The forces described by astrology may not have any significant effect on
humanity, but the institution of astrology does have a strong influence.
It effects the views of a large part of the population toward science and
logical thought. The wife of a recent president scheduled important
government actions and decisions based on the predictions of an astrologer
(Read "Stranger in a Strange Land"). The Ed Sullivan worshippers, if there
are any, have much less influence on human society. Since astrology makes
claims about the future, its validity can be tested to some extent by
statistical analysis. In particular, it is plausible to infer that base
hits, which are of great personal importance to professional players, ought
to be influenced by the "astrological forces", as shown by correlation with
some astrological phenomenon, if these forces indeed have considerable
influence over human existence, as claimed by the astrologers. (The test
is more valid if it is established in advance that the players are unaware
of any astrological predictions while they play.) If someone is willing
to undertake this job at his own expense, it would appear that he is
performing a valuable service.

A similar experiment was performed a year or two ago, to determine whether
a specific cryogenic treatment would improve the mechanical properties of
tool steel. Test subjects used treated and untreated tools, without knowing
which was which, with the net result that no significant improvement was
found. Assuming test conditions were properly controlled, I would consider
this a legitimate scientific inquiry.

By the way, the moon, by providing variable illumination at night and
influencing the tides, has a demonstrable influence on animal and human
activity, on a month-by-month basis.
