Practitioners working with cognitive processes often describe them as standalone elements. “That is their Se showing up.” “She leads with Fe.” “He needs to develop his Ne.” This language treats the eight cognitive processes as independent instruments that can be identified, described, and developed one at a time.
Read through the lens of entangled pairs, the pattern reveals something different. The eight processes appear to organize into four structural pairs: Se/Ni, Si/Ne, Te/Fi, and Ti/Fe, which show up as the dominant and inferior and the auxiliary and tertiary within each type. These pairs are entangled, meaning that when one process in a pair occupies a position in the hierarchy, its partner tends to occupy the opposite position. They appear less like two independent processes that happen to coexist and more like one dynamic observed from two perspectives.
This means you cannot accurately point to a behavior and call it “Se” or “Fe” as if a single process produced it. An ENTJ leader who wants to develop greater empathy in how they relate to others is engaging the full cognitive process pattern, not a single process. Their dominant Te is entangled with inferior Fi. Understanding this, the practitioner can guide the development conversation to work with that connection rather than treating empathy as a skill that can be strengthened in isolation. The entangled structure changes how practitioners can teach clients about what they observe in terms of which cognitive processes may be in play.
The four entangled pairs
- Se/Ni — engaging with what’s real now, synthesizing meaning and future vision
- Ne/Si — exploring possibilities and connections, drawing on what’s proven
- Te/Fi — organizing for results, staying true to personal values
- Fe/Ti — building relationships and group harmony, refining ideas for precision
How the entangled pairs structure the type pattern
Through their dominant process, Introverted Intuiting, INTJs possess a deep ability to recognize patterns and uncover underlying principles in complex systems, enabling strategic decision-making. Through their auxiliary, Extraverted Thinking, they organize their external world to achieve practical goals. Notice how the entangled pairs structure the full pattern: Ni/Se spans dominant to inferior, and Te/Fi spans auxiliary to tertiary. The pairs are locked across the hierarchy, which is why the whole pattern moves as a system.
Through their dominant process, Extraverted Feeling (Building Relationships and Group Harmony), ESFJs are naturally attuned to others’ emotions and needs, working to ensure everyone feels heard and valued. Through their auxiliary, Introverted Sensing (Drawing on What’s Proven), they recall past experiences and uphold traditions to inform their decisions. Again: Fe/Ti spans dominant to inferior, and Si/Ne spans auxiliary to tertiary. Different pattern, same structural principle.
Why the processes seem entangled
The entangled processes framework treats each of the four function-attitude pairings (Se/Ni, Si/Ne, Te/Fi, Ti/Fe) as a single dynamic expressed in two orientations, rather than as two processes working in cooperation. This framing builds on Jung’s compensation principle and the longer tradition of recognizing structural relationships among the cognitive processes within psychological type.
A parallel from quantum physics helps illustrate the relationship between these processes. Entangled particles are fundamentally linked so that the state of one defines the state of the other. They are not two separate systems that happen to interact, but one system observed from two orientations. The cognitive process pairs seem to work in the same way. Se and Ni are one perceptual dynamic expressed in two directions, instead of two separate processes.
Why you cannot describe one process without its partner
For example, let’s look at the interconnection between Se and Ni. Four types have this pair in their type pattern with Ni in the dominant or auxiliary position: INTJ, INFJ, ENTJ, ENFJ. Four other types either lead with Se or have it in the auxiliary position: ESTP, ESFP, ISTP, ISFP. Same entangled pair, eight different cognitive process patterns, eight different expressions.
INTJs’ inferior process, Extraverted Sensing, provides occasional awareness of the physical environment when they need to bring their abstract vision into concrete reality. When this leader describes where the organization needs to go, they are envisioning a concrete future state. That vision is not “just Ni.” This appears as Se/Ni working as a single dynamic: the capacity to see long-range patterns grounded in an awareness of tangible, real-world conditions, even though the Extraverted Sensing process is less accessible. Through their auxiliary, Extraverted Thinking (Organizing for Results), INTJs organize that vision into a structured plan. The observable pattern is a leader who sees where things are heading and builds the path to get there.
