The validity of astrology is controversial. A case for and a case against astrology's objective validity are presented here. Astrology refers to any of several systems, traditions or beliefs in which knowledge of the apparent positions of celestial bodies is held to be useful in understanding, interpreting, and organizing knowledge about human affairs and events on earth. ... In philosophy, objectivity is generally considered as the compatibility of propositions distinct and independent of propositional acts or attitudes. ...

Astrologers argue that no scientifically defined causal mechanism is required for astrology to be a valid and useful system of practical knowledge. Astrologers study the patterns of celestial bodies compared to earthly events and use their recorded knowledge to alert people to opportunities in life that might otherwise be missed or to warn about potentially destructive choices.

Skeptics and scientists say astrology fails to demonstrate its effectiveness in controlled studies, and see those who continue to use it as gullible and deluded, or even charlatans. Professionals who practice astrology maintain that skeptics' claims are based on a prejudice against astrological principles and that the skeptics themselves are not qualified to make any claims about the validity of astrology, a position generally known as non-falsifiability. Falsifiability is an important concept in the philosophy of science that amounts to the principle that a proposition or theory cannot be considered scientific if it does not admit the possibility of being shown false. ...

How astrologers view astrology

Professional astrologers, like many other professionals, are consultants with clients. Some are commentators on many aspects of life. In general, astrologers do not engage in investigative science and do not believe in reducing astrology to simple verifiable processes. Astrologers do not purport to predict the future with certainty, but rather are applying known practices of astrology, according to published literature concerning the craft. Astrology refers to any of several systems, traditions or beliefs in which knowledge of the apparent positions of celestial bodies is held to be useful in understanding, interpreting, and organizing knowledge about human affairs and events on earth. ...

Most astrologers consider astrology to be a useful intuitive tool by which people can come to better understand themselves, others, and the relationships between them. This may allow the opportunity to understand feelings and patterns of behavior that may affect one's future, and subsequently change one's actions in the present to bring about a desired future. Astrology conscientiously seeks to fulfill these human needs and this effort gives astrology a social and psychological validity. Intuition has many but close meanings across many cultures, including: Quick and ready insight seemingly independent of previous experiences and empirical knowledge Immediate apprehension or cognition Knowledge or conviction gained immediately and without detailed consideration The power or faculty of attaining knowledge or cognition immediately without thought and inference. ... A pattern is a form, template, or model (or, more abstractly, a set of rules) which can be used to make or to generate things or parts of a thing, especially if the things that are generated have enough in common for the underlying pattern to be inferred or discerned...

Astrology's continued appeal may rest on its ability to link an individual's life to the wider cosmos, and so give a feeling of uniqueness, meaning, and connection to the totality of things. Astrology also contains archetypal symbolism, which according to some schools of thought, such as Jungian psychology, can be found universally throughout humanity. This widespread, enduring, and universal quality lends astrology further validity. This article belongs in one or more categories. ... An archetype is an idealized model of a person, object, or concept from which similar instances are derived, copied, patterned, or emulated. ... Jungian psychology is a theory developed by Carl Gustav Jung, and is central to the Neopsychoanalytic school of psychology. ...

Although some astrologers may be interested in a more investigative or experimental approach to astrology, whereby astrology would advance by conjecture and falsifiable hypotheses, on the whole, astrologers do not regard this method as necessary or even desirable. Astrology reached a high level of development through its practical research long before the emergence of modern experimental science in the 16th century. Astrology has the aim of wellbeing and the improvement of life. It relies heavily on sharing observations, case studies, and the resolution of critical discussions to sustain itself as an evolving system of useful knowledge. In the scientific method, an experiment (Latin: ex-+-periri, of (or from) trying), is a set of actions and observations, performed in the context of solving a particular problem or question, to support or falsify a hypothesis or research concerning phenomena. ... In mathematics, a conjecture is a mathematical statement which has been proposed as a true statement, but which no one has yet been able to prove or disprove. ...

