Astrology is a pseudoscience that claims to divine information about human affairs and terrestrial events by studying the movements and relative positions of celestial objects. Astrology has been dated to at least the 2nd millennium BCE, and has its roots in calendrical systems used to predict seasonal shifts and to interpret celestial cycles as signs of divine communications. Many cultures have attached importance to astronomical events, and some—such as the Hindus, Chinese, and the Maya—developed elaborate systems for predicting terrestrial events from celestial observations. Western astrology, one of the oldest astrological systems still in use, can trace its roots to 19th–17th century BCE Mesopotamia, from where it spread to Ancient Greece, Rome, the Arab world and eventually Central and Western Europe. Contemporary Western astrology is often associated with systems of horoscopes that purport to explain aspects of a person's personality and predict significant events in their lives based on the positions of celestial objects; the majority of professional astrologers rely on such systems.:83

Throughout most of its history, astrology was considered a scholarly tradition and was common in academic circles, often in close relation with astronomy, alchemy, meteorology, and medicine. It was present in political circles and is mentioned in various works of literature, from Dante Alighieri and Geoffrey Chaucer to William Shakespeare, Lope de Vega, and Calderón de la Barca. Following the end of the 19th century and the wide-scale adoption of the scientific method, researchers have successfully challenged astrology on both theoretical:249; and experimental grounds, and have shown it to have no scientific validity or explanatory power. Astrology thus lost its academic and theoretical standing, and common belief in it has largely declined. While polls have demonstrated that approximately one quarter of American, British, and Canadian people say they continue to believe that star- and planet-positions affect their lives, astrology is now recognized as a pseudoscience — a belief which its advocates incorrectly present as scientific.
The word astrology comes from the early Latin word astrologia, which derives from the Greek ἀστρολογία—from ἄστρον astron ("star") and -λογία -logia, ("study of"—"account of the stars"). Astrologia later passed into meaning 'star-divination' with astronomia used for the scientific term.
Many cultures have attached importance to astronomical events, and the Indians, Chinese, and Maya developed elaborate systems for predicting terrestrial events from celestial observations. In the West, astrology most often consists of a system of horoscopes purporting to explain aspects of a person's personality and predict future events in their life based on the positions of the sun, moon, and other celestial objects at the time of their birth. The majority of professional astrologers rely on such systems.:83
Astrology has been dated to at least the 2nd millennium BCE, with roots in calendrical systems used to predict seasonal shifts and to interpret celestial cycles as signs of divine communications. A form of astrology was practised in the first dynasty of Mesopotamia (1950–1651 BCE). Vedāṅga Jyotiṣa is one of earliest known Hindu texts on astronomy and astrology (Jyotisha). The text is dated between 1400 BCE to final centuries BCE by various scholars according to astronomical and linguistic evidences. Chinese astrology was elaborated in the Zhou dynasty (1046–256 BCE). Hellenistic astrology after 332 BCE mixed Babylonian astrology with Egyptian Decanic astrology in Alexandria, creating horoscopic astrology. Alexander the Great's conquest of Asia allowed astrology to spread to Ancient Greece and Rome. In Rome, astrology was associated with 'Chaldean wisdom'. After the conquest of Alexandria in the 7th century, astrology was taken up by Islamic scholars, and Hellenistic texts were translated into Arabic and Persian. In the 12th century, Arabic texts were imported to Europe and translated into Latin. Major astronomers including Tycho Brahe, Johannes Kepler and Galileo practised as court astrologers. Astrological references appear in literature in the works of poets such as Dante Alighieri and Geoffrey Chaucer, and of playwrights such as Christopher Marlowe and William Shakespeare.
Throughout most of its history, astrology was considered a scholarly tradition. It was accepted in political and academic contexts, and was connected with other studies, such as astronomy, alchemy, meteorology, and medicine. At the end of the 17th century, new scientific concepts in astronomy and physics (such as heliocentrism and Newtonian mechanics) called astrology into question. Astrology thus lost its academic and theoretical standing, and common belief in astrology has largely declined.
Astrology, in its broadest sense, is the search for meaning in the sky.:2,3 Early evidence for humans making conscious attempts to measure, record, and predict seasonal changes by reference to astronomical cycles, appears as markings on bones and cave walls, which show that lunar cycles were being noted as early as 25,000 years ago.:81ff This was a first step towards recording the Moon's influence upon tides and rivers, and towards organising a communal calendar. Farmers addressed agricultural needs with increasing knowledge of the constellations that appear in the different seasons—and used the rising of particular star-groups to herald annual floods or seasonal activities. By the 3rd millennium BCE, civilisations had sophisticated awareness of celestial cycles, and may have oriented temples in alignment with heliacal risings of the stars.
