The Eight Neojungian Functions


People assume that the cognitive functions are a strict hierarchical system of opposing cognitive functions, but *actually* from a pluralistic, non-linear viewpoint – it’s more like a big ball of wibbly wobbly – cogny – funky stuff.

Doctor Who references aside, what I want you to realize is that the cognitive functions are more often than not working in tandem with one another, like wheels, spinning faster and faster, the more intense and chaotic the situation you are in. Recognizing the individual functions is easier when you are alone introspecting, and harder to tell apart when you are interacting with others. The cognitive functions in Neojungian Typology are based on cooperating networks that can work simultaneously. Neojungian Typology further believes that the functions are activated by chemical responses – dopamine, serotonin, oxytocin and endorphine levels in the brain.

What’s proven?

  • The networks we base this on are real and highly relevant to Jungs cognitive functions.
  • It’s been proven that neurotransmitters drive much of our brain activity and which networks we use.
  • It’s confirmed that networks can cooperate to form things similar to the Jungian cognitive functions.
  • How and which neurotransmitters drive each function is yet to be known.

Introverted Intuition (Ni) – Top-down proactive frontopolar network

Introverted Intuitives are cautious to new ideas but once they have gotten interested, they think long and hard about it, considering it from a long-term, nuanced perspective. IN*Js think creatively and independently from the people around them. They are good at filtering out environmental input and organizing their creative output. They benefit alot from exercises that enhance their focus, clarity, and creativity. Ni is a top-down, anticipative process, and it’s about bringing insight from the inside out into the world. Introverted Intuition is about anticipating and preparing for the unexpected, foreseeing what nobody else sees coming, guessing what’s most likely to change in the future.

Ni is the most active when dopamine is high in the frontopolar network but low in the saliency network. Low dopamine in the saliency network can drive a strong sensitivity to sensations. (HSP)

Extroverted Intuition (Ne) – Bottom-Up Reactive Frontopolar network

EN*Ps tend to lack caution and tend to easily engage in creative thinking together with the people in their environment. They find it easy to get excited about something new, but can also lose interest in it quickly. They associate freely and can quickly consider multiple viewpoints individually. They tend to have most ideas while studying and scanning their environment. Extroverted Intuition is a bottom-up process – it starts on the outside and is often about bringing ideas you find around you to the inside – solving problems you are having by working together with others.

Ne is the most active when serotonin is high in the frontopolar network but low in the saliency network. Low serotonin in the saliency network can drive a strong fear of being tied down or controlled.

Extroverted Feeling (Fe) – Bottom-up proactive default-mode network

Extroverted Feeling makes an E*FJ more receptive to social feedback and more socially adaptable. E*FJs quickly mirror and adapt their behavior to the group and show a high ability to push for and build interest for their opinions and causes. E*FJs with extroverted feeling are highly proactive about causes and social issues. Extroverted Feeling is a bottom-up process, so it starts on the outside, with how others are feeling and how things outside you look, sound, and feel, bringing what you experience inside and making it a part of your inner world.

Fe is the most active when oxytocin is high in the default-mode network but low in the task-positive network. Low task-positive oxytocin can trigger a feeling that you are bad or too weak to engage in work or physical exercise.

Introverted Feeling (Fi) – Top-down reactive default-mode network

Introverted Feeling (I*FP) works as a top-down, reactive process: it filters and analyzes and studies it’s own experiences, feelings, and values, questioning what it feels, what it wants, and what it experiences. It is a social-evaluative process: it questions your empathy, your goodness, the honor in your desires and wants. It tests that your intentions are pure and that you are being authentic. It thinks independently, on it’s own, about the nature of goodness, rather than consulting and involving the group in the process.

Fi is the most active when endorphines are low in the task-positive network network but high in the default-mode network. The low endorphines in the task-positive network can drive a sensitivity to pain and to physical harm.

Introverted Thinking (Ti) – Top-down reactive task-positive network

Introverted Thinking (I*TP) is triggered by work, physical issues or issues in your body or in your efficiency. It asks you if you are strong enough, tough enough, fast enough, smart enough. It questions your abilities and your ability to deliver according to people’s expectations. It makes sure you have enough energy and resources to complete what you have set out to do. Introverted Thinking is a performance-evaluative process. It works from the inside, without involving the group in the analytical process, thinking up methods to improve and solutions to ensure you can be as efficient as possible with your resources.

Ti is the most active when oxytocin is low in the default-mode networks but high in the task-positive network. It drives us to study, better ourselves, and improve problems on our own to gain the groups admiration and respect. The low DMN oxytocin drives often a feeling of strong shame and a feeling of not being good enough in the group.

Extroverted Thinking (Te) – Bottom-Up proactive Task-positive network

Extroverted Thinking (E*TJ) is triggered by work, physical exercise, and immidiate physical issues and tasks that need to be completed. It asks you to work together with the group to fix and deal with a problem in your environment. It drives you to respond to challenges and obstacles in your immidiate environment or to find solutions to problems together with the group or in a manual. Extroverted thinking is a performance-proactive process, it drives you to tackle issues ahead of time, it collaborates with and relies on tools in your environment to solve problems.

Te is the most active when endorphines in the task-positive network are high. It drives you to feel strong, invulnerable, powerful, and forceful. Endorphines are low in the default-mode network, which can trigger strong emotional pains and negative social reactions.

Extroverted Sensing (Se) – Bottom-up reactive saliency network

The saliency network is mostly triggered by strong stimuli and intense environmental input, for example visceral, strong colors, loud noises, strong smells. Extroverted Sensing (ES*Ps) is activated by immediate environmental input, such as nearby ambulances passing by, or strong sensory input in your nearby environment. Extroverted Sensing is bottom-up and reactive and highly – and quickly – responsive to suggestions and input from people around them. It’s an adaptive function, and does not anticipate, but has strong and quick reactions.

Se is the most active when dopamine is high in the saliency network. It drives hunger, physical cravings, and need for sensory stimulation. Dopamine is low however in the frontopolar network, and that can trigger strong frustration or anger towards the unknown.

Introverted Sensing (Si) – Top-down proactive saliency network

Introverted Sensing (IS*Js) anticipates events to come – actions that should occur around this time, or in this situation. It prepares you mentally and tries to accurately remember when and how an event went down for future learning. Introverted Sensing focuses on remembering stronger experiences, loud noises, strong smells, and explicit images in more exact detail. Introverted Sensing is a visual-sensory process, it’s main priority is to not be caught off guard by anything unexpected or dangerous, and to keep you safe and prepared.

Si is the most active when serotonin is high in the saliency network. It drives calm, order, organization, and preparatory behavior. Serotonin is low in the frontopolar network however, which can drive erratic, chaotic responses to unanticipated events.
