In my last post, I came up with an incredibly loose theory of how one might connect MBTI to their astrological birth chart. In other words, can we look at someone’s birth chart and know what their MBTI (Myers-Briggs Type Indicator) might be? It was a fun post, but not based on any stats, only looking at my own birth chart and that of my spouse’s. But it did get me thinking that there doesn’t seem to be much for meaningful data connecting astrology and MBTI.
I have since started collecting charts from various people across astrology/MBTI community boards to try to find tangible evidence of patterns. I am still in the data collection stage and likely will be for quite a while, so my findings will have to evolve and adjust to that over time. So far, the results are promising. As I’ve collected samples almost exclusively from intuitive types so far (those with N for their 2nd letter in their MBTI 4 letter code), I would like to start with what correlations in birth charts might show an intuitive type. I would love to get some charts of sensor types (those with S for their 2nd letter in their MBTI) to compare these against! So far, I have only 1 known sensor chart to work with.
As far as what it even means to have “N” in your 4 letter MBTI, these types tend to focus more on future possibilities/outcomes that “S” types, who are more interested in the here and now. There’s more to it than that, but for the sake of brevity that’s the very generalized difference between these two groups of people. The N function deals more in abstracts and theories, while the S function deals more in observational data. All types use some degree of N, but the ones who are “N” types are considered “high N,” meaning they use it as either their dominant function or their auxiliary function in their 4 main functions.
Which planets show up as Intuition in the birth chart?
My immediate intuition on what planets/placements would most likely be involved with high N users would say Uranus and Neptune. Uranus is very forward/future thinking, seeing many different possibilities, while Neptune is considered perhaps the most intuitive planet by its very nature, pulling energy deep from the collective unconscious. By that same token, placements involving the planets these 2 planets rule (Aquarius and Pisces) should also be factored in, as well as the 12th house, natural home of Pisces and dealing with similar themes. I was hesitant to include the 11th house in the considerations for intuitives, as it seems to deal more with extroverted energy in general than intuitive energy (being the house of groups/communities/friendships).
I also believe that Uranus and/or Neptune conjunct a chart angle, such as Ascendant, Descendant, Midheaven, or Imum Coeli, should also be counted as significant placements for these 2 planets when determining strong N, as well as either planet in the 1st house (house of self) or 12th house (house of collective unconscious, though I believe 12th house is more associated with introverted intuition “Ni” than extroverted intuition “Ne”).
I should note that N types are considered a minority in the overall population, and so having some rather narrow constraints like this seems to make sense to me at this stage in my research.
Again, I’m working with a very small sample size to start here and so these findings are nowhere near conclusive. If you would like to participate in this study by providing your birth chart and MBTI, I would greatly appreciate the data! You can email me at email@example.com with your birth chart (or just send birth date, time of birth, and location of birth, if you are comfortable doing so). If you just send a birth chart, feel free to crop out the birth data if you would like. You do not need to use your real name, of course. Please include your MBTI.
Aspects to Neptune
So far, I only have 23 charts to work with. Of these, 22 are from N types. Mainly I have collected samples from ENTPs, with 13 ENTP charts, 5 INFJ charts, 3 INFP charts, and 1 INTP chart. Of those 22, 95% of them have at least one aspect from their Neptune to a personal planet (Sun, Moon, Mercury, Venus, or Mars). 57% have 2 or more Neptune/personal planet aspects. (I will address the 1 chart that had no major Neptune aspects in the next section.)
Of those aspects, the most frequent Neptune/inner planet combination is Mars in aspect to Neptune (occuring 11 times), then Venus/Neptune (8 times), Moon/Neptune (7 times), Mercury/Neptune (5 times), and least common planet combination being Sun/Neptune (4 times). Five charts had Neptune in the 1st house, four had Neptune conjunct a chart angle, and ten had Neptune in any major aspect to an angle.
Is it Ni or Ne? Introverted vs. Extroverted Intuition
If Neptune aspects do in fact contribute to strong intuitive tendencies in a birth chart, which connecting planets would correlate with introverted/extroverted intuition, and by which aspects? Looking at which inner planets/luminaries are astrologically associated with extroversion, let’s start with the Sun and Mars (masculine/extrovert/yang energy). In 91% of the charts with Mars/Neptune aspects, the associated MBTI uses Ne, extroverted intuition. In 75% of the charts with Sun/Neptune aspects, the associated MBTI uses Ne.
Of the 16 Ne users I’ve sampled, 25% have no aspects between either Sun/Neptune or Mars/Neptune. However, one of them (an INFP) has a Mercury/Neptune conjunction in their 11th house, which is all about group, collective, multiples, house of Aquarius, an extroverted house, opposing their Moon. The 2nd one, another INFP, has Mars (extroverted planet) sextile Uranus (intuition). Uranus is especially strong in this person’s chart being conjunct their IC angle. The 3rd, (ENTP) has Mercury in the 1st house (an extroverted house, natural house of Aries) opposite Uranus, the other intuitive planet I’ll discuss more later. I found a Mercury/Uranus aspect in 9 of 16 Ne users, or 56%. And the 4th chart of a Ne user with no Sun or Mars to Neptune aspects, again has Mercury in aspect to Uranus, with Mercury in an extrovert house (5th house, natural house of Leo), in the extrovert sign Gemini, and also has their Sun (extroverted energy) in aspect to Uranus (intuitive energy).
