| "'''Abstract''' - [http://en.wikipedia.org/wiki/Gauquelin '''Gauquelin'''] claimed that there is a statistically significant correlation between the positions of Mars and the times and places of birth of sports champions. Independent scientists have attempted to replicate this hypothesis without success. We provide a brief history: the Comité Para, the Zelen and U.S. tests, and a recent French test. Ertel and Irving, in sifting through the data, attempt to rescue Gauquelin's thesis. Ertel introduced his "eminence test", and Ertel and Irving their "IMQ bias indicator." However, they presuppose what they set out to prove. We conclude that there is insufficient evidence for the "[http://en.wikipedia.org/wiki/Mars_effect '''Mars effect''']", and that this effect may be attributed to Gauquelin's [http://en.wikipedia.org/wiki/Selective_bias '''selective bias'''] in either discarding or adding data post hoc."
