What is Humun Design?

Howdy folks. Humun Design is a modern mythology: a persunality map that one man set down in 1987 after an eight-day mystical experience, built on the I Ching, astrology and a few older systems. No standard laboratory has tested it, that we know of, and most of what it claims sits outside what a laboratory is built to measure. You don’t have to believe any of it. What it offers is a vocabulary, and some things to try. Think of it as a life hack with one catch: it only works as far as you use it to look at yourself. This page says why it matters, what it is, where it came from, what it claims, what its critics say, and how we use it without pretending it is something it isn’t.

About the spelling: we write it with two u’s, and we write persun and persunal the same way, because the ordinary words carry “man” and “son” inside them. A map of what a persun is shouldn’t have a gender built into its name; nobody is the default, and the word should belong to everyone. The system’s own books spell it the usual way.

Why any of this matters

“Finally meet yourself, and fall in love with what you find.”

Rebecca Jolli

Most of us were taught, early and thoroughly, that what we are naturally is not good enough. The lesson arrives in layers: you’re fine, and you also need to sit still, to read before you’re ready, to compete, to want what everyone else wants. Each layer lands on top of a quiet “no” that a two-year-old can feel and a twenty-eight-year-old has long since forgotten. Somewhere in there a small persun gives up a part of themselves, notices, and knows there will be a price.

The price gets paid for decades. It shows up as a life that doesn’t quite fit, work that runs on willpower, a body that keeps saying no in ways that get louder. Some people come through the conditioning and find a way to thrive. Many keep hitting the same wall until the body says “change or die”, and some carry it to the grave. The difference is whether a persun ever got to see a spread of possibilities and feel which one was theirs. That is what a chart is for. It is the seed packet you arrived with: the variety, the light it leans toward, the water it wants. With it in hand, the seed itself and the trellis somebody else built around it can finally be told apart.

None of that is a grudge against the people who did the conditioning. They were working under the same false premises and the same incomplete knowledge, and so were we. Now we know a little more, and that is the whole of the forgiveness required.

Passengers

The deeper claim, and the one Ra returns to over and over, is that we are here as passengers. The body has a life of its own: a natural spirit, as in any animal, that already knows where it belongs and when. Consciousness gets to ride along and watch. Taken seriously, that makes a life something closer to a film you are in the audience for, all the input arriving click by click, the dropped ball bouncing exactly where it needed to land. Rebecca’s shorthand for the practice is the trick of being in the right place at the right time. For a Coordinator or an Observer especially, that is the job, and the chart is one way of getting sensitive enough to find it.

Living that way changes what growth feels like. A realization arrives as “what a cool idea, and what does it imply”, and life rearranges around it. The other version is the one most of us know well: crash to crash, with a life as a series of headaches, each wall recognized only after it has been hit.

Weather and climate

The chart also helps tell the weather from the climate. Some patterns run for years, long enough to feel like a new self. A persun builds a business inside one transit, then the planet behind it moves on, the energy goes with it, and they are left asking why they can’t do the thing they thought was them. The chart draws the line between what is yours for life and what is passing through, what Ra called the neutrino weather.

A different kind of science

Ra called the system the science of differentiation, and the word is worth a note. This is a collective, experiential science, and it runs on the other side of the brain from the logical kind. A persun submits to an experience, a crisis, a mistake, an afternoon in a canoe, and afterward has something to reflect on. Once learned, the lesson doesn’t need repeating. A body of knowledge built that way is every bit as real to the persun who built it, and it carries a smaller kind of truth: true for them, at that time. Our culture places little value on that knowledge. This page is partly an argument that it should.

Most of the work is looking backward. Decisions made at five, while coping, became assumptions, and the assumptions led somewhere nobody chose. The root belief is usually far back, at the cusp where a whole path began, and getting there means retracing some of that path. That’s hard, and the sunk cost is real: eight years building a boat is a lot to set down before its first sail. The way back is shorter than the way out, because the path is known.

“Learn who you are, so you can love that. Meet yourself, and love what you see. Fall in love with what you find.”

