As the polarized arguments over quantitative versus qualitative research have drug on and on and on, ad nauseum, the point that seems to arise repeatedly is that qualitative research has developed as a paradigm in recent years due to the biased, mechanical one-dimensionality and potential superficiality that quantitative methods sometimes, due to their very nature, have yielded.  Contemporary scholars in most any field that involves study of human nature recognize that qualitative research studies are essential to counterbalance the mechanistic biases of quantitative methods.Both have their functional value when both carried out and interpreted effectively.Astrology is a broad field with sub-specializations.One research model may be more appropriate for measuring psychological factors; another for sociological factors; another for medical factors; and still others for financial or other factors.  Nothing would delight reactionary critics of astrology more than to see astrologers wasteenergies arguing over quantitative/qualitative or psychological/physical polarities, instead of proceeding to conduct further research according to the method of choice, contributing something constructive to astrology and to society.The most effective goal and use of astrological research may well be to refine, prioritize, and sort out existing techniques; for the general public, including numerous people in academic circles, have little doubt that many astrological claims make sense.It is the verification of which techniques and interpretive guides are the most accurate and effective that will increase both the competence and credibility of astrologers.

This bibliography includes studies by astronomers, astrologers, and statisticians, containing varying degrees of skepticism and criticism of astrological theories and practices.All of them are worthy of consideration in building an understanding of which components of astrology are most likely to be questioned by the detached observer, and which points in our field need to be clarified in order to increase precision, accuracy, and credibility.

Seymour, Percy (1992).THE SCIENTIFIC BASIS OF ASTROLOGY.New York NY: Saint Martin's Press.In this book, Percy Seymour, PhD Astronomy, PhD Astrophysics, of the Plymouth Polytechnic Institute, summarizes repeatedly observed correspondences between planetary cycles, changes in the Earth's magnetic field, and other natural phenomena that would verify astrology's validity, and makes the reader wonder why resistance to astrology's credibility still exists.

Culver, Roger & Ianna, Philip (1988).ASTROLOGY: TRUE OR FALSE?.Buffalo NY: Prometheus Books.A highly critical assessment of astrology and astrological research.This book gives examples of what critics of astrology use to discount it.It points out what issues need to be addressed in encountering critics; it is not intended to be a book that unquestioningly endorses astrology or astrologers.It is similar to other books in that it points out areas where astrology needs further research.

Dean, Geoffrey & Mather, Arthur (1977).RECENT ADVANCES IN NATAL ASTROLOGY.Subiaco, Western Australia: Analogic.The subtitle of this book is "A Critical Review, 1900-1976", and indeed the book is so critical that it set a lot of astrologers off fuming.What this book did for astrologers, positively, is give a very broad and coherent compilation of 20th century astrological research, and make us critically aware of all our vulnerable spots.It gives valuable insights into modern history of astrological research, into the pitfalls of poor to worthless quantitative research design, and preparatory information to be ready for critics of Astrology.If you are picking up the book for the first time, brace yourself for everything you think you know about Astrology to be questioned... on several occasions, the compilers/editors played devil's advocate and drew some rather heavily biased conclusions from data... perhaps to challenge us to further prove what we assume to be true.As of July 2000, the book is unfortunately out of print but may be found through used book locators.Don't expect to see astrology proven by this book; do expect to see a good bibliography of research studies, where to find them, and what they are most likely to be criticized for. Remember, the cards of the conservative academic establishment's deck were stacked against Astrology for quite some time in the past.

Gauquelin, Françoise (1982).PSYCHOLOGY OF THE PLANETS.San Diego CA: Astro Computing Services.A summary of the extensive renowned research performed by Françoise and her husband at that time, Michel Gauquelin. This particular book gives a general summary of the research methodology used and the results of comparing the research with traditionally ascribed planetary characteristics, verifying traditional assumptions about the basic character of the planetary energies of the Moon, Venus, Mars, Jupiter, and Saturn. "Those who believe in astrology will probably consider the conclusions of this study terribly obvious.... For the first time, scientific proof of the existence of the astrological reality of some of the planetary symbols has been clearly demonstrated."

Nolle, Richard.CRITICAL ASTROLOGY -- INVESTIGATING THE COSMIC CONNECTION.Tempe AZ: American Federation of Astrologers.Addresses the need for critical astrology; Is astrology ready for its own future?; Three steps to research; The need for historical research in astrology; Adapting statistical methods to astrology; Basic statistical astrology techniques; Problems and perspectives in astrological research; Science or psience?; A hole in harmonics; Has tropical astrology had it?; Mars sign and aircraft disaster.

Pottenger, Mark, ed. (1995).ASTROLOGICAL RESEARCH METHODS -- AN I.S.A.R. ANTHOLOGY.Los Angeles CA: International Society for Astrological Research (ISAR).A substantial anthology of articles onastrological research, with broadly varying convictions about what research is and how it is to be done.A central, comprehensive, must-read book for any astrologer seriously interested in research issues. Articles by Françoise Gauquelin, Charles Harvey, Mark Urbain-Lurain, T Patrick Davis, Mavis Klein, J Lee Lehman, Jane Lee, Douglas Kyle Pierce, Lois M Rodden, Ronald B Tiggle, Mark Pottenger, Mike O'Neill, Suitbert Ertel, Theodor Landscheidt, Frank McGillion, Graham Douglas, Raymond A Merriman, Geoffrey Dean, Nicholas Kollerstrom, and Peter Roberts.

Aveni, Anthony (1992). CONVERSING WITH THE PLANETS: HOW SCIENCE AND MYTH INVENTED THE COSMOS.New York: Times Books. This information-intensive and scholarly book addresses the merging of scientific paradigms with the humanities.Dr Aveni, professor of archaeology and astronomy, raises the question of the role science plays and is to play in the future, and writes an extensive account of the development of astrology that interrelates the physics of the planets with the mythology and symbolism of the planets.While the book does not address research methodologies in detail, it is a must-read in order to gain a balanced perspective on where astrology has come from, and where it is headed in the future.Dr Aveni presents interesting background on non-European astrologies, particularly the Mayan and Babylonian.

There is broad variation among the following links, ranging from strong empirical emphases, to flat rejection of empirical research, to emphases on the need to develop new approaches to both research design and perhaps more significantly than these issues, data interpretation.

On the research of Professor Suitbert Ertel, Ph.D. Psychology, University of Göttingen, verified the research of French analysts Françoise and Michel Gauquelin in the face of clownish and manipulative attacks on their research.

Astronomical Contributions to Research on the Nature of Astrological Phenomena by Irina Predeanu, Ph.D. Mathematics/Astronomy: In this article, which originally appeared in French in the RAMS astrological research journal, Dr Predeanu eloquently presents current scientific realities which validate standard astrological assumptions.Such writings dispel doubt of the link between astronomy and astrology and the rationality of astrological principles, despite the last remnants of diehard skepticism among both astronomers and astrologers.
