Final answer:
GRIT aims to reduce conflict through the establishment of superordinate goals, requiring cooperative efforts to achieve shared objectives, as shown in studies like the Robbers Cave experiment.
Step-by-step explanation:
GRIT is a strategy that attempts to reduce conflict through various nonviolent means. One effective approach within this strategy is the establishment of superordinate goals, which are overarching objectives shared by conflicting groups that can only be achieved through cooperative efforts. This concept is supported by research such as the Robbers Cave experiment which showed a decrease in prejudice when opposing groups worked together towards a common goal. Similarly, practices such as the jigsaw classroom technique demonstrate that cooperative working environments encourage teamwork and reduce potential for prejudice by focusing on a shared outcome.
