Study Notes on Genetic Ancestry Testing and Identity
INTRODUCTION TO GENETIC ANCESTRY TESTING
- Authors: Wendy D. Roth and Biorn Ivemark
- Institution: University of British Columbia
- Context: The rise in genetic ancestry testing has raised concerns about how it impacts consumers' racial and ethnic identities, potentially creating "geneticized" identities.
- Methodology: Base of 100 qualitative interviews from various racial and ethnic groups, including white, black, Hispanic/Latino, Asian, and Native Americans.
- Genetic Options Theory: Proposed to explain how genetic ancestry tests affect ethnic and racial identities by analyzing two main mechanisms: identity aspirations and social appraisals.
- Findings indicate that genetic testing often reinforces race privilege among those already experiencing it.
- Media Examples:
- Oprah Winfrey on the show African American Lives discovered roots in Liberia, Cameroon, and Zambia.
- Jessica Alba on Finding Your Roots found genetic ancestries including European, Native American, African, and Jewish.
- Industry Growth:
- Post-human genome decoding, 74 companies emerged specializing in genetic ancestry tests, engaging over 4 million people. Revenues now exceed billions.
- Public Influence: Media coverage and sharing results among users greatly affects public perceptions regarding ancestry testing.
IMPACT OF GENETIC ANCESTRY TESTING ON IDENTITIES
- Identity Formation Hypothesis:
- Some scholars argue tests will transform identities as genetic data holds scientific authority.
- Others, referencing social identity theory, suggest individuals may selectively incorporate or reject data based on how they wish to be perceived.
- Key Terms:
- Geneticized Identity: New identities formed primarily through genetic knowledge.
- Selective Geneticization: The process by which consumers choose from genetic options based on desires for identity versus acceptability by social peers.
METHODOLOGY OF STUDY
- Data Collection: Interviews conducted across the country focusing on identity development pre- and post-testing.
- Follow-Up Strategy:
- Researched identity stability through follow-ups 18 months later.
- Interview Process: In-depth explorations of identity changes resulting from genetic tests.
DEFINING RACE AND ETHNICITY
- Race: A cognitive structure sorting individuals into categories based on perceived inherent characteristics, especially biological or physical traits.
- Ethnicity: Constructs groups by shared ancestry, history, and cultural symbols.
- Overlap: Scholars note that the definitions often blur, but distinctions remain relevant, particularly in American society.
- Genetic Determinism Theory: Argues tests directly and strongly determine identities for test-takers.
- Critics assert this neglects individual interpretation of genetic information.
- Social Identity Theory: Suggests that people's identities are influenced by social appraisals and aspirations to attain positively valued identities.
MECHANISMS OF IDENTITY CHANGE
- Identity Aspirations: Reflects the identities consumers desire or wish to claim. Influences include:
- Private regard towards an identity versus public perceptions of identity.
- Social mobility among groups, where individuals may seek a different identity based on their social context.
- Social Appraisals: The assessments individuals make regarding how likely their new identity will be accepted by others based on outward appearance, personality, and group stereotypes.
RESPONSES TO GENETIC ANCESTRY TEST RESULTS
- Emphasis on Selectivity: Consumers may incorporate new identities selectively based on aspirations and appraisals of social acceptance.
- Stability of New Identities: In follow-ups, 91% of interviewees reported unchanged identities from prior testing.
GROUP PATTERNS IN IDENTITY CHANGE
- White Respondents: Most likely to incorporate new identities. Their motivations include a desire for excitement or exoticism to counter feelings of blandness in their identity.
- Black and Latino Respondents: Less likely to change as identities are often already diverse (multiraciality incorporated); new ancestries rarely challenge established identities.
CONCEPTUALIZING TESTING LIMITATIONS AND SCIENTIFIC UNDERPINNINGS
- Misinterpretation of Results: Genetic ancestry tests often misrepresent ancestry, with significant limits and assumptions that may not be fully communicated to consumers.
- Testing Procedures:
- Y-DNA and mtDNA assess paternal and maternal lines respectively, offering ancestral migration pathways based on genetic variation.
- Admixture tests calculate percentage contributions from different ancestral backgrounds across the genome.
CONCLUSIONS
- Genetic options theory nuances the understanding of genetic ancestry testing impact, suggesting it is not a straightforward determinant of identity, but a mechanism filtered through sociocultural contexts.
- The broader implications highlight how testing influences demographic trends and potential shifts in racial identification, particularly among white respondents who may adopt symbolic racial identities without facing structural implications.