Validity and reputation

During its history, astrology has had periods of serious discussion and strong development and was studied in universities in the 14th and 15th centuries. During other periods, astrology flourished in much simplified versions, such as the period of the first mass-published almanacs and prognostications that came with the introduction of the printing press, or the sun-sign astrology newspaper columns that began to proliferate at the turn of the 20th century. During these periods astrology did not rise above simplistic forms. Following these upsurges of mass popularity and diminishing serious study, astrology tended to fall into disrepute and was driven underground by critics and skeptics, who used the reputation of astrology to attack its validity. During these darker periods, until its rediscovery, astrology tended to lose some of its basic integrity and become more secretive, esoteric, spritual, and obscure.

Many astrologers today scorn sun-sign horoscope predictions, in which people are labeled on the basis of their sun sign alone, as being exploitative and nothing more than entertainment for readers and a means to sell newspapers. The sun sign is regarded as only one of many factors that must be taken into account in astrological interpretation.

Astrologers who don't support the emphasis on sun signs want to push back both the skeptics and the sun-sign horoscope writers in order to expand the environment of sharing and critical involvement among colleagues that is required to advance astrology.

The complexity of astrology

Astrologers reject claims by skeptics that astrology is scientifically invalid or defined as a pseudoscience. It was astrologers who invented such mathematics used in modern science as algebra, geometry, trigonometry, logarithms, and astronomy itself. In a real sense, these mathematical inventions are the by-products of the practical effort to understand the complexities of astrology and improve its interpretation.

Twin studies example

Astrologers say a major problem of astrological validity is that astrology is so complex that it is often underestimated by skeptics who have not studied it and yet attempt to criticise it or test it. For example, it is reasoned by some skeptics that twins, because they have nearly similar natal charts, should have nearly similar personalities and lives, but in fact some twins are dramatically different. Astrologers have pointed out that the fallacy in this thinking is that similarity between people's charts does not mean that the astrological content of the charts can be ignored, because the content can account for similarities and differences.

According to the practice of astrology, twins whose natal charts indicate a tendency for close relationships are more likely to be conformist in their behavior, whereas twins whose charts strongly indicate competitive tendencies are more likely to exaggerate their differences and behave independently. Moreover, one twin with a sensitively placed planet, such as a planet within two degrees of either the child's own, or a parent's, horizon or meridian, can be perceived by the parents as having special needs.

The irrelevance of natural forces in astrology

Modern science has great power and allure, and this has led to more than a few proponents of "scientific astrology" to argue that the planets might influence people through such known forces as gravity or magnetic fields, or even through some as-yet unknown force.

Cialdini, Professor of Psychology at Arizona State University. ... Gravity is a force of attraction that acts between bodies that have mass. ...

• In a controlled experiment, biologist Dr. Frank Brown transported oysters from New Haven, Connecticut to Evanston, Illinois. At first the oysters responded as expected, opening and closing their shells in accord with the tide in New Haven. However, within a week, they began to get out of sync. Within two weeks, they had once again settled on a single rhythm, opening and closing in correlation with the tidal forces of Evanston, despite the fact that there was no physical motion of water to prompt their action. Apparently, some mechanism in the oyster was detecting the tidal force.
• Dr. Percy Seymour, an astronomer/astrophysicist at Plymouth University, UK, has argued that electromagnetic changes induced by the tidal forces of the planetary system could be responsible for astrology.

Although the concept of an astrology that is explained by natural forces has appeal, it conflicts with the long-standing practice in astrology of interpreting astrological charts not only for people, but for inanimate things (such as ships), and even intangible concepts or events (such as eureka moments or the birth of nations). If the charts of such inanimate things and intangible events are accepted by astrologers, which they universally are, then there is no necessary biological "organ of receptivity" for natural forces that can be causaly linked to the planets. Thus the force argument, despite the good intentions of Seymour and others like him, is seen by astrologers as specious. In the scientific method, an experiment (Latin: ex-+-periri, of (or from) trying), is a set of actions and observations, performed in the context of solving a particular problem or question, to support or falsify a hypothesis or research concerning phenomena. ...

