The current research investigated how patterns of home and host cultural identification can explain which individuals who have lived abroad achieve the greatest creative and professional success. We hypothesized that individuals who identified with both their home and host cultures (i.e., biculturals) would show enhanced creativity and professional success compared with individuals who identified with only a single culture (i.e., assimilated and separated individuals). Further, we expected that these effects would be driven by biculturals' greater levels of integrative complexity, an information processing capacity that involves considering and combining multiple perspectives. Two studies demonstrated that biculturals exhibited more fluency, flexibility, and novelty on a creative uses task (Study 1) and produced more innovations at work (Study 2) than did assimilated or separated individuals. Study 3 extended these findings to general professional outcomes: Bicultural professionals achieved higher promotion rates and more positive reputations compared with assimilated or separated individuals. Importantly, in all 3 studies, integrative complexity mediated the relationship between home/host identification and performance. Overall, the current results demonstrate who is most likely to achieve professional and creative success following experiences abroad and why.

In 6 studies, we systematically explored for the 1st time the ameliorative effects of multicultural experience on intergroup bias and investigated the role of epistemic unfreezing as the motivational mechanism underlying these effects. We found that multicultural exposure led to a reduction in stereotype endorsement (Studies 1, 4, and 6), symbolic racism (Study 5), and discriminatory hiring decisions (Study 2). We further demonstrated that experimental exposure to multicultural experience caused a reduction in need for cognitive closure (NFCC; Studies 3 and 6) and that the ameliorative effects of multiculturalism experience on intergroup bias were fully mediated by lower levels of NFCC (Studies 4, 5, and 6). The beneficial effects of multiculturalism were found regardless of the targeted stereotype group (African Americans, Ethiopians, homosexuals, and native Israelis), regardless of whether multicultural experience was measured or manipulated, and regardless of the population sampled (Caucasian Americans or native Israelis), demonstrating the robustness of this phenomenon. Overall, these results demonstrate that multicultural experience plays a critical role in increasing social tolerance through its relationship to motivated cognitive processes.

People are being exposed to second cultures in growing numbers, yet the role played by second-culture exposure in shaping sociocognitive skills has received little theoretical attention. The authors address this gap by exploring the relationship between acculturation strategies and integrative complexity. Consistent with the acculturation complexity model, studies of both Asian American college students (Study 1) and Israelis working in the United States (Study 2) show that biculturals are more integratively complex across domains (e.g., culture, work) than either assimilated or separated individuals. Using priming manipulations to clarify the directional flow of causality between acculturation and integrative complexity, the authors also find that greater integrative complexity among biculturals is driven by acculturation pressures (Study 3). Finally, the authors discuss the adaptive implications of multiculturalism.

Growing numbers of people are being exposed to a second culture, yet the process by which individuals absorb a cultural identity and the role played by second-culture exposure in shaping sociocognitive skills have received little theoretical attention. This article begins to fill these knowledge gaps by delineating the factors that affect the adoption of specific acculturation strategies and focusing on the power of secondculture exposure to stimulate integratively complex cognitions that give people the flexibility to shift rapidly from one cultural meaning system to another. We propose a model, influenced by prior work on value pluralism and accountability, which outlines the underlying mechanisms that determine acculturation choice and that produce both individual difference and situational variation in integrative complexity of social functioning. Implications for expatriate performance are discussed.

In three studies, we examined how diversity ideologies can differentially affect creativity. Building on past research establishing that embracing foreign ideas contributes to creativity in problem solving, we predicted that diversity ideologies would have consequences for cultural creativity through their differential impact on how people would make use of foreign knowledge. We found that colorblindness (the ethos of disregarding cultural differences) was associated with lower cultural creativity through reduced inclusion of foreign ideas. Polyculturalism (the ethos of fostering intercultural interaction) was associated with higher cultural creativity through greater inclusion of foreign ideas. Finally, we found that classical multiculturalism (the ethos of preserving separate cultural traditions) had no effects on creative problem solving. Results held across different populations of participants (Americans, Israelis), different measures of creativity (flexibility, novelty), and different ways of probing ideologies (individual differences, experimental priming). These results indicate that diversity ideologies not only affect how people treat foreign people but also how they treat foreign ideas, with implications for their creativity.
