Mental health, individuals and political models

A systemic reading makes it possible to apprehend the relational systems which govern individuals and their environments. From mental functioning to political systems, Laurent Bibard and Xavier Briffault return to the nature of relational systems and their fundamental role in the construction of individuals and in the perception they have of themselves, of others and of the world.

By analyzing the links between relational systems and models of political systems, Laurent Bibard asks: How is a form of a priori at the origin of extreme liberalism and individualism that pass through fear of others? “Avoiding totalitarianism means relearning to live with each other and no longer individually, against each other. »

Few researches are devoted to the evaluation of the efficiency of therapies and the evaluation methods are often poorly adapted while mental health seems to be at a major impasse. Xavier Briffault returns to the very definition of mental health, often dismissed from its relational nature.

Relearning trust

Mistrust - and therefore the separation of people - becomes systemic when it is assumed as a given.

Since the Renaissance, we have been living in a paradox that is intensifying and becoming global: we are both taken by the evidence of individual freedom as a fundamental value, and by a constitutive distrust of each other: we would only be wolves to each other. Extreme liberalism and totalitarianisms are two sides of the same coin.

Avoiding totalitarianism means relearning to live with each other, and no longer individually against each other.

Laurent Bibard is a professor at ESSEC where he directed the MBA platform from 2005 to 2010. He teaches political philosophy, sociology and economics. Now responsible for the Management and Philosophy sector, he works in particular on the dynamics of vigilance in a crisis situation. He is also Academic Director for ESSEC of the Master Water for All (OpT) deployed in collaboration with ArgoParisTech.

After his work published in collaboration with Edgar Morin, is entitled Complexity and organizations, Facing the challenges of tomorrow (2018), his latest book presents a Phenomenology of sexualities, Modernity and the question of meaning (2021).

Precedence of the relationship and therapeutic efficacy


For several decades, research work has been striving to assess the effectiveness of psychotherapies, without achieving truly convincing results, whether in terms of measuring effectiveness or the mechanisms involved in this effectiveness. A relative consensus seemed to have been established a few years ago around an effect size of around Cohen's d = 0.8 for many disorders, and mechanisms involving both common factors and factors specific to different methods. This effectiveness, already unsatisfactory in view of the massive impact of mental health problems on morbidity and mortality, has yet again been questioned downwards by a recent mega-analysis.  

Leichsenring, Ioannidis et al. analyzing nearly 4000 randomized controlled trials bringing together more than 650,000 people conclude in effect in World Psychiatry that the size of the effect would rather be around 0.35, which is really very low, and is placed at the same level as the effectiveness of psychotropics. Their conclusion is that these results are not contingent: they are definitive, and it must be deduced that (research in) psychiatry and psychotherapy finds itself in a paradigmatic impasse.  

We will take this assertion of a major impasse seriously, and we will examine the hypothesis that it could result from an ontological error, i.e. in the very nature of mental disorders as they are conceptualized in research. experimental study on the effectiveness of therapies for mental health problems. More specifically, failure to consider the inherently relational and situated nature of the human mind may be where the problem lies.  

We will examine this track, and its consequences on the practice of psychotherapy.

Xavier Briffault is a researcher in social sciences and health epistemology at the CNRS (CERMES3). Member of the HCFEA, former member of the HCSP. His research focuses in particular on the categories of understanding in psychiatry/mental health and their consequences on the making of therapeutic and preventive interventions in this field.
