- Group decision-making (also known as collaborative decision-making or collective decision-making) is a situation faced when individuals collectively make a choice from the alternatives before them. The decision is then no longer attributable to any single individual who is a member of the group. This is because all the individuals and social group processes such as social influence contribute to the outcome. The decisions made by groups are often different from those made by individuals. In workplace settings, collaborative decision-making is one of the most successful models to generate buy-in from other stakeholders, build consensus, and encourage creativity. According to the idea of synergy, decisions made collectively also tend to be more effective than decisions made by a single individual. In this vein, certain collaborative arrangements have the potential to generate better net performance outcomes than individuals acting on their own. Under normal everyday conditions, collaborative or group decision-making would often be preferred and would generate more benefits than individual decision-making when there is the time for proper deliberation, discussion, and dialogue. This can be achieved through the use of committee, teams, groups, partnerships, or other collaborative social processes. However, in some cases, there can also be drawbacks to this method. In extreme emergencies or crisis situations, other forms of decision-making might be preferable as emergency actions may need to be taken more quickly with less time for deliberation. On the other hand, additional considerations must also be taken into account when evaluating the appropriateness of a decision-making framework. For example, the possibility of group polarization also can occur at times, leading some groups to make more extreme decisions than those of its individual members, in the direction of the individual inclinations. There are also other examples where the decisions made by a group are flawed, such as the Bay of Pigs invasion, the incident on which the groupthink model of group decision-making is based. Factors that impact other social group behaviours also affect group decisions. For example, groups high in cohesion, in combination with other antecedent conditions (e.g. ideological homogeneity and insulation from dissenting opinions) have been noted to have a negative effect on group decision-making and hence on group effectiveness. Moreover, when individuals make decisions as part of a group, there is a tendency to exhibit a bias towards discussing shared information (i.e. shared information bias), as opposed to unshared information.

- La prise de décision collective (en anglais, collaborative decision making ou CDM) est une situation où des individus sont rassemblés en un groupe pour résoudre des problèmes. Selon l'idée de synergie, les décisions prises collectivement ont tendance à être plus efficaces que les décisions prises individuellement. Cependant, il existe des situations dans lesquelles les décisions prises en groupe aboutissent à un mauvais jugement. En psychologie sociale, la prise de décision collective peut être définie comme « une convergence d'interactions cognitives et visuelles, planifiées ou opportunistes, où des personnes acceptent de se rassembler pour un objectif commun, dans une période de temps définie, […] dans le but de prendre des décisions ». La prise de décision collective est un domaine d'étude vaste auquel plusieurs disciplines s'intéressent, comme les sciences sociales, les sciences politiques, l'informatique ; on s'y intéresse également en marketing et en management, chacun de ces champs d'étude ayant son point de vue sur la recherche de la prise de décision collective. Du point de vue de la psychologie sociale plus spécifiquement, des applications et des conséquences théoriques sont nombreux et variés dans différents domaines comme la gestion d'équipe, les situations de jurys, la politique, etc. Il existe différents types de décisions collectives chacune ayant des modalités et des processus psychologiques bien spécifiques à la prise de décision collective, tels que la , la pensée de groupe et le Common Knowledge Effect.

- 集體決策是指一個團體从备选方案中做出选择。这时的决策並非由群体中的任何一个人决定。此時所有的人都会对结果产生影响。群体做出的决定往往与个人做出的决定不同。集體決策的結果可以让其他利益相关者接受，彼此之間達成共识。根据協同效應的理念，集体做出的决定也往往比单个人做出的决定更佳。因為集體決策時，大家可以就一些事情進行共同审议、讨论和对话。 但是在某些情况下，这种方法也可能存在缺陷。在极端紧急情况或危机情况下，其他形式的决策可能更可取，因为紧急狀況下可能需要人們更快地下決定。 另一方面，在進行集體決策时，还必须考虑其他因素。例如群体极化這一情況。 (zh)
