Abstract
Individual and group behavior is studied in three different gambling situations, each involving six choices among bets of which only one is played for money. Actual group decisions following discussion are compared with predictions of a majority-rule, decision-making model. Group choices are significantly more risky than the mean of the initial individual preferences when the potential loss is small, but no difference or slight conservative shifts are observed when the potential loss is relatively great. The majority-rule, decision-making model tested in this study proves fairly satisfactory. It appears, however, that actual group decisions are generally more risky than predicted by this model. It is suggested that changes in risk level following discussion can best be explained in terms of an interaction between majority influence and the social values associated with risky and conservative behavior.
