Why am i out of the loop? Attributions influence responses to information exclusion

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. © 2010 by the society for personality and social psychology,inc.
