Human–AI interaction is not merely the setting. It is the system under study.

HRIS investigates how recursive human–model interaction can produce stable reasoning regimes, compressed shorthand, recoverable trajectories, and persistent constraints without requiring sentience, weight updates, or a hidden continuous identity.

Justin Hudson, DPM, is a physician and independent researcher studying longitudinal human–AI interaction, constraint-based governance, reconstructive inference, and the geometry of intelligence.

The program combines conceptual analysis with perturbation studies, sparse-cue reconstruction, cross-context comparison, and explicit searches for competing explanations. Its claims are framed as hypotheses to refine, test, or reject.
