tried to reduce intergroup conflict.
For example:
• The researchers introduced superordinate goals which were tasks
that would require the efforts of both groups (1). An example is
when the Rattlers and the Eagles worked together to restore the
water supply which enabled both groups to have water (1).
• The researchers created tasks that needed all boys to cooperate to

the Rattlers and the Eagles pooled their money so they could afford