Planetary distance example

In a similar vein, critics have argued that astrology does not account for the different distances to the planets, which should impact the strength of their effect. Critical astrologers have pointed out that this argument would be more rational if the planets all had the same properties and type of influence, except the planets have different astrological properties, which, in this line of reasoning, could account for the distance factor. However, this and many similar arguments are seen by astrologers as specious, because they too incorrectly assume that the action of interplanetary forces is the putative cause of astrology. Astrology does not rely upon the Cartesian concept of a push-pull mechanism as a causal explanation because astrology was developed long before the modern paradigms of mechanisms and forces were formalized by Descartes and Newton.

The misaligned zodiac

Another common argument by astrology critics is that the tropical zodiac used in Western astrology does not align with the starry constellations that have the same names, the implication being that because the names are the same there should be an equivalence between the tropical zodiac and these particular constellations. Although this is not a scientific argument, and the idea has no place in the professional practice of astrology, it has proved to be incredibly specious not only among astrology skeptics but also among popularizers of astrology. Some of these astrology writers have tried to match up the two systems and determine the beginning of the Age of Aquarius, which is when the vernal point (the starting point of the tropical zodiac) would be presumed to enter the constellation of Aquarius. These predictions vary within hundreds of years. The tropical zodiac is a zodiac based upon tropical time, or the apparent motion of the Sun across the sky over the course of a year. ...

Aquarius (Latin for the Water-bearer or Cup-bearer, symbol , Unicode â™’) is the eleventh sign of the zodiac, situated between Capricornus and Pisces. ...

Critical astrologers have pointed out that the problem with the theory of the misaligned zodiac is that Western astrology uses only symmetrical frames of reference that are based on natural features such as the horizon and meridian, the equinoxes and solstices, and the aspect phases between the planets. In practice, astrology does use some of the brighter stars, but only individually and not as constellations. The starry constellations, which are used to this day in modern astronomy, are neither natural nor symmetrical, but are purely imaginative designs that could just as easily have been very different. Thus it is irrational to believe or infer that something that is natural and symmetrical (the tropical zodiac used in astrology) should be equivalent to something that has no symmetrical properties and is purely imaginary (the starry constellations used in astronomy). Western astrology is the system of astrology most popular in Western countries. ...

Tropical zodiac example

Although some Western astrologers, most notably the mid-twentieth century Irish astrologer Cyril Fagan, have tried to develop a sidereal astrology that would reconcile Western astrology with Eastern astrologies that use a sidereal zodiac, the overwhelming majority of Western astrologers use the tropical zodiac. They point to the almost universal alignment of ancient monumental instruments of celestial mechanics to the equinox and solstice points as evidence that the earliest astrologers employed the natural symmetries of the tropical system. The movement of the Sun with respect to these points has an obvious association with the seasons, and the planets all travel approximately along the same seasonal path as the Sun, except at different rates and thus have their own seasonal patterns. Sidereal astrology is the practice by some western and all Indian astrologers of basing their study of the sky on the actual position of the planets in relation to the starry background. ...

The instruments of observation used by ancient astronomers/astrologers became larger and more precise for at least two reasons. Firstly, it was very difficult to determine the regular pattern of movement of the planet Mercury, which never travels very far from the Sun. Secondly, the ancient astonomers/astrologers were much interested in determining the angular distance from the Sun where a planet would appear to slow to a stop and change the direction of its motion. Sidereal systems did not provide the precision or the context necessary to resolve these problems.

How skeptics view astrology

Skeptics say astrology is a pseudoscience, which attempts to lay claim to the prestige of science without submitting itself to the discipline of scientific method. Skeptics consider astrology to lack falsifiability. That is, it is not possible to construct a test for astrology that it could demonstrably fail. Phrenology is regarded today as being a classic example of pseudoscience. ... Wikimedia Commons has media related to: Science For the scientific journal named Science, see Science (journal). ...

