Expanding diversity in the workplace is often seen as a good way to inject fresh ideas into an otherwise stagnant environment, and incorporating new perspectives can help members tackle problems from a number of different angles. But few have looked into exactly why or how this is so. New research finds that socially different group members do more than simply introduce new viewpoints or approaches. In the study, diverse groups outperformed more homogeneous groups not because of an influx of new ideas, but because diversity triggered more careful information processing that is absent in homogeneous groups.
The mere presence of diversity in a group creates awkwardness, and the need to diffuse this tension leads to better group problem solving, says Katherine Phillips, an associate professor of management and organizations at the Kellogg School of Management. She and her coauthors, Katie A. Liljenquist, an assistant professor at Brigham Young University, and Margaret A. Neale, a professor at Stanford University, demonstrate that while homogenous groups feel more confident in their performance and group interactions, it is the diverse groups that are more successful in completing their tasks.
Stifling Situations
Though people often feel more comfortable with others like themselves, homogeneity can hamper the exchange of different ideas and stifle the intellectual workout that stems from disagreements. Generally speaking, people would prefer to spend time with others who agree with them rather than disagree with them, Phillips explains. But this unbridled affirmation does not always produce the best results. When you think about diversity, it often comes with more cognitive processing and more exchange of information and more perceptions of conflict, Phillips says. In diverse settings, people tend to view conversations as a potential source of conflict that can breed negative emotions, and it is these emotions that can blind people to diversitys upsides: new ideas can emerge, individuals can learn from one another, and they may discover the solution to a problem in the process. Its kind of surprising how difficult it is for people to actually see the benefit of the conversations they are having in a diverse setting, observes Phillips.
