MBTI in the Birth Chart: ISFP

Chart of an ISFP

Today I’m going to look at the birth chart of an ISFP to see what might correlate with the function stack order of this type (Fi, Se, Ni, Te). Normally I would look first for any planets in essential dignity in the chart (particularly personal planets). There are no planets in domicile or exaltation in her chart, but Venus is in accidental dignity by being in the second house (corresponding with Taurus, the 2nd sign in the zodiac, which is ruled by Venus). Venus also has the most aspects to it of any personal planet (only counting major aspects). So I would say Venus is probably the strongest planet in her chart, and Venus represents one’s values. For ISFP, the dominant cognitive function is Fi (Introverted Feeling), which is how ISFP makes decisions; based on their own sense of what is morally correct.

Venus in Sagittarius likely gives her a strong personal moral code as Sagittarius is the sign associated with truth, higher wisdom, and morality. The second house represents things belonging to the self, which further supports having Fi as her dominant function.

Venus is also making a sextile aspect to Uranus. Uranus represents individuality and where we might be unique and go against the majority to some extent. With Venus in a harmonious aspect this isn’t the sort of rebelliousness that would cause conflict, but rather just make her sense of values very much shaped by her as an individual rather than being molded by the people around her. This is more support for a dominant Fi user. 

The auxiliary function of ISFP is Se, Extroverted Sensing. Se is taking in information from the environment using concrete tangible observations. I don’t have a good sample size for Sensor type MBTIs yet, but so far my theory is that Saturn is likely prominent in the charts of Sensors since Saturn represents structure, stability, and concreteness. Here, Saturn is not only in Taurus (a highly grounded and sensory based sign in astrology) but in an angular house (7th house), and planets placed in angular houses have an easier time expressing themselves than they would in cadent or succedent houses. Angular houses include the 1st, 4th, 7th, and 10th houses. 

Saturn is also making a harmonious aspect to the chart ruler, Mars. Mars trine Saturn has shown up in the natal chart of another Sensor type I have worked with, and shows someone who is methodical and strategic in their actions. To compare to the data on Intuitive types (which I have much more of so far), there are 2 personal planets aspecting Uranus/Neptune, but they’re Venus (more values based than showing someone’s propensity for sensing vs intuiting) and the Moon aspecting Neptune; however, the Moon is not as strong in this chart as Mars, since Mars is the chart ruler, and so whatever cognitive function is expressing through Mars would override the cognitive function expressed by the Moon (which I will address later).

On the chart ruler, Scorpio is traditionally ruled by Mars, and in this chart it’s in Pisces in the 4th house. The 4th house is perhaps the most private point in the birth chart, opposing the 10th house (most public part of the birth chart). The 4th house is home life, personal inner psychology, and corresponds with Cancer, an introverted sign. Pisces is also introverted (being a water sign) and so this to me would say this is the chart of an introvert. Scorpio rising also is often introverted unless the chart ruler shows otherwise. 

This chart also goes along with the data I’ve found so far on thinking vs feeling types, as feeling types usually have a Moon in either a water sign or a fire sign, and this has Moon in Aries. The Moon is also in harmonious aspects with Pluto and Neptune, which correlates in the charts of Intuitive users as the Ni function (Introverted Intuition). For ISFP, Ni is the tertiary function, and supports the dominant function Fi, Ni makes the Fi decisions and inner world very abstract and helps the ISFP intuitively make judgement calls based on values. In other words, the Moon’s intuitive nature (Moon sextile Neptune/trine Pluto) supports the unique and personal Venus value system (Venus sextile Uranus), and interestingly enough, the Moon and Venus form a trine in this chart further showing how they support each other.

Finally there is Extroverted Thinking (Te), the inferior function of ISFP. This is the least used of the 4 main functions of this MBTI, and I think this would show up in this chart as Mercury in Capricorn in a cadent house (3rd house). Mercury is also in accidental dignity in this chart as Mercury rules Gemini (corresponding to the 3rd house). Te for ISFP is where they might critique and refine systems and methods, which fits well with Mercury in Capricorn, as Capricorn is ruled by Saturn, the great refiner/critic of the zodiac, always seeking improvements and solutions.

MBTI in the Birth Chart: an INFJ

Continuing my series of posts on finding out what birth chart placements would correlate with one’s MBTI, today I’m covering the chart of an INFJ. The chart holder’s name, date of birth, time of birth, and location have been cut from the image.

As discussed in my previous post, right now I am focusing mainly on the state of the Moon and Mercury in the chart for obtaining the two dominant cognitive functions, with Mercury representing the perceiving function (how we collect information and process it) and Moon representing the judging function (the basis on which we make decisions, as the Moon is habits and instinctual patterns of behaviour that come naturally to us, in psychological astrology). This person has her Moon in Leo, which I have stated in previous posts more often correlates to “feeling” types in MBTI, being a fire sign, and especially because Leo rules the heart in the astrological hermetic man. This is a person who leads with her heart. To me, the conjunction of Sun and Moon in Leo also suggests a spiritually powerful person, which is one of the stereotypical personality traits of INFJ if we are to go beyond the standard cognitive function discussion of MBTI and into personality theory.

I say this because in hermetic astrology, the Moon represents one’s soul, and the Sun represents the spirit or higher self. Just as the Moon reflects the light of the Sun, the soul is meant to reflect the light of the spirit/higher self. This girl appears to have been born on or near a New Moon lunar phase, when the Moon (soul) was oriented towards the Sun (spirit). I don’t know this person and cannot say for sure whether or not she embraced this aspect of her natal chart, but the potential for strong spiritual inclination is certainly there, especially in conjunction of Leo/the heart chakra, with her Sun in domicile (strongest position for the Sun, as the Sun rules Leo and the heart).

Furthermore, her Sun/Moon conjunction is in her 12th house, the house of spirituality and dissolving of the ego. As we know, the ego can be the greatest downfall of Leo, but I believe the house placement mitigates this here as rather than her ego overtaking her, her luminaries have lit up matters of the 12th house in her life (spirituality, isolation, hidden enemies, self-undoing, dissolving of boundaries, etc.). This is likely a person who feels the need to care for people who may be or feel victimized, and she herself may have a risk of playing savior or developing martyr syndrome, especially in Leo, who is very generous and benevolent, but also wishing for praise and acknowledgement. In this way it’s possible for this person to victimize herself by being too self-sacrificing and tying her identity to how she suffers for others. These are classical traps for the INFJ, and part of their mission in this life is to overcome that and learn to set boundaries to protect themselves and avoid promising too much to others, eventually letting others down as they have taken on too many burdens in helping them, and becoming resentful at feeling taken advantage of by the people they help (without asking for anything in return, but not realizing they are creating a power imbalance). This is often the build up to the classic “INFJ door-slam.”

Her Moon is also conjunct Mercury in the 12th, which does suggest to me a person who unconsciously picks up information in a classic introverted intuition (Ni) fashion, the dominant function of an INFJ, and gives them that seemingly “psychic” manner of reaching insight in a way that feels out of nowhere to them and to onlookers. The 12th house is very subconscious and often hidden from the native, being behind the Ascendant (ego/identity) and therefore hard to consciously access.

She also has Mercury opposing Neptune, in the 6th house, in Aquarius. Neptune in the 6th can be a tricky placement, as the 6th house naturally corresponds with Virgo (the 6th sign), which is the opposite sign to Pisces (ruled in modern astrology by Neptune). I believe the 6th house is an important house for forming healthy boundaries, being opposite the 12th, which is about dissolving them (in order to achieve “unity consciousness”). 6th house is also the house of service and self-care, learning how to help others, but also to help yourself so that you can better help others. Neptune in the 6th, to me, further enforces the risk of developing “martyr syndrome,” in that it can show a difficulty in separating your own needs from the needs of others. I think this is especially true with Neptune in the humanitarian sign of Aquarius, who typically puts the needs of the group above the needs of the individual.