Falsifiability is an important concept in the philosophy of science that amounts to the principle that a proposition or theory cannot be considered scientific if it does not admit the possibility of being shown false. ...

Given that most astrologers claim to make predictions about future events, it should be possible to construct an experiment that at least measures its accuracy. No such experiment has ever demonstrated the objective validity of astrology. In addition, scientific double blind tests (example) have shown that even the best astrologers fare no better than random chance when matching astrological charts to personalities. In the scientific method, an experiment (Latin: ex-+-periri, of (or from) trying), is a set of actions and observations, performed in the context of solving a particular problem or question, to support or falsify a hypothesis or research concerning phenomena. ... In philosophy, objectivity is generally considered as the compatibility of propositions distinct and independent of propositional acts or attitudes. ... Double-blind describes an especially stringent way of conducting an experiment, usually on human subjects, in attempt to eliminate subjective bias on the part of both experimental subjects and the experimenters. ...

Astrology critics point out that its proponents respond to such lack of evidence, either by changing their claims, or by refusing to accept the scientific method as a valid test of their claims and relying instead on subjective and anecdotal evidence. If the scientific method is rejected then astrology must abandon all claim to being a science. By declining to attempt any experiments that might show astrology to be false, astrologers show themselves not to be scientists but rather holders of a faith or doctrine. Scientific method as envisaged by one of its early exponents, Sir Isaac Newton, is fundamental to the investigation and acquisition of new knowledge based upon physical evidence. ...

The established scientific view is that astrology is either mere superstition or imposture, and that its popularity is due either to New Age magical thinking, wilful deception or to unscientific gullibility on the part of the uneducated.

Arguments for astrology

Although ideas of gravitation, tidal forces, or magnetic influences as causal mechanisms that could explain astrology had gained some interest among proponents of astrology in the late 20th century, these ideas have been consistently dismissed by astrologers themselves as irrelevant. While these concepts of causal mechanisms have widespread application in modern science, they do not mesh well with astrological principles and the way in which astrology developed. In physics, gravitation or gravity is the the tendency of objects with mass to accelerate toward each other. ... This article is about tides in the ocean. ... In physics, magnetism is a phenomenon by which materials exert an attractive or repulsive force on other materials. ... A causal system is a system that depends only on the current and previous inputs. ...

A number of hypotheses have been put forward concerning the theoretical basis of astrology. These concepts do not depend on causal mechanisms and are considered to support the astrological tradition. A hypothesis (= assumption in ancient Greek) is a proposed explanation for a phenomenon. ... In mathematics, theory is used informally to refer to a body of knowledge about mathematics. ...

Fractal cosmology - The concept of fractals is widely used in modern-day science to describe natural phenomena. Theories of fractal cosmology have appeal to astrologers because they reflect the ancient hermetic axiom "as above, so below; as below, so above." The infinite repetitions of self-similar structures within fractal geometries at different microscopic and macroscopic scales suggests a cosmic symmetry between the microcosm of the individual and the macrocosm of the individual's planetary environment. Symmetries are part of the design economy of nature and astrologers consider from their observations that symmetry is applicable to astrology.

Chaos theory - Chaos theory, especially the concept of sensitive dependency on initial conditions, such as the idea that a butterfly flapping its wings in Brazil can lead to a tornado in Texas, has appeal to astrologers. The initial conditions of birth occur within a particular environment of planetary patterns. The continual movement of the planets with respect to this initial configuration is believed to mirror significant life events. Birth instead of conception is universally chosen in astrology because conception occurs at a microcosmic scale that is of little use or interest in astrology. Birth, the first intake of air, is the moment in life when a person enters into the world that we all know and participate in as individuals. Astrology places the birth of the individual at the center of the universe and the celestial bodies are all planets of the individual. By tracking celestial patterns and providing advice, astrologers endeavour to promote wellbeing and prevent the individual's circumstances at birth (likened to the gentle flap of the butterfly's wings) from eventually leading to a raging disaster.

