The post-rationalist psychotherapy academy (non-classic cognitive approach) started at the end of the 80's with a series of consistent hypotheses. It is an academy which stems from contemporary psychotherapy and develops different areas, giving a strong contribution to theoretical and clinical psychotherapy. This academy has presented development as all other psychotherapy schools have, as well as the same difficulties and solutions. In this article, our aim is to show some tendencies that don't present an epistemological, theoretical, methodological and coherency, since these tendencies don't allow any confutation, which is the fundamental premise of Vittorio Guidano's academy. Finally, we stress how it's nowadays crucial in psychotherapy, to apply coherent methodological and conceptual positions based on the research.