Rebecca Jolli

Where it comes from

Here is the origin story as the system’s own keepers tell it. In January 1987, on the island of Ibiza, a Canadian named Alan Robert Krakower had an eight-day mystical experience: an encounter with what he called “a Voice”, which he said gave him the whole system. He took the name Ra Uru Hu, wrote down what he had received, published The Human Design System in 1992, and taught it until he died in 2011. (Jovian Archive, IHDS, Wikipedia)

The story practitioners pass on, by word of mouth rather than in any document, adds that the information was available to anyone that week. He was the one able to receive it and carry it to the rest of the world, and at least one other person who received it was not able to bear it. Nothing written stands behind that part, so hold it as lore.

The parts are older than 1987. The 64 numbers on a chart are the 64 hexagrams of the I Ching, a text people have been reading their lives into for roughly three thousand years. The planets come from Western astrology. The nine centers are loosely borrowed from the chakras, and the way the pieces connect borrows from the Kabbalah’s tree of life. The literature also adds a layer of physics. Its keepers say the Voice told Ra that neutrinos have mass and carry the imprint, the neutrino stream, as practitioners call it, at a time when physics treated them as massless. Evidence that neutrinos have mass arrived in 1998 and won the 2015 Nobel Prize. Whether that is the physics catching up, or a lucky line in a story nobody can check, or a bit of both, which is where most of us land on most days, depends on how you hold the story, and we come to that next. No physicist has found a way to test the imprint part yet. (Wikipedia; Jovian Archive on the neutrino claim; Nobel Prize, 2015)

We put the story first because it matters. There is no laboratory behind this in the usual sense: no controlled study, no peer review. There is a story, a set of rules, and nearly thirty-five years of people testing it in the one laboratory each of us has, our own life. You can hold the story however you like. Between the two of us, we hold it differently. One of us holds it as a myth in the old sense of the word: a story people use to understand themselves. The other holds it as a claim about how the universe is built, one the sciences haven’t caught up with yet. Neither of us knows for sure, and both of us feel strongly, which is how most things go around here. We agree on what we won’t do with it, and that is what most of this page is about.

What a chart is

The chart is the seed packet: the variety, the light it leans toward, the water it wants, the season it wakes up in. The rest of this section is how the packet gets printed. A chart starts with two moments: the minute you were born, and a moment about three months earlier, when the Sun was 88 degrees back along its yearly path. Why that moment? In the system’s account, that is when consciousness is downloaded into the fetus, and the fetus becomes a separate conscious entity from its mother. The body’s unconscious “design” is imprinted then, and the conscious “persunality” is imprinted at birth. That is the system’s answer, and we pass it on as the system’s answer. For each moment, the positions of the Sun, Moon, lunar nodes and planets are sorted into 64 slices of the sky, one per hexagram. Those slices are the numbers on the chart. The nine shapes are centers, the lines between them are channels, and a channel lit at both ends is called defined. Each of the 64 slices is itself cut six ways into lines, and each line six ways again into colors, then six tones, then five bases, so the imprint can be read at four finer levels under the number you see on the chart. From that pattern the system assigns a type, a strategy, an authority (its word for how you make decisions), a profile, and a great deal more. (Jovian Archive, “Personality vs. Design”; Jovian Archive, on the 88 degrees)

Inner and outer authority

Authority comes in two kinds. Inner authority is what you can trust to make good decisions as the unique individual you are; the chart names where in the body it lives for you, and for nobody is it the mind. Outer authority is the mind’s proper job: once it is relieved of decision duty, what it knows becomes something to offer other people.

The astronomy is real and reproducible: anyone with the same birth data gets the same chart, to the second. Keep that fact in its place. An exact calculation doesn’t make the meanings true; the meanings are a separate question, and they are the whole point. We won’t use the precision as if it were proof, and you shouldn’t let anyone else either.

