The vast majority of psychologists, whatever their area of
interest, are Cognitivists. Even the modern fad for Evolutionary
Psychology is based on Cognitivism.

There are some exceptions - in perception research there are the
Gibsonians, for example, and psychophysics owes little or nothing
to Cognitivism. And there are the applied social psychologists,
who try as hard as possible to be completely atheoretical. But
these are very much the exceptions, not the rule.

The file drawer effect does not allow for falsification. It
isn't intended to - it's purely a way of correcting the
statistical significance of a result by estimating the number of
unpublished studies. It does nothing to address the problem that
negative results are by definition non-significant, which means
the underlying theory is not falsifiable even in principle.

Where exactly did I make Operationalism out to be some sort of
demon? Of course it is used in the physical sciences - it was
invented by a physicist, P W Bridgman.

But what psychologists are actually doing when they claim to be
using operational definitions is both confused and self-
contradictory. In psychology an "operational " definition is a
proxy for some other quantity which cannot be directly measured
and which has no rigorously defined relationship to the proxy.
This is absolutely not what Bridgman meant by an operational
definition.

It has a lot of evidence backing it up if you accept the
premises by which that evidence is interpreted. If you challenge
these premises - as for example the Gibsonians have been doing
for thirty years now - you find most of that evidence disappears
like mist.

Of course the human visual system makes mistakes - but the
errors are specific to the circumstances which produce them. And
in the case of perceptual experiments those circumstances are
_designed_ to be highly contrived and unrepresentative of normal
life because that's the whole point of experiment; to be able to
control circumstantial variables in a way that can't be done in
vivo.

But Cognitivism is based on the assumption that the brain
doesn't extract information from the visual world because there
is no information there to be extracted. Instead the brain is
assumed to interpret the visual world by means of a sort of
elaborate guesswork. In other words, Cognitivism assumes that
the visual system is highly fallible right at the outset and all
experiments are interpreted as yet more evidence of that
fallibility. But change the assumption, and the evidence ceases
to support that conslusion - which is something J J Gibson
realized more than thirty years ago.
