processes of social categorization, social identity and social comparison, as used
in
the theory,
cannot be conceived to originate outside of their social contexts. But they can also be shown to
function in some ways which are basically the same
in
group, inter-individual and even
non-social settings. For social categorization, this is the case, in some conditions, for general
judgement processes (e.g. Tajfel,
1959;
Eiser
&
Stroebe,
1972).
The notion of social identity is
based
on
the simple motivational assumption that
individuals
(at least in our culture) prefer a
positive to a negative self-image. The idea of social comparison originated with Festinger’s
fully
inter-individual theory
(1954).
In view of these important similarities between the
‘individualistic
’
conceptions of social categorization, social identity and social comparison and
those used
in
the presently discussed theory of inter-group behaviour, what is the nature of the
differences
between this kind of theory and others?
A
full description of these differences is obviously not possible
in
this paper (cf. Tajfel,
1978).
It will be useful, however, to outline the general structure which will help to locate the concepts
of social categorization, social identity and social comparison
in
the total pattern and show that
they cannot be considered, as they are by T
&
B, to be the core of the whole enterprise. Let me
state that the emphasis chosen here reflects my own views and need not be shared by some of
my
colleagues who have contributed in crucial ways to the development of our work
-
including
amongst others Rupert Brown and Donald Taylor. It is perhaps superfluous to add that our past
and present disagreements are and have been as useful as our agreements in enabling
us
to
extend our work
in
new directions.
An
important aspect of ‘social reality’ is that most social systems contain collections of
individuals who differ from each other
in
a variety of ways. Some of these differences can easily
be ascertained to exist by an outside ‘objective’ and uncommitted observer; for example,
differences
in
sex, age, wealth, power, forms of work, forms of leisure, dress, language, etc.
The observer has certain tools which will enable him to structure these differences
in
one way or
another, i.e. to establish his own ‘construction
’
of any particular social ‘reality
’.
This is often
attempted in an ‘outside
’
stance by sociologists, social anthropologists or social historians. The
individuals inside the system have also tools to do this kind of job; the tools used by both the
outsiders and the insiders are not dissimilar. But the
criteria
for accepting the validity of one
construction or another may differ vastly between those who engage in the ‘outside’
construction for their professional (‘scientific
’)
purposes and those inside the system who need
guidelines for their behaviour and thus attempt to construct a coherent system of orientation
in
their social environment.
Social categorization is one of these tools (cf. Tajfel,
1969, 1972b).
But the fact that this tool
exists (i.e. that it is a part of human cognitive equipment) provides
us
with
no
more information
as to whether, when or how it will be used than knowing that a man has bought a do-it-yourself
kit would by itself inform
us
whether, when, how and for what purposes he will use it. We only
know that there are some things he can do with his kit (there may be some we do not know
about
if
we underestimate his ingenuity); and we also know that some constructions are
definitely impossible because of the limitations of this particular box of tricks. For example: an
‘outside
’
observer may notice (and check with other outside observers) that
in
a society he is
looking at some individuals are ‘black’ and some are ‘white
’.
This information, however
‘objective’ it is, would not by itself enable him to conclude that his ‘black’- ‘white’ distinction
is one
on
which the tool kit of social categorizing has been put to use, i.e. that this distinction is
in
any way relevant to the social behaviour inside the system.
As
I wrote above, the aim of a theory of inter-group behaviour is to help
us
to understand
certain selected uniformities of social behaviour. In order to do this, we must know
(i)
something about the ways ‘groups’ are constructed in a particular social system, (ii) what are the
psychological effects of these constructions; and
(iii)
how the constructions and their effects
depend upon, and relate to, forms of social reality. These are the primary aims of the theory of
