The most common ISTP Enneagram type is Type 9, followed by Type 5 and Type 6. That means many ISTPs look calm, self-contained, and conflict-avoidant rather than intensely forceful or visibly competitive. The Enneagram explains why the same Ti-Se personality can appear as a quiet peacemaker, a detached investigator, or a cautious problem-solver.
The ISTP is one of the most self-contained personalities in the MBTI framework — observant, technically precise, and deeply oriented toward understanding how things actually work. Yet two people who both identify as ISTP can seem strikingly different from each other. One is the calm, detached analyst who disappears into complex problems and surfaces only when the solution is ready. Another is an easygoing, undemanding presence who moves through the world with quiet adaptability and a preference for keeping things undisturbed. A third is a driven, self-reliant operator who builds expertise with deliberate intensity and guards their independence fiercely.
This guide compares all nine ISTP-Enneagram combinations, starting with the most common patterns and then moving into the rarer pairings.
A large-scale study of over 136,000 participants mapped how Enneagram types distribute across MBTI profiles. Among ISTPs, the results were striking: Type 9 is the most common, appearing in 37.3% of ISTPs — a remarkably high concentration for a single type. Type 5 follows at 18.6%, and Type 6 at 15.0%. Together, these three types account for more than 70% of all ISTPs.
This article covers all nine ISTP-Enneagram combinations in detail: what each looks like in practice, how the ISTP's cognitive functions interact with each Enneagram motivation, and what distinguishes the rare pairings from the common ones.
How MBTI and the Enneagram Work Together
Before examining specific combinations, it helps to understand what each system contributes.
MBTI describes how a person processes information and makes decisions. ISTPs lead with Introverted Thinking (Ti) — a function that analyzes by constructing internal logical frameworks, taking things apart to understand the underlying mechanics. Ti is not primarily concerned with external validation or group consensus; it wants to know how things actually function, and it evaluates that independently. When something does not make sense to the ISTP's internal logic, it does not matter how many authorities have endorsed it.
The secondary function is Extraverted Sensing (Se) — a function that engages directly and immediately with the concrete physical world. Se keeps the ISTP grounded in present-moment reality: what is actually happening, what is physically present, what can be directly tested or observed. It gives ISTPs their characteristic comfort with hands-on engagement and their often remarkable situational awareness.
Together, Ti and Se produce a person who learns by doing, thinks in systems, and operates with a kind of cool, practical precision. They trust what they can verify through direct engagement and careful analysis. They are skeptical of abstractions that cannot be tested and of rules that cannot be justified on their own merits.
The Enneagram describes why a person acts. It maps nine core motivational structures, each rooted in a deep desire and a corresponding fear. The same Ti-Se cognitive machinery produces very different behavior depending on whether the underlying motivation is the fear of conflict and separation (Type 9), the fear of incompetence (Type 5), or the fear of being without support (Type 6).
Importantly, the Enneagram does not replace or contradict MBTI. It does not give the ISTP new cognitive tools. It directs the existing tools — Ti's independent analysis and Se's concrete engagement — toward different ends, and it shapes the particular flavor of how the ISTP's detachment, precision, and self-reliance express themselves.
The Distribution: Most Common Enneagram Type for ISTP
Based on the 136,000-person study, here is the full distribution of Enneagram types among ISTPs:
| Enneagram Type | % of ISTPs |
|---|---|
| Type 9 (The Peacemaker) | 37.3% |
| Type 5 (The Investigator) | 18.6% |
| Type 6 (The Loyalist) | 15.0% |
| Type 8 (The Challenger) | ~10–11% |
| Type 1 (The Perfectionist) | ~6–7% |
| Type 7 (The Enthusiast) | ~4–5% |
| Type 4 (The Individualist) | ~3–4% |
| Type 3 (The Achiever) | ~2–3% |
| Type 2 (The Helper) | ~1–2% |
Type 9's dominance is worth pausing on. More than one in three ISTPs identifies with the Type 9 motivational structure — a finding that, once understood, is deeply coherent. The overlap between Ti-Se's detached, low-friction engagement with the world and Type 9's peace-seeking, non-intrusive orientation is not coincidental. It represents a natural alignment at the deepest motivational level.
ISTP Enneagram Type 9: The Detached Peacemaker
Prevalence: ~37% of ISTPs
Type 9 is the single most common Enneagram type among ISTPs by a significant margin, and the alignment between the two profiles is both immediate and deep once you see it.