The Mercury/Neptune opposition also represents strong intuitive powers to me, with Neptune ruling Pisces, especially with the 12th house involved (corresponding to Pisces, the 12th sign). Mercury opposite Neptune is typically not a concrete thinker dealing in tangible facts and objective reality, but is much more abstract and deals in idealized potentials, something especially prominent for INFJs in particular (as far as idealism goes).

Mercury also makes a trine (albeit wide) aspect to Pluto from her 4th house in Sagittarius. I would consider this in the context of her chart to be another placement supporting her Intuitive typing for MBTI (and have seen a bit of a trend with Mercury/Pluto aspects in intuitive types, particularly intuitive feeling types). Pluto being deeply buried parts of the psyche, she is able to tap into these forces unconsciously to read situations and people instinctively. Mercury/Pluto aspects also tend to think deeply on topics and connect seemingly unrelated concepts into cohesive wholes (the convergent thinking of the Ni function). With her Sagittarius Pluto aspecting her Mercury, she likely is deeply in tune with the philosophical and spiritual concepts that are especially relevant to her generation (as Sagittarius is attuned to philosophy and spirituality, and Pluto is generational by sign placement).

This same Pluto trine and Neptune opposition apply to her Sun and Moon, which further reinforce intuition in her chart, particularly the aspects to the Moon (as in astrology, it is linked to one’s intuition). It’s also worth noting that the Sun appears to be her strongest planet (being both heavily aspected and in its own sign of Leo), because there was a very strong correlation between Intuitive MBTI types having their strongest planet aspecting one or more outer planet(s). Her Mercury and Moon appear to have equal strength, which is also interesting as Mercury is often affiliated in astrology with logic and thinking, and INFJs have been said to be the most “balanced” of the feeling types in terms of weighing decisions between what is logical/effective and what they believe to be morally correct.

I also believe Neptune being so strong in her chart is a good argument for using extroverted feeling (Fe, the auxiliary function of INFJ) over Fi, as Fe users again are more focused on the harmony of the collective group they are in, sometimes at the expense of their own values. In this person’s case, she likely does have a strong sense of values with Venus in the 1st house, but again those values are around service to others, with Venus in Virgo. She may have an inner conflict between her wish to serve others and create harmony and her need for individualism, with Venus opposing Uranus in her 7th house. Again, this can show sudden breaks in relationships with others (with Uranus being a disruptive force and the 7th house being relationships and partnerships), again we see the “INFJ door-slam.”

In the personality theory side of MBTI it also makes sense for her Ascendant to be in Virgo, which is an introverted sign, and the sign of helping others. Venus in the 1st can certainly make someone likeable and social, and INFJ is also often considered the most “extroverted” of the introverts, meaning they socialize more easily than some of the other introverted types, but still need time in solitude to recharge.

That about sums up this analysis, thanks so much for reading. I am hoping to post these more frequently and intend to post an article for everyone who sends me their birth chart/birth chart info and MBTI. Please Contact me if you would like to participate in this study!

Exploring MBTI In the Birth Chart: An ENFJ

In my previous posts about correlations between MBTI and astrology birth charts, I was sharing and examining data from a pool of volunteers who shared their MBTI and birth chart with me, looking for patterns/trends among the different types and their charts. My new focus (at least for now) is going to be on analyzing individual birth charts to look at what might show their preference for function stack orders. All charts are shared with permission from the owner, and no identifying information will be shared.

If you have previously shared your birth chart and MBTI with me, I will likely be contacting you at some point to request permission to use your chart for the subject of one of these articles. If you have not shared your birth chart and MBTI with me previously but would like your chart featured in one of these articles, please feel free to Contact me with your information!

ENFJ Birth Chart

Anyway, here is the chart of an ENFJ who has consented to having her information shared. As stated in my previous post, the Moon tends to show what kind of judging function one relies on most. Water and Fire element Moons tend to use Fe or Fi as their primary judging function, and Earth and Air Moons tend to use Te or Ti as their primary judging function. This is based on data collected from various MBTIs so far. It does make sense, given that Water and Fire types tend to be more values-driven and in tune with emotions (their own, and that of those around them), while Earth and Air types tend to be more logic-driven and focused on systems and structures.

ENFJ has her Moon in Aries, a Fire sign, and so this is consistent with my current available data of Fire Moons having a preference for Fe/Fi as their primary judging function. As for determining whether they will use Fi or Fe, I might look at aspects to the Moon for further clarification. In this case we have Moon trine the Sun, Moon trine Uranus, Moon square Venus, and Moon square Jupiter, with the last aspect being the strongest, with a 1 degree orb, and Moon square Venus being the weakest aspect at a 7 degree orb. As the closest aspects between two planets tend to be the most powerfully expressed, it seems logical to examine Moon square Jupiter first. The energy of Jupiter is to cause expansion, to grow, to externalize, and is very much tied to higher value systems and beliefs. I would say Jupiter, as a planet, has a natural extroverted energy to it. The square is a tension aspect and demands dynamic action. The Moon/Jupiter square has a tendency to create quick judgments (aka, decisions) based on value systems and emotions, which matches the extroverted judgers (as they lead with a judging function and use perception as their auxiliary function).

In MBTI, the function stacks are ordered so that whatever the dominant (1st) function in the stack is, the inferior (4th) function will be the opposite. For ENFJ, the inferior function is Ti (introverted thinking), and is their weakest function. An interesting thing to note is that the Moon/Jupiter square tends to show someone who is reluctant to listen to their intellect. I absolutely do not mean that people with this aspect are not intelligent or are irrational. Rather, these people typically lead with their heart first. Any aspect between the Moon and Jupiter tends to show a very generous person who will often put the needs of others over their own (Fe). Moon/Jupiter aspects are often found in people who place a high value on relationships with others. This is further emphasized by the house placements, Moon in the 5th and Jupiter in the 2nd (house of values).

Likewise, Sun trine Moon is another placement that values relationships and especially harmony within them. This placement (along with the former one) makes the native generally well-liked, as they make others feel very accepted. Moon trine Uranus also tends to focus on the good of the group, as Uranus is transpersonal and group-oriented, being the modern ruler of Aquarius.

In my earliest MBTI astrology posts I found a strong tendency for the the most powerfully placed planet in the chart (by essential dignity) to be in close aspect with one or more outer planet in a birth chart (Uranus/Neptune/Pluto) in the charts of my Intuitive-type MBTI samples. However, as of right now this is still purely a hypothesis, that the strongest inner planet will aspect an outer planet specifically in Intuitive users. I have not yet collected charts from Sensor MBTI users to compare this against, and so it could be that Sensors also have this happen in their charts with the same frequency, which would mean that is not an indicator of whether someone has a preference for intuition vs sensing as their primary perceiving function. In other words, I have merely observed a pattern but not yet tested it. If you are a Sensing type (S is the 2nd letter of your MBTI) I am especially interested in seeing your birth chart…but I am currently looking for ALL MBTIs for this study, including more Intuitives.

