Suitbert Ertel (b. 2 March 1932, Radevormwald, Rhein-Wupper-Kreis, Germany) is an eminent statistician and psychologist. He is Professor Emeritus of Georg-August-University of Göttingen, Germany. Since 1976, his systematic and investigative studies into unorthodox fields relating to psychology have led to controversy in particular with the astrological evidence from French statistician, Michel Gauquelin and the Carlson Test.

Academic History

Ertel obtained his Ph.D. in Psychology at the University of Münster in 1963. In 1971, he became Professor of Psychology at the University of Göttingen.



Areas of Research

Initially his studies focussed on psycho-linguistics, personality and individual and cultural differences. From 1976, his studies moved into investigation and testing claims in the field termed para-psychology. These included solar activity in relation to human behaviour, the morphic resonance claims of Dr Rupert Sheldrake and astrological phenomena such as the Gauquelin effect and more recently the renowned Carlson Double Blind Astrology Experiment.

Research into Gauquelin & the Mars Effect

In 1985, Ertel started an investigation into one of several claims by French statistician, Michel Gauquelin. Gauquelin claimed there was a correlation between the position of Mars at birth and eminence within certain fields. Ertel demonstrated that the effect was highly significant and to a level that could not be accounted for by chance factors.

"It is concluded that in view of the evidence corroborating the mars effect, 40 years after its first claim by Michel Gauquelin (1955), the phenomenon demands recognition as scientific fact by the skeptic committees as well as by mainstream science." ~ Suitbert Ertel. The Tenacious Mars Effect (1996) p.SE-2

Ertel co-wrote, The Tenacious Mars effect (1996), with American researcher and editor, Kenneth Irving. In this publication, they were able to publish the extensive results and to document the history of the dispute between Gauquelin and his critics among sceptical groups in France, Germany and CSICOP in the USA.



Unable to account for these extraordinary results, sceptical organizations such as GWUP Gesellschaft zur Untersuchung parawissenschaftlicher Phänomene (Society for the Study Paranormal Phenomena) claimed that Ertel, a psychologist favoured astrology to the extent that he must have deliberately manipulated the results. However, Ertel refuted this by showing that he was well-known for discovering errors in Gauquelin's data and statistical analysis in the past. Nevertheless, when the accumulated results from all the sceptical groups were compiled with Gauquelin's 'clean' data, the combined results showed the Mars Effect to be even more significant than Gauquelin's original claims. To date, no one has been able to account for these results which appear to suggest that astrology may have a scientific basis.



An ardent critic of astrology and CSICOP fellow, Geoffrey Dean has claimed that parents in various countries must have deliberately falsified the birth times of their children. There is no evidence to support his claim. What is mystifying is why would any parent go to the trouble to ensure that Mars, a planet that was at the time considered 'malefic' was located on one side of an angle in their child's horoscope. To date, no one has taken Dean's theory seriously.



Randi Million Dollar Challenger

Ertel appproached James Randi with a view to testing the statistical results of the Gauquelin planetary effects as evidence to claim the Million Dollar prize. However, since the sample would need at least one thousand birth charts and considered analysis, Randi felt he would be unable to handle this type of challenger. Randi has admitted that he is hopeless at statistics and his tests are mainly based on practitioner's performance rather than detailed analysis required by astrological research. [3]

[2] Tenacious Mars Effect, Ertel & Irving (1995) About the Authors
[3] "My first approach [to Randi] was made because I thought the prize might be achieved by the Gauquelin planetary effect, a statistical "paranormal" or "neo-astrological" effect, with which I was very familiar as researcher. The problem was that decisions regarding the sample which would amount to 1000 natal charts was dependent on much informed thought, and Randi didn't know how to deal with the conditions. So the correspondence came to an end." ~ Suitbert Ertel [ ]
