Social loafing. A participant puts in less effort as the group size increases.
• Group members feel less responsible for the overall task being performed and therefore exert less effort.
• Motivation of members decreases because they realize that their contributions will not be evaluated on an individual basis.
• The performance of the group is not to be compared with other groups.
• There is improper coordination (or no coordination) among members.
• Belonging to the same group is not important for members. It is only an aggregate of individuals.
