Final answer:
To reduce prejudice, research shows that intergroup contact through cooperative interaction, focusing on superordinate goals, and practices like the jigsaw classroom technique can be beneficial. Mutual interdependence and equal status must also be present. Additionally, institutional support and policies fostering an accepting multicultural environment are necessary.
Step-by-step explanation:
To reduce prejudice, a negative attitude based on group membership, several strategies have been proposed and supported by research. Intergroup contact, involving cooperative interaction between groups, is one effective method. The Robbers Cave experiment is a prime example whereby two opposing groups in a camp worked collaboratively towards a superordinate goal and, as a result, their prejudicial attitudes decreased. This illustrates the importance of collaborating to achieve a common goal in reducing prejudice.
Another strategy is the implementation of the jigsaw classroom technique, which mixes students of diverse backgrounds. By assigning interdependent parts of a task and facilitating interaction among different groups working on a shared goal, this approach reduces the potential for prejudice. Such sustained contact encourages empathy and understanding.
Mutual interdependence and equality (equal-status contact) are also critical conditions. When diversity training in workplaces provides a platform for equal standing and common goals among internationally diverse teams, it aligns with the findings of Pettigrew and Tropp's meta-analysis: contact under such conditions reduces prejudice.
Emphasizing mutual respect and pluralism, where no distinction is made between minority and majority groups, creates a multicultural environment of acceptance. Reducing prejudice not only involves changes at the individual level but requires institutional support and the implementation of policies that foster equality and collaboration.
