PhronesisNomophobia — the fear of being without one's mobile phone or internet connection — is here formally reconceptualized as a wrong attractor W_NP in the landscape of embodied presence. The healthy ground state S^0 is defined as embodied presence: the capacity to be fully in the physical world and present to immediate experience without digital mediation, able to tolerate periods of disconnection without distress.
W_NP is rigorously distinguished from professional digital necessity, appropriate connectivity, and healthy technology use. Three interlocking mechanisms maintain the basin: connectivity as ground state substitution (the phone/network becomes the primary anchor for identity, orientation, and safety, replacing embodied and relational anchoring — being online becomes S^0 in subjective experience), variable reward entrainment (notification streams operate on variable-ratio reinforcement schedules — the most potent known schedule for behavioral conditioning — maximizing checking frequency and deepening the basin), and the FOMO-proximity loop (disconnection triggers fear of missed events or information; the loop reconnect → brief relief → fear of what else happened → check again → is self-maintaining).
The Presence Paradox is central: constant digital connectivity produces the disconnection — from self, body, others, place — it is organized to prevent. Nine formal propositions characterize the embodied presence ground state, the digital-tether wrong attractor, the three maintenance mechanisms, the presence paradox, developmental roots in the attention economy, and return paths through digital minimalism, embodied practices, and attention restoration.
