Polar meridians

The first part of this series (Wackford 2000/2001) was written as a one-off paper concerned only with the trigonometric determination of the angles in a circumpolar horoscope. As such it did not fully explore issues of upper and lower culmination, leaving instead an open question that will now be addressed. This paper continues examination of the semi-arc system (North 1986, Wackford 2002/3b), its applicatioin in the Polar regions and relationships between this method and the diurnal and seasonal cycles.

“Three tests, three hits”. Whose hits? Scrutinies of Geoffrey Dean’s parental tampering claim (5)

Geoffrey Dean gave an account of three tests of his Parental Tampering Hypothesis (PTH) that I had suggested to him that he conduct. He concluded (Dean 2000): “Three tests, three hits. I rest my case.” I scrutinised Dean’s procedure and found that his first test failed to support PTH (about planetary effects on desired days). He obtained the desired hit by reversing the hypothesis post hoc so as to accommmodate the new “prediction” to his result. The second test also had negative results (about a purported dependence of planetary effects on “seeing conditions” at the time of birth). Again Dean reversed his critic’s hypothesis so as to make a hit out of this failure. The third test failed no less (about combining all informative planetary effects rather than suing the dominant effect only). Dean obscured his actual finding. In sum, the three tests failed to prvide evidence for PTH. The present result is consistent with those of four earlier scrutinies. No further test is necessary to conlcude that Dean’s claim that Gauquelin effects are man-made artificact is utterly mistaken.

The influence of the Chinese zodiac on fertility in Hong Kong SAR

The annual total of births fell substantially in Hong Kong in the past 20 years, and the average fertility level of 0.9 births per family has now fallen below the notional replacement rate for the existing population. Nevertheless, short run periods of high birth rates have occurred, particularly in the Dragon Years of 1988 and 2000. This rise in fertility may be related to zodiacal beliefs about fertility and the presumed favourable time for births, but this needs to be investigated more systematically.

Astrological birth signs in suicide: hypothesis or speculation?

The majority of those who read their ‘star signs’ can identify aspects of their personality in what they read and it is possible that this may influence their attitudes and actions. The research literature has neglected astrological signs as possible predictors of suicidal behaviour and ideas. To see whether astrological birth signs are associated with suicide and method used, data were collected from the Public Healh Department in North Cheshire on Coroner’s verdicts of suicide and open verdicts in all deceased aged 60 and above between 1989 and 2000. The timing of suicide deaths was compared with those occurring from natural causes. Most of the comparisons were not statistically significant, except for suicide by hanging, which was significantly elevated in those with a birth sign in Virgo, and lowest in those born in Saggittarius and Scorpio. In addition suicide by violent methods showed a significant excess in thos born in summer months.

Mes premieres analyses scientifiques en astrologie medicale

My first scientific analyses in medical astrology tested traditional astrological hypotheses (especially the correspondence of the signs of the zodiac with parts of the body, starting from the head down to the feet), which when scientifically tested, do not seem to be confirmed … among 423 patients. The … use of a pathology coding system, required for statistical study, could make further collaboration possible.

From medical astrology to medical astronomy: sol-lunar and planetary theories of disease in British medicine, c. 1700-1950

After 1700, astrology lost the respect it once commanded in medical circles. But the belief that the heavens influenced bodily health persisted – even in learned medicine – until well into the nineteenth century. The continuing vitality of these ideas owed much to the new empirical and mechanical outlook of their proponents. Taking their cue from the work of Robert Boyle and Richard Mead, a number of British practitioners amassed statistical evidence which purported to prove the influence of the moon upon fevers and other diseases. Such ideas flourished in the colonies and in the medical servives of the armed forces, but their exponents were not marginal men. Some, like James Lind were widely respected and drew support for their views from such influential figures as Erasmus Darwin.

Planetary Influences

The Mars effect discovered by Michel Gauquelin in the charts of sports
champions is discussed and the controversy this engendered from other scientific quarters is briefly summarised. A summary of the work of Ertel in replicating the Gauquelin study is presented and the author asserts that the Mars effect holds good for people at the top of other professions. The Fourier method of analysing the Mars effect is presented as a more effective way of understanding this phenomenon.

Shift control of synastry effect

I conducted a refinement of the synastry control experiment (1) in which the birth dates of married partners were shifted 1, 2, 3, 4, 5 and 6 days The surplus of aspect frequency gradually decreased with increasing shift magnitude. The maximum frequency appears at the zero shift. These findings reinforce the conclusion that the previously reported synastry effect is not due to methodological errors.

Indication for a role of synastry aspects in a Gauquelin-sample of 2824 marriages (1)

In this study I tested the astrological claim that synastry aspects between two natal charts play a role in human relationships. The sample used contained the birth data of 5648 parents who were non-celebrities born in France around the turn of the century. These birth data had originally been collected and published by M & F Gauquelin. To test this synastry claim I counted and analysed the mutual major aspects between partners (angular separation along the ecliptic) of 0, 60, 90 120 and 180 degrees (orb 5 degrees) of nine natal horoscope factors (Sun, Moon, Mercury,Venus, Mars, Jupiter, Saturn, Asc. And MC). I derived the theoretically expected aspect frequencies from the sample by comining all male subjects with all female subjects, each gender belonging to specific age groups. To test the significance of the deviation between observed and expected aspect frequencies, I used the synasstry aspects in 500 samples of each 2824 randomly composed couples, and fitted probability-density functions to the frequency histograms of these data. The frequency of the grand total of aspects appeared to be significantly large. A genuinely significant high aspect frequency to the Sun in the charts of the wives took a heavy share in the surplus of the grand total. Hwever, the number of significant aspects as well as the magnitude of the overall deviation from chance level were not genuinely significant. Nevertheless, a significant majority of factor pairing showed a surplus of aspect frequency. In addtion, several combinations of aspects as well as their frequency orb dependencies did not falfify astrological doctrines on synastry. But since th effect sizes were very small the conclusion was that synastry aspects may play only a trivial role in partner selection.
