If you have worked with Bowen’s family systems theory, you may have noticed that some of its core concepts pull in different directions. These tensions are not errors — they reflect genuine complexity in the theory. Active Inference, a framework from contemporary neuroscience, offers a way to revisit these tensions through one of its foundational concepts — the triangle.
Tensions in Bowen’s Triangle
- Bowen’s theory presents differentiation of self and chronic anxiety as two distinct variables — the main variables of the theory — yet treats them as correlated: as one increases, the other decreases. Are there one or two variables in the triangle dynamics?
- Bowen’s theory holds that the more individuality force, the better — yet it also presents the optimal state as a balance between the life forces of individuality and togetherness ”neither force overriding the other” (Bowen 1974). These arguments are valid in the contexts where they are used, but seem logically contradicting each other. How do you reconcile them?
- The level of differentiation is, according to Bowen theory, largely stable across an adult lifetime and emotional functioning is essentially instinctual — yet the entire clinical approach assumes that people can consciously develop their differentiation. How can one actually work on differentiation given those constraints?
The Reconstruction in Brief
The following readings address the three tensions outlined above and are expressed in the language of Bowen theory. Their meaning, however, reflects a formal reconstruction of the triangle — one that draws on a contemporary Active Inference framework to clarify the logical structure of Bowen’s original ideas. A logically consistent theory can, in principle, be given a formal expression. This, however, does not call for measurement or calculation in practice — a position Bowen himself held.
This interpretation of the triangle emphasizes two structural features of human functioning: the temporal distinction between long-term development and short-term adaptation, and the predictive — rather than reactive — nature of behavior.
- Differentiation of self and chronic anxiety are the two main variables of Bowen theory — and they are formal complements: as one increases, the other decreases. This complementarity reflects the fact that they are not truly independent constructs, but two expressions of a single underlying variable. Their difference lies in location and function: differentiation of self is located within the individual and refers to how accurately they observe their environment, while chronic anxiety is located within the family system and refers to how flexibly the individuals respond to their environment. Together they describe two sides of the same process — one shaping perception, the other driving behavior. Seen this way, the apparent contradiction dissolves: Bowen’s theory does not present two separate variables, but one variable expressed as two complementary aspects of a single process.
- The apparent contradiction between ”more individuality is better” and ”balance is optimal” dissolves once we recognize that the life forces operate on two distinct dimensions. The vertical dimension concerns the individual’s development: as a subsystem differentiating from the parent system, more individuality means greater autonomy and a more developed self. The horizontal dimension concerns functioning within the relationship system: here, the optimal state is a dynamic balance between the two forces — neither overriding the other. Bowen illustrates this with a 50-50 balance, but the point is not rigid equality; it is that an excess of either force leads to over- or underadaptation in the relationship system. Bowen’s arguments are not contradictory — they are valid in their respective contexts. The confusion arises when the two dimensions are collapsed into one.
Collapsing the two dimensions turns differentiation of self and the individuality force into synonyms — as Kerr (2019) has noted — but their relationship is more precise: differentiation is a variable that shapes how the individuality force operates in the relationship system (vertically or horizontally), while the life forces in turn influence both moment-to-moment adaptation and the development of differentiation over time. - In principle, between stimulus and response there is a moment where the individual is supposed to either follow the automatic emotional response or engage a more deliberate process. Yet this formulation conceals a tension: if emotional functioning is instinctual and non-conscious, the moment between stimulus and response — emotional reaction — is by definition not at individual’s control, as Bowen theory implies.
Active Inference reframes this tension. Differentiation of self, in this reading, reflects how the individual responds when an external perturbation reduces the precision of the fast policy (emotional reaction). The perturbation creates the opening — it is the relational system that either stabilises or destabilises the automatic response — but whether a slower, higher-level policy can step in depends on the agent’s internal capacity to sustain the uncertainty long enough for a more viable course of action to emerge. Both aspects of the main variable are necessary: the relational system creates the conditions (external aspect), and differentiation of self (internal aspect) determines what becomes of them.