Cosmic synchronicity - The vast majority of astrologers in the world today believe that astrology is a purely correlative study that reflects the underlying patterns in various systems, without any mechanism for a causal planetary influence at all. Proponents of this theory usually point to the work of the Swiss psycholgist Carl Jung, and his idea of synchronicity. In astrology, however, this synchronicity is believed to occur only between the individual and the interplanetary environment, and can be thought of as the time counterpart of the cosmic symmetry of space. Synchronicity is a word coined by the Swiss psychologist Carl Jung to describe the temporally coincident occurences of acausal events. Jung also spoke of synchronicity as being an acausal connecting principle (ie. ...

Cycle studies - Astrologers look to the movements of the planets as a way to compare, record, and measure of events on Earth because of the great regularity and predictable rhythms of the interplanetary environment. Researchers of cyclic phenomena have recorded hundreds of periodic rhythms, such as animal populations and commodity prices, but typically such cycles are simply periodic repetitions of the same thing. In astrology, planetary cycles are not repetitions of the same thing but are observed to be developmental patterns that resemble each other as they pass through predictable phases or stages within the signs, houses, and aspects. Modern practitioners of Western astrology maintain that the comparison of life patterns with predictable planetary cycles does not mean that astrological meanings are immutable, fatalistic, or determistic, and astrology does not seek the sort of hard definitions or constants that are used in science, particularly physics. As can be seen in any astrology text, astrological meanings tend to accumulate in fuzzy clusters, themes, or archetypes, which can be interpreted in somewhat differing though significantly related ways.

Gauquelin/Ertel experimental findings - In the 1950s and 60s, French psychologist Michel Gauquelin published his discoveries[2] of pronounced statistical correlations for several celestial bodies (Moon, Venus, Mars, Jupiter, and Saturn) that were in substantive agreement with the traditional astrological meanings of these planets, as described in any typical astrology textbook. Although the correlation of Mars (the easiest planet to test) with accurately timed birth charts of famous sports champions was subsequently replicated[3] by other researchers, who worked independently using their own collected birth data, the Mars finding was greatly substantiated by the investigation of German professor of psychology Suitbert Ertel, who published his findings in 1988. Ertel imposed strict scientific protocols for eminence (fame) as a method to rule out sampling bias as a reasonable contributor to the planetary correlations. Ertel's Mars test produced a striking functional relationship for eminence[4], which had been predicted earlier (although never before tested) by Gauquelin. Eminence was found to increase in proportion to the frequency of Mars in the specified zones (Mars rising and Mars culminating). Michel Gauquelin (November 13, 1928 - May 20, 1991) was a French psychologist and statistician who, along with his wife Francoise, conducted serious statistical research into astrology. ...

Environmental cosmology - Concepts of fractals and synchronicity have been further related to astrology by astrologer Ken McRitchie, who published his theories on environmental cosmology in 2004. McRitchie argues that the meanings of the astrological signs, houses, and aspects can be compared to similar models of personality and behavior that have been developed in the social sciences. Environmental cosmology is an attempt to develop a set principles and theories that support a modern-day view of Western astrology, as proposed by Ken McRitchie. ...

Arguments against astrology

There is no scientific case for astrology, and there are no credible scientists who support the idea. Here are some common arguments used by astrology skeptics.

No theoretical basis

Opponents complain that there is not theoretical basis for astrology and that all ideas proposed as yet do not stand scrutiny.

Gravitational forces aspect

There are various claims by astrologers that distant planets affect us through either gravitation, electromagnetism, or some other as yet undetected force. Scientists know of no force from distant stars or planets that is capable or affecting our lives and personalities here on earth. Consider the following scenarios: In physics, gravitation or gravity is the the tendency of objects with mass to accelerate toward each other. ... Electromagnetism is the physics of the electromagnetic field: a field, encompassing all of space, which exerts a force on those particles that possess the property of electric charge, and is in turn affected by the presence and motion of such particles. ... In physics, a force is defined as a rate of change of momentum (Newtonian definition). ...

