Philosophy of Archive
Includes aims, history, how to contact us

Abstract -- The archive provides readable articles on scientific research into astrology that are also sensitive to astrology's merits. The authors are mostly researchers who, unlike astrologers, have no vested interest in the outcome. Articles are rigorous, impartial, and have passed peer review. All have abstracts to save your time. All are in plain English. The archive began in July 2000 and receives over 15,000 visitors a year. Currently it has 75 articles totalling half a million words (over 32 hours of reading). Our email address is in the Netherlands, see text for details. We welcome your comments. All comments will be acknowledged.

Astrology has been tested in more than 600 scientific studies. But the results are rarely mentioned in astrology books or on astrology websites, nor are they treated fairly by debunkers. For most people the results are hard to find. So this archive was started in July 2000 by former astrologer Rudolf H Smit from Zwolle in the Netherlands. The aim is to provide articles related to scientific research into astrology. The authors are mostly researchers who, unlike astrologers, have no vested interest in the outcome.

On this website you will find articles sensitive to astrology's merits as well as articles devoted to its scientific exploration. Articles are rigorous, impartial, and have passed peer review. All have abstracts to save your time, all are in plain English, and all are indexed for easy retrieval because in this archive the reader's interest comes first. Until 2010 the articles were updated as needed, but updating has been largely discontinued because (1) the picture is unlikely to change, and (2) hard copy is more convenient -- as in this new book:

The design of the archive website began in late 1999. The name was secured in February 2000 and the first astrology-and-science website went online in late July 2000 with 10 articles. By 2008 the number of articles has grown to 70. During the next five years articles were updated or discontinued, and others were added. By 2013 there was a total of 75 articles, a total of half a million words taking more than 32 hours to read. In 2013 the archive website was redesigned and made easier to use.

Number of articles
Number of articles in the present archive 2000-2013

Fog level
Article length is generally between 1000 and 15,000 words. The average is 7500 words, which takes 30 minutes to read at the average student reading speed of 250 words per minute. The longest article (Interview with researchers) has 42,000 words. Reading difficulty is generally between 10 and 12 as measured by Gunning's Fog Index (Gunning R The Technique of Clear Writing McGraw-Hill 1952:34-39). The index is roughly equal to the grade level required for 90% comprehension. For comparison 6 is required for comics, 9 for Reader's Digest, and 14 for 61+encyclopedias. 12 is the average reading comprehension level of 17-year-olds. On this website no article exceeds 13.

A counter was added in September 2000. After two years the site had received more than 10,000 visitors mainly from North America and Europe. In 2008 it received its 100,000th visitor and its 150,000th in late 2011. Currently it receives more than 15,000 visitors a year.
