199-479: 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
398-512: A belief in an ideal may involve the belief that this ideal is something good, but it additionally involves a positive evaluative attitude toward this ideal that goes beyond a mere propositional attitude. Applied to the belief in God, opponents of the reductive approach may hold that a belief that God exists may be a necessary pre-condition for belief in God, but that it is not sufficient. The difference between de dicto and de re beliefs or
597-710: A belief in marriage could be translated as a belief that marriage is good. Belief-in is used in a similar sense when expressing self-confidence or faith in one's self or one's abilities. Defenders of a reductive account of belief-in have used this line of thought to argue that belief in God can be analyzed in a similar way: e.g. that it amounts to a belief that God exists with his characteristic attributes, like omniscience and omnipotence . Opponents of this account often concede that belief-in may entail various forms of belief-that, but that there are additional aspects to belief-in that are not reducible to belief-that. For example,
796-447: A crucial experiment . If the experimental results confirm the predictions, then the hypotheses are considered more likely to be correct, but might still be wrong and continue to be subject to further testing. The experimental control is a technique for dealing with observational error. This technique uses the contrast between multiple samples, or observations, or populations, under differing conditions, to see what varies or what remains
995-663: A de re sense, Lois does believe that Clark Kent is strong, while in a de dicto sense she does not. The contexts corresponding to de dicto ascriptions are known as referentially opaque contexts while de re ascriptions are referentially transparent. A collective belief is referred to when people speak of what "we" believe when this is not simply elliptical for what "we all" believe. Sociologist Émile Durkheim wrote of collective beliefs and proposed that they, like all " social facts ", "inhered in" social groups as opposed to individual persons. Jonathan Dancy states that "Durkheim's discussion of collective belief, though suggestive,
1194-400: A dispositive belief ( doxa ) from knowledge ( episteme ) when the opinion is regarded correct (n.b., orthé not alethia ), in terms of right, and juristically so (according to the premises of the dialogue), which was the task of the rhetors to prove. Plato dismisses this possibility of an affirmative relation between opinion and knowledge even when the one who opines grounds his belief on

[REDACTED] Watson and Crick showed an initial (and incorrect) proposal for the structure of DNA to a team from King's College London – Rosalind Franklin , Maurice Wilkins , and Raymond Gosling . Franklin immediately spotted the flaws which concerned the water content. Later Watson saw Franklin's photo 51 ,
1592-523: A belief in a proposition or one does not. This conception is sufficient to understand many belief ascriptions found in everyday language: for example, Pedro's belief that the Earth is bigger than the Moon. But some cases involving comparisons between beliefs are not easily captured through full beliefs alone: for example, that Pedro's belief that the Earth is bigger than the Moon is more certain than his belief that
1791-404: A belief or we don't have a belief") with the more permissive, probabilistic notion of credence ("there is an entire spectrum of degrees of belief, not a simple dichotomy between belief and non-belief"). Beliefs are the subject of various important philosophical debates. Notable examples include: "What is the rational way to revise one's beliefs when presented with various sorts of evidence?", "Is
1990-412: A belief system, and that tenanted belief systems are difficult for the tenants to completely revise or reject. He suggests that beliefs have to be considered holistically , and that no belief exists in isolation in the mind of the believer. Each belief always implicates and relates to other beliefs. Glover provides the example of a patient with an illness who returns to a doctor, but the doctor says that
2189-613: A body of knowledge, method, or practice is scientific. Experimental results should be reproducible and verified by other researchers. These principles are intended to ensure experiments can be reproduced measurably given the same conditions, allowing further investigation to determine whether a hypothesis or theory related to given phenomena is valid and reliable. Standards require the scientific method to be applied throughout, and bias to be controlled for or eliminated through randomization , fair sampling procedures, blinding of studies, and other methods. All gathered data, including

