FRAMING AND GROUP DECISION-MAKING - DO COGNITIVE CHANGES PARALLEL PREFERENCE CHANGES

Subjects had their initial frames of reference concerning a decision problem (Asian Disease problem; Tversky & Kahneman, 1981, Science, 211, 453-458) manipulated in order to compose four-person groups containing members with different frames of reference. Three different group compositions (number of members with “gain-oriented” vs “loss-oriented” frames) were used: three gain-oriented and one loss oriented (3-1), two gain-oriented and two loss-oriented (2-2), and one gain-oriented and three loss-oriented (1-3). Results indicated a postgroup discussion choice shift toward the risk alternative in the 2-2 and the 1-3 composition conditions. However, changes in members′ frames of reference were unrelated to preference changes. Group composition also affected group decision processes. Implications for future theory and research in small group decision-making are discussed. © 1993 Academic Press.
