Effects of Consensus Information and Task Demonstrability on Preference-Consistent Information Evaluation and Decision Quality in Group Decision Making

Groups often fail to solve hidden profiles even when all information is exchanged. This is partly due to biased evaluation of information. We examined the effects of consensus information and task demonstrability on preference-consistent information evaluation and decision quality. The results showed that the evaluation of unshared but not shared information was moderated by consensus information and task demonstrability. For unshared information, majority members exhibited a higher evaluation bias favoring preference-consistent information than minority members. Task demonstrability reduced the evaluation bias only when group members received no information about the other members' preferences. Finally, majority members were less likely to solve the hidden profile than minority members, and this was partially mediated by the evaluation bias favoring preference-consistent unshared information.     

Exceptions to the Rule: The Effects of Remorse,Status, and Gender on Decision Making1

One of several general rules suggested by past work is that it is advantageous to exhibit remorse when one has committed a transgression. A pair of experiments searched for the boundary conditions of this rule. In Experiment 1, mock jurors rated a remorseful defendant as more guilty when the law was fair than when the law was unfair. In contrast, an unremorseful defendant was viewed as equally guilty under both fairness levels. Study 2 conceptually replicated this result, and revealed a 3‐way interaction among remorse, status, and gender. It is argued that these findings illustrate the importance of violation of expectations on evaluation and judgment, inside the courtroom and elsewhere.     

The Political Manipulation of Group Composition: Engineering the Decision Context

Group decisions are not made solely by evaluating the merits of the contending positions. Instead, actors may engage in manipulation to increase the fortunes of their policy preference. Actors may manipulate information, group procedures, or group composition. Using a model of group socialization, this paper argues that a manipulator may seek to alter the group composition as to access and/or status. In doing so, the manipulator seeks to create a more favorable decision environment. This political perspective maintains that the dynamic nature of group composition provides an opportunity for a manipulator to engineer the decision context, potentially affecting the group's decisional output. Strategies and tactics of composition manipulation are presented and then utilized to analyze the American decision process during the Iranian revolution.     

Information Suppression and Status Persistence in Group Decision Making The Effects of Communication Media

This experiment investigated the conditions under which a member with information critical for making the best group decision will positively influence the group's final choice. The impact of two factors on group decision quality, information exchange, and perceptions of influence was examined: (a) status differences among members (equal-status vs. mixed-status groups) and (b) communication media (face-to-face vs. computer-mediated communication). Three-person groups were composed such that the critical information required to make the best decision was given only to the low-status member in the mixed-status groups and randomly assigned to one member in the equal-status groups. The results indicated that the mixed-status groups made poorer decisions and made fewer references to critical information than equal-status groups, regardless of the communication medium. Computer-mediated communication suppressed information exchange and the perceived influence of group members, suggesting that the relation between status and communication media is more complex than proposed in past research.     

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.     

Framing Effects and Choice Shifts in Group Decision Making

An experiment was conducted to examine the effects of framing on group decision-making. Decisions involving risk were posed in terms of either gains or losses to individual subjects. Subsequently, subjects were divided into groups and the decisions were presented again in either the same frame or the opposite frame. As hypothesized, when the same frame was presented to subjects both individually and in groups, individual-level framing effects became larger in groups; when the opposite frame was presented to groups, initial framing effects were reduced. However, these results were observed on only two of the four decision cases. On the other two cases, significant choice shifts occurred independently of the framing manipulations. Implications of these results for decision making groups in applied settings are discussed.

Influences of Destructive Personality Information on Decision Making1

This study examined the effects of information about a landlord's personality on juror judgments for a landlord-tenant civil trial. The personality information manipulated was specifically relevant to destructive acts. Alternative versions of witness testimony were used to describe a landlord either high or low on need for power. treating people as objects, and negative life themes. This information strongly influenced aspects of the schema for this case constructed by the individual mock jurors. Destructive personality information caused dislike of the landlord and lowered the credibility of his story. If the landlord treated people as objects, the credibility of the tenant's story and positive evaluations of the tenant increased. Juror judgments about relative fault were strongly shifted by destructive personality information. An empirical model for juror decisions indicated a dynamic interplay of story components and fault judgments.     

The Effects of Differing Knowledge Transfer Strategies on Group Decision Making and Performance

Encouraging reflection on one's existing knowledge in a group setting increases shared understanding, makes information available for problem solving, and makes it easier for members to show and to be shown the merit of others' preferences. However, it is also possible that attempting to constrain the process by which problem solvers manage this reflection process may prevent them from effectively tailoring their approach to different problems. The current research focuses on how the nature of different knowledge transfer strategies impacts problem solving processes and outcomes by examining manipulations of, or constraints to, problem solvers' approach to knowledge transfer. Participants were directed to generate associated knowledge in preparation for answering a series of estimation items, either in a group or individually. We found that groups using a shared reflection process (as opposed to reflecting at an individual member level) were able to give more weight to the inputs of their more expert members and that groups outperformed individuals. We discuss the process of promoting knowledge transfer in a group context relative to an individual context and relate this to the concept of task demonstrability.

