The history of pseudoscience is the study of pseudoscientific theories over time. A pseudoscience is a set of ideas that presents itself as science, while it does not meet the criteria to properly be called such. [1] [2]

Distinguishing between proper science and pseudoscience is sometimes difficult. One popular proposal for demarcation between the two is the falsification criterion, most notably contributed to by the philosopher Karl Popper. In the history of pseudoscience it can be especially hard to separate the two, because some sciences developed from pseudosciences. An example of this is the science chemistry, which traces its origins from the protoscience of alchemy.

The vast diversity in pseudosciences further complicates the history of pseudoscience. Some pseudosciences originated in the pre-scientific era, such as astrology and acupuncture. Others developed as part of an ideology, such as Lysenkoism, or as a response to perceived threats to an ideology. An example of this is creationism, which was developed as a response to the scientific theory of evolution.

Despite failing to meet proper scientific standards, many pseudosciences survive. This is usually due to a persistent core of devotees who refuse to accept scientific criticism of their beliefs, or due to popular misconceptions. Sheer popularity is also a factor, as is attested by astrology which remains popular despite being rejected by a large majority of scientists. [3] [4] [5] [6]

Among the most notable developments in the history of pseudoscience in the 19th century are the rise of Spiritualism (traced in America to 1848), homeopathy (first formulated in 1796), and phrenology (developed around 1800). Another popular pseudoscientific belief that arose during the 19th century was the idea that there were canals visible on Mars. A relatively mild Christian fundamentalist backlash against the scientific theory of evolution foreshadowed subsequent events in the 20th century.

The study of bumps and fissures in people's skulls to determine their character, phrenology , was originally considered a science. It influenced psychiatry and early studies into neuroscience. [7] As science advanced, phrenology was increasingly viewed as a pseudoscience. Halfway through the 19th century, the scientific community had prevailingly abandoned it, [8] although it was not comprehensively tested until much later. [9]

Halfway through the century, iridology was invented by the Hungarian physician Ignaz von Peczely. [10] The theory would remain popular throughout the 20th century as well. [11]

Spiritualism (sometimes referred to as "Modern Spiritualism" or "Spiritism") [12] or "Modern American Spiritualism" [13] grew phenomenally during the period. The American version of this movement has been traced to the Fox sisters who in 1848 began claiming the ability to communicate with the dead. [14] The religious movement would remain popular until the 1920s, when renowned magician Harry Houdini began exposing famous mediums and other performers as frauds (see also Harry Houdini#Debunking spiritualists). While the religious beliefs of Spiritualism are not presented as science, and thus are not properly considered pseudoscientific, the movement did spawn numerous pseudoscientific phenomena such as ectoplasm and spirit photography.

The principles of homeopathy were first formulated in 1796, by German physician Samuel Hahnemann. At the time, mainstream medicine was a primitive affair and still made use of techniques such as bloodletting. Homeopathic medicine by contrast consisted of extremely diluted substances, which meant that patients basically received water. Compared to the damage often caused by conventional medicine, this was an improvement. [15] During the 1830s homeopathic institutions and schools spread across the US and Europe. [16] Despite these early successes, homeopathy was not without its critics. [17] Its popularity was on the decline before the end of the 19th century, though it has been revived in the 20th century.

The supposed Martian canals were first reported in 1877, by the Italian astronomer Giovanni Schiaparelli. The belief in them peaked in the late 19th century, but was widely discredited in the beginning of the 20th century.

The publication of Atlantis: The Antediluvian World by politician and author Ignatius L. Donnelly in 1882, renewed interest in the ancient idea of Atlantis . This highly advanced society supposedly existed several millennia before the rise of civilizations like Ancient Egypt. It was first mentioned by Plato, as a literary device in two of his dialogues. Other stories of lost continents, such as Mu and Lemuria also arose during the late 19th century.

In 1881 the Dutch Vereniging tegen de Kwakzalverij (English: Society against Quackery) was formed to oppose pseudoscientific trends in medicine. It is still active.

20th century

Among the most notable developments to pseudoscience in the 20th century are the rise of Creationism, the demise of Spiritualism, and the first formulation of ancient astronaut theories.

Reflexology , the idea that an undetectable life force connects various parts of the body to the feet and sometimes the hands and ears, was introduced in the US in 1913 as 'zone therapy'. [18] [19]

Creationism arose during the 20th century as a result of various other historical developments. When the modern evolutionary synthesis overcame the eclipse of Darwinism in the first half of the 20th century, American fundamentalist Christians began opposing the teaching of the theory of evolution in public schools. They introduced numerous laws to this effect, one of which was notoriously upheld by the Scopes Trial. In the second half of the century the Space Race caused a renewed interest in science and worry that the USA was falling behind on the Soviet Union. Stricter science standards were adopted and led to the re-introduction of the theory of evolution in the curriculum. The laws against teaching evolution were now ruled unconstitutional, because they violated the separation of church and state. Attempting to evade this ruling, the Christian fundamentalists produced a supposedly secular alternative to evolution, Creationism. Perhaps the most influential publication of this new pseudoscience was The Genesis Flood by young earth creationists John C. Whitcomb and Henry M. Morris.

The dawn of the space age also inspired various versions of ancient astronaut theories . While differences between the specific theories exists, they share the idea that intelligent extraterrestrials visited Earth in the distant past and made contact with then living humans. Popular authors, such as Erich von Däniken and Zecharia Sitchin, began publishing in the 1960s. Among the most notable publications in the genre is Chariots of the Gods? , which appeared in 1968.

