In short
The instinctual variants are three survival drives — self-preservation, social, and sexual (one-to-one) — that each of us runs in a personal order. Layered over the nine types they produce the 27 “subtypes.” It is a rich traditional lens; the evidence behind it is thin, and The Crossing does not score it — it types you, then hands you the instincts to place yourself in.
The model
The three instincts
Beneath your type, the tradition says, run three ancient survival drives. Everyone has all three, but they line up in an order — one leads, one supports, one gets neglected — and the leader colors how your type shows up day to day.
| Instinct | What it watches | When it leads, you |
|---|---|---|
| Self-preservation (sp) | Safety, comfort, health, money, routine — the body and its resources | Manage the practical baseline first; you notice temperature, budget, and energy before most people do |
| Social (so) | Belonging, the group, status, reading the room, contribution | Track where you stand and how the group is doing; you feel responsible to and for the collective |
| Sexual / one-to-one (sx) | Intensity, chemistry, attraction, the charged one-on-one bond | Go straight for depth and heat; you'd rather have one electric connection than a room of pleasant ones |
A note on the names: “sexual” here means the drive toward intense one-to-one bonding, not literally sex — many teachers now call it the one-to-one instinct for exactly that reason. Your leading instinct is not better or worse than the others; it is just where your attention goes first when you are not thinking about it.
Not sure which one is you? 10–12 minutes — and you'll know how sure to be.
Take the Enneagram Test →The subtypes
The 27 subtypes — and the countertype
Multiply the nine types by the three instincts and you get 27 combinations — the “instinctual subtypes.” The idea is that your dominant instinct bends your type’s core motivation toward one arena: the self-preservation Six worries about security in practical, household terms; the social Six about loyalty to the group; the one-to-one Six about trust and intensity with a chosen few.
Traditional theory: within each type, one of the three subtypes is the countertype — the one that looks least like the type, because its instinct pushes against the type’s usual style. The self-preservation Four, for instance, reads as tougher and more self-reliant than the expressive, longing Four most descriptions paint. The countertype idea is where the subtype lens earns its keep: it explains people who are “clearly” a type in their motivation while looking nothing like the stereotype.
Our interpretation: this is also where subtypes cause the most mistyping. A vivid subtype presentation can pull you toward the wrong core type — you recognize the behavior of a look-alike and miss the motive that would place you correctly. If two types feel close, read them on a mistype page before you let a subtype description decide.
The evidence
What the research does — and doesn’t — establish
Honest answer: the subtype system is a teaching model, not a measured fact. It is worth knowing exactly how much weight it can bear.
Research evidence: the strongest review of the field (Hook et al. 2021) found mixed reliability and validity for the core nine types and noted that factor analyses “typically found fewer than nine factors.” If the nine base types are not cleanly established, the 27 subtypes — a finer cut on top — have even less empirical support; they have been formally studied far less than the types themselves. Some instruments report a subtype (the iEQ9 and WEPSS among them), but none has published a validation of subtype accuracy a skeptic could check.
Our interpretation: use the instincts the way you’d use a good metaphor — to notice something true about yourself you hadn’t named, not as a verdict. A “that’s so me” jolt from a subtype description is real and useful, and it is not evidence the label is correct. We keep the instincts in the reflection lane on purpose.
Getting started
How to find your dominant instinct — and how we handle it
The quickest read is to notice where your attention goes when nothing is demanding it. Do you drift to the state of your home, your body, your reserves (self-preservation)? To the group, your standing, who’s in and who’s out (social)? To the one person in the room you most want to reach (one-to-one)? The instinct you’d most hate to lose is usually your lead.
The instinct you’d most hate to lose is usually your lead.
The Crossing’s methodology: our test scores your core type — the motivation underneath — not your instinctual variant, because the instrument doesn’t measure the instincts and we won’t report a number we haven’t earned. Your report includes a short instincts section that teaches the three drives and invites you to place yourself, clearly labeled as self-reflection rather than a scored result. That’s the honest version of subtypes: real enough to be worth a page, unproven enough to keep out of the scoring. See how we draw that line on our science page, then take The Crossing to find the type your instinct is riding on.
Frequently asked questions
- What are the three instincts in the Enneagram?
- Self-preservation (safety, comfort, resources, routine), social (belonging, group, status, contribution), and sexual or one-to-one (intensity, chemistry, focused bonds). Everyone runs all three; traditionally one leads, one supports, and one is neglected.
- What is a countertype?
- The one subtype in each type that looks least like the type — its dominant instinct pushes against the type's usual style. The self-preservation Four, for example, is more stoic and self-reliant than the expressive Four most people picture.
- Does The Crossing tell me my instinctual variant?
- No. The Crossing scores your core type, not your subtype — our instrument does not measure the instincts. Your report includes a self-locate section for the three instincts, clearly labeled as reflection to place yourself in, not a scored result.
- Are instinctual subtypes scientifically proven?
- No. The 27-subtype system is a rich teaching model, but its empirical support is thin — even the core nine types don't cleanly recover in factor analyses (Hook et al. 2021), and subtype validity is studied far less. Treat it as a lens, not a measured fact.
- What's the difference between a wing and a subtype?
- Your wing is one of the two types next to yours on the circle, flavoring your core type. Your instinctual variant is a survival drive layered over any type. They answer different questions — which neighbor leans in, versus which instinct leads.