On this site we use the type names from 64keys, a software company started by two of Ra’s direct students, who were behind the camera for the filmed account of his story and have carried the system forward through decades of their own practice. They found the traditional labels “insufficiently meaningful” once their charts were being used at work. Both names appear on their charts, and here: Initiator (Manifestor), Builder (Generator), Specialist (Manifesting Generator), Coordinator (Projector) and Observer (Reflector). When Ra’s wording and the 64keys gloss differ, we read them side by side rather than pick one. They are two attempts at explaining the same information, and Ra had a big job that he did not finish, so in places the later refinement is simply further along. (64keys FAQ)

The chart is where you start. The parts that light up are the seed, and everyone is also conditioned by the people around them, if nobody else then the parents or whoever did the caretaking. Set a caretaker’s chart beside yours and specific influences come into view: the kinds of information they gave you consistent access to, the trellis you grew along. All of that is read from information that is publicly available.

What it says about itself

We’d rather you hear its own claims than our summary of them. Here they are, the humble ones and the large ones side by side.

“Don’t believe me.”

Ra Uru Hu, as a student recalls him saying during a reading, before telling them to experiment and find out for themselves. Jovian Archive, “Don’t Believe Me”

“it’s not about believing; and it certainly isn’t about believing me.”

Ra Uru Hu. Jovian Archive, “Your Truth”

“Your mind is not for decision making.”

Ra Uru Hu, who presents it as something that had never been said before. Jovian Archive, “The Mind is Not for Decision Making”

Deconditioning: “the seven-year cellular process of transferring decision making from your mind to your Inner Authority by following the Strategy of your Type.”

Jovian Archive, Human Design Dictionary. Ra put a number on it so that nobody would mistake seeing their chart for living it. Deconditioning means doing your homework: sitting with each activation and watching yourself do the things the chart says you do, line upon line, for years. The seven is a marker for the long view, borrowed from the folk idea that the body renews itself every seven years, not a finish line: Ra is remembered saying he was still deconditioning in his third cycle. Plan on the rest of your life.

“You are unique. You have no choice. Love yourself.”

Ra Uru Hu’s own mantra, as he describes it in The Line Companion (Jovian Archive). See also Jovian Archive, “Love Yourself”.

“if you push, if you initiate like an energy being, bitterness arrives. It always does.”

On the Projector type (Coordinator, in the names we use). Jovian Archive, “What is a Projector in Human Design?”. This is the texture of the advice: specific and unhedged. No judgment in Humun Design, though: bitterness here is a signal, not a character flaw. It is the other end of the same spectrum as success.

“The Science of Differentiation.”

The subtitle of The Definitive Book of Human Design by Ra Uru Hu and Lynda Bunnell, which its publisher describes as “a concrete map to the nature of being”. The same tradition says Human Design “is not a belief system”. (IHDS; Jovian Archive, beginner’s guide)

Read those together and you can see the tension. The same tradition that says “don’t believe me” also calls itself a science and tells you that you have no choice. We don’t resolve that for you. We just want you to see it before you decide how to hold the rest.

What it doesn’t claim, and what we don’t

If a practitioner ever tells you that your chart requires you to do something, they have left the framework. Everything in it rests on your own authority. Take what’s useful and leave the rest, and that includes the authority to put the whole thing down.

What the critics say

Wikipedia opens its article by calling Human Design “a pseudoscientific theory and practice described as a holistic self-knowledge system”. (Wikipedia)

Brian Dunning’s Skeptoid podcast spent an episode on it and concluded that it “lacks any theoretical basis and any set of falsifiable predictions that can be tested”. He also generated a chart for a birth he made up and got a complete, confident description. A chart describes a birth moment, not a named person, and someone is born in almost every minute, so the chart he drew is probably somebody’s. His point stands in the form that matters: the system will describe any moment with the same confidence, and whether a reading fits the person in front of it is the only test there is. (Skeptoid #770)

The best-known study behind the “it fits anyone” objection is older than Human Design. In 1949 Bertram Forer gave 39 students what they believed were personal profiles. Everyone received the same text, assembled from an astrology book, and they rated its accuracy at 4.26 out of 5. The effect now carries his name. Does that settle it? No. It settles what kind of claim this is, and it is the reason the useful parts of a reading are the parts specific enough to be wrong. (Forer, 1949; Barnum effect)

We know of no peer-reviewed, controlled test of Humun Design. What exists is field use. 64keys says its software has been “tried and tested for many years by thousands of coaches, therapists and management consultants”, and practitioners have been running their own informal experiments since 1992. That is experience, which is worth something, and it is not a controlled study. We would rather call it what it is. (64keys)

The critics are right that the evidence, in the laboratory sense, isn’t there. We would rather say that here than have you discover it later and wonder what else we left out.

