Constructing identities: the implications of DTC ancestry testing for tribal communities

Direct-to-consumer (DTC) genetic ancestry companies have rapidly increased in popularity, with top testing services maintaining genetic databases of several million consumers. While genetic ancestry tests are often characterized as recreational, companies invoke deeply personal concepts of individual identity, group membership, and kinship when marketing their services. In particular, many companies claim to be able to determine Native American heritage, claims that are not supported by the state of the science and may have significant cultural and political consequences for US tribal communities. This study aims to fill the gaps in empirical work on this issue and characterize how genetic ancestry companies articulate indigenous identity through their marketing strategies.

We conducted a qualitative content analysis of the public facing websites for 25 DTC genetic ancestry companies that offer services measuring Native American ancestry.

Our findings describe how genetic ancestry companies promote a causal relationship between genetics and self-identity through marketing language such as "Discover Yourself" and "Are you Native American?" and how this may affect US tribal communities.

Genetic ancestry company claims regarding genetic ancestry, personal identity, and cultural membership are problematic and challenge how US tribal nations currently identify and create potential obstacles for tribal sovereignty.
