The Enneagram is a model of personality that describes nine distinct types or strategies for relating to the self, others and the world. Each person has one dominant type, and additionally may have traces of other types more strongly, known as wings. Beyond the primary Enneagram and wings, there is a concept of Tritype, introduced by Katherine Chernick Fauvre, where three Enneagram types are identified – one from each of the three centers (thinking, feeling, and instinctive).

The 5-3-1 Tritype involves types from the “head” (5), “heart” (3), and “gut” (1) centers, respectively.

  • Type 5: The Investigator – People with a core Type 5 are often cerebral, curious, and independent. They strive for knowledge and understanding, often preferring to observe from the sidelines rather than actively participate. Can tend to be isolated and somewhat introverted.
  • Type 3: The Achiever – People with a core Type 3 are driven, adaptive, and image-conscious. They have a lot of ambition and tend to be very focused on their goals. They are usually pragmatic and good at achieving their goals.
  • Type 1: The Perfectionist – People with a core Type 1 are rational, principled, and want to do the right thing. They have a strong sense of duty and naturally see how things could be improved. They tend to have high standards and can be self-critical and perfectionistic.

In this 5-3-1 Tritype, the primary type is 5, which means the desire for knowledge and understanding is strongest. The secondary influence of type 3 reflects motivation to succeed and achieve, and a certain image-consciousness, while the influence of type 1 means that there is also a strong drive for integrity and perfection.

This combination might make for someone who is intensely focused on their pursuits, detail-oriented, and self-reliant. However, they might struggle with isolation or alienation due to their inner focus and self-sufficiency. They could also be perfectionistic and may stress themselves out in trying to meet high standards.

Remember, all these traits can manifest both in healthy and unhealthy ways depending on personal development and other circumstances. The Enneagram, and especially the system of Tritypes, provides a useful tool for self-awareness and personal growth rather than fixed labels or limits.
