What's your behavior style?

Q: What is the DISC test?

It is a self-knowledge tool based on William Marston's model (1928), which describes behavior tendencies across four styles: Dominance, Influence, Steadiness and Caution. It is not a psychological diagnosis.

Q: How long does it take?

About 5 to 7 minutes. There are 28 statements answered on a 1-to-5 scale.

Q: Can I have more than one style?

Yes, and it is the most common case. Almost everyone blends two or more styles. The result shows the intensity of all four and highlights your dominant territory.

How you act, decide and relate — across Dominance, Influence, Steadiness and Caution. Free, no sign-up, instant result.

The DISC test, based on William Marston's model (1928), describes behavior across four styles: Dominance, Influence, Steadiness and Caution. Studies show almost no one is a pure style — most people blend two or three. Here there are 28 statements on a 1-to-5 scale; the result is a self-knowledge estimate, not a diagnosis.

How it's calculated — and the science

The DISC model began with the psychologist William Moulton Marston in Emotions of Normal People (1928), a work now in the public domain. Marston described how people respond to their environment along two axes: the environment is seen as favorable or challenging, and the person reacts in a more active or measured way. From that come four styles.

Each of the 28 statements adds points (from 1 to 5) to one of the four styles — 7 statements per style. We convert each style's total into an intensity percentage and highlight the dominant one. You're almost never “pure”: the norm is a blend of two styles.

Reliability · limitsDISC-type instruments enjoy wide practical acceptance, but a more modest empirical basis than the Five-Factor model (Big Five). They're useful for reflecting on communication and work style — not for predicting performance or screening people. Treat the result as a snapshot of the moment, one that changes with context and life stage. Reference year: 2026.

Author's note

DISC was the first test I built here, and the hardest to keep honest: it's popular precisely because it's simple — and too simple turns into a label. I kept Marston's four styles (1928) but rewrote every statement to sound like a person talking, not an HR manual. If a result describes you badly, that's exactly the feedback I want.
