Social loafing occurs when one or more group members rely on the efforts of other group members and fail to contribute their own time, effort, thoughts, or other resources to a group. This may create a real brag on the group's efforts and achievements. Some scholars argue that, from the individual's stand-point, social lofing, or free riding, is rational behavior in response to an experience of inequity or when individual efforts are hard to observe. However, it shortchanges the group, which loses potentially valuable resources possessed by individual members.