Scattered evidence suggests that the oldest known astrological references are copies of texts made in the ancient world. The Venus tablet of Ammisaduqa is thought to be compiled in Babylon around 1700 BCE. A scroll documenting an early use of electional astrology is doubtfully ascribed to the reign of the Sumerian ruler Gudea of Lagash (c. 2144 – 2124 BCE). This describes how the gods revealed to him in a dream the constellations that would be most favourable for the planned construction of a temple. However, there is controversy about whether these were genuinely recorded at the time or merely ascribed to ancient rulers by posterity. The oldest undisputed evidence of the use of astrology as an integrated system of knowledge is therefore attributed to the records of the first dynasty of Mesopotamia (1950–1651 BCE). This astrology had some parallels with Hellenistic Greek (western) astrology, including the zodiac, a norming point near 9 degrees in Aries, the trine aspect, planetary exaltations, and the dodekatemoria (the twelve divisions of 30 degrees each). The Babylonians viewed celestial events as possible signs rather than as causes of physical events.
The system of Chinese astrology was elaborated during the Zhou dynasty (1046–256 BCE) and flourished during the Han Dynasty (2nd century BCE to 2nd century CE), during which all the familiar elements of traditional Chinese culture – the Yin-Yang philosophy, theory of the five elements, Heaven and Earth, Confucian morality – were brought together to formalise the philosophical principles of Chinese medicine and divination, astrology and alchemy.:3,4
The Hellenistic schools of philosophical skepticism criticized the rationality of astrology. Criticisms of astrology by Academic Skeptics such as Cicero, Carneades, and Favorinus; and Pyrrhonists such as Sextus Empiricus have been preserved.
Carneades argued that belief in fate denies free will and morality; that people born at different times can all die in the same accident or battle; and that contrary to uniform influences from the stars, tribes and cultures are all different.
Cicero stated the twins objection (that with close birth times, personal outcomes can be very different), later developed by Saint Augustine. He argued that since the other planets are much more distant from the earth than the moon, they could have only very tiny influence compared to the moon's. He also argued that if astrology explains everything about a person's fate, then it wrongly ignores the visible effect of inherited ability and parenting, changes in health worked by medicine, or the effects of the weather on people.
Favorinus argued that it was absurd to imagine that stars and planets would affect human bodies in the same way as they affect the tides, and equally absurd that small motions in the heavens cause large changes in people's fates.
The Neoplatonist Plotinus argued that since the fixed stars are much more distant than the planets, it is laughable to imagine the planets' effect on human affairs should depend on their position with respect to the zodiac. He also argues that the interpretation of the moon's conjunction with a planet as good when the moon is full, but bad when the moon is waning, is clearly wrong, as from the moon's point of view, half of its surface is always in sunlight; and from the planet's point of view, waning should be better, as then the planet sees some light from the moon, but when the moon is full to us, it is dark, and therefore bad, on the side facing the planet in question.
With the occupation by Alexander the Great in 332 BCE, Egypt became Hellenistic. The city of Alexandria was founded by Alexander after the conquest, becoming the place where Babylonian astrology was mixed with Egyptian Decanic astrology to create Horoscopic astrology. This contained the Babylonian zodiac with its system of planetary exaltations, the triplicities of the signs and the importance of eclipses. It used the Egyptian concept of dividing the zodiac into thirty-six decans of ten degrees each, with an emphasis on the rising decan, and the Greek system of planetary Gods, sign rulership and four elements. 2nd century BCE texts predict positions of planets in zodiac signs at the time of the rising of certain decans, particularly Sothis. The astrologer and astronomer Ptolemy lived in Alexandria. Ptolemy's work the Tetrabiblos formed the basis of Western astrology, and, "...enjoyed almost the authority of a Bible among the astrological writers of a thousand years or more."
Greece and Rome
The conquest of Asia by Alexander the Great exposed the Greeks to ideas from Syria, Babylon, Persia and central Asia. Around 280 BCE, Berossus, a priest of Bel from Babylon, moved to the Greek island of Kos, teaching astrology and Babylonian culture. By the 1st century BCE, there were two varieties of astrology, one using horoscopes to describe the past, present and future; the other, theurgic, emphasising the soul's ascent to the stars. Greek influence played a crucial role in the transmission of astrological theory to Rome.
The first definite reference to astrology in Rome comes from the orator Cato, who in 160 BCE warned farm overseers against consulting with Chaldeans, who were described as Babylonian 'star-gazers'. Among both Greeks and Romans, Babylonia (also known as Chaldea) became so identified with astrology that 'Chaldean wisdom' became synonymous with divination using planets and stars. The 2nd-century Roman poet and satirist Juvenal complains about the pervasive influence of Chaldeans, saying, "Still more trusted are the Chaldaeans; every word uttered by the astrologer they will believe has come from Hammon's fountain."