Along with the Moon, Mercury represents the other major facet of the mind; how we communicate and learn information. For now, I think it might make more sense to look at the state of Mercury as it correlates to the primary perceiving function (the information gathering function), i.e. whether one is a “sensing” type or an “intuiting” type. It’s very interesting to me that this ENFJ has her Mercury in exact conjunction with Pluto, and a tight sextile with Neptune, as these are planets I have previously assumed to be connected with intuition. Neptune having domain over the ocean, it has an archetypal link to the collective unconscious, dreams, and yes, intuition. The primary perceiving function of ENFJ is Ni (introverted intuition).

As MBTI cognitive function stacks are less holistic than an astrological birth chart is intended to be (while MBTI primarily represents how we make decisions and gather information/interact with the world on a mental level, birth charts represent many other things), I believe that the Moon and Mercury are likely the most important factors to consider when comparing someone’s birth chart to their MBTI. The Ascendant/first house might also be important, since that also represents how we interact with the external world. This person has her Sun conjunct her Ascendant, in Sagittarius. The Sun is considered in astrology to be yang/male/extrovert energy, as is Sagittarius as it’s the fire element. It’s supported by a soft aspect from Mars, another masculine energy planet, which supports this person being extroverted if we are looking outside of the cognitive function stack analysis and at whether someone is “an extrovert” vs “an introvert.”

Anyway, that’s all for this one. If you would like your birth chart posted up here and compared with your MBTI for research purposes, please visit my contact page and send me a message!

MBTI & Astrology Pt. 4: Thinking/Feeling, Examining The Moon

Up until this point my MBTI/astrology research has focused on showing possible correlations with Intuitive types (“N” users) and birth chart aspects. As I continue to collect more sample charts to study, I am finding a consistent trend: in nearly every case, the personal planet with the strongest placement in the birth chart by essential dignity is in aspect to an outer planet in the birth chart. So far, there is a slight preference for Uranus aspects in extroverted intuition users and a slight preference for Pluto aspects in introverted intuition users. Neptune seems to be equally frequent across both types of intuition functions.

I would like to shift the focus for now to examining “thinking” types vs. “feeling” types. To determine this function I looked at the state of the Moon, as it represents emotions, habits, and instincts; how does one habitually behave? The first thing I found is that thinking types more often have Moon signs in either air element signs or earth element signs (72% total). 28% of thinking types had a Moon in a fire or water sign. Fire was the least represented at just 9% of the total sample, with one Sagittarius Moon (an INTP) and one Aries Moon (an ENTP). This makes sense to me, as fire is known to be passionate and emotive. 18% of thinking types have water Moons, and of those, they were either Pisces or Cancer, with no Scorpio Moons. Of the earth Moons, there was a slight preference for Virgo over the other 2 earth signs. Of air, the Moons were mostly Gemini or Aquarius. These all make sense to me, as Virgo and Gemini are both ruled by Mercury, which represents thought/the mind, and people with Moons ruled by Mercury would tend to rationalize their emotions and analyze them. Aquarius, of course, is highly cerebral, and these Moons showed up in ENTPs, which also use tertiary Fe. That again makes sense as Aquarius focuses more on what is best for the group (Fe) yet they are still focused more on logic and reasoning than feelings.

As for the feeling types, the results were a little less strong but still showed a preference for fire and water Moons at 67%, with air and earth Moons at 33%. Fire and water were equally represented. There were no Sagittarius Moons, with only Leo and Aries showing up here. As Sagittarius is the most cerebral of the fire signs, this also makes sense, with Leo and Aries being more personal and emotive. All 3 water signs showed up with about the same frequency. For earth, there were no Virgo Moons in the feeling types, and about equal Capricorn and Taurus.

A note on the direction of this research:

Until I have a much larger sample size, it’s going to become very difficult to lock on to specific function stacks in correlation to birth chart placements. For now, I’m going to shift the focus of these posts to analyzing individual charts to compare against MBTI type. I’m hoping that might help me gain some insight as well. I will not be posting any identifiable information of anyone, or their birth chart (unless they expressly grant me permission to do so). Rather, I will just be discussing their placements and explaining how these would correlate with their function stacks.

Thank you to everyone who has participated so far. If you are interested in having your chart analyzed for correlations with your MBTI type, please Contact me and let me know; this is obviously a free service as it helps me with my research. I am looking for ALL MBTI types.

MBTI And Astrology Part 3: Intuitive Types and the role of Essential Dignities and Pluto


First of all, thank you to everyone who has been kind enough to allow me to use your chart for this study. In my last post I was working with the charts of 22 “Intuitive” types (people who use intuition as either their dominant or auxiliary function in the cognitive function stack). I now have 31 to work with, with 10 of those being Ni users and 21 Ne users. I feel that for now I should retract the part of my theory that suggested “Ne” is associated with masculine inner planets (Sun/Mars) contacting outer Uranus and/or Neptune, and “Ni” being associated with feminine inner planets (Moon/Venus) contacting Uranus and/or Neptune. There is still a very high correlation with Ne/Ni users having inner planets in contact with outer planets; but Ni users, so far, have contacts from outer planets to masculine inner planets just as often as feminine inner planets. See my last post (Part 2) for more details on that.

Updated statistics: 84% of my sample of Intuitives have Uranus in contact with a personal planet in their chart (up 3 percentage points from my previous data). 87% have Neptune in contact with a personal planet in their chart (down 9 percentage points from my previous data, but still a significant percentage). 74% have both Uranus and Neptune in contact with a personal planet in their chart.

Moving forward, one of my contributors asked if perhaps contacts to personal planets and Pluto played a role in showing Intuitive types in a birth chart. The results so far: 87% of Intuitive users have an aspect between Pluto and a personal planet in their chart (same rate of frequency as Neptune). As Pluto in astrology is connected with the Underworld (and therefore hidden things), I was curious to see if there is any correlation with birth charts of people with a preference for Ni (Introverted Intuition) and a higher rate of Pluto to personal planet contacts, than for Ne users. Since the previous idea that masculine/feminine personal planet contacts to outer planets correlating with a preference for Ne or Ni is, so far, not true, I wanted to see if maybe it has more to do with the outer planet in question showing a preference for Ne or Ni.

The results so far: Ne Users: 82% of Ne users have contacts between a personal planet and Pluto, 86% have contacts between a personal planet and Neptune, and 91% have contacts between a personal planet and Uranus.

Ni Users: 90% of Ni users have contacts between a personal planet and Pluto, 80% have contacts between a personal planet and Neptune, and only 60% have contacts between a personal planet and Uranus.

Based on my extremely limited sample size for Ni users, there does appear to be a slightly higher occurrence of Pluto/personal planet contacts for Ni users over Ne users, while Ne users more often had contacts from Uranus. I’m hoping this will remain consistent as I gather more participants, because it really would fit the definitions of Ne and Ni so well, with Ne being focused on many possible ideas, and Ni more convergence of many ideas (system-building). Time will tell if this holds up!

Essential Dignities, Planetary Friendships, and role in Dominant/Auxiliary Function

I also got a tip from another person that I should consider essential dignities of planets in this study. The QRD on essential dignities is that planets operate at greater strength or weakness in a birth chart relative to the signs they are placed in. There’s more to it than that, but that’s the most basic part of it anyway. A planet is considered to be operating at its strongest when placed in the sign it rules (Venus in Libra/Taurus, Mars in Aries/Scorpio, etc.). Such a planet is called “in domicile.” A planet is considered to be operating at its weakest when placed in the sign opposite of what it rules (Venus in Aries/Scorpio, Mars in Libra/Taurus, etc.). The second strongest placement for a planet is called “exalted,” and the second weakest placement for a planet is called “in fall;” a planet is in fall when it’s in the opposite sign of where it’s considered exalted.

