Prior investigators have asserted that certain group characteristics cause group members to disregard outside information and that this behavior leads to diminished performance. We demonstrate that the very process of making a judgment collaboratively rather than individually also contributes to such myopic underweighting of external viewpoints. Dyad members exposed to numerical judgments made by peers gave significantly less weight to those judgments than did individuals working alone. This…

Why dyads heed advice less than individuals do

Following up on a recent debate, we examined advice taking in dyads compared to individuals in a set of three studies (total N = 303 dyads and 194 individuals). Our first aim was to test the

The Contingent Wisdom of Dyads: When Discussion Enhances vs. Undermines the Accuracy of Collaborative Judgments

We evaluate the effect of discussion on the accuracy of collaborative judgments. In contrast to prior research, we show that discussion can either aid or impede accuracy relative to the averaging of

Advice taking by groups: The effects of consensus seeking and member opinion differences

Individuals often underutilize the advice they receive from others, a phenomenon known as egocentric advice discounting. Recent research suggests that this tendency may be even stronger in groups

Gender Composition and Group Confidence Judgment: The Perils of All-Male Groups

It is found that compared to a statistical aggregation of individual confidence intervals, group discussions have a neutral or positive effect on the quality of confidence judgments for groups with at least one female group member; in contrast, group discussion actually harms confidence calibration for all-male groups.

SOME PEOPLE HEED ADVICE LESS THAN OTHERS 2 Some People Heed Advice Less Than Others : Agency ( but not Communion ) Predicts Advice Taking Advice is an important ingredient in human interaction

Across three studies (total N = 793), we investigated the link between two fundamental dimensions of personality, agency and communion, and advice taking in quantity estimation tasks. We complemented

Organizational Behavior and Human Decision Processes

It is generally believed that self-disclosure has positive effects, particularly for relationships; however, we predict and find negative effects in the context of task-oriented relationships. Across

The anchoring-bias in groups

The development of adaptive conformity in young children: effects of uncertainty and consensus.

The mechanism for incorporating social information into decision-making is initially very blunt, but across the course of early childhood it converges on the adaptive learning mechanisms observed in adults and predicted by cultural evolutionary theory.

A meta-analysis of the weight of advice in decision-making

The degree to which people take advice, and the factors that influence advice-taking, are of broad interest to laypersons, professionals, and policy-makers. This meta-analysis on 346 effect sizes

21 Human culture relies on extensive use of social transmission, which must be integrated with 22 independently acquired (i.e., asocial) information for effective decision-making. Formal 23



Are We Wise About the Wisdom of Crowds? The Use of Group Judgments in Belief Revision

Four studies examining intuitions about group wisdom and the informational influence of groups find that when provided advice, participants relied more on groups than individuals to update their beliefs, but were only modestly sensitive to group size.

Strategies for revising judgment: how (and how well) people use others' opinions.

The authors developed the probability, accuracy, redundancy (PAR) model and found that averaging was the more effective strategy across a wide range of commonly encountered environments and that despite this finding, people tend to favor the choosing strategy.

The Effects of Group Longevity on Project Communication and Performance.

In his research on engineering project teams, for example, Allen (1977) carefully demonstrated that only 11 percent of the sources of new ideas and information could be attributed to written media;

Trust, Confidence, and Expertise in a Judge-Advisor System.

Judges had higher and more variable ratings of trust in their partner than did Advisors, suggesting that Judges were more motivated to evaluate trust and high confidence by Advisors had a positive impact on Judges' ratings of Trust and tendency to follow their advice.

Biased Assimilation and Attitude Polarization: The Effects of Prior Theories on Subsequently Considered Evidence

People who hold strong opinions on complex social issues are likely to examine relevant empirical evidence in a biased manner. They are apt to accept "confirming" evidence at face value while

Demography and Design: Predictors of New Product Team Performance

The increasing reliance on teams in organizations raises the question of how these teams should be formed. Should they be formed completely of engineers or should they include a range of specialists?
