Tritype

One type from each center

Tritype is the idea that a person draws on one type from each of the three centers. The core type sits in one center. The other two centers each contribute the type whose strategy that person uses most readily when the concerns of that center come up.

Katherine Chernick Fauvre developed the model in the 1990s through research on how people of the same core type differed. She proposed that the three types, called fixes, work together as a set. The core leads, and the other two act as the preferred ways of handling identity, uncertainty, or autonomy when those issues come up.

A tritype always contains one Body type (8, 9, or 1), one Heart type (2, 3, or 4), and one Head type (5, 6, or 7). That rule produces 27 possible combinations.

How tritype differs from wings and instincts

A wing is a neighboring point on the circle, so it describes a shade of the core type. A tritype fix comes from a different center and describes a separate strategy the person brings in for a different kind of problem. Nine's wings are 8 and 1, both Body types, so neither can appear as a fix in a tritype led by Nine. The same holds for Three, whose wings sit in the Heart center, and Six, whose wings sit in the Head center.

For the other six types, a wing and a fix can share a number. A One with a Two wing may also carry 2 as the Heart fix. The labels then make two separate claims: the wing describes the color of the One pattern, and the fix describes what that person does when worth or connection is at stake.

Instincts describe where attention and energy go in daily life: self-preservation, social belonging, or one-to-one intensity. Tritype describes which type strategies a person combines. The two can be read together. A 6-9-3 with a self-preservation stacking and a 6-9-3 with a social stacking share the same three fixes and organize their priorities differently.

Reading the order

The first number is the core type. The second is the fix used most after the core, and the third is the one used least. The written order shows strength, which is why 4-5-1 and 1-4-5 describe different people even though they use the same three types.

Each set of three numbers can be written in six orders, giving 162 possible tritypes. The 27 combinations below describe the shared theme of each set. The order then tells you which part of that theme leads.

Some teachers add a wing to each fix, writing something like 4w5-1w9-5w4. This adds detail, and it also multiplies the claims that need to be checked against real behavior. Start with the three numbers before adding anything else.

• 4-5-1: identity leads, with analysis close behind and correction kept in the background.
• 1-4-5: correction leads, with a strong pull toward personal meaning and a smaller role for detached analysis.
• 5-1-4: analysis leads, with high standards second and emotional depth third.

Finding your tritype

Begin with the core type. Tritype adds to a core type; it does not replace one. Then look at each of the other two centers on its own and ask which response you reach for when that center's concern is active.

Use concrete situations. Recall a time when your worth felt questioned, a time when you felt unsure what would happen next, and a time when someone pushed against your autonomy. Notice what you actually did, which can differ from what you admire or wish you had done.

Working on tritype sometimes turns up a mistyped core. A person may find that what they took to be a fix explains their recurring stakes better than the type they started with. Treat that as a reason to reread the type articles.

• Body: when your autonomy or boundaries are pressed, do you push back (8), go along to keep the peace (9), or set things right (1)?
• Heart: when your worth or image is at stake, do you move toward others with help (2), show what you can accomplish (3), or withdraw into your own depth and difference (4)?
• Head: when the next step is uncertain, do you gather knowledge in private (5), check for support and prepare for problems (6), or open up new options (7)?

Limits and debates

Tritype came later than the foundations of the modern Enneagram. Claudio Naranjo's psychological descriptions, which shaped most current type portraits, center on a single type with its subtypes. Oscar Ichazo's Arica teaching describes a related idea it calls the trifix, within its own framework and terminology. Fauvre's tritype is a separate model with its own method and descriptions.

Many teachers leave tritype out. One argument is that the core type already involves all three centers through its wings and connected points, so a second and third type add labels without adding much explanation. Another is that the model has little independent research behind it, and that self-reports of three fixes are harder to check than a single core type.

Used carefully, tritype can still be a helpful lens. It gives a vocabulary for differences between people of the same type and a reminder that everyone has habits in all three centers. Its value depends on whether it explains real patterns in your life better than the core type alone.
