Qu'est-ce que Enneagram ?

Definition

The Enneagram is a personality typology model describing nine fundamental character types, each characterised by a core motivation, a basic fear, and a central defence mechanism. The nine types are connected by a geometric figure (the enneagram) with lines indicating stress and growth directions. Unlike most personality models, the Enneagram places strong emphasis on the unconscious motivations that drive behaviour rather than observable traits.

In practice

In organisational settings, the Enneagram is used primarily in coaching, leadership development, and team dynamics workshops. Its strength lies in fostering deep self-reflection and understanding of why people behave as they do under different conditions. However, its scientific credentials are far weaker than the Big Five — there is limited peer-reviewed evidence for its reliability and validity. It should never be used as a hiring or promotion decision tool. Professional coaches use it as a framework for meaningful conversations about growth patterns, stress responses, and interpersonal dynamics, where participants often find it resonates deeply even if scientifically contested.

Key takeaway

The Enneagram can be a powerful coaching and self-awareness tool — but keep it in the development space and away from selection decisions where scientific validity is required.