• Astrologers sometimes claim to have scientific explanations for their practices. For example, it is pointed out that the moon causes tides on earth, and it is reasoned that the gravitational pull of other heavenly bodies affect us. This is flawed for the following reasons:
  1. The gravitational pull from e.g. Saturn, when calculated for its effect over an area the size of the human body, is equal to the gravitational pull from a car 1.7 meters away. Yet astrologers do not seem to be interested in the positions of cars at the time of birth, or indeed whether one was born in a car park. As a matter of fact, the gravitational pull of Earth itself varies more from place to place than the pull of even the largest planets.
  2. If direction and strength of the gravitational field is important, then surely nearby massive objects (cars, mountains, houses) and the birthing position would play a far greater role than distant planets. If electromagnetic fields and radiation play a role, then certainly the relatively weak (at least indoors) solar radiation and weak magnetic field of the earth would be drowned out by artificial lighting, TV screens, medical equipment or even refrigerator magnets.
  3. Astrology also does not offer any explanation of how this minuscule gravitational pull from other planets comes to affect personality, why we are especially susceptible to gravitation during birth nor how the gravitational influences at one point in the past affects our outlook for the future.

Magnetic influence

Another attempt at scientific explanation is that heavenly bodies affect the Earth's magnetic field, and that the magnetic field at the time of birth affects the person. To what extent this is true is largely irrelevant: The Earth's magnetic field is quite weak, and varies from 0.3 to 0.6 Gauss according to location. One would get a considerably stronger exposure to a magnetic field from an ordinary refrigerator magnet. It has been suggested that Magnetic field density be merged into this article or section. ...

The gauss, abbreviated as G, is the cgs unit of magnetic flux density or magnetic induction (B), named after the German mathematician and physicist Carl Friedrich Gauss. ...

Fractals and chaos theory

The use of fractals by astrologists is as analogy, not an as explanation. How chaos theory should make it possible for astrology to predict accurately is unclear.

Synchronicity

Astrologists mistake correlation for causation. In probability theory and statistics, correlation, also called correlation coefficient, is a numeric measure of the strength of linear relationship between two random variables. ... This article is about causality as it is used in many different fields. ...

The question of distance

Astrology does not address how distance to a stellar object affects its astrological impact. If distance is relevant, astrological charts do not take it into account.

Extra heavenly bodies

Astrological charts do not consider all stellar objects, including planets, moons, and distant stars, although some fixed stars are included in some astrological systems. A fixed star is a celestial object that does not seem to move (in comparison to the other stars of the night sky). ...

Modern solar system bodies discoveries

Adherents of astrology have claimed that its techniques have been accurate for many centuries. However, three planets (Uranus, Neptune and Pluto), were only discovered within the last 250 years. Many astrologers have now integrated these planets into their systems. If these planets (or any, for that matter) affected life on earth in an astrological sense, there should have been measurable discrepancies between reality and prediction before these planets were discovered.

Atmospheric characteristics Surface pressure ≫100 MPa Hydrogen - H2 80% ±3. ... Atmospheric characteristics Atmospheric pressure 0. ...

Inconsistency of effect

Astrology shows an inconsistency on its terms. Assuming a theoretical force emanated by any celestial body, it is unclear how such a force could influence so differently two people located on Earth only hundreds of miles apart. Only the angle of incidence is left as a parameter. If this force exists, it shows a very singular behavior, unique in the physical laws, yet to be observed.

