The validity of astrological predictions on marriage and divorce: a longitudinal analysis of Swedish register data

This paper examines astrology, a concept that is considered unscientific by broad segments of the population in the western world. Despite this, astrology remains for some an important source for advice regarding choices in a range of different matters, including career and relationships. The continuing popularity of astrology may at least partly be linked to an insufficient body of empirical research that has been able to test hypotheses formulated by astrological theory, both due to a lack of data beyond very small study populations as well as astrological predictions frequently being vague and thereby difficult to test. This article examines how differences in astrological favorability influence partner choice in marriage as well as the divorce risk among married couples using longitudinal individual-level data from Sweden over the period 1968-2001. The results fail to provide any consistent evidence to support the notion that astrologically more compatible couples are either overrepresented among observed marital unions or associated with a lower risk of divorce.
