Final answer:
Groups making decisions can draw upon diverse perspectives, contributing to more informed outcomes because group members often have the knowledge and expertise relevant to the decision at hand. However, issues like groupthink and group polarization can affect group decisions, though strategies exist to mitigate their effects.
Step-by-step explanation:
One of the best reasons for allowing groups to make decisions is c) The people who are affected by the decision are often the best qualified to make decisions that affect them. This approach is often seen in collective decision-making where group members bring diverse perspectives and can contribute to a more robust and informed decision. In comparison to individual decision-making, a group can draw upon the collective knowledge and expertise of its members, leading to potentially better outcomes.
It is important to note that group decisions can be subject to phenomena such as groupthink and group polarization, which can skew the decision away from the best possible outcome. However, effective strategies to combat these issues, like seeking outside opinions and voting in private, can improve group decision-making. Additionally, in small groups, collective action problems are less severe due to the ability to monitor individual behavior more effectively, reducing the incidence of free riding and enforcing stronger peer pressure, which in turn can improve the quality and accountability of the decisions made.
