The exact demarcation of what a constellation is, is cultural, and varied between civilisations. This provided a further motivator for the study of astronomy. During the Islamic Golden Age , astronomy was funded so that the astronomical parameters, such as the eccentricity of the sun's orbit, required for the Ptolemaic model could be calculated to a sufficient accuracy and precision.
Those in positions of power, like the Fatimid Caliphate vizier in , funded the construction of observatories so that astrological predictions, fuelled by precise planetary information, could be made. The clear rejection of astrology in works of astronomy started in , with the yearly publication La Connoissance des temps. On astrology, it cited the inability of different astrologers to make the same prediction about what occurs following a conjunction , and described the attributes astrologers gave to the planets as implausible.
Astrology provides the quintessential example of a pseudoscience since it has been tested repeatedly and failed all the tests.
Science and non-science are often distinguished by the criterion of falsifiability. The criterion was first proposed by philosopher of science Karl Popper. To Popper, science does not rely on induction ; instead, scientific investigations are inherently attempts to falsify existing theories through novel tests.
If a single test fails, then the theory is falsified. Therefore, any test of a scientific theory must prohibit certain results that falsify the theory, and expect other specific results consistent with the theory. Using this criterion of falsifiability, astrology is a pseudoscience. Astrology was Popper's most frequent example of pseudoscience. In contrast to scientific disciplines, astrology does not respond to falsification through experiment. According to Professor of neurology Terence Hines , this is a hallmark of pseudoscience. In contrast to Popper, the philosopher Thomas Kuhn argued that it was not lack of falsifiability that makes astrology unscientific, but rather that the process and concepts of astrology are non-empirical.
Rather, in Kuhn's eyes, astrology is not science because it was always more akin to medieval medicine ; they followed a sequence of rules and guidelines for a seemingly necessary field with known shortcomings, but they did no research because the fields are not amenable to research,  : 8 and so, "They had no puzzles to solve and therefore no science to practise. While an astronomer could correct for failure, an astrologer could not. An astrologer could only explain away failure but could not revise the astrological hypothesis in a meaningful way.
As such, to Kuhn, even if the stars could influence the path of humans through life astrology is not scientific. Philosopher Paul Thagard believed that astrology can not be regarded as falsified in this sense until it has been replaced with a successor. In the case of predicting behaviour, psychology is the alternative. Progress is defined here as explaining new phenomena and solving existing problems, yet astrology has failed to progress having only changed little in nearly years.
For these reasons Thagard viewed astrology as pseudoscience. To Thagard, astrology should not be regarded as a pseudoscience on the failure of Gauquelin's to find any correlation between the various astrological signs and someone's career, twins not showing the expected correlations from having the same signs in twin studies, lack of agreement on the significance of the planets discovered since Ptolemy's time and large scale disasters wiping out individuals with vastly different signs at the same time.
While verification and falsifiability focused on the theory, Kuhn's work focused on the historical context, but the astrological community should also be considered. Whether or not they:  : — In this approach, true falsification rather than modifying a theory to avoid the falsification only really occurs when an alternative theory is proposed. For the philosopher Edward W.

