Substitute Decision-Making

One-Sentence Definition

Imagine how another person would make a decision when faced with the same problem, thereby stepping out of your own cognitive limitations.

Core Concept

The substitute decision-making method: If the person you admire most were facing this decision, what would they do? Use role-playing to reduce emotional interference.

What Problem Does It Solve

When information is incomplete, options are numerous, or risks are unclear, it helps shift your judgment from intuition to structured analysis.

More specifically, substitute decision-making is suitable for answering questions like: How can I better understand the current situation? How can I make more reasonable judgments and take action?

When to Use

• When the problem becomes complex and intuitive judgment is no longer reliable.
• When the team has disagreements on the next steps and needs a common analytical framework.
• When you need to turn abstract judgments into concrete actions, checklists, or experiments.
• When existing practices are declining in effectiveness and the underlying logic needs to be re-examined.

When Not to Use

• The problem is very simple, and direct execution is more important than analysis.
• Basic facts are lacking, and you are just spinning your wheels on concepts.
• The model is used only to prove existing conclusions, rather than to help correct judgment.

Summary

Step out of your own perspective and view the problem from someone else’s standpoint to gain more objective judgment.
