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.

POPULAR MEDIA AND THE GROWTH OF GENETIC ANCESTRY TESTING

  • 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.

IDENTITY FORMATION THEORIES

  • 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.