#17327870356552388-410: A book, an advertisement or the testimony of others are the basis of pseudoscience beliefs. It is assumed that illusions are not unusual, and given the right conditions, illusions are able to occur systematically even in normal emotional situations. One of the things pseudoscience believers quibble most about is that academic science usually treats them as fools. Minimizing these illusions in the real world
2587-606: A branch of science, to have been a pseudo-science, composed merely of so-called facts, connected together by misapprehensions under the disguise of principles. An earlier use of the term was in 1843 by the French physiologist François Magendie , that refers to phrenology as " a pseudo-science of the present day ". During the 20th century, the word was used pejoratively to describe explanations of phenomena which were claimed to be scientific, but which were not in fact supported by reliable experimental evidence. From time to time, however,
2786-447: A central role in many religious traditions in which belief in God is one of the central virtues of their followers. The difference between belief-in and belief-that is sometimes blurry since various expressions using the term "belief in" seem to be translatable into corresponding expressions using the term "belief that" instead. For example, a belief in fairies may be said to be a belief that fairies exist. In this sense, belief-in
2985-476: A century of study by philosophers of science and scientists , and despite some basic agreements on the fundamentals of the scientific method. The concept of pseudoscience rests on an understanding that the scientific method has been misrepresented or misapplied with respect to a given theory, but many philosophers of science maintain that different kinds of methods are held as appropriate across different fields and different eras of human history. According to Lakatos,
3184-461: A certain way is called a belief. This is not just true for humans but may include animals, hypothetical aliens or even computers. From this perspective, it would make sense to ascribe the belief that a traffic light is red to a self-driving car behaving just like a human driver. Dispositionalism is sometimes seen as a specific form of functionalism. It defines beliefs only concerning their role as causes of behavior or as dispositions to behave in
3383-446: A certain way. For example, a belief that there is a pie in the pantry is associated with the disposition to affirm this when asked and to go to the pantry when hungry. While it is uncontroversial that beliefs shape our behavior, the thesis that beliefs can be defined exclusively through their role in producing behavior has been contested. The problem arises because the mechanisms shaping our behavior seem to be too complex to single out
3582-444: A chess computer will behave. The entity has the belief in question if this belief can be used to predict its behavior. Having a belief is relative to an interpretation since there may be different equally good ways of ascribing beliefs to predict behavior. So there may be another interpretation that predicts the move of the queen to f7 that does not involve the belief that this move will win the game. Another version of interpretationism
3781-518: A controlled setting, such as a laboratory, or made on more or less inaccessible or unmanipulatable objects such as stars or human populations. The measurements often require specialized scientific instruments such as thermometers , spectroscopes , particle accelerators , or voltmeters , and the progress of a scientific field is usually intimately tied to their invention and improvement. I am not accustomed to saying anything with certainty after only one or two observations. The scientific definition of
3980-411: A detailed X-ray diffraction image, which showed an X-shape and was able to confirm the structure was helical. Once predictions are made, they can be sought by experiments. If the test results contradict the predictions, the hypotheses which entailed them are called into question and become less tenable. Sometimes the experiments are conducted incorrectly or are not very well designed when compared to
4179-421: A different set of rules compared to rational thinking, experiential thinking regards an explanation as valid if the explanation is "personally functional, satisfying and sufficient", offering a description of the world that may be more personal than can be provided by science and reducing the amount of potential work involved in understanding complex events and outcomes. Anyone searching for psychological help that

