Cook, S. W., Experimenting On Social Issues: The Case of School Desegregation, American Psychologist, 1985, 40, 452-460

This paper demonstrates an experimental approach to studying social issues. After exploratory research to identify variables, quasi-experiments are conducted. Then laboratory experiments are used to measure determinants more closely. Then the main factors are evaluated separately in both lab and field experiments. This is demonstrated using school desegregation as the social issue.

The research is about the "effect of personal contact on attitudes and relationships of persons from disliked groups". It grew out of studying the impact of desegregation possibilities after WWII (was impending desegretation a good idea?). Initial data showed successful contact needed to be on an equal basis with initial cooperation toward a joint goal.

Other quasi-studies showed that desegregation in recreation and housing did improve racial relations. Still it was uncertain how much subject bias was present in these unscientific studies.

There are five main criteria for success of the contact hypothesis:
1. Meet as equals
2. Attributes of disliked group that come out must disconfirm the stereotype.
3. Need mutually interdependent relation (e.g, achievement of a goal)
4. Must have enough contact to see disliked group as individuals
5. Social norms of contact situation should favor equality in groups.

Laboratory Study of the Contact Hypothesis
They set up a study to create the above conditions. White subjects worked with black co-workers to run a mythical train line for 20 days (the black co-worker and white co-worker were confederates). They selected the most predujicial pair of white subjects -- one went to the treatment group, one to the control group (who didn't do the experiment but were measured for race viewpoint at the same time as the treatment group).

Most of the black co-worker contact was during lunch. They scripted the confederate conversations to show egalitarian views from the white co-worker and stereotype-breaking views from the black co-worker (that would individualize him.)

Results
There was a significant increase in racial acceptance for the experiment group vs the control group. For some subjects the change was almost complete -- from racial disapproval to racial approval.

Cooperative Intergroup Contact in a Desegregated School Setting
The researchers set up cooperative interdependence by arranging racially mixed learning teams in English Literature in Denver. They changed the exercises from normally individualy based to team based.

Results
They found lower racial dissension among students who were in the learning teams vs others. Whites in learning groups rated Hispanics as well as fellow whites (but still rated black students lower). In 11 of 13 similar studies, cooperative interdependence was shown to improve racial acceptance.

Further tests
They also tested in the laboratory more variables that may determine racial attitudes in a group setting. They set up a management simulation with a white male subject and a white and black co-worker confederates. In one condition one of the confederates made costly errors that caused the team to fail. In this situation there was little disliking difference if the failing confederate was black or white. The second condition was race -- they found little preferential difference for white or black co-workers in this cooperative situation.

Conclusions
Inter-racial contact in a group setting while working on a common goal can dramatically improve racial perceptions. There is also a positive effect for group success.

Unfortunately, desegration wasn't carried out with the above egalitarian points in mind. It hasn't achieved either an improvement in race relations nor in academic achievement.
