Human Design: type, authority, and the nine centers
Human Design lays two sets of activations onto a fixed 64-gate wheel. A channel exists only when both gates are on. Centers, type, and authority follow from those channels. There is no score.

Chart system
Personality uses the birth instant. Design uses the earlier instant when the Sun’s longitude was exactly 88° behind. Birth time to the minute is enough; coordinates are not a separate palace system.

Overview
An overview of Human Design
Human Design lays two sets of activations on 64 gates. A channel exists only when both ends are present. Type, authority, and profile all come from gates that are already on. The chart has no score.

Type and authority
Type and authority
Type looks at whether the Sacral is defined and whether a motor reaches the Throat. Authority takes the first item that holds, in a fixed order. Neither is a grade on a personality test.

Centers and channels
The nine centers and the channels
A center is defined only when a complete channel reaches it. A single gate can hang inside a center and still leave it undefined.

Profile
Profile
Profile is the line of the personality Sun and the line of the design Sun, for example 3/5. It is two line numbers. It is not a personality score and not another name for type.

Human Design connection
Human Design connection: composite, electromagnetic, companionship
A connection chart is three set operations on two graphs. The union is the composite. The intersection is companionship. A channel that one person holds completely, while the other holds only one gate, is a one-sided fit. Nothing is weighted.

What questions this chart can hold
Human Design fits structural questions: which centers a channel defines, and where type and authority therefore land. It does not score anyone, and it does not replace a medical or employment decision.

What Human Design calculates
The raw material is two moments and thirteen positions in each. Personality takes the birth instant. Design takes the earlier instant at which the Sun’s ecliptic longitude was exactly 88° less. That offset is a numeric solve, not a hidden school setting.
Activated gates are a set. A channel lights only when both ends are in the set. Defined centers are the ones a channel connects. Type and inner authority are read from that definition, not from a personality paragraph.
What fateshow prints
Type is one of Manifestor, Generator, Manifesting Generator, Projector, or Reflector, decided by whether the Sacral is defined and whether a motor reaches the Throat. Authority follows a fixed priority: emotional, sacral, splenic, ego, self-projected, mental, with the lunar cycle for Reflectors.
Profile is the two line numbers of the personality Sun and the design Sun, such as 3/5. The chart does not assign weights or a total score. An open center is an opening in the graph, not a defect the engine has measured.
What it is not
It is not a natal-aspect reading, and type is not a rank of ability. Strategy says how a type starts something. It does not say what someone is allowed to do.
A vague birth hour is not enough. The design instant is solved from solar longitude, so a wrong minute can move gates. Do not round an unknown time into a type.
Safety boundary
Type and authority are a decision metaphor built from gate sets. They are not medical, legal, or financial advice, and an undefined center is not a diagnosis.
Common mistakes
- Treating type as a talent score.
- Reading an open center as something broken.
- Casting a chart from a guessed birth minute.

Frequently asked questions
What does type actually decide?
How the chart is defined around the Sacral and the motors to the Throat. That is a start-up pattern, not a measure of skill.
Why is the design date before birth?
It is the earlier moment when the Sun was 88° of longitude behind the birth Sun. The date is solved; it is not chosen from a table of ages.
Does the chart produce a compatibility percentage?
No. A single chart has no score. Relationship overlays live on the Human Design connection page, and those overlays are sets, not points.
