Turkey illusion is a cognitive bias describing the surprise resulting from a break in a trend, if one does not know the causes or the framework conditions for this trend. [1] The concept was first introduced by Bertrand Russell [2] to illustrate a problem with inductive reasoning.
Relevant disciplines for uncovering such biases include psychology and behavioral economics. [1]
In a variation from Russell's original, a turkey designated for Thanksgiving is fed and cared for every day until it is slaughtered. [3] [4] With each feeding, its certainty or confidence that nothing will happen to it increases, based on past experience. From the turkey's point of view, the certainty that it will be fed and cared for again the next day is greatest on the night before it dies, of all days. Nevertheless, it is slaughtered that day, by the very person who cared for it.
The story appears in Bertrand Russell's 1912 The Problems of Philosophy as relating to a chicken:
The man who has fed the chicken every day throughout its life at last wrings its neck instead, showing that more refined views as to the uniformity of nature would have been useful to the chicken.
The slaughter comes as a complete surprise to the turkey, who - in anthropomorphic formulation - "only extrapolates a trend" and "does not recognize the impending trend break". To recognize this trend break, the turkey would have had to find out the causes of the trend. By doing so, it would have known about the motivational state of the human who feeds it every day. In order to "think outside the box" and leave known or familiar thought patterns, creativity and the ability to change perspectives are necessary. This was not possible for the turkey due to insufficient information. [5]
Agnosticism is the view or belief that the existence of God, the divine, or the supernatural is either unknowable in principle or currently unknown in fact. It can also mean an apathy towards such religious belief and refer to personal limitations rather than a worldview. Another definition is the view that "human reason is incapable of providing sufficient rational grounds to justify either the belief that God exists or the belief that God does not exist."
Bertrand Arthur William Russell, 3rd Earl Russell, was a British mathematician, logician, philosopher, and public intellectual. He had influence on mathematics, logic, set theory, and various areas of analytic philosophy.
Poultry are domesticated birds kept by humans for the purpose of harvesting animal products such as meat, eggs or feathers. The practice of raising poultry is known as poultry farming. These birds are most typically members of the superorder Galloanserae (fowl), especially the order Galliformes. The term also includes waterfowls of the family Anatidae but does not include wild birds hunted for food known as game or quarry.
Solipsism is the philosophical idea that only one's mind is sure to exist. As an epistemological position, solipsism holds that knowledge of anything outside one's own mind is unsure; the external world and other minds cannot be known and might not exist outside the mind.
Islamic dietary laws are laws that Muslims follow in their diet. Islamic jurisprudence specifies which foods are halal and which are haram. The dietary laws are found in the Quran, the holy book of Islam, as well as in collections of traditions attributed to the Islamic prophet Muhammad.
The problem of induction is a philosophical problem that questions the rationality of predictions about unobserved things based on previous observations. These inferences from the observed to the unobserved are known as "inductive inferences". David Hume, who first formulated the problem in 1739, argued that there is no non-circular way to justify inductive inferences, while acknowledging that everyone does and must make such inferences.
Beak trimming, or beak conditioning, is the partial removal of the beak of poultry, especially layer hens and turkeys, although it is also be performed on some quail and ducks. When multiple birds are confined in small spaces due to farming practices, they are more likely to hurt each other through pecking. Beak trimming aims to avoid damage done by pecking, although the practice is criticized by animal welfare organizations and banned in several European countries. Beak trimming is most common in egg-laying strains of chickens. In some countries, such as the United States, turkeys routinely have their beaks trimmed. In the UK, only 10% of turkeys are beak trimmed.
Inductive reasoning is any of various methods of reasoning in which broad generalizations or principles are derived from a body of observations. This article is concerned with the inductive reasoning other than deductive reasoning, where the conclusion of a deductive argument is certain given the premises are correct; in contrast, the truth of the conclusion of an inductive argument is at best probable, based upon the evidence given.
Logical atomism is a philosophical view that originated in the early 20th century with the development of analytic philosophy. It holds that the world consists of ultimate logical "facts" that cannot be broken down any further, each of which can be understood independently of other facts.
The theory of descriptions is the philosopher Bertrand Russell's most significant contribution to the philosophy of language. It is also known as Russell's theory of descriptions. In short, Russell argued that the syntactic form of descriptions is misleading, as it does not correlate their logical and/or semantic architecture. While descriptions may seem like fairly uncontroversial phrases, Russell argued that providing a satisfactory analysis of the linguistic and logical properties of a description is vital to clarity in important philosophical debates, particularly in semantic arguments, epistemology and metaphysical elements.
Free range denotes a method of farming husbandry where the animals, for at least part of the day, can roam freely outdoors, rather than being confined in an enclosure for 24 hours each day. On many farms, the outdoors ranging area is fenced, thereby technically making this an enclosure, however, free range systems usually offer the opportunity for the extensive locomotion and sunlight that is otherwise prevented by indoor housing systems. Free range may apply to meat, eggs or dairy farming.
John Russell, Viscount Amberley, was a British politician and writer. He was the eldest son of John Russell, who twice served as Prime Minister of the United Kingdom, and father of the philosopher Bertrand Russell. Amberley is known for his unorthodox views on religion and for his active support of birth control and women's suffrage, which contributed to the end of his short career as Liberal Member of Parliament.
A gapeworm, also known as a red worm and forked worm, is a parasitic nematode worm that infects the tracheas of certain birds. The resulting disease, known as "gape", occurs when the worms clog and obstruct the airway. The worms are also known as "red worms" or "forked worms" due to their red color and the permanent procreative conjunction of males and females. Gapeworms are common in young, domesticated chickens and turkeys.
Equine nutrition is the feeding of horses, ponies, mules, donkeys, and other equines. Correct and balanced nutrition is a critical component of proper horse care.
Animal slaughter is the killing of animals, usually referring to killing domestic livestock. It is estimated that each year, 80 billion land animals are slaughtered for food. Most animals are slaughtered for food; however, they may also be slaughtered for other reasons such as for harvesting of pelts, being diseased and unsuitable for consumption, or being surplus for maintaining a breeding stock. Slaughter typically involves some initial cutting, opening the major body cavities to remove the entrails and offal but usually leaving the carcass in one piece. Such dressing can be done by hunters in the field or in a slaughterhouse. Later, the carcass is usually butchered into smaller cuts.
Intensive animal farming, industrial livestock production, and macro-farms, also known as factory farming, is a type of intensive agriculture, specifically an approach to animal husbandry designed to maximize production while minimizing costs. To achieve this, agribusinesses keep livestock such as cattle, poultry, and fish at high stocking densities, at large scale, and using modern machinery, biotechnology, and global trade. The main products of this industry are meat, milk and eggs for human consumption.
Poultry farming is the form of animal husbandry which raises domesticated birds such as chickens, ducks, turkeys and geese to produce meat or eggs for food. Poultry – mostly chickens – are farmed in great numbers. More than 60 billion chickens are killed for consumption annually. Chickens raised for eggs are known as layers, while chickens raised for meat are called broilers.
The aspects of Bertrand Russell's views on philosophy cover the changing viewpoints of philosopher and mathematician Bertrand Russell (1872–1970), from his early writings in 1896 until his death in February 1970.
Karen Dawn is an American animal rights and welfare advocate and writer.
"Free Thought and Official Propaganda" is a speech delivered in 1922 by Bertrand Russell on the importance of unrestricted freedom of expression in society, and the problem of the state and political class interfering in this through control of education, fines, economic leverage, and distortion of evidence.
