Objectivity is widely recognized as a fundamental value in the sciences. Yet objectivity may be deployed as a filter or screen that discourages scientists from reflecting on the political consequences of their work. This article examines the relationship between scientific commitment to objectivity and recent critiques of the influence of corporations on research. It does so by analysing legal documents and examples of ‘life writing’, including a prominent environmental sociologist’s candid reflections on his decision to consult for Exxon after 1989 Valdez oil spill in Alaska. The article considers how objectivity may facilitate participation in research intended to promote doubt and uncertainty about the harm caused by corporations. It asks whether such decisions are better understood as unavoidable blind spots or examples of wilful blindness. © The Author(s) 2020.
