Pseudoscience
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. The demarcation between science and pseudoscience has scientific, philosophical, and political implications. Philosophers debate the nature of science and the general criteria for drawing the line between scientific theories and pseudoscientific beliefs, but there is widespread agreement "that creationism, astrology, homeopathy, Kirlian photography, dowsing, ufology, ancient astronaut theory, Holocaust den ...

Astrology
Astrology is a range of Divination, divinatory practices, recognized as pseudoscientific since the 18th century, that propose that information about human affairs and terrestrial events may be discerned by studying the apparent positions of Celestial objects in astrology, celestial objects. Different cultures have employed forms of astrology since at least the 2nd millennium BCE, these practices having originated in Calendrical calculation, calendrical systems used to predict seasonal shifts and to interpret celestial cycles as signs of divine communications. Most, if not all, cultures have attached importance to what they observed in the sky, and some—such as the Hindu astrology, Hindus, Chinese astrology, Chinese, and the Maya civilization, 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, fr ...

Homeopathy
Homeopathy or homoeopathy is a pseudoscientific system of alternative medicine. It was conceived in 1796 by the German physician Samuel Hahnemann. Its practitioners, called homeopaths or homeopathic physicians, believe that a substance that causes symptoms of a disease in healthy people can cure similar symptoms in sick people; this doctrine is called ''similia similibus curentur'', or "like cures like". Homeopathic preparations are termed ''remedies'' and are made using homeopathic dilution. In this process, the selected substance is repeatedly diluted until the final product is chemically indistinguishable from the diluent. Often not even a single molecule of the original substance can be expected to remain in the product. Between each dilution homeopaths may hit and/or shake the product, claiming this makes the diluent "remember" the original substance after its removal. Practitioners claim that such preparations, upon oral intake, can treat or cure disease. All relevant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Demarcation Problem
In philosophy of science and epistemology, the demarcation problem is the question of how to distinguish between science and non-science. It also examines the boundaries between science, pseudoscience and other products of human activity, like art and literature and beliefs.. Alternative source/ref> The debate continues after more than two millennia of dialogue among philosophers of science and Scientist, scientists in various fields. The debate has consequences for what can be termed "scientific" in topics such as education and public policy. The ancients An early attempt at demarcation can be seen in the efforts of Greek natural philosophers and medical practitioners to distinguish their methods and their accounts of nature from the mythological or mystical accounts of their predecessors and contemporaries. G. E. R. Lloyd noted that there was a sense in which the groups engaged in various forms of inquiry into nature attempt to "legitimate their own positions", laying " ...

Ufology
Ufology, sometimes written UFOlogy ( or ), is the investigation of unidentified flying objects (UFOs) by people who believe that they may be of extraordinary claims, extraordinary origins (most frequently of extraterrestrial hypothesis, extraterrestrial alien visitors). While there are instances of List of investigations of UFOs by governments, government, List of UFO organizations, private, and fringe science investigations of UFOs, ufology is generally regarded by Skeptical movement, skeptics and Science education, science educators as an example of pseudoscience. Etymology Ufology is a neologism derived from ''UFO'' (a term apparently coined by Edward J. Ruppelt), and is derived from appending the acronym UFO with the suffix ''-logy'' (from the Ancient Greek ''-λογία'' (''-logia'')). Early uses of ufology include an article in ''Fantastic Universe'' (1957) and a 1958 presentation for the UFO "research organization" The Planetary Center. Historical background The roots ...

Phrenological Organs, 1887 Wellcome L0001965
Phrenology 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 influentia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holocaust Denial
Historical negationism, Denial of the Holocaust is an antisemitic conspiracy theory that asserts that the genocide of Jews by the Nazi Party, Nazis is a fabrication or exaggeration. It includes making one or more of the following false claims: *Nazi Germany's "Final Solution" was aimed only at Expulsions and exoduses of Jews, deporting Jews from the territory of the Third Reich and did not include their extermination. *Nazi authorities did not use extermination camps and gas chambers for the mass murder of Jews. *The actual number of Jews murdered is significantly lower than the accepted figure of approximately six million. *The Holocaust is a hoax perpetrated by the Allies of World War II, Allies, International Jewish conspiracy, Jews, or the Soviet Union. The methodologies of Holocaust deniers are based on a predetermined conclusion that ignores Evidence and documentation for the Holocaust, overwhelming historical evidence to the contrary. Scholars use the term ''Denialism, de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Junk Science
Junk science is spurious or fraudulent scientific data, research, or analysis. The concept is often invoked in political and legal contexts where facts and scientific results have a great amount of weight in making a determination. It usually conveys a pejorative connotation that the research has been untowardly driven by political, ideological, financial, or otherwise unscientific motives. The concept was popularized in the 1990s in relation to expert testimony in civil litigation. More recently, invoking the concept has been a tactic to criticize research on the harmful environmental or public health effects of corporate activities, and occasionally in response to such criticism. In some contexts, junk science is counterposed to the "sound science" or "solid science" that favors one's own point of view. Junk science has been criticized for undermining public trust in real science. Junk science is not the same as pseudoscience. Definition Junk science has been defined as: * " ...

