What the bodygraph is actually showing you — Type, Strategy, Authority, Profile, and the 9 energy centers — and how to use it for the one thing it's really designed for: making better decisions.
Frequently asked questions
How is a Human Design chart calculated?
Your chart is calculated from your birth date, exact time, and location — the same inputs as a natal astrology chart. The system uses two snapshots of the planets: one at the moment of your birth (your conscious 'personality' calculation) and one about 88 days before your birth (your unconscious 'design' calculation). Those two snapshots are mapped onto a bodygraph with 9 energy centers and 64 gates, which then reveals your Type, Strategy, Authority, and Profile.
What are the 5 Human Design types?
Manifestor (about 9% of people) — initiators who are here to start things and inform others. Generator (about 35%) — life-force engines who thrive when they respond to what lights them up. Manifesting Generator (about 33%) — multi-passionate generators with a manifestor flavor; faster, less linear. Projector (about 20%) — guides who see others clearly and thrive on invitation and recognition. Reflector (about 1%) — mirrors of the community around them, with a 28-day decision cycle that matches the lunar month.
What is the difference between Human Design and astrology?
They share birth data and some symbols, but they ask different questions. Astrology describes your temperament, timing, and relational dynamics through the planets and houses. Human Design uses the same astronomy but layers in the I Ching, the chakra system, and the Kabbalistic Tree of Life to produce a practical strategy for decision-making and energy management. Many people use both together; they don't contradict each other.
What is my Authority in Human Design and why does it matter?
Your Authority is your inner decision-making mechanism — the part of you that knows yes or no before your mind starts arguing. The most common authorities are Emotional (wait through a wave of feeling before deciding), Sacral (immediate gut response, often a sound), and Splenic (a quiet, in-the-moment instinct). Following your Authority instead of your mind is the single most life-changing experiment Human Design offers.
Is Human Design scientific?
Human Design is not a scientific framework — it's a synthesized symbolic system created in 1987 by Ra Uru Hu. The astronomy underneath it is real, but the meanings layered onto it are interpretive. People use it because the experiment of living by your Strategy and Authority tends to produce noticeable shifts in energy and decision quality, not because it's been peer-reviewed. Treat it as a practice, not a science.
