Technology has always found its greatest consumer in a nation's
war and defense efforts. Since the last attempts at a "Star Wars"
defense system, has technology changed considerably enough to make
the latest Missile Defense initiatives more successful? Can such an
application of science be successful? Is a militarized space
inevitable, necessary or impossible?

Misunderstandings occur, including misunderstanding that are
entirely sincere. They can be very important. But they can be
resolved. To illustrate some difficulties that can happen, and how
resolution occurs for real human individuals and groups, I’m quoting
here from THE STRUCTURE OF SCIENTIFIC REVOLUTIONS 2nd Ed. by
Thomas S. Kuhn, , at the end of Chapter 6 “Anomaly and the
Emergence of Scientific Discoveries” The perceptual problems
described here can and do occur on the issues that divide the US,
Russia, and the rest of the world, though they aren't the whole
story.
“ To a greater or lesser extent (corresponding to the
continuum from the shocking to the anticipated result), the
characteristics are common to all discoveries from which new sorts
of phenomena emerge. Those characteristics include: the previous
awareness of anomaly, the gradual and simultaneous emergence of both
observational and conceptual recognition, and the consequent change
of the paradigm categories and procedures often accompanied by
resistance. There is even evidence that these same characteristics
are built into the nature of the perceptual process itself. In a
psychological experiment that deserves to be far better known
outside the trade, Bruner and Postman asked experimental subjects to
identify on short and controlled exposure a series of playing cards.
(J.S.Bruner and Leo Postman “On the Perception of Incongruity: A
Paradigm,” Journal of Personality, XvIII (1949) 206-23 ) Many of the
cards were normal, but some were made anomalous, e.g., a red six of
spades and a black four of hearts. Each experimental run consisted
of the display of a single card to a single subject in a series of
gradually increased exposures. After each exposure the subject was
asked what he had seen, and the run was terminated by two successive
correct identifications.
“ Even on the shortest exposures many subjects identified most
of the cards, and after a small increase all of the subjects
identified them all. For the normal cards these identifications were
usually correct, but the anomalous cards were almost always
identified, without apparent hesitation or puzzlement, as normal.
The black four of hearts might, for example, be identified as the
four of either spades or hearts. Without any awareness of trouble,
it was immediately fitted to one of the conceptual categories
prepared by prior experience. One would not even like to say that
the subjects had seen something different from what they identified.
With a further increase in exposure to the anomalous cards, subjects
did begin to hesitate and to display awareness of anomaly. Exposed,
for example, to the red six of spades, some would say: “That’s the
six of spades, but there’s something wrong with it- the black has a
red border.” Further increase in exposure resulted in still more
hesitation and confusion, until finally and sometimes quite
suddenly, most subjects would produce the correct identification
without hesitation. Moreover, after doing this with two or three
anomalous cards, they would have little difficulty with the others.
A few subjects, however, were never able to make the requisite
adjustment of their categories. Even at forty times the average
exposure required to recognize normal cards for what they were, more
than 10 per cent of the anomalous cards were not correctly
identified. And the subjects who then failed often experienced acute
personal distress. One of them exclaimed: “I can’t make the suit
out, whatever it is. It didn’t even look like a card that time. I
don’t know what color it is now, or whether it’s a spade of a heart.
I’m not sure now what a spade looks like. My God!” In the next
section, we shall occasionally see scientists behaving this way,
too.

“ Either as a metaphor, or because it reflects the nature of
the mind, that psychological experiment provides a wonderfully
simple and cogent schema for the process of scientific discovery. In
science, as in the playing card experiment, novelty emerges only
with difficulty, manifested by resistance, against a background
provided by expectation. Initially, only the anticipated and usual
are experienced, even under circumstances where the anomaly is later
to be observed. Further acquaintance, however, does result in
awareness of something that has gone wrong before. That awareness of
anomaly opens up a period in which conceptual categories are
adjusted until the initially anomalous has become the anticipated.
At this point the discovery has been completed. . . . . “
(End of quote from Kuhn)

Both Russians, Americans, and others can have perceptual
difficulties of this sort. They can occur, for different reasons, on
all sides of a controversy -- so that everybody misunderstands a
great deal (and misunderstandings don't match.)
At the same time, when everyone involved is looking at the
same facts - - - and when people have time, when they are
"connecting the same dots" they will come to agree about
basic, clearly observable things.
Sometimes not easily. Not always about everything. But people and
groups, who feel an obligation to share the same facts, can resolve
many differences, and be clear about others -- usually enough to
avoid bloodshed, and permit cooperation on specific things.
Sometimes, when facts are set out -- it can become clear what is
a misunderstanding . . . and what is based on fraud .
On issues of missile defense, the question of fraud, and other
forms of systematic deception, aren't the only questions. But they
are questions that need to be adressed.