This stage frequently involves finding and evaluating evidence from previous experiments, personal scientific observations or assertions, as well as the work of other scientists. If the answer is already known, a different question that builds on the evidence can be posed. When applying the scientific method to research, determining a good question can be very difficult and it will affect
4577-409: A few closely related beliefs while holists hold that they may obtain between any two beliefs, however unrelated they seem. For example, assume that Mei and Benjamin both affirm that Jupiter is a planet. The most straightforward explanation, given by the atomists, would be that they have the same belief, i.e. that they hold the same content to be true. But now assume that Mei also believes that Pluto
4776-472: A forward-minded species pursuing greater avenues of happiness and satisfaction, but we are all too frequently willing to grasp at unrealistic promises of a better life. Psychology has much to discuss about pseudoscience thinking, as it is the illusory perceptions of causality and effectiveness of numerous individuals that needs to be illuminated. Research suggests that illusionary thinking happens in most people when exposed to certain circumstances such as reading
4975-399: A given field can be tested experimentally and standards are upheld, it is not pseudoscience, regardless of how odd, astonishing, or counterintuitive those claims are. If claims made are inconsistent with existing experimental results or established theory, but the method is sound, caution should be used, since science consists of testing hypotheses which may turn out to be false. In such a case,
5174-431: A guideline for proceeding: The iterative cycle inherent in this step-by-step method goes from point 3 to 6 and back to 3 again. While this schema outlines a typical hypothesis/testing method, many philosophers, historians, and sociologists of science, including Paul Feyerabend , claim that such descriptions of scientific method have little relation to the ways that science is actually practiced. The basic elements of
5373-452: A language-like structure, sometimes referred to as "mentalese". Just like regular language, this involves simple elements that are combined in various ways according to syntactic rules to form more complex elements that act as bearers of meaning. On this conception, holding a belief would involve storing such a complex element in one's mind. Different beliefs are separated from each other in that they correspond to different elements stored in
5572-485: A man who pushes a child into the water with the intention of drowning it; and that of a man who sacrifices his life in an attempt to save the child." From Freud's perspective, the first man would have suffered from psychological repression , probably originating from an Oedipus complex , whereas the second man had attained sublimation . From Adler's perspective, the first and second man suffered from feelings of inferiority and had to prove himself, which drove him to commit
5771-402: A mental attitude towards the proposition "It will be sunny today" which affirms that this proposition is true. This is different from Sofía's desire that it will be sunny today, despite the fact that both Rahul and Sofía have attitudes toward the same proposition. The mind-to-world direction of fit of beliefs is sometimes expressed by saying that beliefs aim at truth. This aim is also reflected in
5970-578: A meta-bias called the bias blind spot , or the tendency to recognize the power of cognitive biases in other people but to be blind to their influence on our own beliefs". Lindeman states that social motives (i.e., "to comprehend self and the world, to have a sense of control over outcomes, to belong, to find the world benevolent and to maintain one's self-esteem") are often "more easily" fulfilled by pseudoscience than by scientific information. Furthermore, pseudoscientific explanations are generally not analyzed rationally, but instead experientially. Operating within
6169-404: A more realistic sense: that entities really have the beliefs ascribed to them and that these beliefs participate in the causal network. But, for this to be possible, it may be necessary to define interpretationism as a methodology and not as an ontological outlook on beliefs. Biologist Lewis Wolpert discusses the importance of causal beliefs and associates the making and use of tools with

6368-661: A particular culture. People with syncretic views blend the views of a variety of different religions or traditional beliefs into a unique fusion which suits their particular experiences and contexts ( eclecticism ). Unitarian Universalism exemplifies a syncretic faith. Typical reasons for adherence to religion include the following: Psychologist James Alcock also summarizes a number of apparent benefits which reinforce religious belief. These include prayer appearing to account for successful resolution of problems, "a bulwark against existential anxiety and fear of annihilation," an increased sense of control, companionship with one's deity,
6567-400: A particular function ( Hilary Putnam ). Some have also attempted to offer significant revisions to our notion of belief, including eliminativists about belief who argue that there is no phenomenon in the natural world which corresponds to our folk psychological concept of belief ( Paul Churchland ) and formal epistemologists who aim to replace our bivalent notion of belief ("either we have
6766-403: A phenomenon under study. Albert Einstein once observed that "there is no logical bridge between phenomena and their theoretical principles." Charles Sanders Peirce , borrowing a page from Aristotle ( Prior Analytics , 2.25 ) described the incipient stages of inquiry , instigated by the "irritation of doubt" to venture a plausible guess, as abductive reasoning . The history of science

These institutions thereby reduce the research function to a cost/benefit, which is expressed as money, and the time and attention of the researchers to be expended, in exchange for a report to their constituents. Current large instruments, such as CERN's Large Hadron Collider (LHC), or LIGO , or

