ISTP Enneagram Types: A Comprehensive Guide

The curious and freedom-loving ISTPs are one of the personality types you need more time to really get to know, as they have so many layers. Their complexity is easier to explain when we look at them through the lenses of the Enneagram theory. After all, that’s how nine distinct ISTP Enneagram subtypes were identified!

So, while the core ISTPs’ needs and traits remain the same regardless of their Enneagram subtype, the way in which this addition will pronounce them will vary. In this article, we’ll be talking about those subtle nuances that are not obvious at first sight but take time to be noticed.

A Quick Overview of the ISTP Personality Type

ISTPs are introverted people who rely on logic and reason when making decisions. They are very observant and detail-oriented, and the first thing you’ll notice about them is their personal freedom and independence, which play a large role in their lives.

These individuals feel frustrated by rules, so they tend to avoid them. More often than not, they are adventurers who like to experiment and are always open to trying new approaches rather than relying on tradition. Result-oriented and efficient, they can often be impatient and therefore prefer to commit to short-term projects rather than working on long-term ones.

Like all other thinking types, ISTPs are not particularly emotionally expressive. This is because they believe that deeds speak louder than words, and that’s their way of showing affection.

The Nine Enneagram Types of the ISTP

Now, isn’t it exciting to explore all the nuances of the ISTP character? Enneagram types add so many details to the regular nature of each personality type and are key to understanding why two ISTPs may behave in completely different ways. So, let’s take a closer look at all nine ISTP Enneagram variations.

#1. ISTP Enneagram Type 1

ISTP Enneagram Ones are more self-assured and energetic than typical ISTPs. They are also more focused, structured, and organized, unlike regular ISTPs, who like to keep their options open for as long as possible, contrasting with the typically adaptable and spontaneous ESFPs.

Moreover, because Type One is a perfectionist deeply concerned with doing things the right way, the natural ISTP’s tendency to experiment will be somewhat limited in this variation. Thanks to this, ISTP Ones are more likely to stick to the rules.

Additionally, the One’s need for change takes a very concrete form, which is why ISTP Enneagram Ones are usually pragmatic people who don’t waste time on unattainable ideals.

Both Ones and ISTPs are introverted, so it’s no wonder ISTP Enneagram Ones are typically lone wolves. They connect with other people through work and intellectual conversations and need a long time to warm up to someone, but when they do, they are loyal and committed.

Their core fear is that unless they are perfectly competent, they may be seen as flawed, so they strive hard to perfect their many skills. What they want is a life of purpose, full of interesting experiences.

#2. ISTP Enneagram Type 2

The combination of ISTP and Enneagram Type 2 is very atypical. The soft, emotional Twos are all about catering to other people’s needs, and their whole world revolves around making their loved ones happy. Meanwhile, ISTPs are all about independence and adventure.

So, when these two types fuse into one person, the result is an individual who is much more invested in their relationships than a regular ISTP. The natural ISTP’s curiosity is often more directed toward understanding human psychology and the logic of emotions.

The Twos’ need to help others and the ISTPs’ need to be practical result in a person who is genuinely kind and likes to help others enhance their skills and gain knowledge. Needless to say, this kindness and devotion also apply to their personal relationships, which is why they make great and caring friends and partners.

Finally, ISTP Enneagram Twos are hardworking, meticulous people who believe they have to earn the respect and love of other people by being useful. Therefore, their deepest fear is that unless they can help others, they will be abandoned. As for their desires, they are not as concerned with adventure as regular ISTPs but desire a more peaceful life.

#3. ISTP Enneagram Type 3

ISTP Enneagram Threes are more energetic and ambitious versions of ISTPs. They are also better organized and more result-oriented, which is why they are commonly mistaken for ISTJs. Success plays an important role in their lives, but they are not flashy or image-conscious like typical Threes.

These ISTPs are also more determined to follow their own interests and are more persistent in following through. They are often great experts in their field of work but can be very detached in personal relationships, as both Threes and ISTPs have trouble staying in touch with their feelings.

Additionally, ISTP Enneagram Threes are very hardworking, and they love to keep themselves busy. This is because they have a tendency to feel worthy only if they are diligent and successful, so they place a lot of importance on prosperity in their lives.

Fear of being a failure haunts them chronically and pushes them to work hard even when they feel like quitting. They dream of an adventurous life in which they enjoy the respect and love of other people because of who they are and not for what they succeed in.

#4. ISTP Enneagram Type 4

ISTP Enneagram Fours like adventure and see it as a quest for self-discovery. They easily get bored unless they are constantly learning new things, but the good thing is that they easily find inspiration in everyday life even when such things happen. That’s because these ISTPs are more imaginative than regular ISTPs and often have a strong artistic streak.

Even when they are not particularly artistic, ISTP Fours show unique creativity and like to fix things with their hands. Deep down, they often feel there’s something wrong with them, which may be one of the reasons why they feel such a strong urge to fix broken or malfunctioning items—it provides them with a kind of catharsis.

ISTP Enneagram Fours are also uniquely observant. They notice many curious details about other people’s behavior and take time to examine their conclusions and learn about human nature. This is also how they explore their own identities.

The biggest fear of the ISTP Enneagram Type Four is failing to let the world know who they are. Meanwhile, their deepest desire is to explore their passions and identities free from outside pressure.

#5. ISTP Enneagram Type 5

ISTP Enneagram Fives are the most typical ISTPs of all Enneagram types, so all the characteristic traits of both Fives and ISTPs are very pronounced. These people are committed to learning and understanding life to the core—they enjoy solving logical puzzles, discovering new things, and simply making sense of the world and life.

