Objective This article proposes to rethink social psychology based on indigenous knowledge, considering that it interrogates the policies of subjectivation derived from the binary conception of nature and culture that underpins modernity. Method This is a theoretical article that analyzes indigenous contributions to the decoloniza-tion of psychological thought, considering the context of climate change. The scope of what is understood as social is problematized, as well as to whom subjectivity is attributed or not in psychology. Results Psychology reproduces Western dichotomies by being based on a fixed nature, ex-ternal to itself, whose social nature is conceived based on human exceptionalism. For people who understand life as the effect of relationalities between human and non-human beings, these categories do not make any sense. Conclusion The complexity of knowledge and indigenous protagonism in the fight for land and territory in a context of climate change point to the urgency of reterritorializing social psychology.
