Knowledge Objects as a
Dangerous Idea

An idea that is not dangerous is unworthy of being called an idea at all

Oscar Wilde

When one dares to say that world is “simpler than that” one might hear
(in a thought balloon) “how odd, I thought that knowledge and
information is increasing without limit”

My career as a Management Scientist and as a CyberEducator (a label
by Newsweek) gradually convinced me that simple forces were being
viewed too much together and that underneath is a simplicity. Some of
my MIT colleagues were quite surprised by the notion

As for you, Bateson and Watzlawick of the Palo Alto Mental Health
Institute said when communication fails, there are thoughts of “madness
or badness” by the recipient about the sender (this speaker)

I hope to dissuade such thoughts by making “knowledge simplicity”
convincing by relating some relevant experiences

Sounds Complex?

Confirmation of a Near
Isomorphic Model

Based on the data regarding 24 thousand accidents over a two year
period, and constructing this model in 3 man
months, a reduction of
3530 accidents (14.7%) involving mortality, morbidity and property
damage was predicted by adding a locomotive strobe light to the

Three years later the US Department of Transportation’s
Transportation Systems Center conducted field tests of strobe lights
on locomotives and the field study found accident reduction to be
15% at a 95% level of confidence

The high correlation between these two numbers, 14.7% and 15%
suggests that the model was truly near
isomorphic to the system

US industry exposing works argued for 200 ppm.

OSHA pressed for 100 ppm.

Our (Fortran) model so completely explained variances in blood
lead levels that OSHA regulation was set at 50 ppm.


1. The flows in the biological model were published in a Harvard University

2. Flow rates were simply related to amount of lead on each side

3. Creating a work week of workers exposed to lead was just hours of the day

things look complex

System Dynamic Models of simple processes are easily evaluated

This iThink System Dynamic Model used linkages among poorly defined
parameters that produced reasonable system response over time, but was pre
determined by initial settings and parameter constraints

Such modeling, however, has been found to be extremely valuable for learning
purposes whereby within the “learning organization,” actual decision
makers can
make up for the shortfalls of such models

Knowledge Objects as Necessary to Advance
Systems Dynamics and the Systems Approach

For true "systems dynamics"

you have to have, not just the learning
organization, but a learning Net of knowledge objects


class libraries associated with 3GLs


4GLs are created for specific audiences, such as financial
accountants 5GL

But whether as Dynamo or iThink or MATLAB, they either have
found a specialized nook, such as engineering simulation models, or
they are unfortunately too homomorphic

Missing has been the paradigmatic genesis of the Singer/Cowan/
Churchman/Ackoff legacy in creating operational definitions as
knowledge objects

Apparent Complexity

As we know by combinatorial math, for each knowledge axis (where we
define these by dissecting selected books* and creating multiple
matrices), and for the resulting N
, N
, N
, etc. knowledge states, we see
apparent complexity

becomes large by the multiplication of all these
possible states, i.e.,
Apparent Complexity

= N

x N
x N

x …

But, this does not mean that the
actual complexity

is high.

Definition of Communication within a
Purposeful System

: One purposeful individual (B) communicates to another (A) when a message produced by B produces a change in
one or more of the parameters (P
) of A’s purposeful state. B can be referred to as the

and A as the

Ackoff, p. 142


probabilities of choice


efficiencies of his choices



relative value of the possible outcomes

Notice: if B produces no change in A’s purposeful state, then no communication has occurred.

For example, if B sends A a message which is communication, and if B resends the same message again to A, and if this message


wholly redundant, the second message is not communication.

Mathematical theory of communication: tells us how many bits of information can be sent per second over perfect and imperfec
communication channels in terms of rather abstract descriptions of the properties of these channels.

Shannon in J. R. Pierce, Symbols, Signals and Noise: The Nature and Process of Communication, 1961, p. 8

Pierce could not define communication for purposeful systems as he mostly confined himself to symbols, thus when a
individual (B) communicates to another (A) the “aim and outcome of communication” is only that A resolve uncertainty in the w
that B
made choices of symbols when composing the message (addressed as “Entropy” in ch. five).

J. R. Pierce, Symbols, Signals and Noise: The Nature and Process of Communication, 1961, pp. 78

As for addressing a purposeful system, Pierce tackles that in two chapters just after “Cybernetics” (ch. 11) in “Information
ory and
Psychology” (ch.12) and “Information Theory and Art” (ch. 13) in which he boldly addresses music and musical scores but he ca

useful formulations as he is absent the requisite operational definitions.

