Media images of walls being erected or dismantled symbolize the global dilemma at the heart of the approach toward diversity during economically challenging times. Will communities, organizations, and nations become more isolated, exclusionary, and protective of scarce resources? Or will they embrace diversity for humanistic reasons and its potential to drive economic growth? This paper first critically examines the paradox of diversity and deems it false because it omits the important role of inclusion climate. It then presents a systematic review of the research. Findings indicate that people are more likely to blame ‘the other’ for their economic hardships, and as a result are more likely to express racism, prejudice, and xenophobia, giving rise to intergroup conflicts and strife. Yet research also links diversity with innovation and its potential to uplift and energize economies, a quality that is particularly important during times of economic hardship. Finally, the paper presents a theory‐based conceptual model, highlighting the central role of inclusion, and proposes directions for future research.
