Overview
瓶裝水通常是低價值、高可逆性的決策。因此,選擇邏輯學建議使用「夠好」的啟發法 (T2.3),而不是過度投入認知預算。[^1]
Theory anchor: T2.3 (Heuristics for low-stakes reversible decisions)
Step 1 → Clarify the use case (M1)
使用 M1 需求明確化:
-
日常補水 vs 旅行便利性
-
嬰兒配方奶(特殊要求)
-
運動(電解質)
Step 2 → A minimal evaluation frame (M2-lite)
使用簡化的 M2 多維評估 準則:
| Dimension | What it means | Practical heuristic |
|---|---|---|
| safety/compliance | legitimate supply chain | buy from reputable retailers |
| taste | subjective preference | pick what you’ll actually drink |
| value | price per liter | compare unit price |
| packaging fit | portability, storage | match your routine |
Step 3 → Myth filter (consumer immunity)
將具說服力的聲明視為輸入,而非結論:
Standards context (English-world orientation)
Regulatory definitions vary across the U.S./EU/UK and other jurisdictions. Practical takeaway:
-
category names differ; verify what the label legally implies where you live;
-
compliance is a baseline, not proof of “better for everyone.”[^2]
