Q&A with Dr. Dario Nardi on Reddit
Dr. Dario Nardi scanned brain activities with EEG and discovered some fundamental diferences between different personalities as described in MBTI and Socionics typology. In this link he answer questions from public.
(…) my research suggests that the second most common pattern is our near-opposite personality type, say ISFP for INTJ. That’s Fi + Se. As I look at the brain activity of midlife adults now in my lab, and not just college students, I see this more than ever. I’ve had two midlife INFJs. Could hardly tell if they are INFJ or ISTP.”
“I describe in “Neuroscience of Personality” a variety of correlations between personality type and frequencies and amplitudes. For example, “solid bright blue” relates to a flow or waiting state, where all regions of the neocortex are dominated by very high amplitude delta waves. Anyone might show this pattern. The link to type is what tasks or events correlate with it. Then there is the “Christmas tree” pattern typical of Ne types. That pattern is high amplitude combined with a range of ever-changing frequencies.”
“With regard to Feeling versus Thinking types, some research about EQ and type (by Roger Pearman?), strongly suggested that Feeling types develop emotional competencies in a particular, steady order that affords decent coverage of all the competences, while Thinking types develop emotional competences to meet environmental demands, often in a haphazard order, and thus can be quite adept in some emotional areas and severely deficient in others.”
“Also, some people show relatively much more activity in the prefrontal regions than other regions, at least in my lab environment. Among these are the dominant extraverted Intuiting types (ENFP and ENTP) along with most introverted types.”
“Regarding general intelligence, I’ve met INFJs with more accurate mental models and effective definitions than their INTP counterparts in the same technical domain. Similarly, I can imagine an ESFP having more effective organizing skills than her ESTJ peer. I’ve seen ENFJs with more effective use of extraverted Sensing than ISTPs in the same domain. There are many possible reasons: — better integration of self and the various functions — an environment that is more appropriate (e.g. INTP alchemist versus ISFP chemist–who does chemistry better?) — different developmental space (or developmental level, if you’re into that)”
“In the EEG, I have never seen an INFJ or INTJ — either college age or among the 3 midlifers — meet the criteria for the “Christmas tree” pattern so common with ENTP and ENFP, and present at times for INTP and INFP. That form of cross-contextual thinking is just not happening in the brain.”
