Pseudohistory in the context of "White genocide conspiracy theory"

Each entry on these lists of common misconceptions is worded as a correction; the misconceptions themselves are implied rather than stated. These entries are concise summaries; the main subject articles can be consulted for more detail.

Common misconceptions are viewpoints or factoids that are often accepted as true, but which are actually false. They generally arise from conventional wisdom (such as old wives' tales), stereotypes, superstitions, fallacies, a misunderstanding of science, or the popularization of pseudoscience and pseudohistory. Some common misconceptions are also considered to be urban legends, and they are sometimes involved in moral panics.

Immanuel Velikovsky (/ˌvɛliˈkɒfski/; Russian: Иммануи́л Велико́вский, IPA: [ɪmənʊˈil vʲɪlʲɪˈkofskʲɪj]; 10 June [O.S. 29 May] 1895 – 17 November 1979) was a Russian-American psychoanalyst, writer, and catastrophist. He is the author of several books offering pseudohistorical interpretations of ancient history, including the U.S. bestseller Worlds in Collision published in 1950. Velikovsky's work is frequently cited as a canonical example of pseudoscience and has been used as an example of the demarcation problem.

His books use comparative mythology and ancient literary sources (including the Old Testament) to argue that Earth suffered catastrophic close contacts with other planets (principally Venus and Mars) in ancient history. In positioning Velikovsky among catastrophists including Hans Bellamy, Ignatius Donnelly, and Johann Gottlieb Radlof [de], the British astronomers Victor Clube and Bill Napier noted "... Velikovsky is not so much the first of the new catastrophists ...; he is the last in a line of traditional catastrophists going back to mediaeval times and probably earlier." Velikovsky argued that electromagnetic effects play an important role in celestial mechanics. He also proposed a revised chronology for ancient Egypt, Greece, Israel, and other cultures of the ancient Near East. The revised chronology aimed at explaining the so-called "dark age" of the eastern Mediterranean (c. 1100–750 BC) and reconciling biblical accounts with widely accepted archaeology and Egyptian chronology.

Leir was a legendary king of the Britons whose story was recounted by Geoffrey of Monmouth in his pseudohistorical 12th-century History of the Kings of Britain. According to Geoffrey's genealogy of the British dynasty, Leir reigned around the 8th century BC, around the time of the founding of Rome. The story was modified and retold by William Shakespeare in his Jacobean tragedy King Lear.

Ignatius Loyola Donnelly (November 3, 1831 – January 1, 1901) was an American Congressman, populist writer, and pseudoscientist. He is known primarily now for his fringe theories concerning Atlantis, Catastrophism (especially the idea of an ancient impact event affecting ancient civilizations), and Shakespearean authorship. These works are widely regarded as examples of pseudoscience and pseudohistory. Donnelly's work corresponds to the writings of late-19th and early-20th century figures such as Helena Blavatsky, Rudolf Steiner, and James Churchward.

Creation science or scientific creationism is a pseudoscientific form of Young Earth creationism which claims to offer scientific arguments for certain literalist and inerrantist interpretations of the Bible. It is often presented without overt faith-based language, but instead relies on reinterpreting scientific results to argue that various myths in the Book of Genesis and other select biblical passages are scientifically valid. The most commonly advanced ideas of creation science include special creation based on the Genesis creation narrative and flood geology based on the Genesis flood narrative. Creationists also claim they can disprove or reexplain a variety of scientific facts, theories and paradigms of geology, cosmology, biological evolution, archaeology, history, and linguistics using creation science. Creation science was foundational to intelligent design.

The overwhelming consensus of the scientific community is that creation science fails to qualify as scientific because it lacks empirical support, supplies no testable hypotheses, and resolves to describe natural history in terms of scientifically untestable supernatural causes. Courts, most often in the United States where the question has been asked in the context of teaching the subject in public schools, have consistently ruled since the 1980s that creation science is a religious view rather than a scientific one. Historians, philosophers of science and skeptics have described creation science as a pseudoscientific attempt to map the Bible into scientific facts. Professional biologists have criticized creation science for being unscholarly, and even as a dishonest and misguided sham, with extremely harmful educational consequences.

White supremacy is the belief that white people are superior to those of other races. The belief favors the maintenance and defense of any power and privilege held by white people. White supremacy has roots in the now-discredited doctrine of scientific racism and was a key justification for European colonialism.

As a political ideology, it imposes and maintains cultural, social, political, historical or institutional domination by white people and non-white supporters. In the past, this ideology had been put into effect through socioeconomic and legal structures such as the Atlantic slave trade, European colonial labor and social practices, the Scramble for Africa, Jim Crow laws in the United States, the activities of the Native Land Court in New Zealand, the White Australia policies from the 1890s to the mid-1970s, and apartheid in South Africa. This ideology is also today present among neo-Confederates.

In historiography, historical revisionism is the reinterpretation of a historical account. It involves challenging the orthodox (established, accepted or traditional) scholarly views or narratives regarding a historical event, timespan, or phenomenon by introducing contrary evidence or reinterpreting the motivations of the people involved. Revision of the historical record can reflect new discoveries of fact, evidence, and interpretation as they come to light. The process of historical revision is a common, necessary, and usually uncontroversial process which develops and refines the historical record to make it more complete and accurate.

One form of historical revisionism involves denying the moral significance or accuracy of the historical record. This type of historical revisionism is called historical negationism, and is contentious as it often includes denying the veracity of genuine documents, or deliberately manipulating statistical data to reach predetermined conclusions. The destruction or alteration of cultural heritage sites is also considered a form of illegitimate historical revisionism when it serves to deny the cultural or historical claims of ethnic groups. Negationists may use the term "revisionism" to portray their pseudoscholarship as legitimate, especially in the context of genocide denial.
