What is an advantage of a group that is not very cohesive?

In groups that are not very cohesive, members are less likely to conform to group norms. If the performance norms are low, this lack of conformity can lead to higher individualproductivity as members are less influenced by the group's low standards and may strive to perform better on their own.