In general, scientists tend to look for theories that are " elegant " or " beautiful ". Scientists often use these terms to refer to a theory that is following the known facts but is nevertheless relatively simple and easy to handle. Occam's Razor serves as
7363-436: A programme could evolve, driven by its heuristic to make predictions that can be supported by evidence. Feyerabend claimed that Lakatos was selective in his examples, and the whole history of science shows there is no universal rule of scientific method, and imposing one on the scientific community impedes progress. Laudan maintained that the demarcation between science and non-science was a pseudo-problem, preferring to focus on
7562-519: A rule of thumb for choosing the most desirable amongst a group of equally explanatory hypotheses. To minimize the confirmation bias that results from entertaining a single hypothesis, strong inference emphasizes the need for entertaining multiple alternative hypotheses, and avoiding artifacts. [REDACTED] James D. Watson , Francis Crick , and others hypothesized that DNA had a helical structure. This implied that DNA's X-ray diffraction pattern would be 'x shaped'. This prediction followed from
7761-452: A scientific field. Karl Popper stated it is insufficient to distinguish science from pseudoscience, or from metaphysics (such as the philosophical question of what existence means), by the criterion of rigorous adherence to the empirical method , which is essentially inductive, based on observation or experimentation. He proposed a method to distinguish between genuine empirical, nonempirical or even pseudoempirical methods. The latter case
7960-429: A sentence and in a map through its internal geometrical relations. Functionalism contrasts with representationalism in that it defines beliefs not in terms of the internal constitution of the mind but in terms of the function or the causal role played by them. This view is often combined with the idea that the same belief can be realized in various ways and that it does not matter how it is realized as long as it plays
8159-619: A set of phenomena. Normally, hypotheses have the form of a mathematical model . Sometimes, but not always, they can also be formulated as existential statements , stating that some particular instance of the phenomenon being studied has some characteristic and causal explanations, which have the general form of universal statements , stating that every instance of the phenomenon has a particular characteristic. Scientists are free to use whatever resources they have – their own creativity, ideas from other fields, inductive reasoning , Bayesian inference , and so on – to imagine possible explanations for

8358-402: A source of self-significance, and group identity. Typical reasons for rejection of religion include: Mainstream psychology and related disciplines have traditionally treated belief as if it were the simplest form of mental representation and therefore one of the building blocks of conscious thought. Philosophers have tended to be more abstract in their analysis, and much of the work examining
8557-450: A special class of mental representations since they do not involve sensory qualities in order to represent something, unlike perceptions or episodic memories. Because of this, it seems natural to construe beliefs as attitudes towards propositions, which also constitute non-sensory representations, i.e. as propositional attitudes . As mental attitudes , beliefs are characterized by both their content and their mode. The content of an attitude
8756-823: A specific element of proselytization . This is a strongly-held belief in the Christian tradition which follows the doctrine of the Great Commission , and is less emphasized by the Islamic faith where the Quranic edict "There shall be no compulsion in religion" (2:256) is often quoted as a justification for toleration of alternative beliefs. The Jewish tradition does not actively seek out converts. Exclusivism correlates with conservative, fundamentalist, and orthodox approaches of many religions, while pluralistic and syncretist approaches either explicitly downplay or reject
8955-421: A statement may be pseudoscientific even if it is eminently 'plausible' and everybody believes in it, and it may be scientifically valuable even if it is unbelievable and nobody believes in it. A theory may even be of supreme scientific value even if no one understands it, let alone believes in it. The boundary between science and pseudoscience is disputed and difficult to determine analytically, even after more than
9154-584: A term sometimes differs substantially from its natural language usage. For example, mass and weight overlap in meaning in common discourse, but have distinct meanings in mechanics . Scientific quantities are often characterized by their units of measure which can later be described in terms of conventional physical units when communicating the work. New theories are sometimes developed after realizing certain terms have not previously been sufficiently clearly defined. For example, Albert Einstein 's first paper on relativity begins by defining simultaneity and

In Russia, in the late 20th and early 21st century, significant budgetary funds were spent on programs for the experimental study of " torsion fields ", the extraction of energy from granite, the study of " cold nuclear fusion ", and astrological and extrasensory "research" by the Ministry of Defense , the Ministry of Emergency Situations ,

This is the case despite the fact that the two readers have

The majority of his works include the topics of Atlantis , extraterrestrial encounters, and Lemuria as well as other ancient civilizations, often with white supremacist undertones. For example, he posited that European peoples migrated to North America before Columbus , and that all Native American civilizations were initiated by descendants of white people . The Alt-Right using pseudoscience to base their ideologies on

Religious belief is distinct from religious practice and from religious behaviours —with some believers not practicing religion and some practitioners not believing religion.