: A communication that produces a change in any of the receiver’s probabilities of choice informs him, and hence
transmits information.

Ackoff, p. 144

Complementing this regarding C

(set of available courses of action, a.k.a choices), for changing E

(set of the individual’s efficiency to
produce outcome O
, having a set of choices, C
) we have:

9.11 Instruction: A communication that produces a change in the efficiencies of any of a receiver’s courses of action instru

him, and
hence transmits instruction.

Ackoff, p. 144

And complementing 9.10 regarding this regarding V

(the value of the outcomes to A) we have:

9.12 Motivation: A communication that produces a change in any of the relative states the receiver places on possible outco

(the O
of his choice motivates him, and hence transmits motivation.

Definition of Information in a Purposeful System

n: Frequently the messages have meaning; that is they refer to or are correlated according to some system with certain physi

conceptual entities. These semantic aspects of communication are irrelevant to the engineering problem. If the number of mes
es in the set
is finite then this number or any monotonic function of this number can be regarded as a
measure of the information

produced when one
message is chosen from the set, all choices being equally likely.

C.E. Shannon, "A Mathematical Theory of Communication",
Bell System Technical Journal
, vol. 27, p. 379, July, October, 1948

Information: … multifaceted term … [o]ne side, at least, has been polished by mathematics, whilst other sides (semantic and
aspects) are beginning to show up, though these other aspects are not, as yet, truly distinct or clear.

Regulators: How near
isomorphic is required

, in:
International Journal of System Science
Vol. 1 No 2 (1970) 89

A model that incorporates all dominant variables affecting state change
and ignores all insignificant variables is sufficiently isomorphic (i.e.

So in models involving human behavior, if individual variety is fully
captured if statistical aggregates suffice

In such cases differences in individual variety can be viewed as
“apparent complexity”

Social Regulations as Good

Statistically, individuals, as a lot, demonstrate serious
choice errors involving situations having high risk and low

This was understood both within the US legislative process
for health safety in the 70’s and 80’s, and in the literature,
e.g., Howard Kunreuther and Paul Schoemaker in the early

For example, warranted the intrusion of public regulators
in the form of highway/railroad grade crossing protection

in the form of occupational safety in lead using industries

variety that matches the variety of the learner or groups of learners with
group variance, e.g. differentiated instruction

provide standards for structural concepts

E. O. Wilson wrote
Consilience: The Unity of Knowledge
, 1992, which

appears to promise a scientific perspective on knowledge at the operational level

However, each time Wilson broke ground towards operational definitions, he hesitated
and called such items part of a folksonomy

an informal way that people tag

This word now is liberally used to refer to the use of "tag clouds" on the Internet

This is because there is no widespread awareness of operational definitions and thus
about knowledge objects, the Net is riddled with a multitude of haphazard tags.

The same can be said for what the W3C [consortium] and their focus on the
"semantic web”

The general direction of this focus sounds encouraging

But it reflects no knowledge of the existence and/or the value of more consistently
using defined knowledge objects.

I.e., they are doing the best they can within an overly complex and haphazard

Finally, Reusability

There are no problems with library reusability at the 3GL level

At the 4GL level there is high vendor dependency

Beyond 4GL there are huge reusability problems

However, way beyond those facilities we have reusability as language dictionary words

To bridge the gap, by stripping down dictionary words and creating operationally
defined Knowledge Objects, reusability is established

Dictionary level granularity for

Knowledge Objects, Part I

Controlled vocabularies are typically unsuccessful unless at the
level of words and word definitions.

So. The operational definition of a knowledge object is equivalent
to a dictionary such as the American Heritage Dictionary. That
dictionary is to be preferred over Webster's, etc., as it is more
modern and many of the words are more operationally defined
than in prior efforts.

Dictionary level granularity for

Knowledge Objects, Part II

Imagine taking the American Heritage Dictionary and stripping out data

I.e., take multiple references pertaining to a knowledge object, such Mammal,
and leave those as the properties of the object mammal

Presto. We have reduced apparent complexity

This can be imagined by viewing the "mammal tree" in the next figure

While this tree traces the development of mammals over time, if viewed from
right to left (many mammals back to a first mammal), it is comparable to
viewing the list of mammals on the right as ”methods" of the knowledge
object Mammal’s “property” of species

In this way, a single entity suffices to encompass all mammals

It is only when distinctions need to be made across ”method species" that one
need examine and expose the apparent complexities of the multitudinous
varieties of them
