Final answer:
Diversity among team members does not undermine cohesion and is generally false. Diverse teams can face communication challenges, but also bring varied skills and improved performance. Option B is correct.
Step-by-step explanation:
The statement 'Diversity among team members tends to undermine cohesion' is generally considered false. While it is true that diversity can introduce communication and interpersonal-relationship problems, it also brings a varied skill set that can enhance team performance and interactions.
The team halo effect suggests that teams are often credited for their successes, while failures are attributed to individuals. Gender diversity, as shown in the research by Hoogendoorn, Oosterbeek, & van Praag, can actually improve team performance, as gender-balanced teams reported better sales and profits.
It's also important to note that homogeneity in a team can lead to conformity effects, poor decision-making, and a lack of innovative solutions. Providing diversity training can help bridge cultural differences and improve teamwork.
Pettigrew and Tropp found that contact between diverse groups, under the right conditions, can reduce or eliminate prejudice. Similarly, a 'cohort' is a diverse group that can include variations in age, weight, gender, and health status, indicating the value of diversity in groups.
