Phew!, Glad we were able to avoid any unintended conflict.

I agree that everything that is said and done is ambiguous. This is
Marken's Maxim: you can't tell what someone is doing by observing what
they're doing.

Bruce, I believe it's a great deal more important then this statement
"appears" to make it. Btw, I will use quotes in their normal context, that
is, words or phrases that _probably are_ "ambiguous" ( i.e. not that they
necessarily have different meanings in the dictionary, but have different
"working understandings" for different people ). These are words and
phrases that conflicts and disagreements will usually center around because
of their multiple understandings.

Argyris and Schon have perfected what they call a *double loop* "learning"
theory. It basically involves asking clarifying questions and going up
levels based on those answers. Argyris calls going up a level, going up the
*ladder of inference*. It is not a one to one transformation from HPCT, but
basically each level (rung of the ladder ) adds additional "meaning" to
original ideas and concepts beginning at the bottom rung. The concept being
that our "meanings" for "ideas", "thoughts", etc. are "built" from our
perceptions ( my use, they would say view of the world ). From this notion
flows some _very_ interesting empirical data collected over 30 years and
thousands of people. They have not, in 30 years been able to _disprove_
their theory. They also have never been able to explain why it works the
way it does. They simply describe what they find.

When we "observe", in this case either listening or reading, we
"understand" what we are hearing or reading based on _our_ perceptions, not
the talkers or writers intent. Unfortunately this simple fact is often
overlooked. Most of us ( me being a big culprit ) come charging out of the
box without _clarifying_ the _intent_ of the sender of the information.
When in face to face conversation this becomes a wee bit easier because we
can see facial expressions, see body movements and utilize all of our
senses to better interpret our "perceptions" Over the net we can't utilize
any of our senses. Only our imagination.

Reading is a unique experience in many ways. We are asked to perceive and
understand things that must _totally_ reside in memory. _All_ of our
sensing receptors are useless except for our eyesight, which we use _only_
to perceive words. Intent and understanding must come from
memory/imagination. Control persists throughout.

Trying to have a conversation, i.e. interact with others, can become very
tedious if done correctly. When you ask questions it takes at least 4 posts
to move forward on a concept. 1) I recognize I need a clarification on a
word or phrase, so I ask the question, 2) The recipient then tries to
clarify and responds. 3) I get the response and agree that the point has
been clarified. I then, 4) respond and hopefully the "conversation" moves
on. What if you don't "get it" the first time? It can become _real_
tedious, real quick. So we usually side step this very important part of
"understanding" ( i.e. asking questions for clarification )`to get _our_
points across. We generally wind up talking past each other. Isn't there a
better way? I think HPCT shows us there is. Make your "goals" ( intent
) of the post explicit and _honest_, an abstract if you will. This will
eliminate the need to decipher intent and set the "tone" of the post, (
i.e. light, technical, very serious, obnoxious, :-), etc. ) 2nd, Lets try
to clarify with questions, even if we have to go off-line for some of it so
we don't clog up the mailbox's with exchanges between two people trying to
clarify one or two points. 3rd) Lets try to respect each of our
perspectives. ( collections of perceptions ) we may not agree with any one
person but we are not only entitled, but "forced" by nature ( i.e. HPCT )
to be that way. Sorry, I will _NEVER_ "understand" the world the way you
do, but I might find some of your "understanding" _very_ interesting,
useful and important, thus possibly changing the way I perceive something.
It happened with me and Bills work as well as others, why can't it happen
to others and with any other person?

Any takers?

Paraphrase is the best test of understanding. "In other words, blah blah
blah, right?" A few cycles back and forth in that manner and you can get
pretty close. But as you have demonstrated if you want to show that
misunderstanding is easy, well, that's very easy.

I agree completely. ( whatever that means. LOL )

What I hear you saying is

1. After writing a post we could go back and put a brief statement of purpose at the top. (In practice this can lead to revision and tightening up of the body of the post.)

2. We should ask questions seeking clarification. We could paraphrase what the person said and ask "Is this what you meant?"

3. We should show respect for the other person's point of view. You don't say what you mean by this, or how we should go about it. I think that (2) above is a very good way to show respect for the other person's point of view.

Yes.

Yes. It will clearly ( at least hopefully :slight_smile: ), focus the writer to
his/her intent of the post and as you suggest, could lead to revision and
tightening up of the post. I also believe that this will help readers of
the post perceive and understand the words in whatever "tone" has been set
by the "purpose". This would mean possibly including a short statement
about how we are feeling "emotionally" about writing the post if that
happens to be a factor. ( confused, angry, perplexed, happy, etc. )

2. We should ask questions seeking clarification. We could paraphrase what
the person said and ask "Is this what you meant?"