Beyond that, planets also have planetary “friendships” with each other. When a planet is in a sign ruled by a planet it is “friendly” with, it’s said to have a “friendly” position in the chart. I would consider this less strong than domicile or exalted, but more powerful than in fall or detriment. A planet in a sign ruled by a planet it is “enemies” with is said to have an “inimical” position in the birth chart, which I would consider weaker than in domicile, exalted, or friendly, but still stronger than fall or detriment. Some planets are “neutral” with each other and so planets placed in a sign ruled by a planet it’s neutral with has a neutral position, which is just right in the middle of all possible placements in terms of relative strength.

What does this all mean for MBTI correlations? I first checked to see which planet has the strongest position in each subject’s birth chart. Sometimes, one or more planets would tie for the strongest position, which I also considered (this occurred in 8 charts). Then, I checked to see if the strongest positioned planet aspected the outer planets in the chart.

The results: In 94% of cases, the strongest positioned planet in the birth chart aspect an outer planet. This is true for 95% of the Ne/Ni dominant users (ENTPs, INFJs, and ENFPs were my samples) and 89% of Ne/Ni auxiliary users (INTPs, INFPs, and ENFJs were my samples). Conversely, when I checked to see if the weakest planet by sign position in the birth chart aspected an outer planet, this occurred 58% of the time across all Intuitive user samples. As for the 8 charts with 2 or more planets tied for strongest position, 63% of them had both tied planets aspecting an outer planet. 25% of those charts had two personal planets tied for “first,” but only 1 of them aspecting a personal planet. One of the charts had three personal planets tied, and two of their 3 strongest placed planets had an aspect to an outer planet.

One chart had all five of their personal planets placed in “friendly” position; therefore had no strongest or weakest planet. However, 4 out of 5 of their personal planets were in aspect to all three outer planets.

More research is needed, but so far it does appear that essential dignities and planetary friendships aspecting outer planets do correlate with a preference for intuition. As far as which outer planets contact the strongest placed personal planet, the results were distributed nearly evenly between Uranus and Neptune, at 48% and 45% of the time, respectively, and 35% of the time for Pluto.

A Quick Note on Chart Ruler and Intuitive Users

I also checked how often the chart ruler (ruling planet of the Ascendant) came into aspect with an outer planet. In 74% of cases this was shown to be the case; a weaker rate of occurrence than for planets in the strongest position in the charts.


  • There is still a strong correlation between outer planets Uranus and Neptune in a birth chart aspecting personal planets among Intuitive MBTI types.
  • Additionally, there is an equally strong correlation between Pluto aspecting personal planets in the charts of Intuitive MBTI types.
  • Former speculation that a preference for Ni or Ne can be determined relative to the feminine or masculine nature of the personal planets in aspect to outer planets no longer appears to be true.
  • There is a strong correlation between outer planets aspecting the strongest placed personal planet(s) in a birth chart and preference for Ni/Ne.

More participants are needed!

MBTI and Astrology Part 2: What Shows An Intuitive?

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 pearl@astrotomey.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

King Ferdinand as Neptune – Guillielmus Becanus

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

Uranus and the Dance of the Stars – Karl Friedrich Schinkel

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 pearl@astrotomey.com!

Astrology and MBTI, Cognitive Functions, Myers-Briggs

Every once in a while I go on a Myers-Briggs or Jungian typology binge. It’s a hotly debated topic; some people think it’s absolute bullshit pseudoscience, while others laud it as legitimate psychology. I try to find the benefit in most any system I come across and keep an open mind about it; after all, people often have very similar beliefs in terms of extremities when it comes to astrology.

Since I like stringing concepts together and finding correlations in things in general (typical human, I know), I’ve been curious about how astrology and MBTI might work together, particularly when studying the cognitive functions stacks. If you’re here reading this, I’m going to assume you know about the function stacks of MBTI personality types already. If you don’t, consider checking out this website for some good introductory info on learning about cognitive function stacks, what each one does, and how they link together for each of the 16 personality types. If you want to take one of her personality type tests, there are many options online that are free. This one is pretty good.

I would not recommend 16personalities.com, the questions are very generic and there is an extremely high rate of mistyping happening. Basically, if you’re not a complete NPC you’re going to get “N” for your 2nd letter of your 4 letter type with that test, even though everyone uses both intuition (N) and sensing (S) to some degree, somewhere in their function stack. It basically makes “sensing” types seem stupid by the questions ask, in my opinion, which is ridiculous because there are plenty of intelligent sensing types capable of things like projecting their reasoning into future outcomes. Between 70% and 80% of the population is xSxx, and it doesn’t mean you’re not unique or intelligent if that’s your 2nd function. I believe 16 Personalities also skews a bit more towards “feeling” types. The questions used to determine “thinking” vs “feeling” make thinking types seem like automatons. I’ve seen countless people get mistyped on that test as INFP, for example.

Anyway, back to the astrology/MBTI correlation. Most of the articles I’ve found linking astrology to MBTI are pretty generic click-bait focused primarily on Sun signs (“This is your Meyers-Briggs type according to your Zodiac sign!”), or people just bashing astrology and saying there is no possible correlation because astrology is bullshit. Which is ironic, given that MBTI is based on the theory of psychological type, developed by Carl Jung, who was the man to introduce astrology into psychoanalysis in the western world, but whatever. I’ve seen the argument go the other way, too; that MBTI is just astrology “dumbed down.”

I don’t think these two systems are necessarily mutually exclusive. I have seen the limited sample data of people’s Sun sign relative to their MBTI, showing there is no significant correlation in most cases. Again, this is based on Sun signs only, and we all know how reliable that is for measuring anything (about as reliable as giving a physical description of a person when you’ve only seen a close up of their nose).

So I’m taking this matter into my own hands and trying to see what might be the most likely MBTI for people based on their astrology, relative to function stack orders for each type. I’m specifically focusing on the first 2 functions for each type, since they define the last 2 functions by opposition. I’m still basing it on the Sun of the birth chart, but also the Moon, and not just what sign they are in, but also how they are aspected in the chart (what planets aspect each, what types of aspects), as well as the house(s) the Sun and Moon fall in.

My Process

I am correlating different Sun/Moon signs/positions/aspects with the dominant function and auxiliary function for each MBTI. The most general, basic guidelines I’m setting are that masculine signs and odd-numbered houses are extroverted energy, and judging functions, while feminine signs and even-numbered houses are introverted energy, and perceiving functions.

Obviously these are not hard and fast rules! The aspects to the Sun and Moon would matter. For example, if the Sun is receiving an aspect from Jupiter and/or Mars, it would give it a more “extrovert” flavor, even in a feminine sign, especially if Jupiter and/or Mars are in masculine signs and/or houses. If the Sun is receiving aspects from Saturn, that would show a more introverted flavor, even with the Sun in a masculine sign. A chart where the Sun represents the dominant function, and the Sun is aspected by Neptune, would show a perceiving dominant function (most likely intuition).

Whether the Sun represents the dominant function or auxiliary function would depend on its strength in the chart relative to the Moon. Strength of Sun vs. Moon in the chart is determined by the sign each is placed in, how many aspects are made to each, whether either one is conjunct an axis point, whether either is the chart ruler, etc. The weaker of the two luminaries would represent the auxiliary function.


My Chart

Here is my own chart as an example. I’ll start by saying that my Moon is actually my dominant planet in my chart. Pisces is already a stronger placement for the Moon than Scorpio is for the Sun, I think, but moreover, I think having a nocturnal chart (being born at night) also gives my Moon some more power. Beyond that, I have 6 aspects happening to my Moon, with only 4 to my Sun. Basically, my Moon governs my dominant function rather than the Sun.

