• This study was conducted to examine (a) the effect of uncertainty of information on one's own ability (IS) and of the partner's ability (IGM) on task choice and choice shift, and (b) the relationship of importance of each information to task choice and choice shift. Fifty-four undergraduates (26 males, 28 females) were first given IS (certain or uncertain) followed by the initial choice and then IGM (certain or uncertain) followed by the second choice. When IS and IGM were both certain or uncertain, no choice sift occurred, and importance of each information was seen nearly equal. Choice shift occurred when one information was certain and the other uncertain, its direction being a function of which information was certain. Importance of each information also differed between the combinations of uncertainty. It was suggested that uncertainty of cue information was a determinant of decision making and that the way to utilize it in decision making differed depending on its uncertainty.
