ABC Theory of Emotion

One-sentence Definition

It is not the event itself that causes emotions, but rather our perception and interpretation of the event that determines our emotional response.

Core Concept

Proposed by Albert Ellis: A (Activating event) → B (Belief/cognition) → C (Consequence/emotional and behavioral outcome). Changing B can change C.

What Problem Does It Solve

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

More specifically, the ABC Theory of Emotion is suited for answering questions like: How can I better understand the current situation? How can I make more reasonable judgments and take appropriate actions?

When to Use

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

When Not to Use

• When the problem is very simple, and direct execution is more important than analysis.
• When basic facts are lacking, and you are just spinning concepts in the air.
• When the model is used only to justify pre-existing conclusions rather than to help refine judgment.

Summary

The key to emotional management is not to change external events, but to change the interpretation and beliefs about those events.
