Social loafing is more likely to occur in which of the following situation?

Belonging to the same group is not important for members.

Social loafing occur due to following:

1. Group members feel less responsible for the overall task being performed and therefore exert less effort. 

2. Motivation of members decreases because they realise that their contributions will not be evaluated on individual basis. 

3. The performance of the group is not to be compared with other groups.

4. There is an improper coordination (or no coordination) among members.

5. Belonging to the same group is not important for members. It is only an aggregate of individuals.
