Abstract
Studies show the importance of information sharing in decision making. However, information sharing also affects intrapersonal perceptions and group dynamics. Three experiments demonstrated that out-of-the-loop individuals experienced thwarted needs (e.g., belonging) and decreased trust and liking of group members. Experiment 1 showed these deleterious effects only occurred when information exclusion appeared intentional. Experiment 2 established that constructive motives could mitigate negative effects of intentional information exclusion. Experiment 3 showed that unintentional information exclusion deflated participants only when perceived as preventable. These experiments also provided evidence for a mediating process. Information exclusion, particularly when ill intentioned or preventable, signals poor group standing, leading to deleterious psychological effects.