Pisces being a feminine element sign, my dominant function would be a perceiving one (sensing or intuition). I think having the Moon in any water sign is most likely going to lean towards the intuitive perception. (Not always though; again, the house should be considered, as well as aspects from other planets, and what signs/houses those planets are in). I think that’s further supported in my case by the square from Uranus in Sagittarius, as Uranus aspects often show sudden bolts of insight that just seem to “come out of nowhere,” and Sagittarius also being an intuitive sign. Also, my Moon is in a water house (8th house).

Ok, so I have Intuition as my dominant function, but is it Extroverted or Introverted? It’s basically on the very cusp between the 8th house and the 9th house. If we were using whole sign houses it would be a bit more clearly in the 8th house, and even by the shown house system, most astrology websites classify that as the 8th house, and I feel the 8th house hits home a little bit more than the 9th for me when it comes to my Moon, so I’m going with 8th, which is a water house (feminine, introverted). But, my Moon is also conjunct Mars (out of sign, but still), and my Mars is in a masculine house, and in Aries no less, the strongest sign for Mars to be in. That would make my Moon look more extroverted, with the masculine power of Mars hitting it. Plus, it’s getting an out of sign sextile from Jupiter, another extrovert aspect by my own rules. However, my Jupiter is weak, being in detriment in Gemini. It’s also coming from the 10th house, a “feminine house.” Overall, I think it’s a little hard to argue a case for an 8th house Moon in Pisces, squared by Saturn (which restricts/limits/dampens what it squares) being extroverted. That would mean Introverted Intuition for my dominant function.

That gives us the choice of INTJ or INFJ for MBTI. The auxiliary functions for those are Extroverted Thinking and Extroverted Feeling, respectively. My Sun is in a water sign as well, Scorpio. Since my dominant function is a perceiving function, my auxiliary is a judging function by default, because that’s how MBTI systems operate. Water signs, obviously, are linked more to feeling than thinking. My Sun is also in the 4th house, a water house.

You may be thinking at this point, that my Sun would suggest an introverted function as well, which obviously wouldn’t go with either INTJ or INFJ for auxiliary function, since the auxiliary must be opposite the dominant in terms of introverted vs. extroverted. Well, there are still aspects to the Sun to consider. I have Moon and Mars trine the Sun as well as Jupiter opposing the Sun. Again, Jupiter is weak, and Mars is really strong. We have to take into context that we are now applying this to the judging function as well, rather than the perceiving function. The auxiliary function in this case is how we make decisions, judgement calls, how we interact with others. I think the Sun/Moon trine really does speak more to interpersonal matters than perception of the world.

Here is what Astrolibrary.com has to say about Natal Sun trine Moon: “They have an ability to be persuasive while communicating. They are understanding and would do well in any job where inter-personal skills are required. They are good peacemakers or moderators between people who are arguing.

This person doesn’t usually have ego issues. They don’t mind helping others. They are generally caring. They are good listeners and considerate friends. They are sincere, honest, warm, and friendly. The person with sun trine moon has a healthy self-confidence and optimistic attitude.”

As for Sun trine Mars, it typically shows someone who is goal-oriented and driven, with a happy social life, especially if Jupiter is involved in the aspect. My Sun is also not getting any “afflicted” aspects like that square from Saturn to my Moon, and so even though I am an introverted person, my Sun, being my auxiliary function equivalent, is getting a lot of extroverted support when it comes to my feelings about other people. And that is exactly what it means to have “extroverted feeling” in your top 2 functions; someone who makes decisions based more on the feelings of others than their own personal values. Introverted feeling would be more focused on your own internal value system. If I had, say, the Sun in the 4th house but in Aries, conjunct Mars, and square Saturn, that might translate to Introverted Feeling (and it would likely also mean the Sun would represent my dominant function, with the Sun being exalted in Aries).

My “official” MBTI as per professional testing matches up to this analysis: INFJ.

Spouse’s Chart

Here’s one more example that is a bit trickier. This is my spouse’s chart, and as you can see he has a massive Aquarius stellium happening across his 12th and 1st house. Between the Sun and Moon, which one represents the dominant function? The Sun is in detriment in Aquarius, but it is receiving trines from Jupiter and Saturn. However, because it’s conjunct the Moon, the Moon is getting those same trines. The Moon is only in peregrine condition in Aquarius, a more neutral position. They’re both being squared by Chiron as well. Ultimately, I’m going with the Sun for dominant function, because while they are both conjunct the South Node (a weakening aspect), the Moon is closer to an exact conjunction. Also, the Sun is conjunct the Ascendant, giving it more power, while the Moon is a bit too far in the 12th house to be considered conjunct the Ascendant, more “hidden” from the chart holder, as the 12th house is representative of things hidden from the native’s conscious psyche. The Sun is also an angle ruler in his chart (7th house), where the Moon is only the 6th house ruler.

With that established, let’s note the condition of the Sun by sign, house, aspect. Aquarius being an air sign makes it masculine, which would put him as Judging dominant function, right? A cursory look would say he has Introverted Thinking as his dominant. But, that’s not necessarily so. His Sun is technically in his 12th house, but again, it’s pretty close to his Ascendant, and by orb of allowance, he’s well within a conjunction to that. His Sun being the very social Aquarius, conjunct the Ascendant, and also receiving a trine from the benevolent and warm Jupiter, puts him in the extrovert category. So Extroverted judging function, thinking or feeling?

Again, it’s not quite that simple. His Sun, while very much an extroverted Sun by astrology standards, is getting some power from the 8th house, a water house (the Scorpio house), which again is intuitive. While in a masculine (i.e. “judging” sign), being in his 12th house and aspected by planets from the 8th supports extroverted intuition. This also makes sense for Aquarius energy in general, being very future-oriented and naturally skilled at envisioning multiple possible outcomes.

Every dominant function is shared between two types, so his are narrowed down from here to either ENFP or ENTP (auxiliary introverted feeling or introverted thinking). This is where it gets a little tricky, because his Moon is in the same house as his Sun and receiving the same aspects from Jupiter and Saturn in the 8th house. So we’re dealing with feminine houses again, and while it may be tempting to automatically equate feminine houses with feeling, it’s important to consider the houses in question. The 12th house (along with the 4th) is certainly the house most strongly associated with intuition, but any planet there is going to have its energy a bit dissolved and inaccessible to the native.

While ENFPs identify with their emotions very freely and easily, 12th house Moons…not so much. And while both his Sun and Moon are trine to his Saturn, it’s generally much more difficult for the sensitive “mother” archetypal energy of the Moon to deal with any interaction from cold, rigid Saturn than it is for the Sun. Sun and Saturn can both represent masculine/”fatherly” energy and so mesh a bit better together than Moon and Saturn. In both cases (Sun/Moon) a trine from Saturn would refine them, but the Moon is a bit more hampered than the Sun. In other words, Moon trine Saturn comes off more emotionally distant than Sun trine Saturn, which deals less with emotions.

His Moon is also conjunct his South Node. The South Node is often equated with “baggage” carried over from the past life, and where we might revert to in times of stress and emotional upset. In Vedic astrology, I’ve read it referred to as a “shadow planet.” This reminds me of the shadow functions of MBTI (cognitive functions we fall into under extreme duress, generally expressed in an unhealthy manner); the 3rd shadow function of ENTP is Introverted Feeling (the “Trickster” function). Meaning, Introverted Feeling would more likely be displayed as a shadow function in his case, with Moon conjunct South Node in 12th house. Combine that with the Aquarius Moon’s tendency to rationalize/intellectualize their emotions and I think there is a pretty strong case for ENTP here.