James, astrology is irrational not because of the numerous problems with mechanisms and falsification due to experiments, but because an analysis of the astrological literature shows that it is infused with fallacious logic and poor reasoning. What if throughout astrological writings we meet little appreciation of coherence, blatant insensitivity to evidence, no sense of a hierarchy of reasons, slight command over the contextual force of critieria, stubborn unwillingness to pursue an argument where it leads, stark naivete concerning the efficacy of explanation and so on? In that case, I think, we are perfectly justified in rejecting astrology as irrational.
Astrology simply fails to meet the multifarious demands of legitimate reasoning. This poor reasoning includes appeals to ancient astrologers such as Kepler despite any relevance of topic or specific reasoning, and vague claims. The claim that evidence for astrology is that people born at roughly "the same place have a life pattern that is very similar" is vague, but also ignores that time is reference frame dependent and gives no definition of "same place" despite the planet's moving in the reference frame of the solar system.
Other comments by astrologers are based on severely erroneous interpretations of basic physics, such as a claim by one astrologer [ who? Further, James noted that response to criticism also relies on faulty logic, an example of which was a response to twin studies with the statement that coincidences in twins are due to astrology, but any differences are due to "heredity and environment", while for other astrologers the issues are too difficult and they just want to get back to their astrology. From the Quinean web of knowledge, there is a dichotomy where one must either reject astrology or accept astrology but reject all established scientific disciplines that are incompatible with astrology.
Astrology and science
Astrologers often avoid making verifiable predictions, and instead rely on vague statements that let them try to avoid falsification. When specific predictions from astrologers were tested in rigorous experimental procedures in the Carlson test, the predictions were falsified. The Shawn Carlson's double-blind chart matching tests, in which 28 astrologers agreed to match over natal charts to psychological profiles generated by the California Psychological Inventory CPI test, is one of the most renowned tests of astrology,   and was published in a highly prestigious journal, Nature.
Scientist and former astrologer Geoffrey Dean and psychologist Ivan Kelly  conducted a large-scale scientific test, involving more than one hundred cognitive , behavioural , physical and other variables, but found no support for astrology. A meta-analysis was conducted, pooling 40 studies consisting of astrologers and over 1, birth charts. Ten of the tests, which had a total of participating, involved the astrologers picking the correct chart interpretation out of a number of others that were not the astrologically correct chart interpretation usually three to five others.
When the date and other obvious clues were removed, no significant results were found to suggest there was any preferred chart. In 10 studies, participants picked horoscopes that they felt were accurate descriptions, with one being the "correct" answer. Again the results were no better than chance.
In a study of sets of people born within 5 minutes of each other "time twins" to see if there was any discernible effect, no effect was seen. No effect was seen. In , astrologer  and psychologist Michel Gauquelin stated that although he had failed to find evidence to support such indicators as the zodiacal signs and planetary aspects in astrology, he had found positive correlations between the diurnal positions of some of the planets and success in professions such as doctors, scientists, athletes, actors, writers, painters, etc.
Geoffrey Dean has suggested that the effect may be caused by self-reporting of birth dates by parents rather than any issue with the study by Gauquelin. The suggestion is that a small subset of the parents may have had changed birth times to be consistent with better astrological charts for a related profession.
The sample group was taken from a time where belief in astrology was more common. Gauquelin had failed to find the Mars effect in more recent populations, [c] where a nurse or doctor recorded the birth information. The number of births under astrologically undesirable conditions was also lower, indicating more evidence that parents choose dates and times to suit their beliefs.

Beyond the scientific tests astrology has failed, proposals for astrology face a number of other obstacles due to the many theoretical flaws in astrology  : 62  : 24 including lack of consistency, lack of ability to predict missing planets, lack of any connection of the zodiac to the constellations, and lack of any plausible mechanism.
The underpinnings of astrology tend to disagree with numerous basic facts from scientific disciplines. Testing the validity of astrology can be difficult because there is no consensus amongst astrologers as to what astrology is or what it can predict. Georges Charpak and Henri Broch dealt with claims from western astrology in the book Debunked! ESP, Telekinesis, and other Pseudoscience. They commented on the example of Elizabeth Teissier who claimed that "the sun ends up in the same place in the sky on the same date each year" as the basis for claims that two people with the same birthday but a number of years apart should be under the same planetary influence.
Charpak and Broch noted that "there is a difference of about twenty-two thousand miles between Earth's location on any specific date in two successive years" and that thus they should not be under the same influence according to astrology. Over a 40 years period there would be a difference greater than , miles. Edward W. James, commented that attaching significance to the constellation on the celestial sphere the sun is in at sunset was done on the basis of human factors—namely, that astrologers didn't want to wake up early, and the exact time of noon was hard to know.
Further, the creation of the zodiac and the disconnect from the constellations was because the sun is not in each constellation for the same amount of time. The tropical zodiac has no connection to the stars, and as long as no claims are made that the constellations themselves are in the associated sign , astrologers avoid the concept that precession seemingly moves the constellations because they don't reference them. Some astrologers make claims that the position of all the planets must be taken into account, but astrologers were unable to predict the existence of Neptune based on mistakes in horoscopes.
Instead Neptune was predicted using Newton's law of universal gravitation.

On the demotion of Pluto to the status of dwarf planet , Philip Zarka of the Paris Observatory in Meudon , France wondered how astrologers should respond: . Should astrologers remove it from the list of luminars [Sun, Moon and the 8 planets other than earth] and confess that it did not actually bring any improvement?
If they decide to keep it, what about the growing list of other recently discovered similar bodies Sedna, Quaoar. Astrology has been criticised for failing to provide a physical mechanism that links the movements of celestial bodies to their purported effects on human behaviour. In a lecture in , Stephen Hawking stated "The reason most scientists don't believe in astrology is because it is not consistent with our theories that have been tested by experiment. Bok , Lawrence E.
