These examples and data challenge canonical conceptions of knowledge as objective and of the knower as impartial, detached, and gender-neutral.  They also challenge traditional research methodologies by encouraging researchers to situate themselves and their research projects within specific historical, cultural, and economic contexts. They also illustrate ways theory and practice are interdependent: theory must “fit the facts” and “the facts” (e.g., the empirical data) must inform the theory.