If you like Myers-Briggs

Plenty of people who wouldn’t touch astrology will happily tell you they’re an INFJ. It is worth knowing what the research says about the MBTI. In a 1993 review, David Pittenger reported that even with a five-week gap, “as many as 50 percent of the people will be classified into a different type” on retest. In 1989, McCrae and Costa found that the four MBTI scales measure aspects of four of the Big Five traits, which have the stronger research record. And Jung, whose ideas the MBTI adapts, cast horoscopes for difficult cases “to have a further point of view from an entirely different angle”. (Pittenger, 1993; McCrae & Costa, 1989; Jung, letter to B. V. Raman, 1947)

None of that is a dig. It is the honest reason to use any of these systems: not because they are proven, but because they give you words for things you half-knew. By that standard, Humun Design is in the same family as the MBTI. It is a vocabulary chosen for its usefulness, with a stranger origin story and a great deal more detail.

For skeptics

If you were trained in science, or you simply like evidence, you may be here because someone you care about got into this and you’re worried. That is a reasonable response. It is the one most people with that training have. One of us came up through physics and lately spent a weekend fielding exactly these questions from old friends, so this section is written with them in mind. It is for you, and it isn’t trying to win.

Start with what you’re right about. There is no evidence for Humun Design in the sense you mean: no controlled study, nothing peer-reviewed. Its origin story is a mystical experience, and its vocabulary comes from systems older than the scientific method. Set against that: the I Ching is three thousand years of people reading patterns in humun lives, and thirty-five years of charts landing for people is not nothing. You can weigh that as accumulated experience or as the pull of a good story; the cards below take both seriously. Either way, if someone presented it to you as a proven discovery about the universe, you would be right to walk away. We don’t present it that way.

Here are the concerns we hear most, in the words we hear them.

“It’s dangerous.”

What’s true in it

It can be. Self-knowledge systems hurt people in known ways. When they are sold as truth. When someone uses one instead of getting help they need. When a practitioner with influence over a vulnerable person starts giving instructions. When a reading becomes the reason to cut someone off or make a big decision. When it becomes a way to make money from people who are hurting.

What we do about it

We present it as a framework and say so on every page. We give no medical, legal or financial advice. We say plainly when a reading isn’t enough, and we point you toward someone who can help. We make no predictions. Every decision stays with you. And nothing is hidden: how the chart is built, where the meanings come from, and our own charts, if you ask.

“It’s vague enough to fit anyone.”

What’s true in it

Much of it is. Forer showed in 1949 that people will rate a generic sketch as highly accurate when they think it is about them, and a one-line typing (“you’re a Builder, so you have lots of energy”) is exactly that kind of sketch.

What we do about it

We spend our attention on the parts specific enough to be wrong. A reading that says only flattering things that would fit your neighbor is a bad reading, whatever system it came from. A fair test you can run yourself: read a reading written for someone else’s chart. If it fits you as well as your own, you have learned something true about readings, and we would want to know.

“It says you’re fixed at birth. Where’s the room to change?”

What’s true in it

The chart doesn’t change, and the system says so without softening it: “You have no choice.”

What it means

What is fixed is described as temperament, the hand you were dealt. Your life isn’t in the chart. The system’s own word for change is deconditioning: dropping the habits you picked up from other people that were never yours. That is the entire practice: going downstream instead of upstream, as we say around here, borrowing the phrase from Esther Hicks, working with the wiring you have instead of against it. The chart lays out traits, not a path. So is it fate? Not in the horoscope sense. Whether the rest is true of people is for you to judge.

“It borrows credibility from the planets and the math.”

What’s true in it

It does, constantly. The chart is built from real astronomy. The literature mentions neutrinos. Practitioners say “mechanics”. None of that connects the numbers to the meanings, and dressing a mythology in the language of physics borrows trust it hasn’t earned.