Yes. Great point about the paraphrasing. It's ok to take a hunch on what
you "think" someone intended to say. Paraphrasing it makes it obvious that
it was a hunch not an assumption (i.e. a given ). I love it. :slight_smile: *What I
hear you saying* is another excellent way to paraphrase

3. We should show respect for the other person's point of view. You don't
say what you mean by this, or how we should go about it. I think that (2)

I love this already. :slight_smile: That is _exactly_ what I intended with the
addition of;
\
I also think we can be more, "accommodating" to new comers on the list and
to PCT. There is no _one_ road to "understanding" PCT . It takes time, it
takes perseverance, it takes desire. We need to encourage those things in
others. We need to understand that _everyone_ needs to take their own path
to _their_ PCT "understanding". We can only do that if we don't invalidate
a persons existing perceived world. They must do that themselves. It's the
only way it can happen. PCT tells us so. To tell someone that they are
"wrong" is not a good way to influence friends. They perceive the world (
and PCT ) the way they do because of a very long convoluted road they have
traveled. It's going to get more, not less convoluted. :slight_smile: To say or think
that they believe in nonsense is also counter productive. We need to think
of more ways to get to some of the same points It is also counter
productive to tell someone who is serious about PCT that whatever they say
is ok. We need to be honest, firm and truly interested in "helping" someone
make the trip. We need to explain to people that "understanding" PCT is
going to take some adjustment on their part. They are going to, at various
times believe they "know" the theory, only to find out otherwise. Remember,
we all came from some place. This is not easy. PCT goes against the grain
of _everything_ you have been taught since you were a kid. People will not
give up their cherished beliefs without a fight. We don't need to
contribute to the mental convulsions going on in peoples heads. Being a
good teacher is real tough work and not everyone is cut out for it. You
need to have infinite patience and a real concern for others. An example of
what I am talking about might be helpful;

I am currently having discussions with a head researcher at a company that
produces heart rate variability meters and EKG's. They are interested in
"stress" and I approached the researcher with the possibility of helping me
in my research with regard to stress and HPCT. I sent him 2 of Bill's
papers and the arm demo from his web site and asked him to; a) look at the
error component of the model. My hypothesis is simple. "stress" = "error"
b) to please read the papers with the idea of asking clarifying questions.
Ask lots of questions. _Especially_ if you see a concept that you "think"
you understand but have a feeling you may not, c) although you are
interested in the "error" component, it is part of a continuous process and
can only be understood in the context of the whole. I also read one of his
papers. I "know" he would be "interested" in PCT if he understood the
model. I am waiting to hear from him. If I don't hear from him in a week I
will give him a call and ask if there is anything I can do. When he tells
me to leave him alone I will do just that. Until that time, I will be
persistent.

I am waiting to hear back from him.

Thank you Bruce. This post exemplifies my concept. I found your *purpose*
statement a bit trite, but sufficient. I referred back to it often to make
sure I was covering the points you mentioned. I also checked my responses
to my purpose statement and asked the question; Does this answer his question?

Good show.

I suspect that you have to be careful about what system you are talking
about. Consider driving to work when the traffic is "bad". Your control
of the automobile may be very good, i.e., error is minimal, but
perceived "stress" is high. Presumably you are also controlling some
perception such as "getting to work in time for the meeting" much less
successfully, so the error in this loop might be high. It is easier to
measure how well you are controlling the car than how well you are
controlling the perception of getting to the meeting on time, but error
in the former might show little correlation with perceived (or measured)
stress.

Marc Abrams ( 2003.05.01.1659) ]

Argyris and Schon have perfected what they call a *double loop* "learning"
theory. It basically involves asking clarifying questions and going up
levels based on those answers.

Purpose: Clarification

As a side-bar comment, "going up a level" (or down a level for that matter)
shows up in more than just PCT or in the work of Argyris and Schon. More
than 30 years ago, as part of my training as an internal OD consultant, we
were taught, in systems terms, that three levels of analysis usually
suffice. In systems jargon, these are (1) the level of the suprasystem,
(2) the level of the system being analyzed and (3) the level of the
subsystems of the system being studied. "Going up a click" was the
catch-phrase for getting "above" the problem so as to be able to look down
on it. "Going down a click" was similarly used when it was thought that
digging for detail would be helpful. Argyris was one of the OD gurus at
the time and was in fact involved in the Navy's effort to train internal OD
consultants (called "command development specialists").

There is, however, a big difference (or at least I see one) between the
notion of ratcheting one's level of analysis upward or downward in terms of
degree of specificity and climbing or descending A&S's ladder of inference
as well as a big difference between both of those techniques or methods and
"going up a level in the PCT hierarchy." All three seem to me to represent
very different analytical frameworks.

