Folk science (also known as "folk knowledge" or "folk classification" (not to be confused with Folk classification, a method of classifying sedimentary rocks named after Robert L. Folk) describes ways of understanding and predicting the natural and social world, without the use of formalized, rigorous, methodologies (see Scientific method). [1] One could label all understanding of nature predating the Greeks as "folk science". Folk science is often positioned in contrast to mechanistic or “clockwork” understandings of the world, where the function of each part and the relationship of all parts to each other is known in detail. [2] [3]
It is unclear how folk science develops in humans. However, even children as young as 8 months old have been shown to understand some root concepts of folk biology. [4] Children's understanding does shift as they age, with the system of inferences they use developing as they grow. [2]
Folk science is often accepted as "common wisdom" in a given culture, and people often don’t realize that their explanations and understandings rely on folk science. [3] [5] While this is common in children, even adults tend to believe they have a more complete understanding of mechanisms than they really do. Because folk science is something people, even children, do naturally, scientists are not exempt. [6] Folk science makes appearances in the theories of professional scientists. Anthropological studies of scientists show that their theories often stem from models with gaps, deductions, and analogies. While these simplifications and gaps are not part of the scientific method, they do often work and scientific advances continue to use folk scientific methods. In some cases, researchers might look deliberately to folk methods to augment or improve their own. [7] Several notable of folk science intuition (such as the world being flat, or the sun revolving around the Earth, clarify why it is important to continue to use the scientific method to gather data to confirm or deny folk scientific theories. [8]
Formal sciences, due to their thorough permeation of society, can ultimately influence folk sciences. [2] An example would be the concept of genetics, which is familiar to most adults in the 21st century, but at the level of a layperson. This leads to different inferences and folk scientific conclusions than those that would have been reached by a population without that knowledge. However, some kinds of folk science exist in all cultures. [9] Folk biology, for example, is similar in all human societies. These similarities include what groups plants and animals are grouped into, and the hierarchies of these groups (such as “oaks” being a group of plants which is within the “tree” group). It also includes the ability to make inferences about some organisms based on other, similarly categorized, organisms.
Cognitive science is the interdisciplinary, scientific study of the mind and its processes. It examines the nature, the tasks, and the functions of cognition. Mental faculties of concern to cognitive scientists include language, perception, memory, attention, reasoning, and emotion; to understand these faculties, cognitive scientists borrow from fields such as linguistics, psychology, artificial intelligence, philosophy, neuroscience, and anthropology. The typical analysis of cognitive science spans many levels of organization, from learning and decision to logic and planning; from neural circuitry to modular brain organization. One of the fundamental concepts of cognitive science is that "thinking can best be understood in terms of representational structures in the mind and computational procedures that operate on those structures."
In biology, taxonomy is the scientific study of naming, defining (circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum, class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms.
Zoology is the scientific study of animals. Its studies include the structure, embryology, classification, habits, and distribution of all animals, both living and extinct, and how they interact with their ecosystems. Zoology is one of the primary branches of biology. The term is derived from Ancient Greek ζῷον, zōion ('animal'), and λόγος, logos.
Essentialism is the view that objects have a set of attributes that are necessary to their identity. In early Western thought, Platonic idealism held that all things have such an "essence"—an "idea" or "form". In Categories, Aristotle similarly proposed that all objects have a substance that, as George Lakoff put it, "make the thing what it is, and without which it would be not that kind of thing". The contrary view—non-essentialism—denies the need to posit such an "essence". Essentialism has been controversial from its beginning. In the Parmenides dialogue, Plato depicts Socrates questioning the notion, suggesting that if we accept the idea that every beautiful thing or just action partakes of an essence to be beautiful or just, we must also accept the "existence of separate essences for hair, mud, and dirt".
Primatology is the scientific study of non-human primates. It is a diverse discipline at the boundary between mammalogy and anthropology, and researchers can be found in academic departments of anatomy, anthropology, biology, medicine, psychology, veterinary sciences and zoology, as well as in animal sanctuaries, biomedical research facilities, museums and zoos. Primatologists study both living and extinct primates in their natural habitats and in laboratories by conducting field studies and experiments in order to understand aspects of their evolution and behavior.
Holism in science, holistic science, or methodological holism is an approach to research that emphasizes the study of complex systems. Systems are approached as coherent wholes whose component parts are best understood in context and in relation to both each other and to the whole. Holism typically stands in contrast with reductionism, which describes systems by dividing them into smaller components in order to understand them through their elemental properties.
A folk taxonomy is a vernacular naming system, as distinct from scientific taxonomy. Folk biological classification is the way people traditionally describe and organize the world around them, typically making generous use of form taxa such as "shrubs", "bugs", "ducks", "fish", "algae", "vegetables", or of economic criteria such as "game animals", "pack animals", "weeds" and other like terms.
The behavioural sciences explore the cognitive processes within organisms and the behavioural interactions between organisms in the natural world. It involves the systematic analysis and investigation of human and animal behaviour through naturalistic observation, controlled scientific experimentation and mathematical modeling. It attempts to accomplish legitimate, objective conclusions through rigorous formulations and observation. Examples of behavioural sciences include psychology, psychobiology, criminology, anthropology, sociology, economics, and cognitive science. Generally, behavioural science primarily seeks to generalise about human behaviour as it relates to society and its impact on society as a whole.
