The objective of knowing your enneagram type is to help you know yourself better and to enrich your personal development. There is no “better” or “worse” type. Each type and each person has their own assets.
The enneagram is a model that structures human personality based on 9 different types of functioning that relate to the direction of three centres of intelligence (mental, emotional and instinctive) that we all have. Each enneagram type is based on unconscious fears, desires to compensate them and expresses a unique way in which the three centres of intelligence interact between each other.
The enneagram is absolutely not just a simple personality test that categorises 9 different types of functioning: it uses a neighbouring group participation system (the wings) and several levels of healthiness at the heart of each type (which can lead towards an integration or a disintegration type). Thus, two people of the same type, depending on how they manage their compulsions and the degree of influence of neighbouring types, can be very different.
