Species‑Primacy Behavioral Model

Behavior is best modeled as a two‑input function—the adaptively relevant situation plus an individual instantiated from a universal species design (p_s → p_i). The model emphasizes that species‑typical architecture often explains more of behavior than idiosyncratic personal history, while noting prediction remains hard because situations vary and individuals are calibrated. — Using a compact, mechanistic formula to describe behavior reframes responsibility, policy interventions, and prediction (e.g., criminal justice, public‑health messaging, education) by clarifying when situation redesign beats personality targeting.
