Interesting research coming out of Tufts University showing that racially diverse groups were consistently better at decision making than homogenous groups. While it has been known for some time that minority members are more likely to express divergent viewpoints in diverse groups, this research shows similar advantages for majority members as well.
This study implies that racially diverse groups may be more thorough and competent than homogeneous ones. “Diversity, at least in a group decision-making context, has some real benefits–and for everyone in the group,” says Sommers, one of the study authors.
Specific finding that is interesting-
Juries that include white and black members are likely to exchange more information about the details of a case than all-white juries, a process that may lead to more detailed deliberations and fairer verdicts, according to a study that examined racial composition and group decision making in a mock jury scenario.
The findings suggest that minority members’ input isn’t the only reason for the wider ranging discussions of diverse groups. White study participants who were part of the diverse juries were more willing to discuss racism and accurately cited more case facts than those in all-white groups, possibly because they were motivated to avoid racial bias, the study authors suggests.
Recently, in several talks I have discussed how tagging and several other types of social formations on the web enable more diverse participation in decision making. This and some other previous research shows that diversity is important, not just for making sure minority voices are included, but simply to have better decision making.
