Abstract
<jats:title>Abstract</jats:title> <jats:p>This chapter focuses on another key aspect of good moral relations: To be full members of the moral community, individuals need to be recognized as knowers. Under scientific chauvinism, people without scientific credentials may be denied that recognition; in contrast, reparative science works to secure people’s status as knowers. Activists’ use of bucket air samplers offers an example. It helped establish residents of communities near petrochemical facilities as knowers by turning their observations of everyday pollution into things worth knowing about, by involving them in judgments about knowing well, and by enabling them to hold scientists directly accountable for their knowledge claims. The chapter concludes by arguing that new technologies for knowing about injustice should be judged not by how much data they generate, but by the extent to which they counter the exclusion of marginalized groups from processes of knowing and assert their status as knowers.</jats:p>
