The Differentiation Study — The Mirror Test
This one is the control that makes the others meaningful. Read the short "reading" below as if it were your own Human Design result, and rate how accurately it describes you. Then you'll be told what it really was. If a single generic paragraph scores high with everyone, that number is the baseline every real result has to beat. (Companion to the Type, Profile, and Authority tests; method and pre-registration on the validation record.)
Method & pre-registration
Hypothesis (pre-registered): participants will rate a single, deliberately generic statement — identical for everyone — as accurately describing them, at a mean well above the scale's midpoint. This is the classic Barnum / Forer effect. Its purpose is to establish the baseline "accuracy" that any personalized reading must exceed to show real signal.
Design: every participant sees the same paragraph, presented as their Human Design reading, and rates it 1 (not at all) to 5 (very accurately). The paragraph is a Forer-style statement of universally applicable claims.
Data & privacy: only the 1–5 rating is stored — no names, no birth data, no accounts. Aggregate only, live, below. The archive reports the number and draws no verdict.
Your reading
Your Human Design suggests you have a good deal of unused capacity you have not yet turned to your advantage. While you have some personality weaknesses, you are generally able to compensate for them. At times you are outgoing and sociable; at other times you are reserved and reflective. You have a strong need for other people to like and respect you, and can be critical of yourself. You prefer a certain amount of variety and change, and feel dissatisfied when hemmed in by restrictions. You pride yourself on being an independent thinker and do not accept others' opinions without satisfactory proof. You have found it unwise to be too candid in revealing yourself to others.
How accurately does this describe you?
The reveal
That paragraph was not a Human Design reading at all. It is a version of the classic Forer statement — a set of vague, flattering claims that fit almost anyone. Nearly everyone rates it as an accurate description of themselves. That is the Barnum effect, and it is why "it resonated with me" cannot, on its own, tell you whether a system is measuring anything real. Here is how everyone has rated it so far:
