 Feminist perspectives encompass more than equity issues however. They extend to questions about the methodology, epistemology, and ontology of scientific inquiry as well. Feminists have scrutinized explicit ways that scientific research has been affected by sexist and gendered presuppositions about the subject matter and the methods appropriate to the sciences. Such investigations have sometimes revealed how scientific practice has failed to meet standards of good science. Additionally, and more radically, feminists have questioned traditional methodologies and offered alternative approaches better suited to feminist subject matter and goals. Feminist perspectives on scientific knowledge production have been constructive where criticisms have motivated alternative conceptualization of subject matter, greater attention to the goals of scientific research, and reflection on the epistemological and ontological commitments of methodology.
