Bicultural individuals differ in the degree to which their cultural identities are integrated versus conflicting—Bicultural Identity Integration (BII). Studies of judgment find that biculturals with less integrated identities (low BIIs) tend to defy salient cultural norms, whereas those with highly integrated identities (high BIIs) conform. This study examined biculturals' judgment in a group decision-making context, focusing on individuals' reactions to consensus in cultural ingroups. Results showed that low (vs. high) BIIs are more likely to resist the group consensus when it is incorrect, but not when it is correct. These findings suggest that contrarian impulses of low BIIs can be channeled towards facilitating constructive conflict—resisting groupthink that results from cultural homogeneity. Implications for bicultural identity, motives, and organizational behavior are discussed.
