Granularity of Emotions

How It Works

The 4 Core Emotion System  (4CES) labels feelings using four uniquely expressed core emotions, which are also globally accepted as general states of being. These core expressions of emotion are joy, fear, sadness and anger. 4CES blends the expressed emotion in natural language by related biological changes and states of thought. This simplifies and empowers emotional intelligence on a global scale and aligns with modern digital communication.

Joy

a feeling of great pleasure and happiness

Fear

an unpleasant emotion caused by the belief that someone or something is dangerous, likely to cause pain, or a threat.

Sad

feeling or showing sorrow; unhappy

Anger

a strong feeling of annoyance, displeasure, or hostility.
