think-tank-dialectic

Hegelian dialectic (Thesis → Antithesis → Synthesis) for irreversible or high-stakes decisions with genuine stalemate — NOT a "better think-tank", a different tool for a different situation. Use when: "this decision is hard to reverse", "both sides have real merit", "genuinely torn between X and Y", "irreversible decision", "real dilemma, not just tradeoffs", "need structured dialectic", "這個決定反悔成本很高", "兩邊都有道理", "在 X 和 Y 之間拉扯", "辯證一下", "不可逆決策", "逃不掉的 tradeoff". Always reach for think-tank first; escalate here only when think-tank's Decision Brief shows LOW consensus AND the decision is costly to reverse. Not for: everyday scope decisions (→ think-tank), pure tech selection (→ survey), reversible tasks where you can iterate, or reflexive "let's debate this" requests.
