A Human Design profile is two numbers from 1 to 6: the line of the personality Sun and the line of the design Sun. That gives twelve combinations, and almost everywhere they are presented as equals. They are not. We computed 12,000 bodygraphs over a uniform sample of births between 1940 and 2015, and the distribution turned out sharply uneven.
How common each profile is
- 6/2: 14.92%
- 2/4: 14.68%
- 4/6: 14.51%
- 3/5: 14.35%
- 5/1: 14.16%
- 1/3: 14.09%
- 3/6: 2.40%
- 4/1: 2.33%
- 2/5: 2.33%
- 6/3: 2.28%
- 5/2: 2.03%
- 1/4: 1.91%
The first six profiles together account for 86.7% of people, the last six for 13.3%. The most common occurs seven times more often than the rarest. If you have met someone with a 1/4 or 5/2, that really is unusual.
Why it comes out this way
The reason is purely geometric, and you can check it on paper. The design Sun always sits exactly 88° of solar arc before the personality Sun. One gate occupies 5.625° of the zodiac and one line 0.9375°. Divide: 88 divided by 0.9375 gives 93.87 lines.
Subtracting 93.87 lines is the same as adding 2.13 lines, since a gate holds six lines and 96 minus 93.87 leaves 2.13. Lines are discrete, so the design line almost always lands two positions further along than the personality line, and only when the Sun sits in the last 13% of a line does it shift by three.
That gives a prediction: 86.67% of charts should show a two-line shift and 13.33% a three-line shift. Our calculation returned 86.71% and 13.28%. The gap is under half a tenth of a percentage point.
So the six common profiles are exactly those where the second digit is two higher than the first, wrapping past six: 1/3, 2/4, 3/5, 4/6, 5/1, 6/2. The rare six are the three-line shift: 1/4, 2/5, 3/6, 4/1, 5/2, 6/3.
Three geometries
Profiles are also grouped by the geometry of the life path. In our sample it came out like this.
- Right Angle (1/3, 1/4, 2/4, 2/5, 3/5, 3/6, 4/6): 64.3%
- Left Angle (5/1, 5/2, 6/2, 6/3): 33.4%
- Juxtaposition (4/1): 2.3%
Right Angle is the personal path, where the main lessons are worked through alone. Left Angle is the transpersonal one, where the decisive turns arrive through other people. Juxtaposition is a single profile, 4/1, and it shows up in two people out of a hundred.
What the six lines mean
1 (Investigator) needs a foundation. Will not move until things are understood, and that is a working method rather than a lack of confidence.
2 (Hermit) carries a natural talent that switches itself on, and needs time alone. The call usually comes from outside rather than from self-promotion.
3 (Martyr) learns by trial and error. A mistake here is not a malfunction but the method: it is how what does not work gets filtered out.
4 (Opportunist) lives through a network. Work, housing and relationships arrive through people already known.
5 (Heretic) attracts projection: even strangers expect a solution from them. Works well wherever there is something to fix.
6 (Role Model) lives in three stages: trial until thirty, observation from thirty to fifty, stepping into the role of example after that.
In short
There are twelve profiles, but six of them cover 86.7% of people and the remaining six 13.3%. This is not a statistic about character but a consequence of the design Sun sitting 88° before the personality Sun: the line shift is almost always two.
Your own profile is visible in a bodygraph built on an exact birth time. A quarter of an hour can change the line, so the time matters.
