Research on hidden profiles (G. Stasser, 1988) reveals that groups often have trouble utilizing unshared information and making the optimal decision in decision-making contexts. However, a directive group leader advocating the best decision can help a group overcome this problem (M. G. Cruz, D. D. Henningsen, & B. A. Smith, 1999). The current study examines how a leader's access to information affects the quality of group decisions and information sharing. In addition, how leader selection processes affect leader influence is considered. Overall, evidence is found indicating a leader's access to information and leader selection processes influence group discussions and decision quality.
