This study takes a claim astrology makes constantly—this chart describes a person—and gives it a defined comparison. Participants complete a short personality inventory and answer questions about values, risk, optimism and decision-making.
Can a birth chart predict personality, values and the way someone meets the world?

Methodology
Personality, values and chart personalization are evaluated separately, because the chart may describe one more successfully than another.
01
The Traits
Which chart factors track personality: the elements, modalities or lights? Each is compared with the Big Five through a standard ten-item inventory.
Read from the chart
Element balance: fire, earth, air and water
Modality: cardinal, fixed and mutable
Sun, Moon and Ascendant
Overall planetary emphasis
02
The Outlook
Beyond broad traits, this part considers core values, optimism, appetite for risk and, when a participant chooses to share them, political and spiritual outlook.
What participants report
Three core values
Optimism, risk and tempo
Political and spiritual leaning, optional and anonymous
03
The Real Chart
Does the true birth chart perform better than plausible incorrect charts? This isolates whether correct birth data adds information beyond common patterns.
The comparisons
The participant’s real chart
Matched sham charts scored by the same rules
A base-rate baseline as a non-astrological control
Why this is measurable: Mainstream personality research has generally found astrology unrelated to measured traits. That makes a careful test more interesting, not less: the method has to outperform a clear null expectation.
The questionnaire
What You’ll Be Asked
Answer from your life as you remember it, not from what your chart or a previous reading says should be true.
01
Rate ten paired personality statements from strong disagreement to strong agreement.
02
Choose the values that matter most and place yourself on several outlook scales.
03
Optionally answer two sensitive questions that are analyzed only in aggregate.
The findings
Results in Three Phases
The analysis becomes more precise as the sample grows. Every phase keeps the misses.
Phase 1 Now filling
Preliminary
A first look at the signal once 400 charts are in. Early results, wide uncertainty, published openly.
Phase 2
Expanded
The analysis runs again at 2,500 charts, with tighter estimates and checks on what survived Phase 1.
Phase 3
Full
The complete analysis at 5,000 charts, including what worked, what failed and what remains uncertain.
How it stays honest
How We Keep It Honest
A real test. Mainstream research has generally found astrology and measured personality unrelated, so this study can genuinely fail. A null result is still a result and will be published.
Standard instruments. Personality is measured with the Big Five rather than a bespoke astrology quiz, allowing comparison with published psychology.
Sensitive answers are optional. Political and spiritual questions may be skipped. Any answers supplied are kept anonymous, analyzed only in aggregate and never sold.
