I would like to keep clear
that however well the perception corresponds to a
state of the environment, it is not the state of
the environment, though it is the state that is
controlled. To confuse the two
is…confusing.
