Biculturals outperformed all other acculturation types on creative tasks.

Evidence

We found that “biculturals,” those who highly identified with both their home and host countries, came up with the most creative uses for a brick compared to those who identified with only their host country (termed assimilated individuals; see Berry, 1997), those who identified with only their home country (separated individuals), or those who identified with neither country (marginal individuals; Tadmor et al., 2010, study 1). This creative advantage was found not only when coders rated the overall creativity of uses but also when they rated the number of uses participants generated (a measure of creative fluency) and the number of different categories for such uses (a measure of creative flexibility), such as weapons or tools (Tadmor, Galinsky, & Maddux, 2010). — Roderick M.
