The Logic and Framework for Efficiently Reading People

Understanding people is crucial, yet common judgment methods are easily faked; this article introduces a two‑dimensional framework—situational intensity and incentive pressure—to identify low‑interest, weak‑context scenarios where observed behavior most reliably reveals true character, and offers practical observation principles.
