The Accuracy Experiment

Can 22 personality questions predict your Sun, Moon, and Rising before you tell us anything about your birth? We measure it, in public. These numbers update as people reveal their real charts — and they stay up whether they flatter us or not.

Exact matches, by placement

The dashed line is chance: guessing a sign at random is right 8.3% of the time.

Honest caveat: 6 reveals is a small sample, and small samples swing both ways. The bars will steady as the count grows — that's part of what this page is for.

How the experiment works

1. You answer 22 questions about how you operate — no birth details, no leading hints. The quiz maps your answers to probabilities across all twelve signs for each placement.
2. You reveal: enter your birth date (and time and place, if you know them), and we compute your actual chart from JPL ephemeris data.
3. Each prediction is scored exact, close (same element), or a miss — and joins the totals above, anonymously.
4. If a placement can't be pinned down from the birth details given, it isn't scored at all. No birth time on a day the Moon changed signs, or on a Sun-sign cusp day, means that placement is genuinely ambiguous — we show the possible range instead of picking a winner, and it never enters the totals. Rising always needs an exact time and place.

Why publish it? Because every astrology app asks for your trust, and we'd rather earn it with a number you can check than a testimonial you can't. If the quiz beats chance, that's interesting. If it doesn't, you'll see that here too — and every reveal makes the next version of the quiz better, because the scoring weights are tuned against real outcomes.
