we define ourselves by the groups we belong to , and these identities guide our behavior

adapting the values and identity of the group we belong to

comparing our group to others to boost our self esteem

in group

the group that we belong to and identify with

out group

a group we dont belong to and often compare negatively

minimal group paradigm

is a test that shows people favor their own group even if its random or meaningless

tajfel 1971 study aim

to investigate if simply being part of a group is enough to lead discrimination againts others

tajfel 1971 study sample

64 boys ( 14-15 years old ) from a school in UK they all knew eachother

tajfel 1971 study procedure

boys were randomly assigned to groups based on painting preferences,they were asked to assign points to anonymos members of either their own group or the other group , point system were designed to test in group favoritism vs fairness

boys consistently gave more points to their own group ( in group ) even when groups were meaningless

tajfel 1971 study conclusion

being part of a group is enough to proceed in group bias and discriminatory behavior , supporting social identity theory

tajfel 1971 study strenghts

high internal validity / replicability which leads to reliability ( standarzied procedure )