Marc: I find the practice of stating one's purpose at the outset of a
posting a refreshing and useful thing to do. Now to it:
What is or was your purpose in what I see as drawing a parallel between
A&S's ladder of inference and the HPCT hierarchy?

Purpose: To begin a dialogue with Fred N. ( and hopefully others ), with the
intent of clarification for both Fred and myself on the concept of Argyris

pointed out, he has seen in the literature.

Great.

Now to it:

What is or was your purpose in what I see as drawing a parallel between
A&S's ladder of inference and the HPCT hierarchy?

Your post addresses 2 of the many items I covered over the last couple of
days. I will address one of them now and hopefully 2 subsequent posts of
mine later today or early tomorrow will clear up the rest. I will
specifically address this question in my 2nd upcoming post, with the first
being on some additional "thoughts" and "ideas" about a PCT/HPCT lexicon and
a second post on HPCT.

The first problem has to do with the PCT/HPCT lexicon. As I said over the
past few days and began to address in my *Starting Over* post;

From[Marc Abrams (2003.05.04.1941)]. Most of what you spoke about are not
currently Technical words associated with the PCT/HPCT model. That is to say
your "concepts" and Bill's "concepts" and Argyris's "concepts" currently
have no common lexicon to refer to, only the metaphors we each walk around
with. We need to develop a lexicon of "cognition" for the HPCT model. It's
that simple. How do we know we are talking about the same things if we don't
have a common "anchor". You will find _many_ instances in the literature
where things "sound" PCTish. we need to define them in terms of an HPCT
model and add definitions or invent new ones, or use different words to
represent our "ideas" and "notions", all with the intent to suit our
scientific needs.

Do you agree or disagree with me on this notion? If you agree, no need to
acknowledge, If not please explain your reasoning behind your disagreement.

Catch you later. :slight_smile:

<[Bill Leach 940904.11:17 EST(EDT)]

[Rick Marken (940903.1100)]

I think we need to go up a level (or at least this we does).

I believe that there are people of "good will" and people of "bad will".
In addition, I believe that there are people of "no will" (that is they
neither try to hurt nor do they try to help others).

I also believe that no two people will exactly agree on the definitions
of such terms as "good will", "bad will", "hurt" and "help".

I believe that there are usually people on "all sides" of an issue that
are genuine in their expressed intentions. I also believe that there are
people on all sides of most issues that are not genuine but are actually
intentionally deceptive.

In addition, I also believe that most of the time (and particularly with
"big, media involved issues) I will not have the necessary information to
conclude for myself who is a charlatan and who is not.

In general, I do not "trust" the media at all. I do not even trust the
media to present the "facts" of a matter much less provide an objective
"commentary". In this, I doubt that anyone can "shake" this belief as it
has developed over some 30 years of personal experience with media
reporting. Now that does not mean that I believe that all reporting is
unduly biased or that no commentator ever provides a reasonable
evaluation. What it means is that I believe that unless you have
detailed personal knowledge of that which the media is reporting on, you
have almost no way to know the extent to which the information has been
"adjusted", intentionally or otherwise (and my own belief is that rarely
is such adjusting intentional on the part of the media itself).
Reporters and commentators are influenced by their own systems concepts
just as much as any of the rest of us.

I know that all of this sounds cynical and probably is, but I am just as
"bothered" by the politician or "consumer advocate" that tells me that
they "have only my best interests in mind" as I am the investment broker
that tells me the same thing.

Marc Abrams (2003.11.21.1706)--

Marc:

...why do different people have different 'tastes' in food, music, etc.

Me:

Different reference signals.

Marc:

If reference signals come from the hierarchy how do 'error' signals 'define'
such things?

A reference signal is a specification, in the brain, for the state of a perceptual variable, such as "acidity". If your reference for acidity happens to be set low, say at zero, then when you put an acidic lemon in your mouth, the resulting perception of acidity (say it's 6) will not be at the reference for acidity. The resulting error will drive actions aimed at bringing the perception of acidity to its reference level. This will involve actions like spitting out the lemon and washing your mouth out with water.

I think of error as an inverse measure of liking for the perception. We like a perception to the extent that it is at the reference. When a perception is at the reference, error is zero, so zero error is maximum liking for the perception. When a perception differs from the reference, error is greater than zero. The greater the error, the less the liking for the perception.

Since references change over time (to satisfy higher level goals, according to PCT), the same perception can be liked sometimes and not liked at other times. Sometimes you feel like (perceiving) a nut and sometimes you don't.

Are you actually saying that you and I 'perceive' the same tastes and sounds
and it's only because of different reference signals that we have such
diverse 'tastes' in things?