In college, he was typed as ENTJ; however, it’s certainly not unheard of for people to either mistype or to change somewhat over time, as personalities are not stagnant. This is one reason why, overall, I much prefer astrology over MBTI, as birth charts, while seemingly static to the untrained eye, do allow for and encompass the full spectrum of human experience from birth to death, and even death to birth/rebirth as shown in the lunar nodes. One’s MBTI may change slightly over time (or you may spend years operating in “grip stress” and leaning on shadow functions due to stressful life conditions, causing you to “mistype” as you haven’t been expressing a healthy version of yourself), but your birth chart’s essential mapping does not change, because it doesn’t have to; it shows your entire life potentials, including opportunities for change and growth, from its very creation.

And, when I showed my spouse information on the ENTP type, he did agree it does sound more like the person he is today (over a decade after he was typed ENTJ).

Spitball Series: Asteroid “Sirene” and Her Impact on Singing Style, Voice

Herbert James Draper, Ulysses and the Sirens

Asteroids are a topic I’ve been interested in for a while now, but I’ve found limited information on them so far. Most of the available literature is on the major asteroids, Juno, Vesta, Pallas, and Ceres (which is more of a dwarf planet than an asteroid). I am hoping to use some of my own findings to draw some conclusions on smaller asteroids and their implications in astrology.

Today, I would like to focus on Sirene. There is precious little about this one that I have found. Typically, most articles/posts discussing asteroids that mention Sirene, describe it as the energy of luring someone astray, to their doom even. I understand the reasoning, due to the mythology of Sirens as dangerous creatures that would lure sailors with their beautiful songs, and cause shipwrecks. So when a lot of people talk about using the asteroid Sirene in a reading, their go to is that person uses deceptive/convincing words on other people.

Typically, what I see with most minor asteroid research online, is that most astrologers use only asteroids that are conjunct a personal planet. They might also include a minor asteroid conjunct an outer planet IF that planet is also tightly aspecting a personal planet in that chart as well. For example, a minor asteroid such as Sirene conjunct Uranus in the birth chart, and Uranus squares the Moon. Or, if Uranus is the chart ruler, it becomes a personal planet as well, and so would not even have to be aspecting another personal planet for the asteroid conjunct to be considered significant. The same astrologers that follow this rule typically keep the orb for conjunctions to minor asteroids tight, at 3 degrees or less, though this can vary a little between astrologers and I’ve seen some go as wide as 5 degrees.

Anyway, onto Sirene. I was thinking about it a while back and wondering about the musical/vocal aspect of the myth this asteroid is named for, rather than just focusing on the negative connotations of deception and misleading others. A big trait of the Sirens is that they have beautiful voices. Is that something we could apply to a birth chart reading? Is there a correlation between the vocally talented and aspects to this asteroid in the birth chart? What about having a really “annoying” or abrasive voice? Would Sirene come into play there?

My first thought was to look at the charts of some famous pop singers to see what Sirene was doing there. I did find aspects from Sirene to personal planets in the charts of many of them, including the divas with cult-like fan worship such as Mariah Carey, Whitney Houston, Judy Garland, Beyonce, and Adele. I also found aspects from Sirene to personal planets in the charts of Pat Benetar, Victoria LeGrand of Beach House, Celine Dion, SIA, Bjork, and Angel Olsen. Sometimes it was an aspect to the Sun, sometimes the Moon, sometimes Venus, Mercury, or Mars, and sometimes it was hitting multiple personal planets at once. In almost every case (except Celine Dion and SIA) the aspects were hard; conjunctions, squares, and sometimes oppositions. Celine Dion and SIA only had soft aspects to personal planets, though Celine did have Sirene conjunct outer planet Neptune (which makes sense, given Neptune is considered to be associated with music).

I found similar trends with modern male singers, including Prince, James Mercer of The Shins, Curt Smith of Tears for Fears, Claudio Sanchez of Coheed and Cambria, and Freddy Mercury.

The issue of course being that music is such a highly subjective topic, and what one person finds aurally appealing another person may not like at all. For the most “objectively talented” vocalists in terms of traditional technical singing ability, I checked the charts of several famous opera singers. I found aspects from Sirene to personal planets in the charts of Ettore Bastianini, Enrico Caruso, Julia Migenes, Tito Schipa, Ruggero Raimondi, Beniamino Gigli, Maria Callas, Elisabeth Schwarzkopf, Birgit Nilsson, and Joan Sutherland.

Other impacts of Sirene on vocals

I also checked the birth charts of people who are/ famous for just having generally unique voices, for better or worse. I think most people would agree these people moreso fall into the “for worse” category: Gilbert Gottfried, Kristen Schaal, Jennifer Tilly, Fran Drescher, Kim Kardashian, and Paris Hilton also all have aspects from Sirene to personal planets. Roseanne Barr has Sirene conjunct Chiron, and while Chiron isn’t a personal planet, he is associated with pain, and I do think people generally find Roseanne’s voice painful to listen to.

This is all just preliminary research on my part, and a larger sample size should be studied before drawing any conclusions. However, it’s interesting that out of the vocalists I looked up, only 2 had no major aspects in their chart coming from Sirene (those being Shakirah and Elvis Presley). In most cases, the orbs are 3 degrees or less, but in some they are a bit wider (typically 5 or 6 degrees for the wider ones, and these aspects are often to the natal Sun, which tends to get a wider orb allowance than other planets in general).

Also, I am not attributing aural talent or vocal uniqueness solely to Sirene. As with anything in a birth chart, it needs to be considered holistically in conjunction with other factors in the birth chart (Neptune placement/aspects, Venus, Mercury, Pisces/Taurus/Libra, 12th house, etc.). This asteroid is just another tool in the tool belt that one might use.

And again, I can’t stress enough how subjective this matter is. While one can be technically musically talented, having a unique style and being able to successfully emote and elicit emotion from one’s audience is at least as important as technical ability (a bit more so, in my opinion). For example, people hail Mariah Carey for her singing talent, and while she does have great range and can do a huge variety of things with her voice, I personally don’t care for her music at all. Instead of being tone deaf, I find her emotionally deaf, her singing feels hollow, empty, and flat to me. How a singer feels is more important to me personally than how he/she sounds.

The Takeaway

Sirene does seem to have some effect on the voice of people who have it in aspect to personal planets in their chart, in a way that grabs the attention of the listener, much like the sirens in myth.

Star Trek Next Gen Characters Are Just Hyperbolic Zodiac Signs

I’m taking a more joking/light approach for this post. My last posts were a bit serious, dealing with outer planet karma in birth charts, and I thought it would be fun to combine 2 of my favorite things for this post: astrology and Star Trek. If you are offended by facetious, sweeping generalizations of zodiac signs (or are just really emotionally invested in Star Trek TNG characters), this post might not be for you.

My argument: every main character of Star Trek TNG is an exaggerated zodiac sign. Whether that’s the result of their race (such as being a Betazoid or a Klingon, for example) or not, the characters are representative of very distinct archetypes. I’m thinking that’s because the overarching goal of Star Trek is not intricate character development, so much as it’s about retellings of the same themes we’ve been dealing with in mythology since the dawn of man. But with a sci-fi spin. Here’s my opinion on the main characters of the show and why they fit the most stereotypical themes of different signs.

