When more people are involved in a task, the task is done faster, more easily, and better...right? Not necessarily! Social loafing is the tendency for people in a group to put less effort into the task when the effort is pooled (when they are all supposed to work on the task) compared to when they are all responsible for their own contributions. By having more people involved in the group task, each person can put in a little less effort, thinking that others will make up for their lack of effort. You may have seen this type of situation with, for example, road crews...sometimes there are 10 on the crew, 3 are working hard, 2 are sort of working, and the other 5 are sitting around talking. Are they all putting in as much effort as they would if each worked alone? Probably not.