Type 9's core fear is conflict and disconnection — being at odds with others, with the world, or with one's own inner equilibrium. The response is a kind of strategic non-interference: avoiding friction, accommodating what is present, maintaining peace, and often setting aside personal preferences to keep things undisturbed. Type 9s are oriented toward merging with their environment rather than imposing themselves on it.
Introverted Thinking is a natural partner to this motivation in a specific way that is easy to misread. Ti does its work internally, quietly, without needing to announce conclusions or impose frameworks on others. It analyzes independently, but it does not characteristically demand that others conform to its analysis. The ISTP-9 thinks carefully and often incisively, but holds those conclusions with a kind of relaxed detachment — they do not feel urgently compelled to correct others or defend their position unless something genuinely important is at stake.
Extraverted Sensing amplifies this. Se is present and responsive in the moment, engaging with what is directly at hand rather than projecting into the future or dwelling in the past. For the ISTP-9, this produces a person who is genuinely easy to be around: calm, observant, unhurried, and naturally attuned to the immediate environment without being reactive to it. They do not introduce unnecessary complexity. They do not generate drama.
In practice: The ISTP-9 is often the most undemanding person in the room. They adapt to circumstances with an ease that others find striking, moving through varied environments and social contexts without needing things to be a particular way. They are the colleague who does solid, reliable work without creating friction, the friend who is there without requiring constant attention, the partner who accommodates without apparent difficulty.
Their inner analytical life is often richer than it appears from the outside. The ISTP-9's Ti is working steadily — processing, assessing, building understanding — but the Type 9 overlay keeps much of this internal. They rarely volunteer opinions unless asked, not because they lack them, but because the motivation to share does not feel urgent enough to disrupt the equilibrium.
The ISTP-9 tends to have clear practical preferences — in how things are built, in how problems are approached, in what constitutes a well-functioning system — but they often hold these preferences quietly. They will implement what they consider the better solution if given latitude, but they will not fight for that latitude or advocate loudly for their approach against resistance.
At their best: ISTP-9s are the most grounded and adaptable ISTP subtype. Their calm under pressure is not forced composure — it is genuine. Ti's ability to analyze without emotional distortion and Type 9's peace-seeking orientation combine to produce someone who remains functional and clear-headed in situations that destabilize others. They are often the stabilizing presence in high-stress environments, not through active leadership but through an absence of reactivity that allows others to settle.
Their technical ability is real and typically underestimated, because it is offered without performance. The ISTP-9 does not present their competence; they simply apply it, quietly and effectively.
Growth edge: The ISTP-9's greatest challenge is the same one that faces all Type 9s: the tendency to merge with the environment at the cost of their own direction and expression. Ti generates real assessments and real preferences; Type 9's peace-seeking can suppress them so consistently that the ISTP-9 loses clarity on what they actually want, not just what they are willing to accept.
This is compounded by Se's in-the-moment orientation. Without a strong future focus or a pressing motivation to assert direction, the ISTP-9 can move through life in a reactive rather than self-directed way — responding to what arises, accommodating what is present, but never quite taking the initiative to point toward something they genuinely want. The growth path involves recognizing that expressing what they know, what they prefer, and what they need does not constitute aggression. It constitutes self-presence — and ultimately, the people around them benefit from having access to the ISTP-9's actual perspective.
Common wings: 9w8 ISTPs are more self-contained and quietly assertive, with the Type 8 wing adding a current of independence and directness that occasionally surfaces with unexpected force. 9w1 ISTPs are more internally principled and attentive to quality, holding quiet standards that they may not express but that shape how they evaluate their own work.
ISTP Enneagram Type 5: The Analytical Craftsman
Prevalence: ~19% of ISTPs
Type 5 is the second most common Enneagram type among ISTPs, and the combination is immediately intuitive once you understand both profiles. It represents one of the most internally coherent ISTP subtypes.
Type 5's core fear is incompetence — being caught without the knowledge, skill, or internal resources to handle what the world demands. The response is a deep investment in accumulation: build expertise, conserve energy, maintain independence, and never engage a domain until it is understood thoroughly enough to feel secure. Type 5s withdraw from the world to observe and analyze it, returning to engage only when they feel adequately equipped.
