Guest Editorial: Conceptualizing Justice and Counter-Expertise.

Systemic injustices exclude counter-experts from telling their stories and influencing the collective imagination. Four papers and some discussant essays illustrate the ways in which counter-experts cross boundaries to contest knowledge claims, legal institutions, and forms of data in order to resist various forms of injustice. Literature on counter-expertise, socio-technical imaginaries, and epistemic injustice highlights how marginalized groups are prevented from participating in the process of collective imagining. A definition of counter-expertise and a new typology of counter-expertise demonstrate how marginalized groups navigate boundaries to pursue epistemic justice. The four papers in the special issue exemplify the ways in which counter-experts navigate identity politics. To combat epistemic injustice within our field, STS scholars can be more inclusive with teaching, mentoring, reviewing and other forms of scholarly gatekeeping. [ABSTRACT FROM AUTHOR]
