What Your Brain Activity Reveals About Your Personality Type
Explore Dario Nardi's EEG research to understand how brain activity connects with MBTI personality types, revealing insights into behavior and decision-making.
Explore Dario Nardi's EEG research to understand how brain activity connects with MBTI personality types, revealing insights into behavior and decision-making.
Dario Nardi's EEG research reveals a direct link between specific brain activity patterns and MBTI cognitive functions, such as the 'tennis hop' for Extraverted Sensing and a 'zen-like' pattern for Introverted Intuition. Understanding these neurological differences can explain workplace friction arising from diverse processing styles and offers practical strategies like using visual aids or requesting processing time to improve communication and collaboration.
Ask a Jungian analyst about cognitive functions, and you'll hear about 'psychic energy flowing through archetypal channels.' Ask a neuroscientist, and they'll tell you there's no evidence functions exist. The truth, as usual, annoys both sides, leaving a fascinating gap between subjective experience and objective science.
Lisa’s stomach tightened. Ten minutes into the brainstorming session, her colleagues were firing off ideas like a pinball machine. She had a good one—a great one, even—but the thought of breaking into their rhythm made her throat close up.
As the discussion heated up, Lisa felt her mind racing. Instead of articulating her thoughts, she felt like an outsider, overwhelmed by the rapid-fire suggestions. This wasn’t a new feeling; it was a recurring source of anxiety in her work life.
After several weeks of this turmoil, Lisa attended a workshop where Dr. Dario Nardi was presenting his findings on the neuroscience of personality. Intrigued by his EEG research, she learned how different personality types show different brain patterns. This sparked her curiosity about the cognitive functions at play in her own experiences.

In his 2011 book, 'Neuroscience of Personality,' Dario Nardi's EEG studies on 60 participants found that cognitive functions manifest through specific brain patterns. For instance, extraverted sensing (Se) types, such as ESFPs, display what Nardi calls a 'tennis hop' brain pattern. This is characterized by low amplitude and out-of-sync activity across the neocortex, which helps them adapt rapidly to new tasks.
Conversely, introverted intuition (Ni) types like Lisa exhibit a 'whole-brain, zen-like pattern.' This involves synchronized, medium-low frequency, high-amplitude brain waves, especially when they envision future possibilities. It’s a stark contrast that can make Lisa feel overwhelmed in chaotic environments.
Understanding these differences can help Lisa make sense of her struggles. While her colleagues thrive in chaotic environments, her preference for deeper, more introspective thought processes may lead her to feel sidelined in fast-paced discussions.
The friction in Lisa's case stems from a clash of cognitive styles. Dominant judging types, like her colleague who leads discussions, may activate the left prefrontal cortex, focusing on analysis and decision-making. Meanwhile, perceiving types, including Lisa, often engage the right prefrontal cortex, which favors exploration and flexibility.
This difference in how their brains are wired creates tension. Lisa's need to process ideas at her own pace clashes with her team’s demand for quick responses. A 2015 study in the Journal of Applied Psychology found that these opposing patterns can lead to misunderstandings, leaving Lisa feeling sidelined while her colleagues perceive her as disengaged.
After attending Nardi's workshop, Lisa began trying a few new tactics to bridge the gap between her cognitive style and that of her team. For instance, she started preparing visual aids for meetings—something that Nardi suggests can optimize communication for introverted types. This approach allowed her to express her ideas more clearly and engage her colleagues effectively.
Additionally, she initiated one-on-one check-ins with her teammates to discuss feedback outside the pressure of group dynamics. This provided a space for her to articulate her thoughts without the chaos of a larger meeting. Gradually, she noticed her confidence growing as her colleagues began to appreciate her unique insights.
Lisa's journey shows a few key lessons for anyone handling different personalities in a professional setting. Understanding cognitive functions can illuminate why certain situations feel challenging.

The part about introverted intuition types having a 'whole-brain, zen-like pattern' but feeling overwhelmed in chaotic environments... does this mean INFPs will always struggle in quick brainstorming sessions? I just got typed and I'm a bit nervous about feeling sidelined forever.
Okay, so the 'What Actually Helped' section is gold. I'm going to try those visual aids for meetings and schedule some one-on-ones. And that 'Can we pause for 10 seconds?' phrase? Definitely using that next week to manage rapid-fire discussions.
This article perfectly describes my experience in group projects. I remember one time, everyone was just throwing ideas around, and I had this really developed, holistic solution forming, but it felt impossible to articulate it in the moment. My brain felt like it needed to connect all the dots first, like that 'whole-brain, zen-like pattern' mentioned for Ni types. It's like my dominant judging colleagues activate their left prefrontal cortex for quick analysis, while my right side is still exploring. I often feel like I'm watching a fast-paced tennis match, unable to jump in, and end up feeling sidelined and disengaged, just like the study mentioned.
