What can negatively affect decision-making processes in groups?

High levels of stress can significantly impair decision-making processes in groups because stress often leads to heightened emotions, reduced cognitive function, and a sense of urgency that can overshadow rational thought. When group members are stressed, they may struggle to think critically, communicate effectively, and consider the viewpoints of others. This can result in hasty decisions without thorough evaluation of alternatives or potential consequences. In a stressed environment, individuals might also become more defensive or less willing to collaborate, leading to a breakdown in teamwork and undermining the group's ability to reach a consensus.

In contrast, active participation from all members, a shared sense of purpose, and clear communication strategies are typically beneficial elements that foster cooperation, enhance understanding, and promote more effective decision-making within groups. These positive factors encourage engagement and collective problem-solving, which stand in stark contrast to the disruptive impact that stress can have on group dynamics.
