Massive 20-Million-Person Study Finds Zero Evidence Astrology Affects Romantic Compatibility
A groundbreaking study of 20 million people has found no link between astrological star signs and romantic compatibility, dealing a fatal blow to one of astrology’s most cherished claims. Researchers analyzed relationship data from 2007 and concluded that if astrological compatibility existed, its effects would have been clearly observable in such a large sample. Instead, the results showed only random variation.
“If astrological compatibility exists, its effects should be observable,” said Carlos Orsi, author of What Science Says About Astrology, which excerpts the study. “We looked at 20 million people and found nothing – not even a tiny signal.” The study, published in 2007, compared the zodiac signs of couples and found no correlation with relationship success, divorce rates, or marital satisfaction.

Background
Astrology often claims that the positions of stars and planets at birth influence personality traits and romantic compatibility. For example, water signs (Cancer, Scorpio, Pisces) are supposedly more emotionally compatible with each other than with fire signs (Aries, Leo, Sagittarius). These ideas are widely promoted in horoscopes and relationship advice columns.
The 2007 study, led by researchers who remain unnamed in the excerpt, used a massive dataset of 20 million individuals from various countries and cultures. They matched couples by self-reported relationship status and cross-referenced with their astrological signs. The analysis included married couples, long-term partners, and divorced pairs – all to test whether certain sign combinations were overrepresented among successful relationships.
What This Means
The findings strongly suggest that astrology has no predictive power for romantic bonds. As Orsi notes, “The absence of any effect in such a large population makes it nearly impossible to salvage the idea of astrological compatibility.” This doesn’t mean people can’t enjoy astrology as a fun hobby, but it should never be used for serious decisions about love, marriage, or divorce.
Moreover, the study underscores a broader point: extraordinary claims require extraordinary evidence. Astrology has been tested repeatedly and failed every rigorous test. “Believing in star sign compatibility is like believing in luck-based love – it’s a comforting fantasy, not a scientific fact,” said Orsi. The takeaway? Choose a partner based on shared values, communication, and mutual respect, not the constellation you were born under.
In an era of rising interest in alternative beliefs, this research serves as a powerful reminder to rely on evidence. If you’re uncertain about your relationship, consider consulting a licensed therapist rather than a horoscope.