INFJs lead with the same dominant process, Introverted Intuiting, but the dynamic pattern is different. Their auxiliary is Extraverted Feeling (Building Relationships and Group Harmony), not Extraverted Thinking. So when an INFJ perceives the same kind of deep pattern, they communicate it differently. Where the INTJ structures the insight into an execution plan, the INFJ translates the insight through relational and emotional language: allegories, metaphors, and stories that help others feel the meaning of what they have seen. The Ni/Se dynamic appears in both, but its expression is inseparable from the rest of the pattern.
The ISFP’s relationship with Se/Ni is reversed. Their dominant is Introverted Feeling (Staying True to Personal Values), and their auxiliary is Extraverted Sensing (Engaging with What’s Real Now). In the ISFP pattern, Extraverted Sensing sits in the auxiliary position, and Introverted Intuiting sits in the tertiary, so the Se/Ni dynamic plays a supporting role rather than leading. Their auxiliary, Extraverted Sensing, makes ISFPs highly responsive to the sensory details of their environment, showing keen awareness of what is happening around them, with a quieter Introverted Intuiting that occasionally surfaces as subtle insights into the future. Their Se/Ni dynamic is oriented toward present engagement with only occasional long-range depth. That is a fundamentally different expression of the same structural pair.
The entangled pairs provide a framework that helps practitioners and clients see behaviors as expressions of a dynamic system rather than processes working in isolation. When a coach and client can see Fi/Te or Se/Ni as one connected dynamic rather than two separate skills, the development conversation gains depth and specificity.
Without understanding the dynamic, Extraverted Sensing looks like quick action and environmental awareness as if it is operating alone. But in the INTJ, Se looks like grounding an abstract vision in concrete reality. In the ISFP, Se appears as responsive attentiveness to the surroundings, filtered through personal values. In the ESTP, Se looks like rapid tactical engagement analyzed through internal logic. Same process, different levels of accessibility, different judgment pairs, different behavior. The entanglement is what makes the difference visible.
A suggestive pattern from EEG research
Suggestive support comes from EEG research, though the samples are small and the work isn’t yet peer-reviewed. In an early UCLA study of 56 participants, Nardi found that types sharing the same entangled pairs in reversed positions showed the most similar brain activity. ISFP and INTJ, for example, came out as neurological “nearest neighbors” despite looking opposite on the four-letter code. Both carry the same entangled pairs (Fi/Te and Se/Ni), just in reversed positions. This pattern held for ten of the sixteen types in his sample, and Nardi hypothesized it might hold for all sixteen with a larger sample. Independent replication hasn’t yet been published.
What this means for development conversations
A practitioner working with an ENTJ client may notice something the client cannot quite name. A team member’s contribution lands as dismissed, even though the client did not intend it that way. Type dynamics gives the practitioner a way to enter that conversation. The ENTJ’s Te/Fi dynamic operates with Te in the dominant position and Fi in the inferior. In this individual, the dynamic is expressed more strongly through their conscious dominant process and less so through their more unconscious inferior process. A development conversation can engage through this entangled dynamic rather than framing the less conscious side as something missing or separate.
The practitioner who understands the entangled structure can have a conversation with a client about the entire span of cognitive processes within their code. Introverted Feeling can be framed as the least accessible of the first four processes in the type hierarchy. It can be described as the connection between one’s decisions and one’s values. It is harder to grasp from the inside, and harder for others to observe from the outside. The development edge is about expanding awareness to something that is already part of how one operates.
That is a development conversation that works with the system rather than against it.
The practitioner who understands the entangled structure does not isolate processes when describing what they observe. Instead of saying, “that is your Se” as if it is a static process operating independently, they can explain to a client that Se/Ni is one dynamic; Te/Fi is another; and the full type pattern produces the behavior they observe. That precision changes the conversation and helps the client see their own type in a dynamic pattern with more clarity.
