Contingent Weighting in Self-Other Decision Making.

Three studies are presented that examine the decision-making processes that lead advisors to have preferences distinct from personal decision makers (Kray & Gonzalez, 1999). Advising and personal decision making were hypothesized to invoke different interpersonal frames, which lead to different weighting of decision attributes. Alternatively, advisors might simply exert less effort in decision making for others than do personal decision makers. In Study 1, the contingent weighting of attributes was examined in two decision-making tasks (choice vs. matching). Advisors were more likely to choose in a manner consistent with "what most people would prefer" than personal decision makers, but no differences in preferences were observed in the matching task. Advisors subsequently reported experiencing less regret and blame and more strongly preferred the chosen alternative than did personal decision makers. In Study 2, advisors considered more decision attributes to be important in the abstract compared to personal decision makers, and the choice pattern of Study 1 was replicated. In Study 3, advisors and personal decision makers generated more considerations when making a decision compared to individuals making decisions in the abstract. Finally, the preferences of personal decision makers were more consistent with their reported attribute importance judgments than were those of advisors. In total, the results suggest advisors incorrectly infer others' preferences, rather than suffer from a deficit of motivation, when giving advice. Copyright 2000 Academic Press.