Introverted Thinking is an almost ideal partner for this motivation. Ti is fundamentally an analytical function — it takes systems apart to understand how they work, builds internal models of causation and structure, and finds genuine satisfaction in mastering the logic of a domain. The ISTP-5 does not just fix or build things; they understand why the fix works, why the design functions as it does, why the system behaves in that particular way under those particular conditions. Their expertise is not just operational — it is architectural.
Extraverted Sensing grounds this in the concrete. Unlike a pure Type 5 who might remain entirely theoretical, the ISTP-5 is pulled back into direct physical engagement by Se's orientation toward what is present and testable. Their understanding is built through hands-on experimentation, not just through study. They learn by taking things apart, by testing hypotheses against real conditions, by observing what actually happens rather than what theory predicts should happen.
In practice: The ISTP-5 is typically the most deliberately private and self-contained ISTP subtype. They tend to have a relatively narrow circle of trusted contacts and a wide expanse of independent activity. They are often deep specialists — the person who knows their domain in unusual depth and breadth, not because anyone required it of them but because they find the process of mastery genuinely satisfying.
They are careful about how they spend their energy and often very deliberate about what they engage with. They do not typically involve themselves in social dynamics, organizational politics, or activities that do not offer either practical utility or genuine intellectual interest. This can read as cold or disinterested to people who do not know them well; it is more accurately a kind of efficiency — they are deeply engaged where it matters to them, and genuinely indifferent elsewhere.
The ISTP-5 often has a precise, measured quality in how they communicate. They say what they know, with appropriate qualification, and stop. They are genuinely comfortable with silence and do not experience the absence of conversation as a problem to be solved.
At their best: ISTP-5s are exceptional technical specialists who combine Ti's systematic understanding with Type 5's drive for thorough mastery and Se's direct experimental engagement. In their chosen domains, they often reach levels of knowledge and skill that appear effortless from the outside, because the drive to understand is so intrinsic that the accumulation of expertise happens naturally rather than through forced effort.
Their work tends to be precise, well-reasoned, and genuinely well-made. The ISTP-5 does not cut corners on things they care about, because cutting corners would mean accepting a gap in their understanding — and that is something Type 5 finds genuinely difficult to tolerate.
Growth edge: The ISTP-5's drive for preparedness before engagement can become a form of indefinite deferral. Ti's thoroughness and Type 5's caution reinforce each other into a loop in which more analysis is always needed before acting, more expertise is always required before feeling adequate, more observation is always justified before committing. Real mastery comes partly from doing, from encountering the ways a real system deviates from the model, and the ISTP-5 sometimes needs to engage before feeling fully ready.
There is also a risk of using private expertise as a substitute for connection. The ISTP-5's competence is real, but keeping it largely internal — demonstrating it only in domains they control — can leave a genuine isolation that is felt more than acknowledged.
ISTP Enneagram Type 6: The Vigilant Technician
Prevalence: ~15% of ISTPs
Type 6's core fear is being without support, guidance, or security in a world that is fundamentally uncertain and potentially threatening. The response is vigilance: scanning for what could go wrong, building reliable frameworks, and forming bonds of loyalty with people, systems, or institutions that can be trusted.
The ISTP-6 is a somewhat less common subtype but a highly coherent one. Ti's independent analysis provides a natural tool for the Type 6 project of assessing reliability: the ISTP-6 uses their analytical capacity to test what they can actually depend on, looking for logical consistency and practical reliability rather than social reassurance. They extend trust to systems and people that have demonstrated genuine competence — not to those who simply claim it.
Se keeps this grounded in what is directly observable. The ISTP-6 does not trust abstractions or promises; they trust demonstrated performance and concrete evidence. Their vigilance is not free-floating anxiety but practical risk assessment: identifying the specific failure modes, the specific vulnerabilities, the specific ways a system or a person could let them down.
In practice: The ISTP-6 is more alert to potential problems than other ISTP subtypes. They often maintain contingency thinking as a background process — not catastrophizing, but running quiet checks on what could go wrong and whether they have covered it. This can make them unusually thorough in technical work, because they naturally ask "what happens if this fails?" at each step.
They tend to be loyal and reliable within their trusted circle, and considerably more guarded outside it. Once the ISTP-6 has tested and verified someone as trustworthy, that relationship is durable. Before verification, they maintain a careful distance that can be mistaken for coolness.