Explore the concepts interactively
To demonstrate the reconstructed concepts of the triangle, the following interactive tool visualizes the relationships between differentiation and the vertical and horizontal dimensions of the life forces — for one agent only, not the triangle as a whole. Feel free to play with the variables. The tool opens in a new window; use the instructions below to read the visualization.
Instructions for the interactive tool
- The vertical axis represents differentiation of self as an internal variable — the higher the position, the more accurately (objectively, in Bowen’s terms) the agent observes their environment. The range of differentiation is set by the family of origin using the first slider.
- The horizontal axis represents the balance of the life forces in the relationship system in momentary adaptation to others. The center is the optimal state. Movement toward either end indicates a bias driven by chronic anxiety — toward excessive togetherness on the left (over-adaptation), or excessive individuality on the right (under-adaptation). Deviation from the optimal state corresponds to the concept of pseudo-self, and the bias runs in either the functional self direction (excessive individuality) or the functional no-self direction (excessive togetherness).
- The diagonal line connects the two dimensions: as differentiation increases, the individuality force — understood as trusting one’s internal model of beliefs — grows, reflecting a long-term or developmental view of individuality.
- The gray dot on the vertical axis shows the current level of differentiation. The dashed lines show how this level sets the deviation zone on the horizontal axis. The green markers show the amount of chronic anxiety pushing the agent to over- or under-adapt. The red segment on the vertical axis shows the degree of internal chronic anxiety — the complement of differentiation within the agent. The red line on the horizontal axis shows the degree of external chronic anxiety — the pressure coming from the chronic anxiety-driven behavior of others in the relationship system.
Agency Triad
Triangle is the name Murray Bowen gave to a foundational concept in his family systems theory. The agency Triad is a reconstruction of that concept — not a replacement, but a formal interpretation of what the triangle describes and how its core concepts relate to each other.
The term ”Agency Triad” is deliberate. Active Inference, the contemporary framework informing this reconstruction of Bowen’s triangle, is precisely a theory of agency. Kerr (2019) also refers to having a self as having agency — a connection that points toward the central process of the triangle. From the perspective of research on professional agency, dimensions of agency align naturally with the dynamics the triangle describes.
The ”Agency Triad” acknowledges the distance from the traditional interpretation of Bowen’s triangle while recognizing the debt to Bowen’s foundational work — this reconstruction is a reinterpretation, not a revision.
About Petri Ruotsalainen
My encounter with Bowen’s triangle goes back to the late 1990s, when I studied theology at Baylor University in Texas and read Generation to Generation by Edwin H. Friedman. The triangle later became the foundation of my work as a trainer and consultant when I started my own practice in 2001, focusing on leadership and collaboration. In other words, the three agents, two life forces and one variable, differentiation of self, have been both the focus and lens of understanding Bowen theory over 25 years.
In 2022–2023 I completed the Postgraduate Program in Bowen Family Systems Theory and Its Applications at the Bowen Center. I am currently completing a doctoral dissertation at the University of Jyväskylä, Faculty of Education and Psychology, where I study professional agency — particularly its embodied and emotional dimensions — alongside my practice. A central part of my research is theoretical: in collaboration with the Faculty of Information Technology, I have been developing a mathematical formalization of Bowen’s triangle.
Knowing and Becoming
Bowen’s theory is sometimes read as a warning against shared thinking — as if dialogue itself were a form of fusion. I take a different view. Humans survive as a group; learning and development happen naturally in collaboration. Working toward differentiation does not require avoiding reasoned argumentation or shared reflection. On the contrary: dialogue — the exchange of thinking based on one’s observations of relationships — is a laboratory for noticing fusion and practicing differentiation, much as engagement with one’s family of origin is the natural ground for strengthening it.
Theory as propositional knowledge needs to become embodied — lived rather than merely known. As the Kantian dictum goes: ”Theory without empirical data is empty; empirical data without theory is blind.” Yet theory sharpens observation, and dialogue is a way to deepen its understanding.
My practice focuses on leadership and collaboration development within the framework of professional agency — the agency triad being a central tool. If you are looking for professional support, I offer online coaching and consultation.
