STEP: 1515 / 公開日: 2026-08-28 / Test: 28/28 PASS / Lean 4: 7 theorem zero sorry / Type: STEP 1504 認知科学 arc candidate #1 実装 (cognitive science domain 未着手 first)
❶ Kahneman-Tversky dual-process theory: System 1 (直感) と System 2 (熟考) の 出力 → verdict。 一致 → TRUE (double confirmation)、 不一致 → BOTH (dual-process conflict ★)、 unavailable → NEITHER。
❷ Generic type: string / number / boolean 全対応、 T generic parameter で 型 preserve。
❸ 10 姉妹 verdict tool 目 (cognitive science domain 未着手 first)。
| # | Condition | Verdict | Reason |
|---|---|---|---|
| 1 | 両方 null/undefined | NEITHER | neither_active |
| 2 | system1 のみ available | TRUE | s1_only_available |
| 3 | system2 のみ available | TRUE | s2_only_available |
| 4 | 両方 present, 出力一致 | TRUE | both_agree_double_confirm |
| 5 | 両方 present, 出力不一致 | BOTH ★ | dual_process_conflict |
// A: neither → NEITHER
dualProcessVerdict({});
// { verdict: 'NEITHER', reason: 'neither_active', agreedAnswer: null }
// B: s1 only → TRUE (intuitive answer available)
dualProcessVerdict({ system1: 'gut says A' });
// { verdict: 'TRUE', reason: 's1_only_available', agreedAnswer: 'gut says A' }
// C: both agree → TRUE (double confirmation)
dualProcessVerdict({ system1: 42, system2: 42 });
// { verdict: 'TRUE', reason: 'both_agree_double_confirm', agreedAnswer: 42 }
// D: both disagree → BOTH ★ dual-process conflict
dualProcessVerdict({ system1: 'gut_says_X', system2: 'thought_says_Y' });
// { verdict: 'BOTH', reason: 'dual_process_conflict', agreedAnswer: null }
// = 直感 と 熟考 が 分かれた case、 追加 熟考 or 判断保留 discipline
// Generic: boolean type
dualProcessVerdict<boolean>({ system1: true, system2: false });
// { verdict: 'BOTH' }

❶ 単純 equality 判定のみ (semantic similarity は 呼び出し側)。 「gut says X」 vs 「gut is X」 の semantic 一致は 判別しない (文字列 strict compare)。
❷ Kahneman-Tversky theory は 診断的 mapping、 real cognitive architecture (dual-process model 論争 Evans-Stanovich 等) 未 embed。
❸ 「世界初」 なし = Kahneman 2011 既知 の D-FUMT₈ verdict mapping。 novelty = 10 姉妹 tool 統一 API 拡張。
❹ 累計 defer 42 → 41 (本 tool 実装)。