At their best: ISTP-6s are exceptional at identifying the points where systems or plans are genuinely vulnerable. Their combination of Ti's structural analysis with Type 6's vigilance produces a kind of practical risk intelligence — not pessimism, but a well-calibrated awareness of where actual failure is likely. They often prevent problems that others, more confident and less careful, would have introduced.
Growth edge: The ISTP-6's scanning for threats can become habitual rather than responsive — running as a background process even in low-risk environments where it consumes energy without providing genuine protection. The ISTP's natural independence (Ti-Se does not require external guidance) can conflict with Type 6's dependence on external structures for security, creating a tension between trusting their own judgment and needing external confirmation. The development path involves learning to extend trust — to their own analysis, to people who have earned it, and to situations that do not yet have enough data to fully evaluate.
ISTP Enneagram Type 8: The Autonomous Operator
Prevalence: ~10–11% of ISTPs
Type 8's core fear is vulnerability — being controlled, harmed, or made dependent on others. The response is a drive for strength, autonomy, and the power to determine one's own circumstances without being subject to others' authority.
The ISTP-8 is the most assertive and overtly self-directed ISTP subtype. Ti's independent logic aligns naturally with Type 8's resistance to external authority: the ISTP-8 does not accept constraints they cannot justify on their own terms, and they have a clear internal sense of the boundary between what is legitimately others' business and what is not. Se's direct engagement with immediate reality gives this conviction a grounded, practical quality — the ISTP-8 is not just abstractly autonomous; they are concretely capable of functioning independently, which makes their self-reliance feel earned rather than merely asserted.
In practice: The ISTP-8 is harder-edged and more openly direct than other ISTP subtypes. They are the ISTP most likely to push back explicitly against what they see as unnecessary constraint, bureaucratic waste, or incompetent authority. They are also the ISTP most likely to take decisive unilateral action when they have assessed a situation and know what needs to happen — they do not wait for consensus or permission.
Their competence is often genuine and substantial, and they tend to respect competence in others, creating small, trusted circles of people they consider worth working with. Outside that circle, they maintain significant independence.
Growth edge: The ISTP-8's directness can damage relationships and generate resistance that makes genuine collaboration harder than it needs to be. Ti's internal logic does not always account for the relational costs of how conclusions are expressed, and Type 8's push against vulnerability can prevent the ISTP-8 from acknowledging genuine uncertainty or asking for input when it would actually be useful. The development path involves recognizing that accepting help, acknowledging limits, and working with rather than around others is not capitulation but genuine strategic intelligence.
ISTP Enneagram Type 1: The Precise Craftsperson
Prevalence: ~6–7% of ISTPs
Type 1's core fear is being wrong, flawed, or corrupt — falling short of the internal standard of correctness that defines their sense of integrity. The response is an internalized critic that evaluates every output against an exacting standard, driven by a genuine felt obligation to do things right.
The ISTP-1 is a somewhat unusual combination because Ti and Type 1 both care about correctness, but from different angles. Ti cares about logical coherence — whether the system works as it should, whether the analysis is valid. Type 1 cares about moral and qualitative rightness — whether the work meets the standard of how it should be done. The ISTP-1 carries both, which can produce exceptional precision but also an internal critic that is difficult to satisfy.
In practice: The ISTP-1 is the most detail-oriented and self-critical ISTP subtype. They hold high standards for their own work, notice errors that others overlook, and can be genuinely uncomfortable with imprecision or carelessness. Their Type 1 orientation gives their Ti analysis a particular quality of judgment: it is not just about whether something works, but about whether it is done well.
Growth edge: Ti already drives the ISTP toward precision; Type 1's internalized critic amplifies this into pressure that can become difficult to sustain. The ISTP-1 sometimes needs to distinguish between the genuine standard — what Ti knows is actually important — and the perfectionist layer that applies the same level of scrutiny regardless of what is actually at stake.
ISTP Enneagram Type 7: The Exploratory Tinkerer
Prevalence: ~4–5% of ISTPs
Type 7's core fear is being trapped — in pain, limitation, boredom, or any situation that forecloses future possibility. The response is an expansive orientation: staying mobile, generating options, pursuing stimulation, and maintaining access to new experiences.
