Many authors discuss about at least two versions of social psychology: one previous and the other posterior to the reference crisis which characterized this area of knowledge in the 70s. The first one had a positivist basis and the second one was committed to transform the society. Most of the times, those texts narrate the history of social psychology highlighting characters, facts and ideas. In this paper, following the methodology proposed by the actor-network theory, we added new elements to this history and discussed the human and non-human actors, the materialities and socialities that contributed to build the Brazilian social psychology. We conclude the text arguing that the reference crisis didn´t eliminate completely the positivist social psychology but substituted it for the “critical” one, because both coexist until today. Therefore, we argue that Brazilian social psychology is complex and that this complexity doesn´t fit into those tenuous time lines we often use to represent the development of academic disciplines
