This article calls for a retheorizing of boundary-work that engages more actively with feminist, critical race, and postcolonial scholarship and examines more systematically the relation between scientific boundary-work, broader structures of sociopolitical inequality, and boundary-workers¡¯ (embodied) positionality. To demonstrate the need for this retheorization, I analyze ethnographic and interview data on scientific boundary-work in the natural and social sciences in Portugal, showing that scholars¡¯ gender, sexuality, race, ethnicity, and nationality affect the success of their boundary-work. I suggest, therefore, that in unequal societies where credibility is unevenly distributed, the conditions are not in place for some scholars¡¯ boundary-work to work. I draw on Sara Ahmed (and J. L. Austin) to argue that we must conceptualize scientific boundary-work as always potentially performative, but not always successfully so, and explicitly interrogate the actual conditions of performativity. Recognizing the links between inequality, embodiment, and non-performativity in scientific boundary-work will enable STS to better understand, and hopefully transform, the relations between contingent struggles over scientificity and entrenched structures of power %K academic disciplines and traditions %K expertise %K epistemology %K genders %K justice %K inequality %K protest %K other %U https://journals.sagepub.com/doi/full/10.1177/0162243918795043
