# Dual-System Thinking (System 1 / System 2) ## Overview Two parallel modes: **System 1** — fast, automatic, effortless (pattern recognition, gut feel). **System 2** — slow, deliberate, effortful (analysis, computation, critical evaluation). System 1 runs ~95% of decisions by default; System 2 engages only when recruited. Most cognitive biases are System 1 shortcuts misapplied where System 2 should have intervened. Composes with [`metacognition`](../metacognition/SKILL.md), every cognitive-bias skill ([`anchoring`](../anchoring/SKILL.md), [`confirmation-bias`](../confirmation-bias/SKILL.md), [`availability-heuristic`](../availability-heuristic/SKILL.md), etc.), [`deep-work`](../deep-work/SKILL.md), and [`wu-wei`](../wu-wei/SKILL.md). ## When to Use - Decision feels obvious and is high-stakes; unfamiliar domain + fast intuition; time pressure on consequential matter; team converging without stress-test; depleted (tired/hungry/pressured) - Designing a process or interface that depends on user attention **Not when:** routine low-stakes decisions; calibrated expert System 1 in this exact domain; emergency requiring speed. ## Coaching Novices (Adaptive Front Door) - **Engine mode:** user has a concrete decision → run The Process directly. - **Coach mode:** user is unfamiliar → guide step by step. In Coach mode, respond one step at a time. Each [WAIT] is a hard stop — output only that step's question, then stop. 1. One-line: when a high-stakes decision feels obvious, that
