Conscious and unconscious gender bias permeates society and continues to limit women’s participation and advancement even when equality has been legally established. This literature review, authored by Insight’s military and veteran support team, and conducted for the Defense Advisory Committee on Women in the Services (known as DACOWITS), reviews the academic foundations of bias; media coverage on gender bias within the U.S. military; and how gender-inclusive wording has been adapted within the U.S. military, foreign militaries, and U.S. commercial workplaces and civilian industries. The paper concludes by identifying best practices and strategies to address conscious and unconscious gender bias through gender-inclusive wording and policies.
