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?

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”
“ 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

“ . . 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.

from Paradigm Shift . . . whose getting there? asks
this:
Now, how will things play out, if this sort of perceptual
impasse is deeply embedded, and discourse, at the level of
peer review, or within a university setting, is subject to the
imperative of “consensus building” in Kay’s sense of evasion
of controversy? Problems that may look easy from a distance
may be insoluble according to ordinary usages.
In difficult cases, it may be very much worse, because the
anomaly may couple strongly with power relations in the
invisible college responsible for decision. rshowalter Sat

Here I quote from #74, this thread, citing Adolf Berle's
POWER . Among Berle’s "Five Natural Laws of Power,"
there is rule three:
Power is invariably based on a system of ideas or
philosophy. Absent such a system or philosophy, the
institutions essential to power cease to be reliable, power
ceases to be effective, and the power holder is eventually
displaced.
If an anomaly undermines a system of ideas or philosophy,
there may be emotional reasons, coupled with and reinforcing
the conceptual reasons Kuhn cites, to not see, or refuse to
see, a basic point.
In the sciences, knowledge is property, and connections
between ideas, status, and power are close. This is true for
both individual scientists and scientific groups. . . . .
. That's true in business, politics and
everywhere else humans interact, too. Connections between
ideas, status, and power are close.
