A Guided First Route

Start Here

One path through the system, from names to structure.

TetraTypes has become a reference library. This page gives you a first route through it: what to read first, what to leave until later, and how the pieces fit together.

The Short Version

Begin With People, Then Add Structure

Socionics can become abstract very quickly. The easiest entry point is usually not the theory in full detail, but the sixteen types as recognisable patterns of attention, strength, need, and relation.

Start with the type pages. Then return to Model A to understand why the type descriptions have the shape they do. Once Model A is familiar, the Bridge and Model L pages make more sense: they add resolution rather than replacing the classical frame.

The Explorer is best treated as a companion. Use it when you want to see the structure moving, compare types, or test how the elements rearrange across the system.

Video Guides

On The Channel

The channel is growing into a set of visual guides for the site. The introduction, two Model A deep dives, and the main Model L technical sequence are now available, with conceptual foundations and intertype material developing alongside them.

Guide One

Introduction To TetraTypes

A first visual route into the project: what TetraTypes is, how the site is arranged, and why the fourfold structure matters.

Now live Watch the introduction

Guide Two

Model A: The Seven Aspect Dichotomies

A 37-minute deep explanation of the seven aspect dichotomies: how the information elements are split, derived, and made intelligible.

Guide Four

Model L: 16 Monadic Elements

A visual introduction to the Model L sub-variant split: how eight classical elements become sixteen monadic elements.

Guide Five

Model L: Central, Radial, And The Four Capacities

A deeper Model L explanation of central and radial structure, the four capacities, and how the positions organise the sixteen monadic elements.

Model A AnchorCapacity expands Strong / Weak and the classical position regions into A, B, C, and D.

Guide Six

Model L: The Four Vergences

A further Model L guide focused on the four vergences and how they help organise the higher-resolution structure of the system.

Model A AnchorVergence expands Mental / Vital into four modes of directness, appearance, persistence, and tacitness.

Guide Seven

Model L: The Four Currents

A Model L guide to the Four Currents: Primary, Complementary, Supplementary, and Ancillary.

Model A AnchorCurrent expands Valued / Unvalued into four kinds of functional flow and alignment.

Guide Eight

Model L: The Four Perspectives

A Model L guide to the Four Perspectives: Necessitating, Accepting, Producing, and Supplying.

Model A AnchorEnsemble expands Accepting / Producing, while its group label Accepting remains one specific radial term.

Guide Nine

Model L: The Four Arrays

An orientation to Array as a function's assessment style and decision-making approach, connecting expressive emphasis with selective approach.

Model A AnchorArray expands Inert / Contact into four assessment styles and decision-making approaches.

Guide Ten

Model L: The Four Interests

A revised Model L guide to Interest, correcting Bold/Discreet and Pertinent/Incidental and their Reinin correspondences.

Model A AnchorInterest separates Bold / Discreet from Pertinent / Incidental, corresponding to Intensive / Extensive and Constructive / Corrective.

Guide Eleven

Model L: The Four Occupations

A Model L guide to Purview and the Occupation groups: Engrossing, Peripheral, Collateral, and Attendant.

Model A AnchorOccupation expands Evaluatory / Situational into four ways a position becomes an ongoing field of activity.

Guide Twelve

Model L: The Tetrachotomies

A dense synthesis video showing how the Reinin dichotomies, Model A function dichotomies, and Model L tetrachotomies fit together.

Model A AnchorModel L expands the seven Model A function dichotomies into seven four-part fields: Capacity, Vergence, Current, Perspective, Array, Interest, and Purview.

Model L: Conceptual Foundations

A shorter sequence focused on the conceptual shift beneath Model L: not another catalogue of positions, but a way of reading functions as coordinates in a generated field.

Foundation One

Model L: From Position to Coordinate

This opening short frames the deeper shift: Model L does not merely double Model A from eight functions to sixteen. It changes the reading from stack position to generated coordinate.

Recommended Route

Read These In Order

This sequence is meant for a first visit. It avoids the deepest reference material until the basic map is already in place.

1

The Cast

The Sixteen Type Pages

Meet the sixteen types first. Read a few profiles, notice which descriptions feel vivid, and do not worry yet about memorising the whole system.

Open the type pages
2

The Frame

Model A Foundations

Model A explains the eight elements, the eight functions, the four blocks, and why each type has a distinct arrangement of strengths and needs.

Read Model A
3

The Pattern

Type Dichotomies And Small Groups

Once the types are familiar, the dichotomies and small groups explain how the sixteen divide into recurring structural families.

Read the type dichotomies
4

The Resolution

The Bridge Into Model L

The Bridge shows why Model L was introduced: each classical element can be resolved into more specific sub-variants without discarding Model A.

Cross the Bridge
7

The Dynamics

Relations And The Explorer

Finish by looking at intertype relations and the Explorer. This is where the model becomes social: not just what a type is, but how types meet.

Three Ways To Use The Site

Light Read

I Want The Big Picture

Read this page, the type index, and one or two type pages. That gives you the human shape before the technical structure.

Reference Read

I Want The Mechanics

Use the Model A reference pages after the main Model A page: dichotomies, dimensions, and mechanics each handle a different layer.

Comparative Read

I Want To Compare Types

Use the Explorer alongside the type pages. Switch between types, watch the element positions change, and then return to the written profiles.

After The First Route

Where To Go Next

If you want more theory, read the Model A reference pages in this order: information dichotomies, dimensions and presence, then mechanics. If you want more human texture, stay with the type pages and intertype relations. If you want to test a typing, keep the page open but let the person in front of you remain the evidence.