Many scientists and philosophers of science have described evolution as fact and theory, a phrase which was used as the title of an article by paleontologist Stephen Jay Gould in 1981. He describes fact in science as meaning data, not known with absolute certainty but "confirmed to such a degree that it would be perverse to withhold provisional assent". A scientific theory is a well-substantiated explanation of such facts. The facts of evolution come from observational evidence of current processes, from imperfections in organisms recording historical common descent, and from transitions in the fossil record. Theories of evolution provide a provisional explanation for these facts.
The following outline is provided as a topical overview of science; the discipline of science is defined as both the systematic effort of acquiring knowledge through observation, experimentation and reasoning, and the body of knowledge thus acquired, the word "science" derives from the Latin word scientia meaning knowledge. A practitioner of science is called a "scientist". Modern science respects objective logical reasoning, and follows a set of core procedures or rules to determine the nature and underlying natural laws of all things, with a scope encompassing the entire universe. These procedures, or rules, are known as the scientific method.
The theory-theory is a scientific theory relating to the human development of understanding about the outside world. This theory asserts that individuals hold a basic or 'naïve' theory of psychology to infer the mental states of others, such as their beliefs, desires or emotions. This information is used to understand the intentions behind that person's actions or predict future behavior. The term 'perspective taking' is sometimes used to describe how one makes inferences about another person's inner state using theoretical knowledge about the other's situation.
Cognitive anthropology is an approach within cultural anthropology and biological anthropology in which scholars seek to explain patterns of shared knowledge, cultural innovation, and transmission over time and space using the methods and theories of the cognitive sciences often through close collaboration with historians, ethnographers, archaeologists, linguists, musicologists, and other specialists engaged in the description and interpretation of cultural forms. Cognitive anthropology is concerned with what people from different groups know and how that implicit knowledge, in the sense of what they think subconsciously, changes the way people perceive and relate to the world around them.
The branches of science, also referred to as sciences, scientific fields or scientific disciplines, are commonly divided into three major groups:
Evolutionary psychology seeks to identify and understand human psychological traits that have evolved in much the same way as biological traits, through adaptation to environmental cues. Furthermore, it tends toward viewing the vast majority of psychological traits, certainly the most important ones, as the result of past adaptions, which has generated significant controversy and criticism from competing fields. These criticisms include disputes about the testability of evolutionary hypotheses, cognitive assumptions such as massive modularity, vagueness stemming from assumptions about the environment that leads to evolutionary adaptation, the importance of non-genetic and non-adaptive explanations, as well as political and ethical issues in the field itself.
The psychology of reasoning is the study of how people reason, often broadly defined as the process of drawing conclusions to inform how people solve problems and make decisions. It overlaps with psychology, philosophy, linguistics, cognitive science, artificial intelligence, logic, and probability theory.
Causal reasoning is the process of identifying causality: the relationship between a cause and its effect. The study of causality extends from ancient philosophy to contemporary neuropsychology; assumptions about the nature of causality may be shown to be functions of a previous event preceding a later one. The first known protoscientific study of cause and effect occurred in Aristotle's Physics. Causal inference is an example of causal reasoning.
Susan E. Carey is an American psychologist who is a Professor of Psychology at Harvard University. She studies language acquisition, children's development of concepts, conceptual changes over time, and the importance of executive functions. She has conducted experiments on infants, toddlers, adults, and non-human primates. Her books include Conceptual Change in Childhood (1985) and The Origin of Concepts (2009).
Artificial life is a field of study wherein researchers examine systems related to natural life, its processes, and its evolution, through the use of simulations with computer models, robotics, and biochemistry. The discipline was named by Christopher Langton, an American theoretical biologist, in 1986. In 1987, Langton organized the first conference on the field, in Los Alamos, New Mexico. There are three main kinds of alife, named for their approaches: soft, from software; hard, from hardware; and wet, from biochemistry. Artificial life researchers study traditional biology by trying to recreate aspects of biological phenomena.
Intuitive statistics, or folk statistics, is the cognitive phenomenon where organisms use data to make generalizations and predictions about the world. This can be a small amount of sample data or training instances, which in turn contribute to inductive inferences about either population-level properties, future data, or both. Inferences can involve revising hypotheses, or beliefs, in light of probabilistic data that inform and motivate future predictions. The informal tendency for cognitive animals to intuitively generate statistical inferences, when formalized with certain axioms of probability theory, constitutes statistics as an academic discipline.
The illusion of explanatory depth (IOED) is cognitive bias or an illusion where people tend to believe they understand a topic better than they actually do. The term was coined by Yale researchers Leonid Rozenblit and Frank Keil in 2002. The effect was observed in only one type of knowledge called explanatory knowledge, in this case defined as "knowledge that involves complex causal patterns". The effect has not been observed in procedural, narrative, or factual (descriptive) knowledge. Evidence of the IOED occurring has been found in everyday mechanical and electrical devices such as bicycles, in addition to mental disorders, natural phenomena, folk theories, and politics, with the most studied effect of IOED being in politics in the form of political polarization.
