This essay gathers the ideas I presented at the University of Panama, during the Colloquium on Critical Thinking, at the invitation of the Institute of National Studies (IDEN). It is about offering another perspective on critical thinking, which allows analyzing, understanding and evaluating reality, based on knowledge and intelligence to make decisions that can be reasonably supported. A social researcher must have that scientific curiosity to reflectively understand information, question and deepen from their own positions, the solution of problems in a critical way to improve society. Critical Thinking is not a theoretical position in the strict sense of an organized set of ideas that explain a social phenomenon and/or fact. My argument is that critical thinking is an attitude and a skill that every researcher should use when constructing his object of study, to raise the problem of research, to decide the objectives, in the theoretical analysis and in the conclusions.