One of the first astrologers to bring Hermetic astrology to Rome was Thrasyllus, astrologer to the emperor Tiberius, the first emperor to have had a court astrologer, though his predecessor Augustus had used astrology to help legitimise his Imperial rights.
The main texts upon which classical Indian astrology is based are early medieval compilations, notably the Bṛhat Parāśara Horāśāstra, and Sārāvalī by Kalyāṇavarma. The Horāshastra is a composite work of 71 chapters, of which the first part (chapters 1–51) dates to the 7th to early 8th centuries and the second part (chapters 52–71) to the later 8th century. The Sārāvalī likewise dates to around 800 CE. English translations of these texts were published by N.N. Krishna Rau and V.B. Choudhari in 1963 and 1961, respectively.
Astrology was taken up by Islamic scholars following the collapse of Alexandria to the Arabs in the 7th century, and the founding of the Abbasid empire in the 8th. The second Abbasid caliph, Al Mansur (754–775) founded the city of Baghdad to act as a centre of learning, and included in its design a library-translation centre known as Bayt al-Hikma 'House of Wisdom', which continued to receive development from his heirs and was to provide a major impetus for Arabic-Persian translations of Hellenistic astrological texts. The early translators included Mashallah, who helped to elect the time for the foundation of Baghdad, and Sahl ibn Bishr, (a.k.a. Zael), whose texts were directly influential upon later European astrologers such as Guido Bonatti in the 13th century, and William Lilly in the 17th century. Knowledge of Arabic texts started to become imported into Europe during the Latin translations of the 12th century.
The first astrological book published in Europe was the Liber Planetis et Mundi Climatibus ("Book of the Planets and Regions of the World"), which appeared between 1010 and 1027 AD, and may have been authored by Gerbert of Aurillac. Ptolemy's second century AD Tetrabiblos was translated into Latin by Plato of Tivoli in 1138. The Dominican theologian Thomas Aquinas followed Aristotle in proposing that the stars ruled the imperfect 'sublunary' body, while attempting to reconcile astrology with Christianity by stating that God ruled the soul. The thirteenth century mathematician Campanus of Novara is said to have devised a system of astrological houses that divides the prime vertical into 'houses' of equal 30° arcs, though the system was used earlier in the East. The thirteenth century astronomer Guido Bonatti wrote a textbook, the Liber Astronomicus, a copy of which King Henry VII of England owned at the end of the fifteenth century.
In Paradiso, the final part of the Divine Comedy, the Italian poet Dante Alighieri referred "in countless details" to the astrological planets, though he adapted traditional astrology to suit his Christian viewpoint, for example using astrological thinking in his prophecies of the reform of Christendom.
In the seventh century, Isidore of Seville argued in his Etymologiae that astronomy described the movements of the heavens, while astrology had two parts: one was scientific, describing the movements of the sun, the moon and the stars, while the other, making predictions, was theologically erroneous. In contrast, John Gower in the fourteenth century defined astrology as essentially limited to the making of predictions. The influence of the stars was in turn divided into natural astrology, with for example effects on tides and the growth of plants, and judicial astrology, with supposedly predictable effects on people. The fourteenth century sceptic Nicole Oresme however included astronomy as a part of astrology in his Livre de divinacions. Oresme argued that current approaches to prediction of events such as plagues, wars, and weather were inappropriate, but that such prediction was a valid field of inquiry. However, he attacked the use of astrology to choose the timing of actions (so-called interrogation and election) as wholly false, and rejected the determination of human action by the stars on grounds of free will. The friar Laurens Pignon (c. 1368–1449) similarly rejected all forms of divination and determinism, including by the stars, in his 1411 Contre les Devineurs. This was in opposition to the tradition carried by the Arab astronomer Albumasar (787-886) whose Introductorium in Astronomiam and De Magnis Coniunctionibus argued the view that both individual actions and larger scale history are determined by the stars.
In the late 1400s, Giovanni Pico della Mirandola forcefully attacked astrology in Disputationes contra Astrologos, arguing that the heavens neither caused, nor heralded earthly events. His contemporary, Pietro Pomponazzi, a "rationalistic and critical thinker" was much more sanguine about astrology and critical of Pico's attack.
Renaissance and Early Modern
Renaissance scholars commonly practised astrology. Gerolamo Cardano cast the horoscope of king Edward VI of England, while John Dee was the personal astrologer to queen Elizabeth I of England. Catherine de Medici paid Michael Nostradamus in 1566 to verify the prediction of the death of her husband, king Henry II of France made by her astrologer Lucus Gauricus. Major astronomers who practised as court astrologers included Tycho Brahe in the royal court of Denmark, Johannes Kepler to the Habsburgs, Galileo Galilei to the Medici, and Giordano Bruno who was burnt at the stake for heresy in Rome in 1600. The distinction between astrology and astronomy was not entirely clear. Advances in astronomy were often motivated by the desire to improve the accuracy of astrology.
