Which of the following best describes social loafing?

Social loafing refers to the phenomenon where individuals exert less effort when working in a group compared to when they are working independently. This behavior typically arises from a diffusion of responsibility, where individuals feel less accountable for the outcome because they are part of a group. As a result, some members may contribute less effort, assuming that others will compensate for their reduced participation. This concept is significant in understanding group dynamics, team performance, and the importance of individual accountability within group settings.

In this context, the option highlighting members exerting less effort in a group task accurately captures the essence of social loafing, distinguishing it from other group behaviors like increased competition or collective achievement.
