Inclusivity is a concept understood through the relationships between people in fields of power. It is a historically rooted and situated idea, intertwined with the developmentalist model of modernity and epistemic colonialism. This concept, historically rooted in the notion of “inclusion,” has evolved from an educational concept to a broader social perspective, aiming to establish a standard format through international treaties and models. However, it has also involved aspects such as exclusion and discrimination. While it encompasses ontological dimensions, it is primarily an epistemological concept, as it involves naming differences, situating them, and shaping forms of relationship—even in ways that critically examine perspectives aligned with human rights and social justice. Psychology has contributed little to the development of this idea; rather, it has often justified difference and its exclusion. Its potential lies in moving beyond categorical views and embracing the proliferation of difference as an epistemic framework.