Ephemerides with complex astrological calculations, and almanacs interpreting celestial events for use in medicine and for choosing times to plant crops, were popular in Elizabethan England. In 1597, the English mathematician and physician Thomas Hood made a set of paper instruments that used revolving overlays to help students work out relationships between fixed stars or constellations, the midheaven, and the twelve astrological houses. Hood's instruments also illustrated, for pedagogical purposes, the supposed relationships between the signs of the zodiac, the planets, and the parts of the human body adherents believed were governed by the planets and signs. While Hood's presentation was innovative, his astrological information was largely standard and was taken from Gerard Mercator's astrological disc made in 1551, or a source used by Mercator.
English astrology had reached its zenith by the 17th century. Astrologers were theorists, researchers, and social engineers, as well as providing individual advice to everyone from monarchs downwards. Among other things, astrologers claimed to be able to advise on the best time to take a journey or harvest a crop, diagnose and prescribe for physical or mental illnesses, and predict natural disasters. This underpinned a system in which everything – people, the world, the universe – was understood to be interconnected, and astrology co-existed happily with religion, magic and science.
Enlightenment period and onwards
During the Enlightenment, intellectual sympathy for astrology fell away, leaving only a popular following supported by cheap almanacs. One English almanac compiler, Richard Saunders, followed the spirit of the age by printing a derisive Discourse on the Invalidity of Astrology, while in France Pierre Bayle's Dictionnaire of 1697 stated that the subject was puerile. The Anglo-Irish satirist Jonathan Swift ridiculed the Whig political astrologer John Partridge.
Astrology saw a popular revival starting in the 19th century, as part of a general revival of spiritualism and—later, New Age philosophy,:239–249 and through the influence of mass media such as newspaper horoscopes.:259–263 Early in the 20th century the psychiatrist Carl Jung developed some concepts concerning astrology, which led to the development of psychological astrology.:251–256;
Principles and practice
Advocates have defined astrology as a symbolic language, an art form, a science, and a method of divination. Though most cultural astrology systems share common roots in ancient philosophies that influenced each other, many use methods that differ from those in the West. These include Hindu astrology (also known as "Indian astrology" and in modern times referred to as "Vedic astrology") and Chinese astrology, both of which have influenced the world's cultural history.
Western astrology is a form of divination based on the construction of a horoscope for an exact moment, such as a person's birth. It uses the tropical zodiac, which is aligned to the equinoctial points.
Western astrology is founded on the movements and relative positions of celestial bodies such as the Sun, Moon and planets, which are analysed by their movement through signs of the zodiac (twelve spatial divisions of the ecliptic) and by their aspects (based on geometric angles) relative to one another. They are also considered by their placement in houses (twelve spatial divisions of the sky). Astrology's modern representation in western popular media is usually reduced to sun sign astrology, which considers only the zodiac sign of the Sun at an individual's date of birth, and represents only 1/12 of the total chart.
The horoscope visually expresses the set of relationships for the time and place of the chosen event. These relationships are between the seven 'planets', signifying tendencies such as war and love; the twelve signs of the zodiac; and the twelve houses. Each planet is in a particular sign and a particular house at the chosen time, when observed from the chosen place, creating two kinds of relationship. A third kind is the aspect of each planet to every other planet, where for example two planets 120° apart (in 'trine') are in a harmonious relationship, but two planets 90° apart ('square') are in a conflicted relationship. Together these relationships and their interpretations supposedly form "...the language of the heavens speaking to learned men."
Along with tarot divination, astrology is one of the core studies of Western esotericism, and as such has influenced systems of magical belief not only among Western esotericists and Hermeticists, but also belief systems such as Wicca that have borrowed from or been influenced by the Western esoteric tradition. Tanya Luhrmann has said that "all magicians know something about astrology," and refers to a table of correspondences in Starhawk's The Spiral Dance, organised by planet, as an example of the astrological lore studied by magicians.
