How many emotions does the DES measure?

The Differential Emotions Scale measures 10 distinct emotions: interest, joy, surprise, sadness, anger, disgust, contempt, fear, shame, and guilt. Rather than collapsing everything into "good" or "bad," it lets you see exactly which emotions are active and how intense each one is.

The Differential Emotions Scale was developed by psychologist Carroll Izard as part of his differential emotions theory, which proposes that a small set of basic emotions each carry their own signal and function. It has been used in emotion research for decades.

Is a DES score a diagnosis?

No. In Beliora, the DES is a tool for self-understanding — helping you name and track feelings — not a clinical diagnosis. Beliora does not diagnose, treat, or cure any condition, and it is not a substitute for professional care. For assessment, see a licensed professional.

The DES emotion scale, in plain words

The Differential Emotions Scale (DES), developed by psychologist Carroll Izard, is a research-based way to measure feelings across 10 distinct emotions: interest, joy, surprise, sadness, anger, disgust, contempt, fear, shame, and guilt. Instead of rating your mood as simply "good" or "bad," the DES helps you see exactly which emotions are present and how strong each one is. Beliora uses it to make a vague feeling specific — it is a self-understanding tool, not a diagnosis.

The 10 emotions, and why they matter

The DES separates feelings that usually blur together — sadness from shame, fear from anger. That distinction matters, because shame and sadness ask for different responses. Naming the specific emotion is the first step to understanding it. Beliora scores each of the 10 emotions so you can see the real shape of a "bad day."

Where the DES comes from

The scale grew out of Carroll Izard’s differential emotions theory, which holds that a small set of basic emotions each have their own signal and function. It has been used in emotion research for decades. Beliora applies it as a practical, everyday lens — not a clinical instrument — to help you track your feelings over time.

How Beliora pairs DES with a Tone Scale

Alongside the 10 DES emotions, Beliora tracks a single Tone Scale from 0 to 4, running from apathy up to enthusiasm. The DES tells you which emotions are present; the Tone Scale captures your overall charge. Together, watched over 30 days, they turn scattered feelings into a pattern you can actually read.