Astrological and astronomical zodiac differences

• The zodiac system used by astrologers has never aligned with the constellations. The tropical zodiac and the sidereal zodiac both divide the ecliptic into 12 equal portions of 30 degrees, but the constellations of the zodiac all vary in size, from 44 degrees across for Virgo to 20 degrees across for Cancer.
• The tropical zodiac used by most western astrologers begins at the vernal point, which gradually changes its position due to the precession of Earth's axis, known as the precession of the equinoxes. Over the course of 2000 years, the tropical zodiac has shifted about 24 degrees, so any celestial object said to be in one astrological sign will, upon observation of the present night sky, usually be found occupying the next zodiacal constellation.
• The sidereal zodiac, used by many eastern astrologers, deducts about 24 degrees to account for the precession of the equinoxes, but it still does not align perfectly with the constellations because the constellations are of unequal sizes, rather than each being 30 degrees across, as the sidereal zodiac requires.
• Many who are skeptical using this claim continue to ignore that the only difference between tropical and sidereal zodiacs is due to the precession of the equinoxes. Each system - tropical and sidereal - is used as an astrological "technique" - and so the argument maintained by skeptics concerning the constellations and the seasons continues to be used to debunk astrology without admitting understanding of the tropical and sidereal systems and the techniques versus an actual philosophy concerning the "seasons" and the "constellations" themselves as seen from an earth-based vantage point.

The thirteenth zodiacal constellation

Many people note that there are 13 constellations of unequal size along the astronomical ecliptic, and not twelve equally-sized constellations, to try to discredit or otherwise disprove astrology. To astrologers, the size of the actual astronomical constellations is a not an issue because most Western astrologers use the tropical zodiac, where the ecliptic is divided into 12 equal portions exactly 30 degrees each to get the 12 astrological signs starting at the vernal equinox point where the ecliptic and the equator cross with the sun moving north. (12 signs x 30 degrees each sign = the 360 degrees of the ecliptic). The tropical zodiac is a zodiac based upon tropical time, or the apparent motion of the Sun across the sky over the course of a year. ...

Of the 13 modern signs of the zodiac (constellations of the ecliptic), Ophiuchus is the only one not counted as an astrological sign. Some astrologers argue that this is because the area of Ophiuchus intersected by the ecliptic previously belonged to more than one constellation. The constellations were redefined by the International Astronomical Union in 1930 and include a portion of Ophiuchus (Serpent-Bearer) on the ecliptic, to get 88 constellations. Prior to 1930 some areas of the sky did not belong to a constellation, forcing astronomers to refer to "the area between constellation X and constellation Y". Some areas, like the foot of Ophiuchus, belonged to more than one constellation. The modern constellation boundaries were defined to resolve this problem, so that every part of the sky belongs to one clearly defined constellation. However, Ptolemy recognised in ancient times that the sun passes through Opiuchus. Therefore, even by the ancient defintion, Opiuchus is a constellation of the zodiac, and the arguments about the IAU 20th century redefinition of the constellations are specious. According to this view, the use by modern astrologers of only 12 signs is erroneous. Some argue that the choice of 12 signs was driven more by numerological than astronomical considerations.

Arbitrary nature of modern and old zodiac mismatch

Critics of astrology say that astrologers who use the tropical zodiac, as almost all in the west do, take an arbitrary point 2000 years ago in the past as the basis for their interpretation of the heavens. The zodiac of 2000 years ago holds no special place in astronomy. If we go back 4000 years we find Taurus was the constellation of the Vernal equinox, if we go back 6000, we find Gemini. Critics of astrology say that astronomers understand that the view of the heavens continually changes over long periods of time, while most astrologers use a fixed and inaccurate version of reality. Critics also point out that most modern astrologers are unwilling to adapt to a modern astronomical model of the heavens.

Time of birth

• One supporter of astrology, Dr. Percy Seymour, has been criticized for ignoring the many surveys and experiments that show no connection between planetary positions at the time of birth, and focusing on the one that provides questionable data to support his idea, see the Mars effect. See the External links section below for articles discussing his books.
• No one has yet come up with a credible theory of why the time of birth is so crucial (and not, for instance, the moment of conception or some time during the pregnancy).
• Twins. By the logic of astrology, twins should almost always have nearly the same life outcomes. Although anecdotes are frequently told about separated twins who live coincidental lives, this is the exception and not the rule.
• Astrologers ask only the Date, Time and place of birth to form horoscope and predict about one's future. If the places of birth are few hundred kilometers away of each other, and the time is close enough, then two people's horoscopes should be the same. But this never means two people have the same future.
• Similarly, when thousands of people die simultaneously in a natural disaster or plane crash, it cannot be said that they had same horoscopes.

