The Enneagram's Link with Neuroscience Over Time
Introduction
Did you know the Enneagram and neuroscience have followed remarkably similar journeys to understand the human mind and personality? For the last 25 years, I've been closely observing the evolution of the Enneagram alongside developments in neuroscience, especially through the lens of psychotherapy. This journey has revealed fascinating parallels, particularly intriguing because the Enneagram is often not recognized within scientific circles.
In the 1960s, neuroscience was captivated by the Triune Brain theory, which delineated three critical brain regions: the instinct-driven reptilian brain, the emotion-processing limbic system, and the rational-thinking neocortex. Around the same time, the modern Enneagram was being shaped by the insights of psychiatrist Claudio Naranjo in the 1970s. Considering Naranjo's background, it's undeniable that the formation of the modern Enneagram was influenced by contemporary neuroscience. The foundational concepts from both fields mirror each other closely — each initially segmenting the human experience into three distinct arenas.
What captivates me most is the evolution these disciplines have undergone in recent decades. Initially, both fields presented a fragmented view of our being, suggesting we could be compartmentalized into categories of thought, emotion, and instinct. In the realm of the Enneagram, this led to an overemphasis on identifying with a primary center, sometimes at the expense of recognizing our whole selves. Enthusiasts and practitioners alike have often focused on our dominant type and center as if they were isolated from the rest of our personality matrix.
However, as our understanding has deepened since the 60s and 70s, our perspective has broadened. Neuroscience now highlights the brain's remarkable plasticity and the intricate web of connections that underpin our cognitive, emotional, and instinctual lives. Similarly, a shift is occurring within the Enneagram community.
Leading Enneagram teachers and scholars are moving beyond rigid type identifications towards embracing a more dynamic interplay of traits from all nine types and the integration of the three centers. This shift towards a more fluid understanding of personality and brain function is not only fascinating but also vital for our growth and development. I have explored these concepts through my direct experiences in my book, and I am not alone in advocating for this evolved approach to the Enneagram.

Foundations and Traditional Models
In this article, I aim to illuminate the side of the Enneagram that is influenced by neuroscience and indeed following a similar process of evolution. The Enneagram is a reflection and tangent of neuroscience in so many ways, and there are many mirrors. To keep it digestible, in this article, I will highlight the evolution of one theory of neuroscience to demonstrate this parallel — the Triune Brain theory.
The Triune Brain Theory
Developed by Paul D. MacLean in the 1960s, the Triune Brain theory presented an evolutionary perspective on the structure of the human brain. It proposed that the brain consists of three distinct layers that evolved sequentially:
The Reptilian Brain or the basal ganglia, is the oldest layer, responsible for our most primitive instincts such as aggression, dominance, and territoriality. It governs automatic functions and survival mechanisms.
The Limbic System, which emerged with the first mammals, is the center of emotion, memory, and social bonding. It plays a crucial role in forming emotional responses and memories, contributing significantly to our behavior.
The Neocortex, the most recent development in evolutionary terms, is responsible for higher-order thinking skills, including reasoning, abstract thought, and the capacity for language and consciousness.
This model suggested a hierarchical organization of brain functions, from the most basic survival instincts to complex cognitive processes.
The Enneagram's Three Centers
Parallel to the Triune Brain theory in neuroscience, the Enneagram divides the human psyche into three primary centers of intelligence:
The Gut Center (Types 8, 9, and 1), associated with instinct and intuition, mirrors the reptilian brain's focus on survival and instinctual behavior.
The Heart Center (Types 2, 3, and 4), focused on emotions and relationships, reflects the limbic system's role in emotional processing and social connections.
The Head Center (Types 5, 6, and 7), concerned with thinking and planning, corresponds to the neocortex's capabilities for reasoning and abstract thought.
In the Enneagram, each type within these centers processes information and interacts with the world in ways that reflect these primary modes of operation: instinctually, emotionally, or intellectually.
Shifts Towards Integration and Interconnectedness
Neuroscience: Embracing the Brain's Plasticity
Recent decades have seen a paradigm shift in neuroscience, moving away from the static models of the Triune Brain theory towards a recognition of the brain's remarkable plasticity and interconnectedness. This shift is grounded in a wealth of research that underscores the brain's ability to reorganize and adapt throughout an individual's life.
Key Developments:
Neuroplasticity: The discovery that neural connections can form, strengthen, or weaken in response to experience challenges the notion of fixed neural pathways. This underscores the brain's capacity for change and adaptation, significantly impacting our understanding of learning, memory, and recovery from injury.
Neural Networks: Advanced imaging techniques have revealed the brain as a dynamic network of interconnected regions that collaborate across traditional boundaries. This understanding highlights the integrated nature of cognitive, emotional, and instinctual processes, suggesting that no single part of the brain can be solely responsible for complex behaviors or thoughts.
Epigenetics and the Environment: Studies in epigenetics have shown how environmental factors can influence gene expression, affecting brain development and functioning. This research emphasizes the interplay between biology and experience, further illustrating the brain's adaptability.
The Enneagram: From Fixed Types to Dynamic Systems
Parallel to the developments in neuroscience, the Enneagram community has been experiencing its own shift towards a more integrated and dynamic understanding of personality. This evolution moves beyond the rigid categorization into nine types, encouraging a holistic view of personality that recognizes the fluid interaction between all types and centers.
Key Shifts:
Beyond Primary Types: Increasingly, Enneagram teachings emphasize that while we may have a dominant type, our personalities are not confined to a single way of being. This reflects a broader understanding that we embody aspects of all nine types, enabling a more nuanced approach to personal growth and self-awareness.
Integration of Centers: There's a growing focus on the importance of integrating the three centers of intelligence (head, heart, and gut) for emotional balance and psychological well-being. This approach aligns with the interconnectedness seen in modern neuroscience, advocating for a balanced engagement of cognitive, emotional, and instinctual faculties.
Interconnectedness of Types: Advanced Enneagram teachings explore the dynamic interactions between types, including the paths of integration and disintegration, wings, and subtypes. This complex web of relationships mirrors the brain's networked nature, highlighting the Enneagram as a system of interconnected pathways rather than isolated points.
Conclusion
Both neuroscience and the Enneagram are charting courses towards understanding the human condition through lenses of integration and interconnectedness. Neuroscience's insights into the brain's plasticity and networked functioning provide a scientific foundation for the Enneagram's evolving teachings on the dynamic interplay of personality traits and centers. As we continue to explore these parallel evolutions, the synthesis of insights from both fields promises to deepen our understanding of the self, offering richer paths towards personal development and psychological well-being.
Please Note
I approach this topic as an enthusiast rather than a neuroscientist. This exploration comes from a place of passion and curiosity, as an aficionado seeking to understand the dance between the Enneagram and it’s scientific roots. In crafting this article, I drew from a range of sources. While I've strived for accuracy and depth, I encourage readers to delve into the scientific research and Enneagram teachings directly for a more comprehensive exploration.