Late in the 20th century several prominent skeptical foundations were formed to counter the growth of pseudosciences. In the US, the most notable of these are, in chronological order, the Center for Inquiry (1991), The Skeptics Society (1992), the James Randi Educational Foundation (1996), and the New England Skeptical Society (1996). The Committee for Skeptical Inquiry, which has similar goals, had already been founded in 1976. It became part of the Center for Inquiry as part of the foundation of the latter in 1991. In the Netherlands Stichting Skepsis was founded in 1987.

21st century

At the beginning of the 21st century, a variety of pseudoscientific theories remain popular and new ones continue to crop up.

The Flat Earth is the idea that the Earth is flat. It is believed to have existed for thousands of years, but studies show this is a relatively new theory that begun in the 1990s when the internet starting up allowed such ideas to spread much quicker.

Creationism, in the form of Intelligent Design , suffered a major legal defeat in the Kitzmiller v. Dover Area School District trial. Judge John E. Jones III ruled that Intelligent Design is inseparable from Creationism, and its teaching in public schools violates the Establishment Clause of the First Amendment. The trial sparked much interest, and was the subject of several documentaries including the award-winning NOVA production Judgment Day: Intelligent Design on Trial (2007).

The pseudoscientific idea that vaccines cause autism originated in the 1990s, but became prominent in the media during the first decade of the 21st century. Despite a broad scientific consensus against the idea that there is a link between vaccination and autism, [20] [21] [22] [23] [24] several celebrities have joined the debate. Most notable of these is Jenny McCarthy, whose son has autism. In February 2009, surgeon Andrew Wakefield, who published the original research supposedly indicating a link between vaccines and autism, was reported to have fixed the data by The Sunday Times. [25] A hearing by the General Medical Council began in March 2007, examining charges of professional misconduct. On 24 May 2010, he was struck off the United Kingdom medical register, effectively banning him from practicing medicine in Britain.

The most notable development in the ancient astronauts genre was the opening of Erich von Däniken's Mystery Park in 2003. While the park had a good first year, the number of visitors was much lower than the expected 500,000 a year. This caused financial difficulties, which led to the closure of the park in 2006. [26]

<span class="mw-page-title-main">Pseudoscience</span> Unscientific claims wrongly presented as scientific

Pseudoscience consists of statements, beliefs, or practices that claim to be both scientific and factual but are incompatible with the scientific method. Pseudoscience is often characterized by contradictory, exaggerated or unfalsifiable claims; reliance on confirmation bias rather than rigorous attempts at refutation; lack of openness to evaluation by other experts; absence of systematic practices when developing hypotheses; and continued adherence long after the pseudoscientific hypotheses have been experimentally discredited. It is not the same as junk science.

<span class="mw-page-title-main">Phrenology</span> Pseudoscientific study of human characteristics according to shape of the skull

Phrenology or craniology is a pseudoscience that involves the measurement of bumps on the skull to predict mental traits. It is based on the concept that the brain is the organ of the mind, and that certain brain areas have localized, specific functions or modules. It was said that the brain was composed of different muscles, so those that were used more often were bigger, resulting in the different skull shapes. This provided reasoning for the common presence of bumps on the skull in different locations. The brain "muscles" not being used as frequently remained small and were therefore not present on the exterior of the skull. Although both of those ideas have a basis in reality, phrenology generalizes beyond empirical knowledge in a way that departs from science. The central phrenological notion that measuring the contour of the skull can predict personality traits is discredited by empirical research. Developed by German physician Franz Joseph Gall in 1796, the discipline was influential in the 19th century, especially from about 1810 until 1840. The principal British centre for phrenology was Edinburgh, where the Edinburgh Phrenological Society was established in 1820.

The biorhythm theory is the pseudoscientific idea that peoples' daily lives are significantly affected by rhythmic cycles with periods of exactly 23, 28 and 33 days, typically a 23-day physical cycle, a 28-day emotional cycle, and a 33-day intellectual cycle. The idea was developed by Wilhelm Fliess in the late 19th century, and was popularized in the United States in the late 1970s. The proposal has been independently tested and, consistently, no validity for it has been found.

Naturopathy, or naturopathic medicine, is a form of alternative medicine. A wide array of practices branded as "natural", "non-invasive", or promoting "self-healing" are employed by its practitioners, who are known as naturopaths. Difficult to generalize, these treatments range from the pseudoscientific and thoroughly discredited, like homeopathy, to the widely accepted, like certain forms of psychotherapy. The ideology and methods of naturopathy are based on vitalism and folk medicine rather than evidence-based medicine, although practitioners may use techniques supported by evidence. The ethics of naturopathy have been called into question by medical professionals and its practice has been characterized as quackery.

<span class="mw-page-title-main">Scientific skepticism</span> Questioning of claims lacking empirical evidence

Scientific skepticism or rational skepticism, sometimes referred to as skeptical inquiry, is a position in which one questions the veracity of claims lacking empirical evidence. In practice, the term most commonly refers to the examination of claims and theories that appear to be beyond mainstream science, rather than the routine discussions and challenges among scientists. Scientific skepticism differs from philosophical skepticism, which questions humans' ability to claim any knowledge about the nature of the world and how they perceive it, and the similar but distinct methodological skepticism, which is a systematic process of being skeptical about the truth of one's beliefs.

This list includes well-known general theories in science and pre-scientific natural philosophy and natural history that have since been superseded by other scientific theories. Many discarded explanations were once supported by a scientific consensus, but replaced after more empirical information became available that identified flaws and prompted new theories which better explain the available data. Pre-modern explanations originated before the scientific method, with varying degrees of empirical support. Similarly, this list also includes superseded well-known general mathematical results.

A debunker is a person or organization that exposes or discredits claims believed to be false, exaggerated, or pretentious. The term is often associated with skeptical investigation of controversial topics such as UFOs, claimed paranormal phenomena, cryptids, conspiracy theories, alternative medicine, religion, or exploratory or fringe areas of scientific or pseudoscientific research.
