Reality check. The issue of social plausibility in Virtual reality therapy with addiction patients.

In France, virtual reality has been experimented since 2016 to address addictive behaviors. The existing literature insists on the "immersive" dimension of the technology as a significant factor in the efficacy of exposure. An ethnographic approach, however, suggests that the realism criterion should be reassessed. Based on a fieldwork conducted in the addictology department of a French hospital that made use of Virtual reality therapy (VRT), the article shows that it is a form of technical reiteration designed to develop reflexivity about one's actions, provoking the craving so that it can be domesticated. The patient's engagement in "as if" mode is facilitated by the therapist's work in mapping the patient's addictive practices, personalizing the exposure situations, and elaborating the simulation as being part of a practical experiment. While the question of graphic realism does not seem especially problematic, the question of social plausibility can put the simulation operation under strain.
