Decoding the Dynamics of Cultural Change: A Cultural Evolution Approach to the Psychology of Acculturation

PUBLIC ABSTRACT

Acculturation describes the cultural and psychological changes resulting from intercultural contact. Here, we use concepts from "cultural evolution" to better understand the processes of acculturation. Cultural evolution researchers view cultural change as an evolutionary process, allowing them to borrow tools and methods from biology. Cultural evolutionary mechanisms such as conformity (copying the numerical majority), anti-conformity (copying the numerical minority), prestige bias (copying famous individuals), payoff bias (copying successful people), and vertical cultural transmission (copying your parents) can cause people to adopt elements from other cultures and/or conserve their cultural heritage. We explore how these transmission mechanisms might create distinct acculturation strategies, shaping cultural change and diversity over the long-term. This theoretical integration can pave the way for a more sophisticated understanding of the pervasive cultural shifts occurring in many ethnically diverse societies, notably by identifying conditions that empower minority-group members, often marginalized, to significantly influence the majority group and society.

Multiculturalism and Colorblindness as Threats to the Self: A Framework for Understanding Dominant and Non-Dominant Group Members' Responses to Interethnic Ideologies

Both multiculturalism (which involves recognizing and appreciating differences) and racial/ethnic colorblindness (which can involve emphasizing similarities or individual characteristics) are intended to promote intergroup harmony. Nevertheless, these ideologies can backfire when salient. Although this work has sometimes been interpreted to suggest that dominant group members may perceive salient multiculturalism, and non-dominant group members may perceive salient colorblindness, as threatening, it is unclear what about these interethnic ideologies poses a threat and why. The present article draws upon theories of the self-concept to introduce a framework of Multiculturalism and Colorblindness as Threats to the Self. Specifically, it is proposed that multiculturalism (colorblindness) is potentially threatening to dominant (non-dominant) group members' collective, relational, and personal selves. Dispositional and contextual variables that may moderate perceptions of threat among members of dominant and non-dominant groups, alternative interethnic ideologies to multiculturalism and colorblindness, and potential future research directions are discussed.
