But studies of sun sign pairings in such records have generally produced only negative results. For example Daneel , found no significant deviations from chance for and German divorces, Silverman found the same for American divorces and marriages, although a second sample of marriages found a small but significant surplus of sextiles and trines equivalent to an effect size of 0.
Summary of Taurus compatibility
Studies involving other planets and precise aspects have generally been just as negative, for example Shanks found nothing significant for marriages. Daneel R Ehescheidung und Geburtssternbild, Kosmobiologie November , Ehescheidung und Geburtsdatum, Zeitschrift fur Parapsychologie und Grenzgebiete der Psychologie 14, A recent Swiss study An apparent exception is a study of sun sign compatibility by Gunter Sachs The Astrology File , Orion who analysed birth data from the Swiss Federal Office of Statistics for couples who married or divorced between and It was the largest sample yet , married couples and , divorced couples.
Of the sign pairings, 25 were individually significant for marriage and 13 for divorce, so Sachs concluded that "star signs clearly are of particular importance when it comes to choosing a partner" page 70 although they "play a far less significant role in divorce than in marriage" page This conclusion was supported by a follow-up study in which each spouse was given a false birth date picked at random. The results were "statistically entirely unremarkable" page Furthermore, as noted by Suitbert Ertel in Sach's Astrology File on this website under Sun Signs, the sign preferences of husbands should tend to agree with the sign preferences of wives, but the mean rank correlation between preferences over the 66 unduplicated pairings AR-AR, AR-TA, Ertel's rankings used preferences based on Sach's published expectancies, which are rounded and occasionally lead to ties.
When Ertel's test is repeated with unrounded expectancies to avoid ties, the mean rank correlations are 0. The differences are small and do not affect the outcome.
Ertel concluded there was "no hint of the correspondences we would expect if Sach's results were genuinely due to astrology". More obviously, as shown in the figure below, the deviations from expectancy do not match the predictions of astrology. Sachs's sun sign results for marriage and divorce show little similarity with the previous figure.
Other than the apparent excess of conjunctions shown in red , which is probably due to recording bias see later , the ups and downs are all over the place. A more recent French study However, a more recent French study by Didier Castille Birth day effect on natality rhythms, Correlation From the Institut National de la Statistique et des Etudes Economiques National Institute for Statistics and Economic Studies he had obtained the dates of birth for all married couples to whom live children were born between and The result was a total of nearly 17 million couples.
Spouses born just a few days apart could of course have different sun signs whereas this approach gives them the same sun sign, so the conversion is far from exact. Nevertheless it should be good enough to pick up any sun sign effect in such a huge sample. As shown in the figure below, the results show no clear conformity to what astrology predicts. Days between 16 million French couples' birthdays from Castille converted to approximate sun signs between spouses. Once again the ups and downs are all over the place. The above results show a small consistent deficit of squares 90 but no consistent excess of sextiles 60 or trines The apparently large excess of same-sign couples shown in red appears large only because the scale is small; thus the corresponding effect size is a tiny 0.
So this enormous sample offers no useful support whatever for sun sign effects.
The excess of same-birthday and same-sign couples is highly significant, but according to Castille an explanation "is yet to be found" page Voas notes that although the quality of the data is very good, three factors can upset any study: 1 Variations due to chance. Some people may not know their birthday or the birthday of the person they are completing the form for. Others may make mistakes, or write illegibly, or decline to respond, or lie.
Some sign pairings may occur more frequently than expected if people seek these matches and avoid others.
Zodiac Love Compatibility: Which Signs to Date — and Which to Avoid
The Thomas theorem in sociology holds that if people perceive something as real, even if it isn't, it will have real consequences, as when the 17th century belief in witches led to many thousands of innocent people being burned at the stake. Fortunately it is possible to allow for the above factors.
For example post-census surveys and quality checks provide information about response and non-response, while self-attribution and genuine sun sign effects can be disentangled by testing only people without knowledge of sun sign compatibilities. Voas also notes that more than a hundred standard tables summarising the census results have been published.
If they do not cover a particular interest, special tables can be commissioned including any of the data collected, subject to the usual considerations of data protection. Once a table has been created it becomes publicly available. In this case a table showing the pairings by sun sign of 10,, married couples in England and Wales had already been commissioned by someone describing himself as "a philosopher with a degree in statistics" who was "investigating the truth behind astrology".
The table was in general agreement with the results of Castille. It appeared to show a small but significant tendency for people to marry partners of the same sign about 22, more than the , expected , and a smaller tendency to marry adjacent signs, but no clear conformity to what astrology predicts. Nevertheless the significant excess of same-sign couples seemed large enough to justify investigation. So Voas commissioned a full breakdown of husbands and wives by day and month of birth days x days x four subgroups by husband's age, or nearly , combinations.
As shown in the figure below, this new data showed an apparent month effect that was slightly larger than the apparent sign effect. So both effects were largely due to couples with matching birthdays. Results from Voas The excess of same-month couples 2. Voas notes that, while some people may be drawn to each other because they have the same birthday, the excess of same-birthday couples is probably largely due to response error.
Census forms are typically completed by one member of the household, who through carelessness or forgetfulness may enter their own birthday for that of their spouse. Such errors are supported by a census validation study that found 10, couples where one spouse had assigned their own sex to the other. If people can make mistakes about their spouse's sex they can also make mistakes about birthdays.
proxy.littlelives.com/you-can-teach-your-children-math-middle-elementary.php Indeed, the most common birthday was 1 January vs 77 expected with 1 July in second place, indicating that some people entered 1 January or 1 July if an exact birthday was not known, a practice known to occur in old people's homes and for people born overseas. Recall that Castille observed the same in French data, and the same is visible in the previous plot of Sachs's data. There were even more opportunities for the adjustment of birth dates in the 18th and 19th centuries, see The Gauquelin work 2.
Opinions, artifacts, puzzles on this website under Gauquelin. Furthermore, more spouses than expected were listed as sharing the same day of birth but a different month or the same month of birth but a different day as the other spouse. This is not necessarily relevant to the analysis of sun signs, although it would be relevant to Castille's day counting, but it does illustrate the way in which recording errors can occur.
A crucial disentangling test Back at the excess of same-month couples, Voas wondered if despite the positive effect of recording errors there might still be some kind of seasonal affinity and if it could be astrological. Nevertheless, it constitutes interesting quick pieces of information about your affinities, since it incorporates all the specifics of your respective approximate natal charts.
