Maslow’s Hierarchy of Needs

One-Sentence Definition

Human needs are divided into five levels, from physiological to self-actualization, and higher-level needs are pursued only after lower-level needs are satisfied.

Core Concept

Five levels of needs: Physiological needs → Safety needs → Social needs → Esteem needs → Self-actualization needs. Lower-level needs take priority.

What Problem Does It Solve

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

More specifically, Maslow’s Hierarchy of Needs is suited for answering questions like: How can I better understand the current situation? How can I make more reasonable judgments and take more appropriate actions?

When to Use

• When problems become complex and intuitive judgment is no longer reliable.
• When the team disagrees on next steps and needs a shared analytical framework.
• When you need to translate abstract judgments into concrete actions, checklists, or experiments.
• When existing practices are losing effectiveness and you need to re-examine the underlying logic.

When Not to Use

• The problem is simple, and direct execution is more important than analysis.
• Basic facts are lacking, and you are merely spinning concepts in the air.
• The model is used only to justify existing conclusions, rather than to help correct judgment.

Summary

Understanding the hierarchy of needs can help you assess the behavioral motivations of yourself and others, as well as how to design products and services.
