A Bibliographic Survey of the Activities and International Nature of Multiple Criteria Decision Making

One of the fascinating things about multiple criteria decision making (MCDM) is the degree to which the contributions that have built the field have come from all over the world. In this paper the international nature of the authorships of the 1216 refereed journal articles published on MCDM between 1987 and 1992, and the journals in which they have appeared, is examined. Also, an analysis of the 217 books and 31 journal special issues that have been published on MCDM, and 143 conferences that have been held on MCDM since the inception of the field, is similarly conducted. The paper concludes with a conference organizer, author and special issue guest editor index.     

Gender Effects in Couples' Sexual Decision Making and Contraceptive Use

Previous research has demonstrated that men tend to be more influential than women in mixed-sex dyads. The current study was an examination of sex differences in influence among dating couples making two different kinds of sexual decisions. In a laboratory decision-making task, male and female partners wrote their opinions about premarital sex and contraception independently, and then worked together as a couple to write a joint opinion. The results replicated previous findings in that the male partners' responses were more similar to the couples' responses than were the females'. An examination of gender influence in the couples' contraceptive behavior , however, indicated that the female partners were more influential than the males in this arena. Thus the data suggest that while men in general may be more influential than women in couples' decision making, there are specific decision domains in which women have considerable influence. Factors that influence gender effects in sexual decision making are discussed.

The Rank-Order Effect in Group Decision Making

Many studies indicate that group discussion candisproportionately reflect information known by all group members,at the expense of information known to only one group member, andthis is associated with suboptimal group decisions (Stasser &Titus, 1985). The present study examined the impact of threeprocedural factors on information sharing and quality of groupdecision: (a) group decision procedure (an instruction to "rankorder the alternatives" vs "choose the best alternative"), (b)information access during group discussion (reliance on memory vscomplete access), and (c) communication technology (computer vsface to face). Three-person groups worked on an investment decisionthat was structured as a hidden-profile task where criticalinformation was distributed unevenly prior to group discussion. Thedata provided support for a rank-order effect: Groups instructedto rank order the alternatives, compared to groups instructed tochoose the best alternative, were more likely to fully consider allof the alternatives, exchange information about unpopularalternatives, and make the best decision. But these effects onlyoccurred in face-to-face groups. In computer-mediated groups, therewas general information suppression and no effect of group decisionprocedure. Access to information during group discussion increaseddiscussion of both unique and common information, in theface-to-face conditions, but had no effect on group decisionquality. Taken together, the data suggest that procedural aspectsof group discussion may help overcome the impact of prediscussionpreferences on information processes and group decision.     

Children's Selective Use of Peer Informants: Criteria for Making Information-Seeking Decisions

Children from preschool, first-grade, and fourth-grade classrooms (N = 60) were randomly assigned to two different instructional conditions to assess (a) their recognition of the significance of knowledge versus physical (age or gender) criteria for making information-seeking decisions and (b) their reliance on these criteria in actual need-for-information situations. The results suggest that older children are more likely than younger children to recognize the salience of a peer's knowledge for making information-seeking decisions. Depending on the context, however, even young children may be able to view a peer's knowledge of a particular task as a dimension that takes precedence over such competing cues as gender or age. Age differences in children's tendencies to recognize and apply these criteria are also discussed.     

Regret in Decision Making

Decision research has only recently started to take seriously the role of emotions in choices and decisions. Regret is the emotion that has received the most attention. In this article, we sample a number of the initial regret studies from psychology and economics, and trace some of the complexities and contradictions to which they led. We then sketch a new theory, decision justification theory (DJT), which synthesizes several apparently conflicting findings. DJT postulates two core components of decision–related regret, one associated with the (comparative) evaluation of the outcome, the other with the feeling of self–blame for having made a poor choice. We reinterpret several existing studies in DJT terms. We then report some new studies that directly tested (and support) DJT, and propose a number of research issues that follow from this new approach to regret.     

The Effects of Decision Outcome Dispersion Upon Organizational Decision Making

The effects of varying decision outcome dispersion on organizational decision making were investigated under individual and group decision making conditions. Thirty-six female and pg]36 male subjects made decisions for organizational decision scenarios in which outcomes affected primarily the decision maker, people other than the decision maker, or a group of which the decision maker was a member. Subjects rated their levels of perceived risk and confidence in their decisions and made decisions within a simulated context of either a small or a large organization. Results indicated that subjects perceived significantly less risk and more confidence in their decisions when outcomes affected primarily themselves rather than others regardless of whether the decisions were made individually or by a group. Males perceived their decisions as significantly more risky than females. Induced organizational size did not significantly influence decision making.

