This study investigated the effect of group composition by sex on choice shifts in group decision-making. The Choice Dilemmas Questionnaire was administered to 93 undergraduate students divided into same-sex or mixed-sex groups. The results suggest that groups' sex composition can affect group decisions. All-male groups tended to make slightly risky group decisions while all-female groups tended to be slightly cautious in their group decisions. However, a counterbalancing appears to occur in mixed-sex groups where no significant choice shifts appear in either direction.