The Mars effect is a claim that Mars occupies certain positions in the sky more often at the birth of sports champions than at the birth of ordinary people. ... Fraternal twin boys in the tub The term twin most notably refers to two individuals (or one of two individuals) who have shared the same uterus (womb) and usually, but not necessarily, born on the same day. ...

Age among peer groups

Many Western societies use a child's age in September to determine the year in which he or she will begin formal education. Because of this, the average student born in September will spend his or her childhood and adolescence with peers who are mostly older, while a student born in August will spend this time with peers who are mostly younger. Therefore, even assuming that traditional justifications for astrology are entirely false, horoscope signs may still correlate with assertiveness but this may be an artifact of the educational system. Look up September in Wiktionary, the free dictionary. ... August is the eighth month of the year in the Gregorian Calendar and one of seven Gregorian months with the length of 31 days. ...

Unreliability

If astrology were as accurate as its proponents claim, it could arguably be used to allow people to avoid bad events happening in the future. But according to some astrologers, the future is unmalleable.

Paradox of immutability

Astrology does not claim immutability. Nonetheless a thought-provoking question can be raised: Future prediction necessarily implies a degree of immutability: it is the very reason which makes any prediction possible. But if the future is immutable, there is no point in knowing what can not be changed. This article or section does not cite its references or sources. ...

Empirical tests

Scientific tests on astrology have been performed and proved it to be inaccurate.

Failed predictions

For example, a gathering of international astrologers just before the Indian parliament elections unanimously predicted that the Bharatiya Janata Party would come to power, and that Atal Bihari Bajpai would be next Prime Minister of India, and that Mrs Sonia Gandhi and Rahul Gandhi had no political future. They were all proved wrong as the BJP did not win the election and Sonia Gandhi has been named one of the most powerful women in the world.

Hemisphere Differences

Tropical astrology overlooks the absurdity of using a zodiac based on the seasons in the northern hemisphere when there are today large populations in the southern hemisphere who experience the seasons 6 months apart from those in the north. If symmetry were the basis for astrology then a different set of signs with a 6 months difference, and Aries commencing on 21st September, would be appropriate for them.

Possible explanations why people believe in astrology

Skeptics have found some effects that may explain why astrology is popular despite its shortcomings.

Forer effect

One scientific explanation for the widespread belief in astrology is the so-called Forer effect (also called personal validation fallacy or the Barnum effect after P.T. Barnum). In 1948, Forer observed that individuals will give high accuracy ratings to descriptions of their personality that supposedly are tailored specifically for them, which are in fact vague and general enough to apply to a wide range of people.

Psychological points

In The Stars Down To Earth, Theodor Adorno of the Frankfurt School, continued his consideration of the role of the culture industry by examining the astrological columns of the daily papers in 1951. He accused them of false consciousness, demonstrating how the columns encouraged the low-level clerical or office workers to identify with the social rungs above them. But "false" consciousness is by definition multiple consciousness and ambivalence, and narrative and psychological theory allow consciousness to follow its own dialectical laws in which the astrological reader engages in a quite respectable suspension of disbelief (cf. the psychology of the lottery ticket buyer, who probably knows how slim the chances are) and never decouples from the judgment that a world is possible in which people, albeit half ironically, peruse the "stars" for clues. Max Horkheimer (front left), Theodor Adorno (front right), and Jürgen Habermas in the background, right, in 1965 at Heidelberg Theodor Ludwig Wiesengrund Adorno (September 11, 1903 – August 6, 1969) was a German sociologist, philosopher, musicologist and composer. ...

Relationship to various sciences

The distinction between astrology and astronomy was not made until relatively recently (see History of astrology and History of astronomy). Today, astrology is viewed as astronomy's predecessor in the same way that alchemy is viewed as the predecessor of chemistry. While scientists dismiss modern astrology as a pseudoscience, they will admit to its historical status as a proto-science.
