Problems and Solutions Social facilitation, social loafing, and deindividuation can all affect individuals whether they are working in real groups or are merely part of a collective or crowd. In this section, we examine processes that are specific to groups, where interaction among members is more direct and meaningful. We focus on how well groups perform, and, in doing so, we address a fundamental question: Aren’t two (or more) heads better than one? Although eight people typically can outproduce a lone individual, do eight people working together in a group typically outperform the sum of eight people working individually? You may be surprised to learn how often and in what ways groups perform worse than their potential would suggest. We also discuss when and how groups are more likely to perform well.