Their analytical and critical thinking abilities are also rather developed, and they have no trouble seeing any issue from multiple viewpoints. They carefully plan every move they make and make decisions only after they’ve considered every possible detail about the issue at hand. Due to this, other people often consider them too detached and calculated.

These ISTPs may be highly introverted and independent and may avoid making any close relationships. One of the reasons for such behavior is their core fear of being dependent on others. Therefore, they invest significant efforts to satisfy their deep desire for complete autonomy by acquiring many different skills and knowledge.

#6. ISTP Enneagram Type 6

These ISTPs are also one of the less typical representatives of the type. However, since Sixes are one of the most anxious and fearful Enneatypes, they will be more cautious and insecure than regular ISTPs. They will also be less independent and more likely to seek security in the outside world.

The ISTPs’ adventurous spirit is shadowed by the chronic fear of Type Six, who needs to plan everything and ensure they do not expose themselves to any risk. For that reason, ISTP Sixes may show some kind of intellectual adventurism, but they will not have the typical ISTP’s thirst for exciting experiences.

Secretly, while ensuring their families are safe and happy, these people dream of adventures, which they replace with intellectual curiosity. For that reason, they may sometimes be mistaken for INTPs. As for their fears, they dread the idea of being cut off from the community and their social circle.

#7. ISTP Enneagram Type 7

ISTP Enneagram Sevens are passionate adventurers, always seeking novelty and excitement. These ISTPs have a strongly pronounced hedonistic tendency and are generally more lively, energetic, and outgoing than regular ISTPs. Still, even though they are more sociable, they still have all the typical ISTP difficulties when it comes to expressing deeper emotions.

These ISTPs make connections easily, but they are not particularly steady either as friends or partners. That’s because they dread unpleasant emotions and feel a deep urge to run away from any (even slightly) conflicting situation.

They dream about living exciting lives in which they would be free to pursue all their passions with sheer enthusiasm. Yet, even if they can’t have that kind of life, they fill their days with fun, pleasure, and interesting activities, and people often find them very joyful to be around.

Idealistic, energetic, and curious, these ISTPs may often be confused with INTPs, because of their tendency for abstract thinking and focus on the future. Their lively approach to life and avoidance of deeper emotional entanglements are humorously portrayed in our Enneagram 7 memes compilation.

#8. ISTP Enneagram Type 8

ISTPs and Eights both rely on their logic and are reality-oriented. However, Eights are more focused, power-hungry, and always up to fight for justice, while ISTP’s approach to life is more relaxed. Therefore, this variation of ISTPs will be more energetic, driven, and goal-oriented than typical ones.

ISTP Enneagram Eights also enjoy good discussions and never miss the opportunity to point out illogical or flawed ideas, which is why they are sometimes perceived as insensitive. They often lack the emotional and social intelligence to see that by fighting the wrong battles, which sometimes makes them lose friends while winning pointless arguments.

Since Eights value their autonomy the most and ISTPs are also very independent, ISTP Eights' deepest fears usually revolve around losing their independence and having to rely on other people. On the other hand, their strongest desire is to have control over their lives and avoid being vulnerable.

#9. ISTP Enneagram Type 9

ISTP Enneagram Nines are kind and deeply loving individuals who, despite not showing much affection, make other people feel good. That’s because they don’t judge anyone—they just accept people with all their flaws and virtues without any expectation, so others are relaxed and open around them.

These ISTPs are particularly sensitive to conflict and tend to avoid it whenever possible. They see the issues from multiple viewpoints and identify easily with other people’s needs, which makes it very hard for them to make decisions and choose sides, despite their objectivity.

Quiet and gentle, these people balance the atmosphere wherever they show up. The ISTPs' need for adventure is expressed as daydreaming and rich imagination in this type, so these people are often inclined to art.

Finally, ISTP Enneagram Nines often feel like there’s a chance other people would reject them unless they made sure there were no conflicts. Their biggest fear is having to choose sides and being unable to soothe conflicts. And logically, what they wish for most is a happy, peaceful, and stable life.

The Most and Least Common ISTP Enneagram Types

Although it makes sense that ISTPs are more likely to identify with logical, reality-focused Enneagram types, you might be surprised at the proportion of ISTPs who identify as Nines and Sevens. So, we’re sharing here some general facts about the most probable ESTP Enneagram correlations (even though nothing is written in stone).

Most Common ISTP Enneagram Types

The most common ISTP Enneagram types are Fives, Nines, Sixes, and Sevens. Fives dominate the statistics, which comes as no surprise since ISTPs and Fives have so many characteristics in common.

Nines are less common but make up a significant proportion of ISTPs, which is largely due to the shared introverted feeling characteristic. Sixes and Sevens are also not so rare, but they are more of an exception to the rule than the rule itself.

Least Common ISTP Enneagram Types

The least common ISTP Enneagram types are Threes, Fours, and Eights. The introverted, introspective, and kind ISTPs don’t have the drive of the Threes, the moodiness of the Fours, or the hunger for power of the Eights, so these are really extremely rare correlations.

Conclusion

In most cases, the INTPs’ generally balanced character blends well with correlating Enneagram types. Combinations with Enneagram feeling types may cause ISTPs to be more similar to INFPs, while combinations with more result-oriented types may make them more similar to INTJs.

So, the bottom line is that Fives, Nines, Sixes, and Sevens are the most common among INTPs, which is very interesting as apart from Five, these types are not too similar to INTPs in general. Meanwhile, Threes, Fours, and Eights make up the smallest proportion of INTPs, and that makes perfect sense knowing how freedom-loving, detached, open-minded, and subtle they are in essence.