The ISTP-7 is a vivid and energetic combination. Se's orientation toward immediate concrete experience aligns naturally with Type 7's appetite for what is new, interesting, and directly engaging. Ti's drive to understand systems is directed by Type 7 toward a wide range of domains rather than deep mastery of a few. The result is someone who picks things up quickly, engages enthusiastically with the mechanics of new domains, and moves to the next thing with relatively low friction.
In practice: The ISTP-7 is the most outwardly energetic and variety-seeking ISTP subtype. They tend to be more openly enthusiastic, more willing to try new approaches, and more explicitly interested in experiences that push against boundaries. They are often highly engaging to talk with, because their Ti has touched a wide range of domains and Se keeps them grounded in concrete, specific detail.
Growth edge: The ISTP-7's appetite for novelty can work against the depth of engagement that Ti needs to fully develop mastery. Ti's strength comes from sustained analysis — from following the logic of a system all the way down rather than moving on when the surface mechanics are understood. The development path involves tolerating the less stimulating phases of deep expertise in order to arrive at the understanding that only sustained engagement produces.
ISTP Enneagram Type 4: The Unconventional Analyst
Prevalence: ~3–4% of ISTPs
Type 4's core fear is being ordinary — lacking the depth, significance, or authentic identity that would make one's existence genuinely meaningful. The response is an ongoing inward search: discovering and expressing what is personally unique, refusing easy conformity, and finding meaning through depth of experience.
The ISTP-4 carries an interesting internal tension. Ti operates by internal logic that is inherently personal and independent — it reaches its own conclusions regardless of what is conventional — which gives it a natural overlap with Type 4's rejection of the generic. At the same time, Se is oriented toward concrete present engagement, which can pull against Type 4's tendency toward introspection and longing for what is absent.
In practice: The ISTP-4 is more emotionally aware and more drawn to aesthetic and personal dimensions of experience than other ISTP subtypes. They may bring a quality of personal investment to their technical work that other ISTPs do not — caring not just that the solution works but that it has a particular character or integrity. They tend to be more aware of their inner world and more willing to acknowledge complexity in how they feel about situations.
Growth edge: Type 4's tendency toward melancholy and a sense of what is missing can sit uneasily with Se's orientation toward present engagement. The ISTP-4 can find themselves caught between genuine presence in the moment and a longing for some deeper meaning or significance that the immediate experience does not provide. The development path involves recognizing that the ordinary does not preclude depth — that Ti's engagement with the mechanics of concrete things can be genuinely meaningful, not just a substitute for something better.
ISTP Enneagram Type 3: The Driven Performer
Prevalence: ~2–3% of ISTPs
Type 3's core fear is worthlessness — being seen as a failure, lacking value, or producing work that does not demonstrate genuine competence. The response is achievement: setting goals, delivering results, and maintaining an image of capability.
The ISTP-3 is a relatively rare combination that introduces genuine tension between the ISTP's characteristic detachment and Type 3's orientation toward external recognition. Ti is not naturally oriented toward others' assessments — it evaluates by its own internal standard, not by the response it receives. Type 3 cares deeply about how competence is perceived, which can create pressure to optimize for legibility and recognition in ways that Ti's internal logic does not naturally support.
In practice: The ISTP-3 is more outwardly ambitious and more explicitly results-oriented than other ISTP subtypes. They care about delivering work that is visibly effective, and they invest real energy in making their competence apparent. They tend to be more engaged in professional environments that reward demonstrated achievement and more motivated by concrete, measurable goals.
Growth edge: The ISTP-3's drive for recognition can lead them to optimize for outcomes that look impressive rather than for the genuine technical excellence that Ti is capable of. The development path involves trusting that the internal standard Ti knows to be valid is more worth pursuing than the external acknowledgment Type 3 seeks — and that authentic competence, pursued on its own terms, ultimately produces more durable results.
ISTP Enneagram Type 2: The Practical Supporter
Prevalence: ~1–2% of ISTPs
Type 2's core fear is being unloved or unwanted. The response is a focus on others' needs — being attentive, helpful, and present in ways that create genuine connection and earn a place in others' lives.
The ISTP-2 is the rarest and most internally complex ISTP combination. Ti is fundamentally inward-oriented — it works by independent analysis and is not naturally other-referential. Se engages with the immediate environment but primarily in service of understanding and effectiveness, not connection. Type 2's orientation toward others' emotional needs and toward relational bonds introduces a motivational dimension that is genuinely foreign to the baseline ISTP cognitive structure.