Hindu natal astrology originated with Hellenistic astrology by the 3rd century BCE,:361 though incorporating the Hindu lunar mansions. The names of the signs (e.g. Greek 'Krios' for Aries, Hindi 'Kriya'), the planets (e.g. Greek 'Helios' for Sun, astrological Hindi 'Heli'), and astrological terms (e.g. Greek 'apoklima' and 'sunaphe' for declination and planetary conjunction, Hindi 'apoklima' and 'sunapha' respectively) in Varaha Mihira's texts are considered conclusive evidence of a Greek origin for Hindu astrology. The Indian techniques may also have been augmented with some of the Babylonian techniques.:231
Chinese and East Asian
Chinese astrology has a close relation with Chinese philosophy (theory of the three harmonies: heaven, earth and man) and uses concepts such as yin and yang, the Five phases, the 10 Celestial stems, the 12 Earthly Branches, and shichen (時辰 a form of timekeeping used for religious purposes). The early use of Chinese astrology was mainly confined to political astrology, the observation of unusual phenomena, identification of portents and the selection of auspicious days for events and decisions.:22,85,176
The constellations of the Zodiac of western Asia and Europe were not used; instead the sky is divided into Three Enclosures (三垣 sān yuán), and Twenty-Eight Mansions (二十八宿 èrshíbā xiù) in twelve Ci (十二次). The Chinese zodiac of twelve animal signs is said to represent twelve different types of personality. It is based on cycles of years, lunar months, and two-hour periods of the day (the shichen). The zodiac traditionally begins with the sign of the Rat, and the cycle proceeds through 11 other animals signs: the Ox, Tiger, Rabbit, Dragon, Snake, Horse, Goat, Monkey, Rooster, Dog, and Pig. Complex systems of predicting fate and destiny based on one's birthday, birth season, and birth hours, such as ziping and Zi Wei Dou Shu (simplified Chinese: 紫微斗数; traditional Chinese: 紫微斗數; pinyin: zǐwēidǒushù) are still used regularly in modern-day Chinese astrology. They do not rely on direct observations of the stars.
The Korean zodiac is identical to the Chinese one. The Vietnamese zodiac is almost identical to Chinese zodiac except the second animal is the Water Buffalo instead of the Ox, and the fourth animal is the Cat instead of the Rabbit. The Japanese have since 1873 celebrated the beginning of the new year on 1 January as per the Gregorian calendar. The Thai zodiac begins, not at Chinese New Year, but either on the first day of fifth month in the Thai lunar calendar, or during the Songkran festival (now celebrated every 13–15 April), depending on the purpose of the use.
St. Augustine (354–430) believed that the determinism of astrology conflicted with the Christian doctrines of man's free will and responsibility, and God not being the cause of evil, but he also grounded his opposition philosophically, citing the failure of astrology to explain twins who behave differently although conceived at the same moment and born at approximately the same time.
Some of the practices of astrology were contested on theological grounds by medieval Muslim astronomers such as Al-Farabi (Alpharabius), Ibn al-Haytham (Alhazen) and Avicenna. They said that the methods of astrologers conflicted with orthodox religious views of Islamic scholars, by suggesting that the Will of God can be known and predicted in advance. For example, Avicenna's 'Refutation against astrology', Risāla fī ibṭāl aḥkām al-nojūm, argues against the practice of astrology while supporting the principle that planets may act as agents of divine causation. Avicenna considered that the movement of the planets influenced life on earth in a deterministic way, but argued against the possibility of determining the exact influence of the stars. Essentially, Avicenna did not deny the core dogma of astrology, but denied our ability to understand it to the extent that precise and fatalistic predictions could be made from it. Ibn Qayyim Al-Jawziyya (1292–1350), in his Miftah Dar al-SaCadah, also used physical arguments in astronomy to question the practice of judicial astrology. He recognised that the stars are much larger than the planets, and argued:
And if you astrologers answer that it is precisely because of this distance and smallness that their influences are negligible, then why is it that you claim a great influence for the smallest heavenly body, Mercury? Why is it that you have given an influence to al-Ra's and al-Dhanab, which are two imaginary points [ascending and descending nodes]?
All forms of divination are to be rejected: recourse to Satan or demons, conjuring up the dead or other practices falsely supposed to "unveil" the future. Consulting horoscopes, astrology, palm reading, interpretation of omens and lots, the phenomena of clairvoyance, and recourse to mediums all conceal a desire for power over time, history, and, in the last analysis, other human beings, as well as a wish to conciliate hidden powers. They contradict the honor, respect, and loving fear that we owe to God alone.— Catechism of the Catholic Church
Scientific analysis and criticism
The scientific community rejects astrology as having no explanatory power for describing the universe, and considers it a pseudoscience.:1350 Scientific testing of astrology has been conducted, and no evidence has been found to support any of the premises or purported effects outlined in astrological traditions.:424; There is no proposed mechanism of action by which the positions and motions of stars and planets could affect people and events on Earth that does not contradict well understood, basic aspects of biology and physics.:249; Those who continue to have faith in astrology have been characterised as doing so "...in spite of the fact that there is no verified scientific basis for their beliefs, and indeed that there is strong evidence to the contrary."
