The phenomenon of widespread genetic ancestry testing has raised questions about its social impact, particularly on issues of race. Some accounts suggest testing can promote bridging social capital – connections between racial groups. In this multi-method paper, we ask whether (1) taking genetic ancestry tests (GATs) and (2) receiving results of African, Asian, or Native American ancestry increases network racial diversity for White Americans. We use a randomized controlled trial of 802 White, non-Hispanic Americans, half of whom received GATs. Unexpected findings show that test-takers' network racial diversity decreases after testing. Using 58 follow-up interviews, we develop and test a possible theory, finding initial evidence that test-takers' network racial diversity declines because they reconsider their racial appraisals of others in their networks.

Demonstrating how race is socially constructed has been a core sociological objective, yet many individuals continue to hold essentialist and other concepts of what races are and how to account for group differences. These conceptualizations have crucial consequences for intergroup attitudes, support for social policies, and structures of inequality, all of which are key sociological concerns; yet much of the research in this area has emerged outside of sociology. Our review of this interdisciplinary scholarship describes the range of views people hold, the attitudes and behaviors associated with them, and what factors contribute to these views. We focus primarily on essentialism and constructivism, although we describe the greater variety of beliefs beyond this dichotomy, as well as fluidity in how people use these concepts. We conclude by presenting research on strategies for reducing essentialist belief systems and identifying key areas for future research. [ABSTRACT FROM AUTHOR]

The genomic revolution is highly relevant to scholarship on racial conceptualization. As genomic research has increasingly focused on small amounts of variation between ancestral groups, it may promote beliefs in racial essentialism. Genetic ancestry tests (GATs) are one of the primary ways the consequences of the genomic revolution are communicated to laypersons, necessitating a better understanding of how test-takers conceptualize race. We analyse 108 in-depth interviews with U.S. and Canadian test-takers to examine how they conceptualize the relationship between race and genes and how they believe GATs influenced their race concepts. We present a typology of racial conceptualization that moves beyond a dichotomy and toward a continuum between social constructivism and genetic essentialism. We also find that test-takers believe GATs reinforce their pre-existing race concepts, regardless of what those were. Our results support an emerging view that people selectively interpret genetic information to confirm rather than transform their race concepts. [ABSTRACT FROM AUTHOR]

The article focuses on the problems associated with categorizing race and ethnicity through census. Topics discussed include the various ways in which the term race is interpreted as shown by international comparisons of census surveys, an illustration through Canadian minority classification of how statistical categories used in surveys and census can create methodological challenges for studying race and the factors that influence people's interpretation of the words race and ethnicity.

Increasing numbers of people in the United States and beyond experience ‘race' not as a single, consistent identity but as a number of conflicting dimensions. This article distinguishes the multiple dimensions of the concept of race, including racial identity, self-classification, observed race, reflected race, phenotype, and racial ancestry. With the word ‘race' used as a proxy for each of these dimensions, much of our scholarship and public discourse is actually comparing across several distinct, albeit correlated, variables. Yet which dimension of race is used can significantly influence findings of racial inequality. I synthesize scholarship on the multiple dimensions of race, and situate in this framework distinctive literatures on colourism and genetic ancestry inference. I also map the relationship between the multidimensionality of race and processes of racial fluidity and racial boundary change. [ABSTRACT FROM PUBLISHER]

This special issue brings together original research that advances the emerging subfield on the measurement and analysis of varying components of race. The articles provide insight into how social scientists can tease apart the multiple components of race and leverage them to better understand how race continues to divide life chances, creatively using existing and new sources of data. The articles speak to three key themes: how we can better understand the various ways that race is experienced, alternative approaches to measuring the different components of race, and the implications of race measures for understanding social inequality.