As for the Ni users, my sample size is even more limited so far, but using the rule of Sun/Mars to Neptune for extroverted intuition, it follows that Moon/Venus to Neptune would be introverted intuition. However, in only 2 of the 4 Ni-dominant charts does this prove to be the case, with a Venus/Neptune trine aspect and a Moon/Neptune trine aspect in one chart, and Venus quintile Neptune in the 2nd chart. The 3rd INFJ has only a “Ne” Neptune aspect, and the 4th has no Neptune aspects at all! UPDATE: After publishing this post and collecting more samples of Ni users, there does not appear to be a higher correlation of Neptune aspects to feminine planets vs. masculine planets.
With that said, what other factors might correlate with Ni in their charts? Let’s look at them one at a time. The first one has only 1 Neptune aspect, Sun sextile Neptune. Their Sun is in Scorpio, a water sign (feminine/intorvert/yin), where the Ne users with Sun/Neptune typically had more extroverted Suns, like Sagittarius and Gemini, or their Sun in the 5th house (extroverted house) trine their Ascendant (the outward personality).
What about the other INFJ chart that has no aspects to natal Neptune? They still have a prominently placed Neptune, in their 1st house, house of self. They also have Mercury (the mind) in the mystical 12th house (as mentioned earlier, this is an introvert house, natural house of Pisces, and I would more likely associate it with Ni over Ne). They also have a 12th house Sun, which again shows a tendency towards introversion. This INFJ also has some Aquarius energy happening for them, with Moon in Aquarius and Uranus conjunct the Ascendant. Which brings me to the 2nd planet in consideration….
Aspects to Uranus
Of my 22 N type participants, 81% have at least 1 aspect between their Uranus and one of their personal planets or conjunct an angle. 54% of total N types have at least 2 aspects between Uranus and a personal planet or conjunct an angle. And of all 21 samples, 72% have both Uranus and Neptune aspects in their chart.
Of those, the most frequent Uranus/inner planet combination is Mercury in aspect to Uranus, occurring 11 times. Interestingly, this occurs exclusively in Ne user samples. The second most common frequent combination is a tie between Mars/Uranus and Venus/Uranus (6 times each), and then Sun/Uranus (5 times). Moon/Uranus was the least frequent occurrence overall, at 4 times. Two charts had Uranus in the first house, six charts had Uranus conjunct an angle, and 18 charts had Uranus in any major aspect to an angle.
Ni or Ne and Uranus aspects
Again, we’ll visit the idea of Sun and Mars in aspect to Uranus for Ne, and Moon and Venus in aspect to Uranus for Ni. The results are fairly consistent again, with Sun and/or Mars aspects to Uranus occurring almost exclusively in Ne users, with the exception of 1 INFJ chart that has a Mars/Uranus square. However, this chart also has Moon (introverted/feminine/yin energy) square Uranus (intuition), as well as Venus sextile Uranus, meaning there are more “Ni” Uranus aspects than “Ne” ones.
Another INFJ has Venus trine Uranus, and the other 2 have no Uranus/planet aspects at all, though 1 has Uranus conjunct the Ascendant and the other has Uranus in the 1st house.
UPDATE: After publishing this post and collecting more samples of Ni users, there does not appear to be a higher correlation of Uranus aspects to feminine planets vs. masculine planets.
However, perhaps the strongest indicator so far of Ne in regard to Uranus is the frequent Mercury/Uranus combination, which does fall in line with planetary archetypes, as Mercury represents the lower mind and collecting information, while Uranus represents the higher mind and forward projection, thinking of all future possible outcomes.
Pisces and 12th house Placements
I was also curious to see whether there is any correlation between Pisces or 12th house placements in the birth chart and N-types. The results here are much weaker, with only 47% of the total sample showing any Pisces personal planets, basically chance. Of those, Pisces Moon has a slightly higher occurrence frequency at 4 times, with Mars in second at 3 times, and the Sun only twice. Mercury Pisces was present in just one chart. I suspect Pisces placements have little to do with whether one is N-type or not, though of course all findings are still inconclusive.
Of 12th house placements, this wasn’t much better, with only a 52% occurrence of any planets showing up in the 12th house across all samples.
Aquarius and 11th house Placements
The results for Aquarius placements and intuitive types are even weaker than the Pisces results, with only 28% of the total sample showing any Aquarius personal planets. Of those, the Moon again has a very slight lead at 3 occurrences, with Sun, Ascendant, and Venus each occurring twice, and Mercury and Mars occurring once each.
11th house placements came out about the same as 12th house placements, at a 47% occurrence of any planets showing up in the 11th house across all samples.
While this study is nowhere near complete, even in regard to what would correlate with N-types of the MBTIs, it does appear that so far, there is a correlation between strong Uranus/Neptune in the chart with intuitive types. There does not appear to be a correlation between Pisces/Aquarius or 12th house/11th house placements in the chart with intuitive types.
In my next installment of this series, I’ll be writing about another cognitive function and how it might correlate in birth charts. I definitely need more birth charts for this study, so if you would like to contribute, please reach out to me at firstname.lastname@example.org!