Jean Luc Picard

Of course, I have to start with the captain of the Enterprise, who is very clearly the archetypal Capricorn. When I was looking this up for fun some time ago I only found one post online about it, and the writer said they thought he was an Aquarius. While she/he had some funny arguments for that, I have to disagree. Picard is all about leadership, and even though he’s not a biological father to anyone, he’s definitely the father figure of the show, which matches the Saturn (father time) energy of Capricorn perfectly. His whole life and sense of worth hinges on his status, career, reputation, and personal integrity. He’s the lawful good aligned guy who takes no bullshit. While Aquarius is also affiliated with Saturn, I’m more inclined to associate it with its modern ruler, Uranus, as the energy feels more fitting overall. Saturn and the 10th house really belong to Capricorn.

This quote from Picard really goes with the Capricorn/Saturn theme of time:

“Time is a companion that goes with us on a journey. It reminds us to cherish each moment, because it will never come again. What we leave behind is not as important as how we have lived.”

Saturn/Capricorn also has a way of stripping away all that is illusory and facing cold hard reality:

“If we’re going to be damned, let’s be damned for what we really are.”

“It is possible to commit no mistakes and still lose. That is not weakness, that is life.”

William T. Riker

I’m picking Leo for Riker. He loves creative performance and being the center of attention, both very Leo things. He was the star character for the play “Frame of Mind” in the episode by the same name. Which is the best Riker-centric episode. Even his favorite musical instrument screams “Leo,” the trombone; it’s the color of Leo, gold (well, yellow brass, but whatever), it’s large, loud, and imposing. Also, Riker is a perpetual manchild, which goes well with the Leo/5th house theme of children. He has the Leo smugness as well as the Leo ego (with Leo’s ruling planet being the Sun and the Sun representing the ego, this makes sense). Leo/the 5th house is also house of romantic liaisons and sex, but not the really intense, intimate 8th house kind of sex. And Riker seems to get googly-eyed over any female who gives him the time of day. Sometimes they don’t even have to be biologically female (see episode 117, The Outcast).

Some Riker quotes showing he’s the Leo archetype:

“Deanna, facing death is the ultimate test of character. I don’t want to die, but if I have to, I’d like to do it with a little pride.”

“What’s a knockout like you doing in a computer generated gin joint like this?”

“The name of my ship is the Lollipop. It’s a good ship.”

Dr. Beverly Crusher

Crusher’s another fixed sign; the Taurus archetype. Stubborn, and maybe too stable at times. She’s probably the most predictable character on the entire show, and that’s saying a lot. Her field of expertise deals with the very tangible realm of the human body (or alien body), and Taurus is all about tangible experience. She’s a realist to a fault, except maybe when it comes to love, when she can become a bit of a hopeless romantic. Taurus is ruled by the love planet Venus, so that checks out. She doesn’t seem too capable of the higher, abstract thought of some of the other characters on the show. She’s textbook “earth energy.”

You might be wondering why I would say that and simultaneously peg Picard as an earth sign, with his waxing philosophical musings that border on pedantic. I’d guess that Picard has a Sagittarius Moon to back up his Capricorn energy. Plus, the signs of the zodiac tend to become more “abstract” in expression the further the move along the wheel (from Aries, the most primal force, to Pisces, the most diffused).

Anyway, here are some quotes that really speak to Crusher’s Taurus character:

“Perhaps it is a human failing; but we are not accustomed to these kinds of changes. I can’t keep up. How long will you have this host? What would the next one be? I can’t live with that kind of uncertainty. Perhaps, someday, our ability to love won’t be so limited.”

“If there is nothing wrong with me, maybe there’s something wrong with the universe!”

“Now, you be sure and dress warmly on those other planes of existence.”


The warrior archetype, fiery, independent, competitive, combative, and quick-tempered. Yep, Worf is Aries, the God of War. A one-track mind fixated on winning who would literally rather die than lose. His perception is black and white, something is or it isn’t, and his entire reality is filtered through the lense of the battlefield. You know those people who can only express things in metaphors related to their niche field of expertise? That’s Worf. Even love is a matter of conquest for him, which is a very Arien approach to love. He doesn’t really get complicated concepts like “nuance” or “table manners.”

He does have some Scorpionic tendencies to him as well, which also makes sense since the traditional ruler of Scorpio is also Mars. His bottling of emotions until they erupt into a raging volcano, for example. His prickly, asshole exterior, his obsession with death and weird rituals. He’s a Klingon so that’s part of the cultural package, but I think the point stands.

Some Worf quotes that show his Mars archetype:

“Klingons do not… pursue relationships. They conquer that which they desire.”

“If winning is not important, then Commander, why keep score?”

“Do not approach me unannounced—especially while I am eating.”

Deanna Troi

Troi is another one where race is going to factor in largely, as her whole thing is being an empath. Since she’s half human, she doesn’t have the full telepathic capabilities of a full-blood Betazoid, I guess. Or she just doesn’t “practice” enough on full-blown mind reading, as her mom has implied. It might even be that she’s intentionally handicapping herself because she gets so intoxicated with feelings that she doesn’t see a need to analyze the “left brain,” believing all there is to know is in the heart.

In any case, she pretty much feels other people’s feelings, and easily gets overwhelmed by strong emotions, because she’s just that special of a snowflake. I think you know where this is going: she’s Pisces. She’s bubbly, warm, idealistic, but also the most sexualized main character on the show (in her outfits compared to other characters, heavy makeup, overly stylized hair, and also by the fan base). For all the bad press Scorpio gets about being hyper-sexual, Pisces can sometimes get overlooked, but they do have some connection to sexuality as well. The 12th house in Vedic astrology is called the “house of bed pleasures.”

She also has an obsession with desserts, which I think is a stereotypical Pisces thing, indulging in sweets and other stuff that gives you a massive endorphin release but is actually toxic for you.

Some Deanna/Pisces quotes:

“It could provide us with valuable information about what’s troubling him. You know, there’s nothing wrong with a healthy fantasy life, as long as you don’t let it take over.”

“Look. He wouldn’t even talk to me unless I had a drink with him. And then, it took three shots of something called “tequila” just to find out that HE was the one we’re looking for! And I’ve spent the last twenty minutes trying to keep his hands off me! So don’t go criticizing my counseling techniques!”

“It unites humanity in a way no one ever thought possible. When they realize they’re not alone in the universe, poverty, disease, war – they’ll all be gone within the next fifty years.”

Geordi La Forge

Mercurial, very technical, and the most neurotic character on the show: Geordi is our Virgo archetype of the show. Always questioning and second-guessing everything (most of all himself), and always looking for ways to streamline or otherwise improve upon something. Geordi is the problem solver, but often becomes dominated by how anal-retentive he is. I’m pretty sure he complains more than any other character on the show. He is cerebral, and intelligent, no doubt about that, and the ruling planet of Mercury suits him pretty well. However, Mercury is the “lower mind” (with Uranus being the “higher mind”), and I think Geordi’s visor/being blind is a pretty good metaphor on his frequent blindness to matters of the higher mind (which in many cases have to be cryptically spelled out for him by Gainan). Also, leave it to Virgo to adopt an android as his best friend.

Geordi/Virgo quotes:

“I can’t help thinking how… or what else might have happened, all because I misspoke a single word.”

“See, it’s human nature to love what we don’t have. Simpler days, huh? Anyway, stringing this rigging has made me dream of handling sails…”

“Look, Mr. Scott, I’d love to explain everything to you, but the Captain wants this spectrographic analysis done by 1300 hours.”