What we do about it

We won’t use the precision of the calculation as an argument for anything. If you catch us saying “the math is real” as if it settled something, call it.

“You could make one up from rocks, or the seasons, or tea leaves.”

What’s true in it

You could, and people have. Tarot, runes, the Enneagram, the Myers-Briggs, your grandmother’s sayings. Any set of symbols rich enough will prompt reflection.

Our answer

Then the test of a system isn’t its origin. It is its use. Does it give you words you didn’t have? Does it point your attention at something you can then check in your own life? This is the one we found useful. We won’t argue that it is special, and it isn’t the only one we use: around here it sits next to Chinese astrology and face reading as a quick-and-dirty cross-check, and in our experience they tend to tell the same story.

“Doesn’t it take away your agency?”

What’s true in it

Used badly, yes. Anything that tells you who you are can become an excuse. “I’m a Coordinator, so I don’t initiate” is a cage with a nice label on it. No judgment; everyone builds one at some point.

The direction we aim for

Internal out, not external in. The framework prompts you; you notice; you decide. If it ever starts deciding for you, you have stopped using it and started obeying it. We will say so if we see it happening.

“Why the moment of birth? Why 88 degrees? Why the planets?”

The honest answer

Nobody can show you why. Those are the rules of this particular game, as one man set them down in 1987. We don’t know the causal path and we won’t invent one. We use the system for its vocabulary, not its cosmology.

“Wouldn’t a therapist be better?”

The honest answer

Often, yes. A reading is not therapy, and we won’t pretend otherwise. Some people find a reading gives them language they then carry into therapy, and that is a good use of it. If you need help, get help. The chart will keep.

“Is it a cult?”

The honest answer

Humun Design isn’t an organization you join. It is a body of ideas with many teachers, some of whom disagree with each other. But any practice can go bad in the same ways: a teacher who can’t be questioned, secrecy about how things work, pressure to spend more, pressure to cut people off, people being told what to do. If you see those anywhere, here included, leave. Our rule for ourselves is that students should evaluate their teachers, and that goes for Ra Uru Hu too.

If someone you love is into it

You don’t need to decide whether Humun Design is true to tell whether it is doing someone good. Look at how they are using it.

Healthy signs

  • They call it a lens, a map, a game, a vocabulary.
  • They test it against their own life and drop what doesn’t fit.
  • They still make their own decisions, and own them.
  • They can laugh about it.
  • They will show you their chart and explain it without needing you to agree.

Worrying signs

  • Big decisions get attributed to the chart.
  • Money keeps going out.
  • New secrecy.
  • People get cut off because of a reading.
  • A practitioner is giving instructions.
  • “The chart says I can’t.”

If you are worried, ask questions rather than passing verdicts. “What has it given you?” opens more doors than “that’s not real”, and it gets you a truer answer. It is also what we would ask of you in return: judge it by its use, not its origin, and we will do the same.

How we hold it

Here is what we actually do with it, in three moves.

  1. Get the vocabulary. A reading gives you names for patterns you may already half-know. That is its first and largest gift.
  2. Pick one thing specific enough to be wrong. Not “I’m a Builder” but “when I say yes from my head instead of my gut, I resent it within a week.”
  3. Try it for a few weeks and keep what holds. When something doesn’t fit, you can shelve it, and that is fine. But in our experience the line that makes you say “that’s not me at all” is where the work starts, so sit with it a while before you shelve it. (The 5th gate story on the home page is the worked example.)

Our rules for ourselves

When we write about a chart, we try to describe only what we can see. In Heinlein’s Stranger in a Strange Land, a Fair Witness asked the colour of a house on a hill answers, “It’s white on this side.” That is the standard: this is what the chart says, this is what you told us, this is what we noticed. Never: this is who you are. (Wikiquote)

Still curious?

If you would like to see your own chart, ask. If not, no pressure, as always; pass on by if it’s not your thing. This page isn’t going anywhere. You can also make a free chart at 64keys.com and look around on your own first. The basics are free, and we would happily be made obsolete by them. A reading is for when you want a sherpa: someone who knows the mountain, for the part you can’t see from the bottom.

Ask about a reading

Take care of yourselves, folks. Ciao.
