Final answer:
Muzafer Sherif and Carolyn Sherif believed that working together to solve a common problem would reduce prejudice behavior, as demonstrated by their Robbers Cave experiment and further supported by diversity training in modern workplaces.
Step-by-step explanation:
Muzafer Sherif and Carolyn Sherif believed that working together to solve a common problem would reduce prejudice behavior. Their work, including the famous Robbers Cave experiment, demonstrated how prejudicial attitudes could be decreased through the pursuit of superordinate goals, where individuals or groups with opposing viewpoints must collaborate to achieve a shared outcome.
This aligns with subsequent findings that support the theory that contact under specific conditions, such as having equal status, common goals, and cooperation, facilitates reduced prejudices. Diversity training in workplaces also utilizes these principles to improve teamwork and reduce bias among employees from different cultural backgrounds.
