Abstract
Analysis of the activism of experts has ignored the way that scientists form their own overt field-based political struggles to effect change on issues such as race. This article analyzes genomic activism around race, drawing on in-depth interviews with thirty-six leading genomic scientists and discourse analysis of 732 scientific articles. I demonstrate how science activists can fashion themselves as social advocates, by using tactics common to popular politics. These tactics can diverge and detract from popular activism and reify deterministic notions of race. I discuss important theoretical and practical implications for science, social movements, and professions.