Yes. I think we all perceive (or can perceive) the same perceptual variables, like acidity, fairness, etc. So the difference between people in terms of their "tastes" for perceptions is (I think) a differences in references for those perceptions. I don't think we necessarily experience the same perceptions in the same way. This is what Bill was talking about. I think it's entirely possible that your experience of acidity is nothing like mine. But I think we do perceive in terms of the same dimensions of perception. We both know what each other are talking about when we talk about the acidity of lemons. The difference between us seems only that you dislike that acidity while I like it (at least, I like a higher level of acidity, in certain situations, than you do; I don't sit around sucking lemons but I do enjoy a moderately acidic lemonade occasionally). So it seems to me that the difference in people's "taste" regarding the same perceptions is largely a matter of a difference in their references for the preferred state of perceptual variables.

I suspect that you misspoke. There is, as you have pointed out, no
evidence that people have the "same" perceptions. Perhaps "similar" is

I think both of you guys and other interested party's should try this very
nice easy experiment. Take a any number of people (the more the better)
outside and as a group ask them to look around the environment you are in
for 30 seconds. Please don't be cute and do this either in the middle of a
desert or ocean :slight_smile: Then after ask each one to list 10 things they saw,
smelled, heard or felt in that 30 second time period. _DO NOT_ tell them
before hand you are going to ask them to make a list. Just ask them to have
a look around.

It has been shown _many_ times (I don't have the cites handy) that on
average people will mention 2-3 of the same items in a list of 10 and often
the 2 or 3 who do mention the same items will have 'perceived' different
aspects of those items upon further review.

I don't think there is not a snowball's chance in hell of people having the
'same' perceptions. But I
think Bruce is right on, in suggesting that similar (or 'in the ballpark')
are all that is needed in most cases for communications to effectively take
place.

Everything you have said in this post is useful, true and accurate for

model provides little or no insights into the 'chemistry' of PCT and it's
functions.

I also believe very strongly that your loose use of the word 'perception',
which according to you and Bill means anything and everything from a ray of
light to the planning a wedding, has and will continue to be a major problem
on Csgnet. Again, it might be ok with your current model but it provides a

Yes. They are "all the same" in the sense that the process is recursive.

Bruce Gregory (2003.11.23.0954)--

Yes. They are "all the same" in the sense that the process is recursive.

"Recursive" is a mathematical notion that unfortunately involves several
kinds of infinities. Any real implementation of a recursive process (as on
a computer) requires saving the state of the machine each time the
recursion is repeated, leading (except in a few special cases) to a
requirement for infinite storage capacity (known as stack overflow). And of
course since many recursions are basically infinite series (like
sin(sin(sin...sin(x))), they require either infinite time to be calculated,
or infinite speed to be calculated in a finite time.

My other objection to such "complex systems" ideas is that they are not
very good approximations to reality. Consider fractals. I'm sure you have
read about the way fractals describe coastlines or mountain skylines, which
are "self-similar" on all scales of magnification. Except that they're not.
If you get close to a real example of either kind of "fractal" landscape,
you find that its character changes completely. Instead of a continuous
irregular line, you start seeing granules, cracks, and other
discontinuities that do not look like the large-scale picture at all.
Fractals fit imaginary landscapes, not real ones. Nothing in the real world
actually looks like the Mandelbrot set.

I don't care much for the word "pattern" for the simple reason that it can
mean anything you want it to mean. If it were limited to the meaning of
"static pattern" (configuration) or "space-time pattern" (event), it would
mean something, but when used to mean "any regularity whatsoever," there is
nothing to which it doesn't apply, and it loses whatever meaning it might
have had. If the whole world turned blue, we would soon cease seeing blue.
If everything is a pattern, soon nothing will be a pattern.

OK, lets see. Here are 5 perceptions that do not look like patterns to me:

Squeeze.
Hurt
Green
Chocolate
Warm

Obviously I could name a lot more like these.

In addition to both of you gentleman being right, there is one other
property that all 5 perceptions Bill has listed here have. They are
_Cognitive constructs_. That is, they are 'interpreted' signals that we have
in memory. There is _NO_ level in the current hierarchy that we can 'know'
about 'non-cognitively' (I know it's not a word but it sounds good :-))
_EVERY_ perception is a cognitive construct, including _each_ level of the
hierarchy. In fact your hierarchy is a perception of a perception. :slight_smile:

Bill, Bruce Gregory is not referring to a single level model. It is
currently believed by many (myself included) that _all_ neuronal activity is
based on patterns of networked neurons.

I should have noted that the process is not one-level. The higher
levels consist of patterns of patterns.
