What is the effect of group cohesiveness on group performance?

The correct answer highlights that group cohesiveness can enhance group performance. When individuals within a group feel a strong bond and shared commitment towards common goals, they are often more motivated to contribute effectively. This sense of unity can lead to improved communication, increased trust, and collaboration, which are essential for tackling complex tasks. When team members support each other and are invested in the group's success, they are more likely to exhibit higher levels of engagement and effort.

Furthermore, cohesive groups tend to have clearer communication channels, which facilitate the sharing of ideas and constructive feedback. This collaborative environment fosters innovation and problem-solving, ultimately leading to better performance outcomes. While it's true that cohesiveness can sometimes lead to groupthink or a lack of critical evaluation, in general, a positive level of cohesiveness tends to correlate with enhanced performance across various types of tasks.
