Group decision-making is a research area that focuses on how individuals in a group make decisions collectively. It explores the dynamics of group interactions, the influence of different group members on the decision-making process, and the methods that can be used to effectively reach consensus or make decisions as a group. Researchers in this field study topics such as leadership dynamics, communication strategies, conflict resolution, decision-making biases, and the impact of social norms on group decisions. Overall, the goal of group decision-making research is to understand how groups can make better decisions together and improve overall decision-making processes.
