Determination in Human Design
Determination is the top left arrow of the Variable, set by the Color of the Design Sun and Earth, and it is the foundation of the Primary Health System (PHS). It isn't about what a person eats but how — the conditions and circumstances under which the body is designed to take in food. Because the brain depends on the quality of its nourishment, Determination shapes far more than digestion: it shapes how clearly the brain works and how a person takes in information.
There are six regimens, and each has a Left and a Right form, which makes twelve ways of digesting in all. A Left Determination is an Active brain — busy and stimulated, needing regular, generous fuel and taking in information directly, one thing at a time. A Right Determination is a Passive brain — relaxed and receptive, eating when hungry and absorbing information indirectly, often without noticing.
| Color | Regimen | Active (Left) | Passive (Right) | Group |
|---|---|---|---|---|
| 1 | Appetite | Consecutive | Alternating | Conditions, Rigid |
| 2 | Taste | Open | Closed | Conditions, Rigid |
| 3 | Thirst | Hot | Cold | Conditions, Energetic |
| 4 | Touch | Calm | Nervous | Circumstances, Energetic |
| 5 | Sound | High | Low | Circumstances, Sensitive |
| 6 | Light | Direct | Indirect | Circumstances, Sensitive |
The lower three Colors are Conditions: strict rules about the food itself — how many things at once, how much variety, what temperature. They are the older digestive systems, and Appetite, one thing at a time, is the oldest of all. The upper three are Circumstances: the food can be anything, but the setting must be right — calm or busy, loud or quiet, day or night. They are the more modern systems, and they often benefit from technology, from headphones to blackout curtains.
Eating against one's Determination is one of the deepest forms of conditioning, because food is shared, social, and tied to family and culture. That pull back into the way everyone else eats is what Determination transference describes. The way out is gradual: Strategy and Authority first, then an experiment with the regimen, noticing over weeks and months how the body and the mind respond. As with every Variable, an accurate birth time matters — the Color of the Design Sun can change within a few hours of birth time, and its direction within less than an hour.

Appetite in Human Design — Determination Color 1
Appetite is the first Determination, set by Color 1 of the Design Sun and Earth. It is the oldest digestive system, designed to take in one thing at a time, and its two forms are Consecutive and Alternating.

Taste in Human Design — Determination Color 2
Taste is the second Determination, set by Color 2 of the Design Sun and Earth. It is a highly selective digestive system that thrives on a set menu repeated day after day, changing only with the seasons. Its two forms are Open and Closed.

Thirst in Human Design — Determination Color 3
Thirst is the third Determination, set by Color 3 of the Design Sun and Earth. It is the regimen of temperature, where food must be warmer or cooler than the body to be digested well. Its two forms are Hot and Cold.

Touch in Human Design — Determination Color 4
Touch is the fourth Determination, set by Color 4 of the Design Sun and Earth. It is the first of the Circumstance regimens, where what matters is not the food but the setting it is eaten in. Its two forms are Calm and Nervous.

Sound in Human Design — Determination Color 5
Sound is the fifth Determination, set by Color 5 of the Design Sun and Earth. It is a Circumstance regimen in which the level of sound around a meal decides how well it is digested. Its two forms are High and Low.

Light in Human Design — Determination Color 6
Light is the sixth Determination, set by Color 6 of the Design Sun and Earth. It is the most sensitive regimen, in which the presence or absence of daylight decides when food is digested well. Its two forms are Direct and Indirect.