     

Decision Development in Computer-Assisted Group Decision Making

New computer technologies to aid group communication and decision making are becoming increasingly widespread. This study analyzes how one such technology, a group decision support system (GDSS), affected how group decisions developed over time. The study contrasted decision paths in groups using the GDSS with groups using the same procedural structures incorporated in the GDSS manually and with groups using no procedural structures. A flexible phase mapping method was employed to map group decision paths. The resulting set of seven decision paths varied in both sequence and number of decision phases. An optimal matching procedure was used to compute similarity measures among the 40 paths, and cluster analysis and multidimensional scaling were used to generate an empirical taxonomy of decision paths. Results indicated that the nature of decision paths varied both across the three conditions and within conditions. The decision path types were also related to three outcome variables: consensus change, perceived decision quality, and decision scheme satisfaction. Results indicated that those decision paths that most resembled logical normative sequences had superior outcomes to those that did not.     

Individual Characteristics of Political Leaders and the Use of Analogy in Foreign Policy Decision Making

The linkages between individual characteristics of political leaders and their usage of historical analogy during foreign policy decision-making episodes were examined. The individual characteristics studied were conceptual complexity and policy expertise, while usage of analogy was studied in terms of the sophistication and source of historical comparisons. The great majority of the analogies used by low-complexity individuals were nonsophisticated, whereas high-complexity individuals consistently used more sophisticated analogies. Low-complexity individuals drew analogies solely from their own generational and cultural context, while high-complexity leaders drew their analogies from a wider range of sources. More expert leaders drew from their personal experiences to a marginally greater degree than less expert individuals but, interestingly, both types of individual relied on generally available rather than personally experienced events for their analogies. The value added of the approach is to demonstrate that different types of leaders use history differently during political decision making.     

Beyond the Obvious: Chronic Vividness of Imagery and the Use of Information in Decision Making

The authors investigate two competing hypotheses about how chronic vividness of imagery interacts with the vividness and salience of information in decision making. Results from four studies, covering a variety of decision domains, indicate that chronic imagery vividness rarely amplifies the effects of vivid and salient information. Imagery vividness may, in fact, attenuate the effects of vivid and salient information. This is because, relative to nonvivid imagers, vivid imagers rely less on information that appears obvious and rely more on information that seems less obvious. This tendency is so robust that vividness of imagery may amplify the effects of vivid information only when this information is the only information available in the decision field. The findings seem to reflect vivid imagers' tendency to totally immerse themselves in a decision problem and scrutinize the available information creatively.     

The Role of Decision Making Styles in Explaining Happiness

In pursuit of happiness, individuals often choose activities which may be influenced by their general decision making styles that reflect habitual ways of choosing and making decisions. The present study investigated the associations of such tendencies, namely individuals’ temporal perspectives that included present and future focus, and maximizing, with persons’ orientations to happiness and their relevance for subjective well-being. The obtained results confirmed previous reports indicating the relevance of orientations to happiness for subjective well-being. With respect to the decision making styles, they revealed positive correlations with regard to future focus with orientations to meaning and engagement that were also negatively associated with present focus. In addition, present focus was positively correlated with orientation to pleasure. With respect to maximizing, this decision making style was positively associated with all three orientations. While assessing the relevance of decision making styles for subjective well-being, the regression analyses indicated that higher levels of maximizing directly predicted higher levels of negative affect and lower life satisfaction. Next, mediation and network methodologies revealed significant mediating effects of orientations to meaning and engagement with respect to the relationships between future focus with life satisfaction and positive affect, orientation to meaning with respect to the associations between present focus with life satisfaction and positive affect, and orientation to engagement with respect to the relationships between maximizing with life satisfaction and positive affect. These results extend previous knowledge, indicating the relevance of individuals’ decision making styles for their conceptualizations of happiness, as well as subjective well-being.

Unstable Interaction in Multiple Criteria Decision Problems

In this paper, we present a decision‐aid method with interacting criteria. The fuzzy measures used to aggregate the criteria depend on the considered alternatives. Pairwise comparisons on the importance of criteria and some levels of veto (or favor) degrees, specified by the decision maker, are taken into consideration. For each alternative, we search for the fuzzy measure that makes it the best. The orness degrees of the resulting fuzzy measures are compared and the alternative associated with the minimum orness degree is selected. Copyright © 2014 John Wiley & Sons, Ltd.
