The document discusses openness as an organizing principle and examines its dual nature as both inclusionary and exclusionary. It explores how openness is defined in terms of transparency and inclusion, but notes tensions arise from practices that can exclude certain actors. Two explanations for the lack of diversity in open organizations are proposed - imported exclusion from broader societal inequalities, and created exclusion through behaviors within the community. The document questions how to resolve the paradoxical nature of openness and proposes analyzing it together with closure as interdependent and both necessary for strategic organization. It concludes by asking how researchers can best investigate the dual character of openness.