Scotty: “Do you mind a little advice? Starfleet captains are like children. They want everything right now and they want it their way. But the secret is to give them only what they need, not what they want.”

Geordi: “Yeah, well, I told the Captain I’d have this analysis done in an hour.”

Scotty: “How long will it really take?”

Geordi: “An hour!”


I saved the fan favorite for last. In the beginning of this post I mentioned that another writer had listed Picard as an Aquarius. That same writer listed Data as a Capricorn. I guess because he is void of emotions? But I would flip those, and put Data as the archetypal Aquarius. The literal embodiment of the future and human progress. Freakishly intelligent on a cerebral level but severely emotionally handicapped. He tries to be creative but is lacking that basic element of humanity that would free him to move beyond perfect replications of pre-existing human creation. He literally has to learn to relate to humans slowly and painstakingly as a full grown adult. Sounds pretty Aquarius to me.

The thing is, like the Aquarius archetype, Data does have feelings, which are demonstrated in various episodes. They seem to be elusive to him, and he doesn’t really know how to effectively express them all the time. Much like a child, Data has to learn to recognize his own emotions and also learn how to express them and integrate them into his being. This is the final leap for Aquarius as well, represented in the zodiac wheel from moving from distant, cold Aquarius into the most deeply feeling Pisces.

Here are some Data/Aquarius quotes to end this post on:

“I would gladly risk feeling bad at times, if it also meant that I could taste my dessert.”

“I am attempting to fill a silent moment with non-relevant conversation.”

“There are still many human emotions I do not fully comprehend – anger, hatred, revenge. But I am not mystified by the desire to be loved – or the need for friendship. These are things I do understand.”

Pluto and the Astrology of Obsession

Plate 7- Pluto in a niche, holding a bident, with Cerberus next to him, from a series of mythological gods and goddesses

Topics covered in this post:

  • Aspects in your chart that would attract people who become obsessed with you (Plutonic people)
  • Plutonic synastry and the myth of “who feels it more”
  • Which natal chart aspects would show stalking behavior in someone’s chart, and which ones wouldn’t

Do you have a tendency to attract people who end up becoming obsessed with you? People who stalk you (in real life, on social media, asking your friends about you etc.), blow up your phone/DMs, try to play mind games with you, and seem to have a love/hate relationship with you? You might be a Plutonic person.

Meaning, you have very strong Pluto energy in your chart. What makes a strong Pluto? What makes any planet strong in a chart? The biggest factors are how many aspects it makes to personal planets/angles in your chart. Pluto in any aspect to the Sun/Moon/Ascendant/Mercury/Venus/Mars, gives Pluto some degree of power in the chart. The more aspects, the stronger the Pluto. Pluto conjunct an angle (Ascendant, Descendant, Midheaven, or Imum Coeli/Nadir) gives it a lot of strength in the chart. Also, personal planets (including chart ruler) in the 8th house or in Scorpio would also indicate a Plutonic person. Again, the more of this you have happening, the stronger your “Plutonic rating.”

Maybe you have a few of these aspects happening in your chart. What is it about Pluto that creates such a magnetic pull to you? If you’ve read my previous post, Pluto is a very dark energy. It shows where you’ve been through some intense transformative experiences in your life. Pluto is inherently very powerful in that it represents where in life you are torn down to absolutely nothing and reborn stronger. Pluto basically equates with power, and power is very attractive to many people. Pluto is the energy of success in the face of extreme adversity. He also embodies a darkness that is often attractive to people. Think of the popularity of anti-heroes and you’ve got a basic idea of the attraction of Pluto.

The Synastry of Pluto and the Myth of “Who Feels It More”

Goddess Proserpina (Queen of the Underworld)

By the law of attraction, if you have this Pluto energy happening in your chart, you have a good chance of attracting similarly intense people into your life. Obviously, not everyone you form any kind of relationship with (romantic, platonic, or otherwise) is going to become obsessed with you. This is where synastry comes into play. Plutonic people have a way of magnetizing to each other, so if you have a stalker or something similar, they probably have some Pluto demons to work out themselves.

But, if two people who are both Plutonic get together, does that equate to mutual stalking, power struggles, equal obsession on both sides? Not necessarily. I would look at the synastry between both Plutonic people and see how their Pluto configurations are interacting with each other’s charts. There always seems to be the looming question in synastry of “who feels what,” and “who feels it more.” To say it’s the Pluto person or the planet person who “feels it more” is an oversimplification. There is never going to be a definitive answer to that question that applies to every Venus/Pluto conjunction by synastry, every Moon/Pluto square, every Sun/Pluto sextile. You might have one relationship where your Venus conjuncts someone’s Pluto and they are the more fixated person, and then have another relationship with your Venus conjunct someone’s Pluto and you are the fixated one. And then a 3rd relationship with the same synastry aspect and neither of you develops an unhealthy obsession.

Not EVERY single guy/girl who has his/her Pluto conjunct your Venus is going to become addicted to you, or you to him/her. That would mean an entire generation of men/women would share that relationship dynamic with you, and that’s obviously not true for anyone. The same can be said for any other Pluto aspect in synastry. I would say it’s usually a combination of Pluto aspects that create toxic addiction between a couple. And the bottom line is when a relationships is decidely Plutonic, both people are going to feel it equally, in different ways. Both will be obsessed equally, but will express and act on it differently. And if it is to the extreme that this person is stalking you, it’s something in their own chart that would indicate they are prone to that behavior already, combined with something in your chart that they are specifically attracted to.

But which aspects would more likely indicate the type of person who would be a stalker? Is it really all Pluto?

Redon – Obsession, 1920

Not everyone who has a strong Pluto in their chart will get obsessed in their relationships to the point of stalking behavior, obviously. Because stalking behavior often accompanies some form of mental illness, there is usually a combination of a strong Pluto and other outer planets aspecting the inner planets. Studying some famous stalkers throughout history who have publicly available birthdays, the most frequent aspect I see in the charts of stalkers is Mars in aspect to Pluto, especially the trine. I expect hard aspects from Mars to Pluto could also apply, but might also suggest violence in addition to stalking. Mars/Pluto aspects make sense to me because Mars is your drive and ambition, your actions, and also sex drive, while Pluto is…well, Pluto. We’ve covered Pluto. Venus in aspect (especially soft) to Pluto also shows up in stalkers, and sometimes Mars conjunct Venus both in aspect Pluto. This also makes sense because Venus is what we want, our values, tastes, and love nature, and when combined with Mars by conjunction it can make a person who is persistent to the point of being pushy and insistent.

But like I said, in my limited research I also found that there are usually aspects from Neptune (hard or soft, but more often soft) to personal planets too, and also from Uranus to personal planets (hard or soft aspects). Neptune aspects make sense because they can show someone engaging in delusional thinking (which is typical of a stalker), and Uranus aspects because they can show general instability. Usually with Uranus and stalkers, it’s aspecting Mercury most often (mental instability), or the Moon (emotional instability), or sometimes Venus (unconventional and perhaps unstable views on love in general, a strange way of expressing love, an unstable love life).

Pluto aspects to the natal Sun, Moon, and/or Mercury do not generally seem to factor into stalking behavior, and other energies of Pluto more often come out with these.

Like the other outer planets, Pluto is karmic, and so by attracting these types of relationships into your life (whether you want to or not), you are working out some form of karma you’ve built up relating to themes of power, control, and intimacy. If you’re interested in checking out what kind of karma you have built up that might be causing this, or think you may be caught up in a karmic Plutonic relationship and want some insight, I would encourage you to purchase a Past Life reading or Synastry reading from my Services page.
