Summary
Pre-registered double-blind test in which professional astrologers, working with full natal charts, performed at chance when matching charts to subjects' California Psychological Inventory profiles.
Why it matters here
The most-cited rigorous test of literal-prediction astrology; the result is null and has not been overturned by subsequent replications.
