social identity theory
Social Identity Theory (SIT), developed by Henri Tajfel and John Turner, explains how individuals
derive a sense of identity and self-esteem based on their membership in social groups.
According to SIT, people categorize themselves and others into in-groups (groups they identify
with) and out-groups (groups they do not identify with). This categorization often leads to in-
group favoritism and out-group discrimination, as individuals strive to enhance their self-image
by elevating the status of their in-group relative to out-groups.
Tajfel et al. (1971) conducted a series of experiments, known as the minimal group paradigm,
to investigate the minimal conditions required for discrimination to occur between groups. In
these experiments, participants were randomly assigned to groups based on arbitrary criteria,
such as their preference for certain paintings or even a coin toss. The participants were then
asked to distribute small amounts of money to other participants, knowing only the group to
which each participant belonged.
Despite the arbitrary and meaningless basis for group assignment, Tajfel found that participants
consistently favored members of their own group (in-group) over members of the other group
(out-group). They allocated more money to in-group members and were willing to maximize
the difference in rewards between the groups, even if it meant their own group would receive
less overall, as long as the out-group received even less.
This behavior demonstrated that mere categorization into groups, even without any meaningful
or real-life significance, was enough to trigger in-group favoritism and out-group discrimination.
This supports the core idea of Social Identity Theory: that individuals derive part of their
identity and self-esteem from their group memberships and are motivated to perceive their in-
group positively, often at the expense of out-groups.
Tajfel et al. (1971) provides empirical evidence for Social Identity Theory by showing how
minimal group distinctions can lead to discriminatory behavior. The study highlights how social
identity, even when based on trivial or arbitrary criteria, can significantly influence behavior,
leading to in-group favoritism and out-group bias. This supports the idea that social identity and
the need for positive self-esteem are powerful drivers of human behavior, leading to the
formation of group-based prejudices and conflicts.