In practice: The ISTP-2 is the warmest and most relationally engaged ISTP subtype. They show care not through emotional expressiveness but through practical action: noticing what someone needs, applying their technical capability in service of others, being the person who fixes the problem without being asked. Their help is concrete and real, even when it is not verbally effusive.
The tension between Ti's independence and Type 2's relational orientation can create genuine internal conflict. The ISTP-2 sometimes finds themselves caught between a deep preference for autonomous action and an equally genuine desire to be valued and needed by the people they care about.
Growth edge: Type 2 tends to suppress its own needs in favor of relational bonds. For the ISTP-2, this can compound with Ti's already inward orientation to produce someone who provides reliable practical support while rarely acknowledging what they themselves need. The development path involves recognizing that expressing their own needs and preferences does not undermine the connections they value — it makes those connections more genuine.
How Ti-Se Shapes Every Combination
The ISTP's cognitive stack — Ti, Se, Ni, Fe — provides the architecture. The Enneagram provides the motivational direction running through it.
Ti (Introverted Thinking) builds independent internal models of how things work, evaluating by internal logical consistency rather than external authority. In a Type 9, Ti works quietly without urgency to impose its conclusions. In a Type 5, Ti becomes the engine of deep expertise and the source of security through mastery. In a Type 8, Ti provides the basis for self-reliance and resistance to external authority. In a Type 1, Ti is amplified by an internal critic that holds its analysis to a demanding standard of correctness.
Se (Extraverted Sensing) engages directly with the concrete present environment, providing immediate situational awareness and a natural orientation toward hands-on engagement. In a Type 9, Se supports a low-friction, accommodating presence in the immediate environment. In a Type 7, Se is amplified into an active appetite for new sensory and experiential engagement. In a Type 6, Se grounds vigilance in concrete observable data rather than abstract threat.
Ni (Introverted Intuition) — the tertiary function — provides glimpses of future-oriented pattern recognition that the ISTP accesses intermittently. The Enneagram type shapes how developed this function becomes: Type 5 ISTPs often develop Ni more consciously as part of their systematic analysis; Type 9 ISTPs may engage it in service of anticipating and avoiding future disruption to equilibrium.
Fe (Extraverted Feeling) — the inferior function — is the ISTP's least developed axis, carrying awareness of social harmony and others' emotional states that surfaces primarily under stress or in moments of genuine connection. Type 2 and Type 9 ISTPs tend to be more consciously aware of this function; Type 5 and Type 8 ISTPs typically keep it in the background, engaging it only in specific trusted contexts.
Understanding your Enneagram type as an ISTP does not change your cognitive architecture. But it explains why your Ti-Se engine is pointed in the direction it is — and what it would take to direct it more intentionally.
Identifying Your Own Combination
If you know you are an ISTP but are uncertain about your Enneagram type, the most direct question is not "which behaviors do I recognize?" but "which fear do I recognize?"
- If you are most afraid of conflict, disconnection, or losing inner equilibrium: Type 9.
- If you are most afraid of being incompetent or without the knowledge and skill to handle what is demanded: Type 5.
- If you are most afraid of being without support, guidance, or a reliable structure in an uncertain world: Type 6.
- If you are most afraid of being controlled, harmed, or made dependent on others: Type 8.
- If you are most afraid of being wrong, flawed, or falling short of the standard of correctness: Type 1.
- If you are most afraid of being trapped in pain, limitation, or boredom: Type 7.
- If you are most afraid of being ordinary or without genuine depth and authentic identity: Type 4.
- If you are most afraid of failing or being seen as worthless: Type 3.
- If you are most afraid of being unloved or unwanted: Type 2.
The distribution data makes a useful heuristic for the most common types. If you are an ISTP uncertain between Type 9 and Type 5, pay attention to the direction of the concern: Type 9 is primarily oriented toward maintaining peace and avoiding disruption — the fear is of conflict and fragmentation. Type 5 is primarily oriented toward building adequate knowledge and capability before engaging — the fear is of being caught without sufficient resources. Both can appear withdrawn and self-contained, but the underlying driver is different in character.
If you are uncertain between Type 9 and Type 6, note that Type 9's peace-seeking tends to minimize problems and maintain equilibrium, while Type 6's vigilance actively looks for what could go wrong. The Type 9 ISTP is calm; the Type 6 ISTP is careful.
