For those less interested in political wranglings among skeptics and
more interested in examining the scientific data vis a vis the relation
of Mar's position at birth to success as an athlete, I include the
following (non-exhaustive) list of references to scientific articles
on the Gauquelins' "Mars effect"; for those who do not know, this was
only one of many findings by the Gauquelins:
The original work:

and Sports Champions." Laboratoire d'Etude des Relations Entre Rythmes
Cosmiques et Psychophysiologiques (LERRCP), 8 Rue Amyot, Paris 75005, France.

co-varies with eminence. Journal of Scientific Exploration, Vol. 2, pp. 58-82.

Replication. Series D: Scientific Documents, Vol. 6. Paris: LERRCP.

re-analysis and new investigations on the same material. Correlation,
Vol. 4, pp. 8-24.
Unfortunately, the only reference I can find for the replication of the
effect by the Belgian Committee for the Scientific Study of Paranormal
Phenomena (who obtained an effect with a probability less than .01, that
is, the effect could occur by chance 1 in 100 times in a Chi-squared
analysis) is: Dean, G. (1977). Recent advances in natal astrology: a
critical review 1900-1976 (pp. 384-385). Southampton: Camelot Press.
Dean comments that: "[the same effects] were duplicated independently
by the very highly skeptical Belgian Committee for the Scientific Study
of Paranormal Phenomena (a committee composed of leading scientists) using
an independent sample of 535 Belgian sportsmen." (p. 385)
