Different interpretive systems The studio calculates numerology values from dates and names. It does not calculate natal charts, planetary positions, houses, or transits. Birth time and location are optional context for a future human consultation.
Evidence boundary A controlled study of a specific natal-astrology matching task was published by Shawn Carlson in Nature in 1985. A test of one task is not a complete history of astrology, and it does not establish the validity of numerology.
Ask clearly Before a consultation, ask which system will be used, how the interpretation is formed, and what its limits are.
