[net.misc] REAL Sciences Don"t Eat Quiche

	Begging to disagree with you but I dont think that it is fair to
assume that I have no interest in human beings because I have no faith in
today's psychology.  Indeed, it is precisely because I care about human
beings which makes today's assessment of psychology so frightening.  I
am very worried when people abdicate their responsibility for their own
lives and instead rely on their neighbourhood 'shrink'.  Not only are they
missing out on a wonderful if difficult experience, but they are also
likely to get *inaccurate*, *misleading*, and possibly *dangerous*
advice.  If, when, psychology becomes a quantitative science it will do
untold good for mankind if used properly (though it is sobering to think
how our ideas must change to accept the ability to in some way determine
the activities of others with more than just a hope of success), now, as
it stands, it can not fail to do harm.
	The comparison with the unified field theory is not apt -- it
is better to compare today's psychology with the alchemy which lead to
chemistry.  It may have been the most scientific thing going at the time,
and useful results have come from the results of the ancient alchemists,
but some of the potions recommended on the search for the philosopher's
stone make today's chemists shudder at the dangerous and useless 
substances actually produced.
	If I came up with a unified field theory which ignored or
denied known physical laws such as conservation of mass&energy, or which  
proved that the law of gravity was a figment of our imagination, you
would have little trouble proving me wrong.  The foundation of physics
is the repeatable experiment.  Matter and energy are not suggestible,
they obey certain laws, and behave in accordance with those laws.
	Psychology today is very different.  Very different theories such
as SOCIOBIOLOGY and SKINNERIAN BEHAVIORISM have enough statistical
evidence to 'prove' them.  Freud and Jung have various theories, and their
followers elaborate on them and form semi-freudian and pseudo-jungan
theories.  Alas, no synthesis is possible because to much of the various
beliefs are mutually exclusive.  This does not stop people from relying
on their 'shrink' who 'must know everything because he is a doctor'.  This
does not mean that psychology is not a poor field for research, the
converse is true.  But is does mean that the man who implicitly trusts
his 'shrink' runs the same risk as the man who believes my new field of
physics which omits the law of gravity -- if he tries to fly out of his
apartment building he is in for a rude shock at the very least.
	Given a large enough sample of people it is possible to draw
a (probably) infinite number of contradictory conclusions.  Nearly every
theory of psychology has had some merrit -- but how much it is currently
impossible to judge.  Thus while it sounds very attractive to say that
'computers are ruining society because they limit our contact with real
human beings' all in all it boils down to a statement of faith.  Either
you believe it or you dont -- and you will find evidence to support your
position if you look hard enough.  My question is whether such a field
should have been unleashed on an unsuspecting and uncritical public,
especially as a 'science', since the average soul has demonstrated that he
may not differentiate  between Physics and Creation Science. The question
now is academic -- the 'shrink' is well-rooted in contempory society --
But now that they have, do we who know better have an obligation to bring
this view of psychology to the public eye?  If so, 'computer addiction'
may be a good place to start.	Currently I do nothing, out of respect for
my fellow man's ability to do what he pleases as long as it does not harm   
others.  But if a large group get together and try to save me from my
computer I think that it will be time for me to save them from their
unquestioning belief.

Indeed, Psychology, like all other forms of Human Endeavor is prone
to error.  That, in and of itself, is not damning.  What *is*
alarming, as Ms Creighton points out, is the unquestioning acceptance
(read: Faith) that the public puts in psychology and its practitioners.

Leaving aside the damage that can be done in a clinical setting, the
June issue of "Science 82" contains several articles describing the
growing use of "forensic psychology."  Here the public's faith in the
absolute judgement of an *extremely* inexact science is taken to its
ultimate, tragic consequence.  The use of *expert witnesses* to speak
on the state of mind of a defendent in a capital case is a very risky
business.

As the article pointed out, even most psychologists are uncomfortable
with the public's (and the court's) view of psychology's role in
criminal justice.  What is needed, both here and in many other arenas
of public life, is a sense of healthy skepticism - founded in an
understanding of the limitations involved.

Before settling into graduate school in computer science, I had the
opportunity to be part of a modern psychological research laboratory,
and based on that experience I can say without qualification that
psychology is a science in the strictest sense.  Psychology uses some
of the most sophisticated models and paradigms of all of the sciences.
Where most sciences are still tied to Vary One Thing at a Time,
psychologists use powerful multivariate experimental designs.  And
schematic models of reasoning, which have just been discovered by
workers in Artificial Intelligence, were invented by a psychologist
a hundred years ago (Bartlett), and have been quite valuable ever since.

I believe the authors of some of the recent flames about psychology are
confused about two things.  First, they think that clinical psychology,
as currently practiced, has much to do with the science.  As far
as I can see, this is simply not the case.  Experimental and cognitive
psychologists have successfully discovered many of the properties of
some of the subsystems of the human information processing system,
including parts of the visual processing system, auditory processing
system and various components of the memory systems.  What they simply
do not have, is much understanding of how mental illness works, or
whether it is appropriate to describe it as an illness.  (Actually,
a number of disorders involving organic damage have been well explained
by psychologists and neurophysiologists.  It is the functional disorders
that are mysterious.)  To the extent that experimental and cognitive
psychologists do have something to offer to clinical practitioners,
the latter are often not aware of it.

Second, many people have been taken in by the recent (well, up to
about ten or fifteen years ago) American obsession with Behaviorism.
How this strange theoretical framework came to dominate this continent
is of some interest to historians of science, but modern psychologists
are simply glad that behaviorist theories have finally been abandoned
as unworkable.  It seems that the computer metaphor had a lot to do
with the abandonment of behaviorism, but this does not explain why
Americans got into it in the first place, whereas others did not.
(The most recent psychological models show a picture of the human
information processing system quite unlike that of the modern computer,
but for a period of about five years, the computer was a very important
metaphor for psychological theories.)

I am happy to say though, that although there is much misunderstanding
of psychology in many quarters, this is not the case with the best
people in artificial intelligence and neurophysiology, who have
cooperated with cognitive psychologists, cognitive anthropologists and
several other cognitive disciplines to form the productive new field of
cognitive science.

So please don't quote Freud, Jung, Skinner, or Psychology Today as an
example of why psychology is a "soft science", lest I begin to quote
Kepler, Priestley and Science Digest as an example of why physics and
chemistry are a combination of magic and alchemy.  (I'm sorry, but I
can't think of any really awful recent physical scientists, although
I'm sure there are plenty.  I can think of plenty of non-recent good
psychologists, though; for example, Bartlett, James and Piaget.)
