Brief historyThese tests, initiated in the 1950s by Michel Gauquelin, followed 3 directions :
- tests on professional groups,
- tests on heredity,
- tests on character traits.
The assertions of Gauquelin and followers are : One particular effect - the repartition of Mars in the births of sportsmen, called "the mars effect" - gave rise to very long polemics without any consensual conclusion. Very few members of the academic world studied the question, most notably Suitbert Ertel and Arno Müller. Ertel introduced citation count, providing an objective measure of eminence, and analyzed Gauquelin and skeptic tests.
The story ended in 1996 with two publications:
- The "Mars Effect", A French Test of Over 1,000 Sports Champions, describing the third test conducted by a group of skeptics (CFEPP), and concluding to an abscence of statistical anomaly.
- The Tenacious Mars Effect, by Suitbert Ertel, concluding that statistical anomalies can be observed and that the negative results of skeptic groups are due to data manipulation.
Why Gauquelin5 ?There are several reasons to care about the data used to perform statistical tests on astrology :
ScientificHistory is so confused that the question to know if these statistical anomalies exist out of human bias is still open.
We today have the means to reproduce these tests with better and more reliable data, and see if a consensus can emerge.
This is possible for two reasons :
- The availability of online civil registries permits to check birth times and correct historical data.
- Internet provides many ways to rank famous persons by eminence.
HistoricalHistory of science is concerned, to study the attitude of the scientific community towards the claims of Gauquelin.
TechnicalThese data are interesting because they contain birth time. And birth times are generally neglected in the web. Take for example wikidata : birth times are set to
00:00:00. There is no way to make the difference between "this is a date with no time information" and "this is a date with time = 00:00:00" (maybe there is a way, but I didn't find it).
Birth times of persons better the web, give it more precision and can be useful for other disciplines studying human activity.

This documentation is written in a globish as close as possible to english, but uses french conventions for capitalization, spaces and large numbers :
- Names of months, weekdays, languages etc. are not capitalized.
- The characters ; ? ! are preceeded and followed by a white space.
- White space is used as separator for large numbers (for example one million is written 1 000 000).
- Marriage is written mariage, address is written adress.
This software has a slow development pace because I do it on my spare time.
