-# Habit Formation (습관 형성의 심리학)
+# Habit Formation

-## 📌 한 줄 통찰 (The Karpathy Summary)
-> "의지력을 자동화된 루틴으로 대체하라" — 반복적인 행동을 통해 뇌의 신경 회로가 재편되어, 최소한의 인지적 노력만으로 특정 행동을 수행하게 되는 심리적 과정.
+## 매 한 줄
+> **"매 habit = cue → routine → reward 의 basal-ganglia automatization"**. 매 21-day myth 의 false — Lally 2010 의 median 66 days (range 18-254). 매 2026 의 wearables + LLM coaching + JITAI (just-in-time adaptive intervention) 의 active.

-## 📖 구조화된 지식 (Synthesized Content)
- **추출된 패턴:** 신호(Cue) -> 반복 행동(Routine) -> 보상(Reward)으로 이어지는 '습관 고리(Habit Loop)'를 형성하여 의사결정 에너지를 절약하는 인지 패턴.
- **세부 내용:**
-    - **Basal Ganglia:** 습관이 저장되는 뇌 부위. 전전두엽의 개입 없이도 행동을 실행하게 함.
-    - **Implementation Intentions:** "X 상황이 오면 Y를 하겠다"는 구체적 계획이 습관 형성 성공률을 높임.
-    - **Keystone Habits:** 하나의 작은 습관이 연쇄적으로 다른 긍정적 변화를 일으키는 핵심 습관 (예: 운동, 독서).
-    - **[[Neuroplasticity|Neuroplasticity]]:** 반복을 통해 시냅스 연결이 강화되는 뇌의 가소성 원리.
+## 매 핵심

-## ⚠️ 모순 및 업데이트 (Contradictions & Updates)
- **과거 데이터와의 충돌:** 단순히 "21일이면 습관이 된다"는 속설과 달리, 행동의 복잡도에 따라 평균 66일에서 길게는 수개월이 걸릴 수 있음이 현대 심리학에서 증명됨.
- **정책 변화:** Antigravity 에이전트의 사용자 인터랙션 설계 시, 사용자가 매일 지식 가드닝에 참여할 수 있도록 명확한 '신호'와 '보상' 체계를 제공하여 습관화를 유도함.
+### 매 habit loop (Duhigg / Wood)
+1. **Cue**: 매 trigger — time, place, emotional state, preceding action, people.
+2. **Routine**: 매 behavior 자체.
+3. **Reward**: 매 reinforcement — neural prediction error.
+4. **Craving** (Wood addition): 매 anticipation 의 cue→reward.

- **Raw Source:** 10_Wiki/Topics/AI/Habit-Formation.md
+### 매 neural substrate
+- **Goal-directed**: 매 prefrontal + dorsomedial striatum — early learning.
+- **Habitual**: 매 dorsolateral striatum (sensorimotor loop) — automatization.
+- **Switch**: 매 overtraining + stable context → habitual takeover.

-## 🤖 LLM 활용 힌트 (How to Use This Knowledge)
+### 매 formation 의 핵심 levers
+- **Implementation intentions** (Gollwitzer): "When X, I will Y" — 매 효과 size large (d ≈ 0.65).
+- **Context stability**: 매 same time + place 의 consistency.
+- **Friction reduction**: 매 cue salience ↑, 매 obstacle ↓.
+- **Temptation bundling** (Milkman): 매 desired + pleasurable 결합.
+- **Identity-based**: 매 "I am someone who..." (Clear).

-**언제 이 지식을 쓰는가:**
- *(TODO)*
+### 매 응용
+1. Atomic Habits 의 4 laws (obvious, attractive, easy, satisfying).
+2. Health behavior change (exercise, medication adherence).
+3. Productivity (deep-work blocks).
+4. Habit-stacking (after-X-then-Y).

-**언제 쓰면 안 되는가:**

-## 🧪 검증 상태 (Validation)
+### Habit tracker (streak + context)

+    return f"When {cue}, I will {action} in service of {goal}."

+### Habit-stacking chain
+```python
+def stack(anchor: str, new_habit: str, reward: str | None = None) -> dict:
+    return {
+        "anchor": anchor,
+        "new_habit": new_habit,
+        "rule": f"After {anchor}, I will {new_habit}.",
+        "immediate_reward": reward,
+    }
+```
+
+### JITAI delivery decision
+```python
+def jitai_should_deliver(state: dict) -> bool:
+    """Deliver intervention only when receptive + context-matched + low burden."""
+    return (state["stress"] < 0.7
+            and state["cognitive_load"] < 0.6
+            and state["context_match"] > 0.8
+            and state["recent_interventions_24h"] < 3)
+```
+
+### Lally formation curve
+```python
+import numpy as np
+
+def automaticity(day: int, asymptote: float = 0.95, k: float = 0.04) -> float:
+    """Asymptotic automaticity (Lally 2010 fit)."""
+    return asymptote * (1 - np.exp(-k * day))
+# day 21 → ~0.58, day 66 → ~0.88
+```
+
+### Context-cue salience score
+```python
+def cue_salience(cue: dict, history: list[dict]) -> float:
+    """Higher when cue co-occurs with successful routine."""
+    matches = [h for h in history if all(h.get(k) == v for k, v in cue.items())]
+    if not matches:
+        return 0.0
+    return sum(h["completed"] for h in matches) / len(matches)
+```
+
+## 매 결정 기준
+| 상황 | Strategy |
+|---|---|
+| Brand-new habit | implementation intention + context stability |
+| Existing routine + new addition | habit stacking (anchor) |
+| High-friction habit | reduce friction first, then add cue |
+| Reward-poor habit | temptation bundling |
+| Identity-level change | identity-based ("I am the kind of person who...") |
+| Relapse prevention | re-stabilize context, restore cue |
+
+**기본값**: 매 implementation intention + same context daily + 60-90 day window. 매 21-day promise X.