Confirmation bias is a form of cognitive bias, a psychological factor that contributes to belief in astrology.:344;:180–181;:42–48 [a]:553 Astrology believers tend to selectively remember predictions that turn out to be true, and do not remember those that turn out false. Another, separate, form of confirmation bias also plays a role, where believers often fail to distinguish between messages that demonstrate special ability and those that do not.:180–181 Thus there are two distinct forms of confirmation bias that are under study with respect to astrological belief.:180–181
Under the criterion of falsifiability, first proposed by the philosopher of science Karl Popper, astrology is a pseudoscience. Popper regarded astrology as "pseudo-empirical" in that "it appeals to observation and experiment," but "nevertheless does not come up to scientific standards.":44 In contrast to scientific disciplines, astrology has not responded to falsification through experiment.:206
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.:401 Kuhn thought that, though astrologers had, historically, made predictions that categorically failed, this in itself does not make astrology unscientific, nor do attempts by astrologers to explain away failures by claiming that creating a horoscope is very difficult. Rather, in Kuhn's eyes, astrology is not science because it was always more akin to medieval medicine; astrologers 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.":401;:8 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.:8
The philosopher Paul Thagard asserts that astrology cannot 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.:228 To Thagard a further criterion of demarcation of science from pseudoscience is that the state-of-the-art must progress and that the community of researchers should be attempting to compare the current theory to alternatives, and not be "selective in considering confirmations and disconfirmations.":227–228 Progress is defined here as explaining new phenomena and solving existing problems, yet astrology has failed to progress having only changed little in nearly 2000 years.:228:549 To Thagard, astrologers are acting as though engaged in normal science believing that the foundations of astrology were well established despite the "many unsolved problems," and in the face of better alternative theories (psychology). For these reasons Thagard views astrology as pseudoscience.:228
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.:34
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."— Edward W. James:34
Astrology has not demonstrated its effectiveness in controlled studies and has no scientific validity.:85; Where it has made falsifiable predictions under controlled conditions, they have been falsified.:424 One famous experiment included 28 astrologers who were asked to match over a hundred natal charts to psychological profiles generated by the California Psychological Inventory (CPI) questionnaire. The double-blind experimental protocol used in this study was agreed upon by a group of physicists and a group of astrologers nominated by the National Council for Geocosmic Research, who advised the experimenters, helped ensure that the test was fair:420;:117 and helped draw the central proposition of natal astrology to be tested.:419 They also chose 26 out of the 28 astrologers for the tests (two more volunteered afterwards).:420 The study, published in Nature in 1985, found that predictions based on natal astrology were no better than chance, and that the testing "...clearly refutes the astrological hypothesis."
In 1955, the astrologer and psychologist Michel Gauquelin stated that though he had failed to find evidence that supported indicators like zodiacal signs and planetary aspects in astrology, he did find positive correlations between the diurnal positions of some planets and success in professions that astrology traditionally associates with those planets. The best-known of Gauquelin's findings is based on the positions of Mars in the natal charts of successful athletes and became known as the Mars effect.:213 A study conducted by seven French scientists attempted to replicate the claim, but found no statistical evidence.:213–214 They attributed the effect to selective bias on Gauquelin's part, accusing him of attempting to persuade them to add or delete names from their study.
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 number of births under astrologically undesirable conditions was also lower, indicating that parents choose dates and times to suit their beliefs. 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, where a nurse or doctor recorded the birth information.:116
Dean, a scientist and former astrologer, and psychologist Ivan Kelly conducted a large scale scientific test that involved more than one hundred cognitive, behavioural, physical, and other variables—but found no support for astrology. Furthermore, a meta-analysis pooled 40 studies that involved 700 astrologers and over 1,000 birth charts. Ten of the tests—which involved 300 participants—had the astrologers pick the correct chart interpretation out of a number of others that were not the astrologically correct chart interpretation (usually three to five others). When date and other obvious clues were removed, no significant results suggested there was any preferred chart.:190
Lack of mechanisms and consistency
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.:83 Most professional astrologers are paid to predict the future or describe a person's personality and life, but most horoscopes only make vague untestable statements that can apply to almost anyone.:83
Many astrologers claim that astrology is scientific, while some have proposed conventional causal agents such as electromagnetism and gravity. Scientists reject these mechanisms as implausible since, for example, the magnetic field, when measured from Earth, of a large but distant planet such as Jupiter is far smaller than that produced by ordinary household appliances.
Western astrology has taken the earth's axial precession (also called precession of the equinoxes) into account since Ptolemy's Almagest, so the "first point of Aries", the start of the astrological year, continually moves against the background of the stars. 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. Charpak and Broch, noting this, referred to astrology based on the tropical zodiac as being "...empty boxes that have nothing to do with anything and are devoid of any consistency or correspondence with the stars." Sole use of the tropical zodiac is inconsistent with references made, by the same astrologers, to the Age of Aquarius, which depends on when the vernal point enters the constellation of Aquarius.
