Can Your Chart Predict Who You Are?

An independent study testing whether the birth chart predicts your personality, your values, and how you see the world, the claims astrology makes about character, put to a real test.

Your traits are measured with the Big Five, the model academic psychology actually uses. Your chart is read blind, then checked against your answers, a few of which are sensitive, and entirely optional.

Methodology

Three related questions, evaluated separately, because a method can succeed at one and fail at another.

01

The Traits

Do the elements and planets predict your personality? Astrology has always claimed to, here it's measured against the Big Five, via a standard ten-item inventory, and scored.

Read from the chart
  • Element balance, fire, earth, air, water
  • Modality, cardinal, fixed, mutable
  • Sun, Moon & Ascendant
  • Overall planetary emphasis
02

The Outlook

Beyond traits, your core values, your optimism, your appetite for risk, and, if you choose to share them, how you see the world.

What we ask
  • Your core values (top three)
  • Optimism, risk & tempo
  • Political & spiritual leaning, optional, anonymous
03

The Real Chart

Does your true birth chart do better than plausible incorrect ones? This isolates whether the correct data adds anything beyond common patterns.

The comparisons
  • Your real chart
  • Matched sham charts, scored by the same rules
  • A base-rate baseline, a non-astrological control

The Findings

This study publishes in three phases, each one a deeper look as the data grows: a first read of the signal at 400 charts, a stronger pass with tighter estimates at 2,500, and the complete analysis at 5,000.

Phase 1Now filling

Preliminary

A first look at the data once 400 charts are in. Early signal, wide error bars, published openly.

Phase 2Now filling

Expanded

The analysis rerun at 2,500 charts. Tighter estimates, subgroup checks, and a look at what held up from Phase 1.

Phase 3Now filling

Full

The complete analysis at 5,000 charts. The final word on what this study found, hits and misses alike.

Status: the first milestone is still filling. Preliminary findings will be published right here the moment Phase 1 completes, every participant gets word when they land, and the analysis then rolls forward through the expanded and full phases as more charts arrive.

How It Stays Honest

A real test. Mainstream research has mostly found astrology and personality unrelated, so this study can genuinely fail. If the chart predicts nothing here, that's a finding, and it gets published.

Standard instruments. Personality is measured with the Big Five, so the results are comparable to published psychology, not a bespoke quiz.

Sensitive answers are optional. Political and spiritual questions are yours to skip; anything shared is kept anonymous, used only in aggregate, and never sold.
