Identify which method is not suitable to reduce social loafing?

Their contribution should not be evaluated on individual basis

The correct answer is Option (3) → Their contribution should not be evaluated on individual basis

Social loafing refers to the tendency of individuals to put in less effort when working in a group compared to when working alone. To reduce social loafing, effective strategies include:

a. Making the efforts of each person identifiable. 

b. Increasing the pressure to work hard (making group members committed to successful task performance). 

c. Increasing the apparent importance or value of a task. 

d. Making people feel that their individual contribution is important. 

e. Strengthening group cohesiveness which increases the motivation for successful group outcome.

However, if individual contributions are not evaluated, people may feel less accountable, which actually encourages social loafing rather than reducing it.
