Which of the following is a fundamental group norm that emphasizes collective integrity?

Confidentiality is considered a fundamental group norm that emphasizes collective integrity because it involves the protection of sensitive information shared within the group. When group members adhere to confidentiality, they establish trust and create an environment where individuals feel safe to express their thoughts, share insights, and discuss issues openly. This level of trust is essential for fostering a cohesive group dynamic, where members are confident that their contributions will be respected and protected.

In contrast, while punctuality, providing feedback, and managing assignments are important for group functioning, they do not directly address the aspect of integrity in the same way that confidentiality does. Punctuality pertains more to respect for others' time, providing feedback focuses on communication among members, and assignments deal with task distribution and accountability. None of these elements capture the essence of collective integrity as confidentiality does, making confidentiality a cornerstone of an ethical and trustworthy group environment.
