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.
