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… Expand

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 theExpand
The Contingent Wisdom of Dyads: When Discussion Enhances vs. Undermines the Accuracy of Collaborative Judgments
TLDR
The research shows that discussion can be a powerful tool for error reduction, but only when appropriately structured: Decision makers should form independent judgments to consider a wide range of possible answers, and then use discussion to eliminate extreme errors. Expand
Some People Heed Advice Less than Others: Agency (but Not Communion) Predicts Advice Taking
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 complementedExpand
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 groupsExpand
Not All Fairness Is Created Equal: Fairness Perceptions of Group vs. Individual Decision Makers
TLDR
It is shown that the mere presence of a group as a decision-making body serves as a cue that increases the accessibility of negative group-related associations in a perceiver's mind following an unfavorable outcome. Expand
Gender Composition and Group Confidence Judgment: The Perils of All-Male Groups
TLDR
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. Expand
Gender Composition and Group Confidence Judgment: The Perils of All-Male Groups
We explore the joint effects of group decision making and group gender composition on the calibration of confidence judgments. Participants in two laboratory experiments, individually and in groupsExpand
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 complementedExpand
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. AcrossExpand

Are We Wise About the Wisdom of Crowds? The Use of Group Judgments in Belief Revision
TLDR
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. Expand
Judgmental aggregation strategies depend on whether the self is involved
Abstract We report the results of a novel experiment that addresses two unresolved questions in the judgmental forecasting literature. First, how does combining the estimates of others differ fromExpand

TLDR
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. Expand
Effects of judges' forecasting on their later combination of forecasts for the same outcomes
Abstract In a first experiment, we show that judges' ability to combine forecasts that they receive from more knowledgeable advisors is impaired when they have previously made their own forecasts forExpand

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