Astrologers usually have only a small knowledge of astronomy, and often do not take into account basic principles—such as the precession of the equinoxes, which changes the position of the sun with time. They commented on the example of Élizabeth 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-year period there would be a difference greater than 780,000 miles.
Western politics and society
In the West, political leaders have sometimes consulted astrologers. For example, the British intelligence agency MI5 employed Louis de Wohl as an astrologer after claims surfaced that Adolf Hitler used astrology to time his actions. The War Office was "...interested to know what Hitler's own astrologers would be telling him from week to week." In fact, de Wohl's predictions were so inaccurate that he was soon labelled a "complete charlatan," and later evidence showed that Hitler considered astrology "complete nonsense." After John Hinckley's attempted assassination of US President Ronald Reagan, first lady Nancy Reagan commissioned astrologer Joan Quigley to act as the secret White House astrologer. However, Quigley's role ended in 1988 when it became public through the memoirs of former chief of staff, Donald Regan.
There was a boom in interest in astrology in the late 1960s. The sociologist Marcello Truzzi described three levels of involvement of "Astrology-believers" to account for its revived popularity in the face of scientific discrediting. He found that most astrology-believers did not claim it was a scientific explanation with predictive power. Instead, those superficially involved, knowing "next to nothing" about astrology's 'mechanics', read newspaper astrology columns, and could benefit from "tension-management of anxieties" and "a cognitive belief-system that transcends science." Those at the second level usually had their horoscopes cast and sought advice and predictions. They were much younger than those at the first level, and could benefit from knowledge of the language of astrology and the resulting ability to belong to a coherent and exclusive group. Those at the third level were highly involved and usually cast horoscopes for themselves. Astrology provided this small minority of astrology-believers with a "meaningful view of their universe and [gave] them an understanding of their place in it."[b] This third group took astrology seriously, possibly as a sacred canopy[further explanation needed], whereas the other two groups took it playfully and irreverently.
In 1953, the sociologist Theodor W. Adorno conducted a study of the astrology column of a Los Angeles newspaper as part of a project examining mass culture in capitalist society.:326 Adorno believed that popular astrology, as a device, invariably leads to statements that encouraged conformity—and that astrologers who go against conformity, by discouraging performance at work etc., risk losing their jobs.:327 Adorno concluded that astrology is a large-scale manifestation of systematic irrationalism, where individuals are subtly led—through flattery and vague generalisations—to believe that the author of the column is addressing them directly. Adorno drew a parallel with the phrase opium of the people, by Karl Marx, by commenting, "occultism is the metaphysic of the dopes.":329
A 2005 Gallup poll and a 2009 survey by the Pew Research Center reported that 25% of US adults believe in astrology. According to data released in the National Science Foundation's 2014 Science and Engineering Indicators study, "Fewer Americans rejected astrology in 2012 than in recent years." The NSF study noted that in 2012, "slightly more than half of Americans said that astrology was 'not at all scientific,' whereas nearly two-thirds gave this response in 2010. The comparable percentage has not been this low since 1983."
India and Japan
In India, there is a long-established and widespread belief in astrology. It is commonly used for daily life, particularly in matters concerning marriage and career, and makes extensive use of electional, horary and karmic astrology. Indian politics have also been influenced by astrology. It is still considered a branch of the Vedanga. In 2001, Indian scientists and politicians debated and critiqued a proposal to use state money to fund research into astrology, resulting in permission for Indian universities to offer courses in Vedic astrology.
In Japan, strong belief in astrology has led to dramatic changes in the fertility rate and the number of abortions in the years of Fire Horse. Adherents believe that women born in hinoeuma years are unmarriageable and bring bad luck to their father or husband. In 1966, the number of babies born in Japan dropped by over 25% as parents tried to avoid the stigma of having a daughter born in the hinoeuma year.
Literature and music
The fourteenth-century English poets John Gower and Geoffrey Chaucer both referred to astrology in their works, including Gower's Confessio Amantis and Chaucer's The Canterbury Tales. Chaucer commented explicitly on astrology in his Treatise on the Astrolabe, demonstrating personal knowledge of one area, judicial astrology, with an account of how to find the ascendant or rising sign.
In the sixteenth century, John Lyly's 1597 play, The Woman in the Moon, is wholly motivated by astrology, while Christopher Marlowe makes astrological references in his plays Doctor Faustus and Tamburlaine (both c. 1590), and Sir Philip Sidney refers to astrology at least four times in his romance The Countess of Pembroke's Arcadia (c. 1580). Edmund Spenser uses astrology both decoratively and causally in his poetry, revealing "...unmistakably an abiding interest in the art, an interest shared by a large number of his contemporaries." George Chapman's play, Byron's Conspiracy (1608), similarly uses astrology as a causal mechanism in the drama. William Shakespeare's attitude towards astrology is unclear, with contradictory references in plays including King Lear, Antony and Cleopatra, and Richard II. Shakespeare was familiar with astrology and made use of his knowledge of astrology in nearly every play he wrote, assuming a basic familiarity with the subject in his commercial audience. Outside theatre, the physician and mystic Robert Fludd practised astrology, as did the quack doctor Simon Forman. In Elizabethan England, "The usual feeling about astrology ... [was] that it is the most useful of the sciences."
