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.

The distribution over the diurnal cycle of Sun, Moon, Mercury, Venus, Mars, Jupiter and Saturn was computed for both genders of 2824 Gauquelin couples. I found that the distributions of the five “Gauquelin planets” in combination are significantly different between the two genders. Wives have a higher frequency of planets near the Ascendant, especially of Venus.

John Nelson has claimed that heliocentric planetary aspects are an important factor in predicting short-wave radio disturbance. But a correlation analysis of his predictions and observed radio quality showed that the claim was not substantiated. In assessing his own predictions, Nelson used a method of anlaysis that gave an accuracy of around 90%. This is shown to be an artifact arising from the high proportion of undisturbed days. A valid system of predicting must do better than both chance and baseline conditions, but on the basis of conventional statistical tests Nelson’s planetary system does not.

Modern scientific research and astrology are different kinds of activity. Astrology is derived from given Principles, research from theory and empirical data. The author argues that the two activities come from different world-views and one cannot validly be regarded in the light of the other. Questions about the direction of astrological research are posed.

A study of the accuracy of “ancient” astrologers’ keywords on planetary temperaments is reported, using astrological material different from that used by Francoise Gauquelin in her study (Traditional Symbolism in Astrology and the Character traits method, LERRCP, Paris, 1980). The astrology of “ancient” authors who lived in Elizabethan times or before was tested. Its accuracy was evaluated using 50,000 character traits systematically collected from the biographies of 2000 successful subjects. Results strongly suggest that “ancient” astrologers are doing as well as the modern ones. The results seem to vinidicate the idea that the origin of the astrological planetary temperaments is very old and probably far more ancient than the “ancient” astrological keywords investigated.

Previous attempts to quantify the agreement between astrologers’ keywords for the planets and the Gauquelins’ independently derived lists of planetary traits have been marred by the use of less than ideal data. A fresh analysis, with new data and a different method, is presented here. The results show quite high, non-random agreement, especially for Mars, Saturn and Moon though arguments are also presented for regarding the measurements as only rough estimates. Improvement in astrologers’ accuracy over time was anticipated but the evidence supporting it was slight.

The author’s previous research with M. and F. Gauquelin data confirmed the existence of planetary effects for eminent professionals. However, the present research casts doubt on Gauquelin’s physical explanation. (1) For sports champions the planetary effect was unrelated to astronomical variables (distance of Mars from Earth, its angular size, apparent magnitude, declination, right ascension, solar elongation, and radius vector). Further, the effect did not diminish during Mars-Sun conjunctions. (2) For ordinary people, Gauquelin’s claim that geomagnetic activity enhanced the planetary correspondence between children and parents was not supported. Nor did the planetary effect for eminent professionals covary with geomagnetic activity. lt seems that Gauquelin’s positive results with geomagnetism are due to random oscillations. (3) Gauquelin’s claim that planetary effects decrease after 1950 – a presumed side-effect of applying obstetric drugs – could not be veried with professionals’ data. However, the number of post-1950 births was insufficent for a definite conclusion. (4) The accuracy of birth times on official documents increased markedly through decades 1830 – 1950 but produced no corrresponding increase in planetary birth frequencies. In the light of these results, Gauquelin’s midwife hypothesis, seems to be untenable, in which case an interpretation of planetary effects in terms of physics and physiology must be replaced by something else.

An exploratory investigation is reported in which physiognomic evidence for seasonal alternant-sign periodicity with predictable directionality was sought in the photographic portraits of Caucasoid and Negroid males. The portraits, which were taken from published biographical directories that also list birth dates, were examined for specific physiognomic traits that were postulated to be characteristic of either the odd-numbered sun signs (or solar months), traditionally associated with extraversion (E), or the even numberred sun signs, associated with introversion (I). The results are corroborative, but the method is not without its shortcomings: (1) the test instrument, which consists of several thousand small photographic portraits mounted on 3 x 5 inch cards, required much time and effort to prepare and cannot easily be reproduced for replication studies; (2) judges with sufficient talent and motivation to learn face reading are rare; (3) despite repeated efforts, a unitary physiognomic trait capable of dichotomizing the protratis was not found and it was only by weighing several traits in each face simultaneously that significant scores could be achieved; (4) the proprotion of photographic subjects with prototypic faces is small (less than 10% for each polarity); (5) a small but significant excess of smiling faces was found among the E sign portraits, so the possibility of cueing by astrologoically sophisticated photographic subjects cannot be excluded.

Precision of birth time recordings greatly increases between 1800 – 1950, while key sector percentages do not. This puzzling lack of a correlation is somewhat weakened by three additional observations possibly indicating an effect of record precision in different ways.
