This article seeks to contribute to the discussion of the trajectories and situations of individuals in the context of incarceration and institutionalized protection, drawing from the thoughts of Edgar Morin. It aims to engage in the current public policy debate, socioeducational work, and research in these contexts. Ideas from complex thinking are highlighted in conjunction with empirical evidence of incarceration situations. What this initial problematic analysis reveals is that the interventions and paths presented in these contextsdo not permeate Morin's interrogated complexity of building and, as a reference to his thinking, discovering new knowledge and developing awareness to address and prevent incarcerations, leading to transformations in individuals. The trajectory of incarcerations places us on the plane that we must analyze, map, and interconnect multidisciplinarily what is established, the processes, while also questioning the flaws, what is invisibilized, what is excluded, to modify the dire consequences of what incarcerations generate and consider them in complexity.
