Free-riding and Social loafing. Group members do not remember as much as they have the capacity to remember, as group members engage in free-riding and social loafing. When group members realize - be it implicitly or explicitly - that others will aid in the recall of information, they will put less effort into processing and storing the information. In some situations, these inadequacies in collective memory may be so great that groups are unable to recall previously-made decisions without the aid of a written record (group minutes).