In seventeenth century Spain, Lope de Vega, with a detailed knowledge of astronomy, wrote plays that ridicule astrology. In his pastoral romance La Arcadia (1598), it leads to absurdity; in his novela Guzman el Bravo (1624), he concludes that the stars were made for man, not man for the stars. Calderón de la Barca wrote the 1641 comedy Astrologo Fingido (The Pretended Astrologer); the plot was borrowed by the French playwright Thomas Corneille for his 1651 comedy Feint Astrologue.
The most famous piece of music influenced by astrology is the orchestral suite The Planets. Written by the British composer Gustav Holst (1874–1934), and first performed in 1918, the framework of The Planets is based upon the astrological symbolism of the planets. Each of the seven movements of the suite is based upon a different planet, though the movements are not in the order of the planets from the Sun. The composer Colin Matthews wrote an eighth movement entitled Pluto, the Renewer, first performed in 2000. In 1937, another British composer, Constant Lambert, wrote a ballet on astrological themes, called Horoscope. In 1974, the New Zealand composer Edwin Carr wrote The Twelve Signs: An Astrological Entertainment for orchestra without strings. Camille Paglia acknowledges astrology as an influence on her work of literary criticism Sexual Personae (1990).

In countries such as India, where only a small intellectual elite has been trained in Western physics, astrology manages to retain here and there its position among the sciences. Its continued legitimacy is demonstrated by the fact that some Indian universities offer advanced degrees in astrology. In the West, however, Newtonian physics and Enlightenment rationalism largely eradicated the widespread belief in astrology, yet Western astrology is far from dead, as demonstrated by the strong popular following it gained in the 1960s.

To optimise the chances of finding even remote relationships between date of birth and individual differences in personality and intelligence we further applied two different strategies. The first one was based on the common chronological concept of time (e.g. month of birth and season of birth). The second strategy was based on the (pseudo-scientific) concept of astrology (e.g. Sun Signs, The Elements, and astrological gender), as discussed in the book Astrology: Science or superstition? by Eysenck and Nias (1982).

Dante's interest in astrology has only slowly been gaining the attention it deserves. In 1940 Rudolf Palgen published his pioneering eighty-page "Dantes Sternglaube: Beiträge zur Erklärung des Paradiso", which concisely surveyed Dante's treatment of the planets and of the sphere of fixed stars; he demonstrated that it is governed by the astrological concept of the "children of the planets" (in each sphere the pilgrim meets souls whose lives reflected the dominant influence of that planet) and that in countless details the imagery of the Paradiso is derived from the astrological tradition. ... Like Palgen, he [Kay] argues (again, in more detail) that Dante adapted traditional astrological views to his own Christian ones; he finds this process intensified in the upper heavens.

This underlies the Barnum effect. Named after the 19th-century showman Phileas T. Barnum—whose circus provided "a little something for everyone"—it refers to the idea that people believe a statement about their personality that is vague or trivial if they think it derives from some systematic procedure tailored especially for them (Dickson & Kelly, 1985; Furnham & Schofield, 1987; Rogers & Soule, 2009; Wyman & Vyse, 2008). For example, the more birth detail is used in an astrological prediction or horoscope, the more credulous people tend to be (Furnham, 1991). However, confirmation bias means that people do not tend to pay attention to other information that might disconfirm the credibility of the predictions.

The literary interest in astrology, which had been on the increase in England throughout the fourteenth century, culminated in the works of Gower and Chaucer. Although references to astrology were already frequent in the romances of the fourteenth century, these still retained the signs of being foreign importations. It was only in the fifteenth century that astrological similes and embellishments became a matter of course in the literature of England.
Such innovations, one must confess, were due far more to Chaucer than to Gower. Gower, too, saw artistic possibilities in the new astrological learning, and promptly used these in his retelling of the Alexander legend—but he confined himself, for the most part, to a bald rehearsal of facts and theories. It is, accordingly, as a part of the long encyclopaedia of natural science that he inserted into his Confessio Amantis, and in certain didactic passages of the Vox Clamantis and the Mirour de l'Omme, that Astrology figures most largely in his works ... Gower's sources on the subject of astrology ... were Albumasar's Introductorium in Astronomiam, the Pseudo-Aristotelian Secretum Secretorum, Brunetto Latini's Trésor, and the Speculum Astronomiae ascribed to Albert the Great.
