Decline in group cohesiveness appears when the members of the group are not strongly attached to each other and there is no cooperation between them. Several factors could decrease group cohesion. Some of them are:
- the group is big
-members have conflicting opinion about group goals,
- the group is heterogeneous (with members from different age groups, job responsibilities, education or status)
- there is intra-group competition, in which individual goals are at the cost of group goals.
