Assessing the Effects of Partisan Bias at the Group Level of Analysis: A Hidden Profile Experiment
Although there is some evidence in the political arena that pooling information can overcome individual biases to improve decision-making accuracy, research from the group communication and psychology arenas suggests otherwise. Specifically, research on the hidden profile, a group-level decision-making problem, suggests that groups are decidedly biased when making decisions. This laboratory experiment tested whether or not partisan biases manifes…
From cooperative to motivated information sharing in groups: Moving beyond the hidden profile paradigm
A seminal study conducted by Stasser and Titus () found that groups often make suboptimal decisions on tasks structured as hidden profiles because they tend to discuss and incorporate into their decisions information that is shared (known to all members) at the expense of information that is unshared (known to a single member). In other words, groups are not able to take advantage of the unique knowledge and expertise of their members. Over the p…
Self-Construal Scales Lack Validity
Self-construal is thought to mediate and explain the effects of culture on a wide variety of outcome variables. A meta-analysis of published cross-cultural self-construal research is reported in this article, and the results across studies suggests that the evidence for the predicted cultural differences is weak, inconsistent, or nonexistent. The results of 3 priming experiments (N = 121, N = 99, and N = 361) suggest that (a) priming does not acc…

Mutual enhancement: Toward an understanding of the collective preference for shared information
Groups tend to discuss and repeat information known by all members (shared) more than they do information known by one member (unshared). One factor that may influence this effect is the tendency for members to positively evaluate one another when mentioning shared information. Three experiments demonstrated this mutual enhancement effect. Experiment I showed that mutual enhancement was related to participants' and their partners' exchanging the …
The Reevaluation of Information during Group Discussion
Communication in small groups often yields uniform judgments among members, particularly when members are similar to one another. This investigation empirically tested whether group discussion leads members' evaluations of information to become more uniform, particularly in groups composed of similar members. Group members evaluated the desirability of positions held by three candidates for student body president before and after discussing the c…
