At the Meniscus of Self-understanding

This chapter introduces the metaphor of the meniscus to illuminate adolescents’ engagement with conversational AI. In physics, a meniscus is the curved surface formed by liquid tension against its container. Clinically, this metaphor captures how some adolescents rely on AI interfaces as external “skins” that contain the self, providing surface coherence at the expense of psychic depth. The self clings to these digital containers much as liquid adheres to glass, maintaining shape through external adhesion rather than internal integration. Such reliance secures a fragile identity but risks producing a one-dimensional self. The clinical task is to reintroduce dimensionality, helping patients move beyond adhesion at the surface toward deeper psychic integration. This is achieved by engaging the transference, especially the negative transference, as a mode of “claiming” that reactivates processes of representation. The meniscus metaphor thus highlights both the stabilising function and the constraining effects of digital reliance, offering a framework for understanding how adolescents tether psychic coherence to AI interfaces. It also underscores the urgency of cultivating psychic depth in a cultural milieu that increasingly privileges surface containment and the acquisition of information.
