What two factors that inhibit individual action within a group setting?

Two factors that inhibit individual action within a group setting are social loafing and groupthink. Social loafing occurs when individuals put in less effort when working in a group, believing that others will carry the workload. Groupthink, on the other hand, leads to a deterioration of mental efficiency and reality testing, as group members prioritize consensus over independent critical thinking, often suppressing dissenting opinions. Both factors can hinder effective decision-making and reduce overall group productivity.
