Astrology and Horoscopes Astrology is the study of how the planets and stars affect human affairs. A horoscope consists of a geocentric map of the solar system at a given moment in time based on a person’s date, time, and place of birth.

Astrology and Horoscopes The calculations involved in constructing a horoscope are based on geocentric models of the solar system (i.e., earth is at the center). The interpretation of horoscopes is based on manuscripts and texts passed down across generations. Many of these are authored by respected astrologers. Many of the modern horoscopes that we are familiar with are highly simplified versions based on a person’s zodiac sign (e.g., Aquarius, Leo, Capricorn).

How do these methods fare? How do astrological methods compare with those discussed in this course? What would it take to establish the validity of an astrological theory? Are these methods (or the evidence derived from them) part of what is advertised?

Testing Astrology What would it take to test astrological principles? –different astrologers should make similar predictions –the person types based on the Zodiac should be accurate (Aries: high extraversion; Gemini: high extraversion, high agreeableness; Pisces: high openness) –horoscope should be correct
