Which outcome shows the darker side of a highly cohesive work group?

1. Cohesiveness raises productivity only when group performance norms are high. 2. Where they are not, cohesiveness can lead to restricted output. 3. It can also produce resistance to change and conflict with other work groups in the organization. 4. Reduced turnover is a benefit of cohesiveness, so more frequent leaving reverses it. 5. Losing contact would mean the group is not cohesive in the first place. 6. Group-based rewards raise cohesiveness rather than being refused by cohesive groups. _Source: OpenStax Introduction to Business (CC BY 4.0), Ch 7 "Designing Organizational Structures", section 7.3 Using Teams to Enhance Motivation and Performance_