Ancient Astronauts
Ancient astronauts (or ancient aliens) refers to a Pseudoscience, pseudoscientific set of beliefs that hold that Extraterrestrial intelligence, intelligent Extraterrestrial life, extraterrestrial beings (alien astronauts) visited Earth and made contact with humans in Ancient history, antiquity and Prehistory, prehistoric times. Proponents of the theory suggest that this contact influenced the development of modern cultures, technologies, religions, and human biology. A common position is that Deity, deities from most (if not all) religions are extraterrestrial in origin, and that advanced technologies brought to Earth by ancient astronauts were interpreted as evidence of divine status by early humans. The idea that ancient astronauts existed and visited Earth is not taken seriously by academics and Archaeology, archaeologists, who identify such claims as Pseudoarchaeology, pseudoarchaeological or unscientific. It has received no credible attention in peer review, peer-reviewe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climate Change Denial
Climate change denial (also global warming denial) is a form of science denial characterized by rejecting, refusing to acknowledge, disputing, or fighting the scientific consensus on climate change. Those promoting denial commonly use rhetorical tactics to give the appearance of a scientific controversy where there is none. Climate change denial includes unreasonable doubts about the extent to which climate change is caused by humans, its effects on nature and human society, and the potential of adaptation to global warming by human actions. To a lesser extent, climate change denial can also be implicit when people accept the science but fail to reconcile it with their belief or action. Several studies have analyzed these positions as forms of denialism, pseudoscience, or propaganda. Many issues that are settled in the scientific community, such as human responsibility for climate change, remain the subject of politically or economically motivated attempts to downplay, ...

Fads And Fallacies In The Name Of Science
''Fads and Fallacies in the Name of Science'' (1957)—originally published in 1952 as ''In the Name of Science: An Entertaining Survey of the High Priests and Cultists of Science, Past and Present''—was Martin Gardner's second book. A survey of what it described as pseudosciences and cult beliefs, it became a founding document in the nascent scientific skepticism movement. Michael Shermer said of it: "Modern skepticism has developed into a science-based movement, beginning with Martin Gardner's 1952 classic". The book debunks what it characterises as pseudoscience and the pseudo-scientists who propagate it. Contents Synopsis ''Fads and Fallacies in the Name of Science'' starts with a brief survey of the spread of the ideas of "cranks" and "pseudo-scientists", attacking the credulity of the popular press and the irresponsibility of publishing houses in helping to propagate these ideas. Cranks often cite historical cases where ideas were rejected which are now accepted as righ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Science Education
Science education is the teaching and learning of science to school children, college students, or adults within the general public. The field of science education includes work in science content, science process (the scientific method), some social science, and some teaching pedagogy. The standards for science education provide expectations for the development of understanding for students through the entire course of their K–12 (education), K-12 education and beyond. The traditional subjects included in the standards are Physical science, physical, Life science, life, Earth science, earth, space science, space, and human sciences. Historical background The first person credited with being employed as a science teacher in a British public school (privately funded), public school was William Sharp (homeopath), William Sharp, who left the job at Rugby School in 1850 after establishing science to the curriculum. Sharp is said to have established a model for science to be taug ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dowsing
Dowsing is a type of divination employed in attempts to locate ground water, buried metals or ores, gemstones, Petroleum, oil, claimed radiations (radiesthesia),As translated from one preface of the Kassel experiments, "roughly 10,000 active dowsers in Germany ''alone'' can generate a conservatively-estimated annual revenue of more than 100 million DM (US$50 million)"''GWUP-Psi-Tests 2004: Keine Million Dollar für PSI-Fähigkeiten'' (in German) an. Grave (burial), gravesites, malign "earth vibrations" and many other objects and materials without the use of a Scientific instrument, scientific apparatus. It is also known as divining (especially in water divining), doodlebugging (particularly in the United States, in searching for petroleum or treasure) or water finding, or water witching (in the United States). A Y-shaped twig or rod, or two L-shaped ones, called dowsing rods or divining rods are normally used, and the motion of these are said to reveal the location of the target ...