Groups and Solos in Context: The Effects of Accountability on Team Negotiation

This study examines whether and how accountability to constituents affects the cognitions, performance, and outcomes of team and solo negotiators. Previous findings for solos were replicated here: solo negotiators respond competitively when they are accountable to constituents. For teams, however, accountability pressures were distributed across the members resulting in each team member experiencing little responsibility for outcomes. As a consequence, teams did not respond to accountability pressures by behaving contentiously as solos did. Analysis of negotiators' perceptions of advantage reveals that solos who negotiate under conditions of high accountability consider themselves to be at a disadvantage in the negotiation even before the negotiation begins. These perceptions may underlie the accountability/competitive relation that characterizes solo negotiation. Implications for negotiation research as well as the study of groups in organizations are discussed.     

Social Context Effects in the Display of Emotion: Accountability in a Simulated Organization1

Emotional labor involves employees' displays of appropriate emotions done to comply with emotional display rules created to attain organizational goals. This study examined whether display rules operationalized as process accountability (being held accountable for the quality of emotional displays during social interactions) and as outcome accountability (being held responsible for producing desired outcomes in others) would affect participants' emotional labor. In a simulated job interview, process accountability increased emotional labor; this occurred only in the absence of outcome accountability. The findings imply that display rules that encourage attention to sustaining quality interactions are likely to be more successful in achieving organizational goals than are rules that focus directly on producing predetermined outcomes.     

Computer-Mediated Communication and Group Decision Making: A Meta-Analysis

A meta-analysis of research comparing decision making in face-to-face versus computer-mediated communication groups was conducted. Results suggest that computer-mediated communication leads to decreases in group effectiveness, increases in time required to complete tasks and decreases in member satisfaction compared to face-to-face groups. All of the moderators tested (anonymity in the group process, limited versus unlimited time to reach decisions, group size, and task type) were significant for at least one of the dependent variables. The article concludes with cautions about the unbridled rush by organizations to adopt computer-mediated communication as a medium for group decision making and implications of the present findings for theory and research on computer-mediated communication and group decision making.     

Self-Evaluation Bias of Social Comparisons in Ethical Decision Making: The Impact of Accountability

The purpose of this paper is to examine how accountability and judgment biases that occur in social comparisons may be related to ethical decision making. Using Jones' (1991 ) model as the theoretical framework to investigate this phenomenon, we found that self-enhancing individuals (i.e., those who thought they were more ethical in comparison to their peers) demonstrated higher responsiveness to increases in accountability than did self-effacing individuals (i.e., those who thought they were less ethical in comparison to their peers). We discuss these findings and outline the implications for future ethics research. Further, we provide practical guidance to those who administer ethics compliance programs on effective ways of facilitating ethical behavior in organizations.     

Multiattribute Decision Making in Context: A Dynamic Neural Network Methodology

A theoretical structure for multiattribute decision making is presented, based on a dynamical system for interactions in a neural network incorporating affective and rational variables. This enables modeling of problems that elude two prevailing economic decision theories: subjective expected utility theory and prospect theory. The network is unlike some that fit economic data by choosing optimal weights or coefficients within a predetermined mathematical framework. Rather, the framework itself is based on principles used elsewhere to model many other cognitive and behavioral data, in a manner approximating how humans perform behavioral functions. Different, interconnected modules within the network encode (a) attributes of objects among which choices are made, (b) object categories, (c) and goals of the decision maker. An example is utilized to simulate the actual consumer choice between old and new versions of Coca-Cola. Potential applications are also discussed to market decisions involving negotiations between participants, such as international petroleum traders.

Accountability Forces in Performance Appraisal: Effects of Self-Appraisal Information, Normative Information, and Task Performance

This study investigated the effects of self-appraisal information, normative information, and task performance on performance appraisal ratings. Participants rated a fictitious subordinate's performance on a clerical task (which was either very good or moderately poor) subsequent to receiving self-assessment information (high or low) and normative information (present or absent). Self-appraisals affected performance ratings for poor performers but not for good performers, suggesting that judges are more motivated to please ratees than they are merely to adopt the subordinate's view of their own performance. Furthermore, objective normative information had greater influence than self-appraisals on performance ratings, suggesting that information source credibility has more influence than felt accountability on performance appraisals. Implications of the findings for organizations were discussed.
