Final answer:
In group decision-making, the exception among the listed characteristics is that groups make decisions quickly, which is typically not true due to complexities such as groupthink and coordination challenges.
Step-by-step explanation:
All the following are characteristics of group decision-making EXCEPT groups make decisions quickly. Group decision-making processes often involve various complexities and challenges. These include collective action problems, which tend to be less severe in small groups for reasons such as it's harder to free ride, individual behavior is easier to monitor, and there's stronger peer pressure. Symptoms of groupthink, such as a sense of invulnerability, perceived moral superiority, and self-censorship, can lead to the inhibition of dissent and can contribute to less effective decision-making. When it comes to coordination, groups must address how to align their members' diverse preferences and opinions. This alignment can lead to transaction costs associated with time and effort, and conformity costs representing the compromise each individual makes from their ideal decision. It's also noteworthy that larger groups might move more slowly and experience more difficulty in influencing policy due to the need to consider numerous voices and reaching a consensus. Ultimately, solving coordination problems in groups can be approached by delegating decisions to a single authority or through broader group involvement. Both methods have trade-offs regarding transaction and conformity costs. Lastly, collective decision-making often leans towards maintaining the status quo, a bias that must be navigated to reach effective group decisions.