This indicates that they have different concepts of planet , which would mean that they were affirming different contents when they both agreed that Jupiter is a planet. This reasoning leads to molecularism or holism because the content of the Jupiter-belief depends on the Pluto-belief in this example. An important motivation for this position comes from W. V. Quine 's confirmational holism , which holds that, because of this interconnectedness, we cannot confirm or disconfirm individual hypotheses, that confirmation happens on

The scientific method involves careful observation coupled with rigorous scepticism , because cognitive assumptions can distort the interpretation of the observation . Scientific inquiry includes creating a testable hypothesis through inductive reasoning , testing it through experiments and statistical analysis, and adjusting or discarding

Hupp and Santa Maria provide a complete explanation of what that person should look for. There is a trend to believe in pseudoscience more than scientific evidence . Some people believe the prevalence of pseudoscientific beliefs is due to widespread scientific illiteracy . Individuals lacking scientific literacy are more susceptible to wishful thinking, since they are likely to turn to immediate gratification powered by System 1, our default operating system which requires little to no effort. This system encourages one to accept

It states that partial beliefs are basic and that full beliefs are to be conceived as partial beliefs above a certain threshold: for example, every belief above 0.9 is a full belief. Defenders of a primitive notion of full belief, on the other hand, have tried to explain partial beliefs as full beliefs about probabilities. On this view, having a partial belief of degree 0.9 that it will rain tomorrow

The primary problem in epistemology is to understand what is needed to have knowledge. In a notion derived from Plato 's dialogue Theaetetus , where the epistemology of Socrates most clearly departs from that of the sophists , who appear to have defined knowledge as " justified true belief ". The tendency to base knowledge ( episteme ) on common opinion ( doxa ) Socrates dismisses, results from failing to distinguish
11144-418: Is driven by the belief that the brain is essentially a "belief engine" which scans data perceived by the senses and looks for patterns and meaning. There is also the tendency for the brain to create cognitive biases , as a result of inferences and assumptions made without logic and based on instinct – usually resulting in patterns in cognition. These tendencies of patternicity and agenticity are also driven "by
11343-845: Is due to Donald Davidson , who uses the thought experiment of radical interpretation , in which the goal is to make sense of the behavior and language of another person from scratch without any knowledge of this person's language. This process involves ascribing beliefs and desires to the speaker. The speaker really has these beliefs if this project can be successful in principle. Interpretationism can be combined with eliminativism and instrumentalism about beliefs. Eliminativists hold that, strictly speaking, there are no beliefs. Instrumentalists agree with eliminativists but add that belief-ascriptions are useful nonetheless. This usefulness can be explained in terms of interpretationism: belief-ascriptions help us in predicting how entities will behave. It has been argued that interpretationism can also be understood in
11542-399: Is essential that the outcome of testing such a prediction be currently unknown. Only in this case does a successful outcome increase the probability that the hypothesis is true. If the outcome is already known, it is called a consequence and should have already been considered while formulating the hypothesis . If the predictions are not accessible by observation or experience, the hypothesis

Externalism, on the other hand, holds that the relations to one's environment also have a role to play in this.

Atomists deny such dependence relations, molecularists restrict them to only

Other groups, too, are painted similarly in 'race science', as it used to call itself: African-Americans,

Therefore, science itself can have little to say about the possibility. In

Therefore, practitioners and advocates of pseudoscience frequently dispute the characterization. The word pseudoscience is derived from the Greek root pseudo meaning "false" and the English word science , from the Latin word scientia , meaning "knowledge". Although

Typical examples would include: "he believes in witches and ghosts" or "many children believe in Santa Claus " or "I believe in a deity". Not all usages of belief-in concern the existence of something: some are commendatory in that they express a positive attitude towards their object. It has been suggested that these cases can also be accounted for in terms of belief-that. For example,

For example, pseudoscientific anti-vaccine activism and promotion of homeopathic remedies as alternative disease treatments can result in people forgoing important medical treatments with demonstrable health benefits, leading to ill-health and deaths. Furthermore, people who refuse legitimate medical treatments for contagious diseases may put others at risk. Pseudoscientific theories about racial and ethnic classifications have led to racism and genocide . The term pseudoscience
13731-412: Is relatively obscure". Margaret Gilbert has offered a related account in terms of the joint commitment of a number of persons as a body to accept a certain belief. According to this account, individuals who together collectively believe something need not personally believe it individually. Gilbert's work on the topic has stimulated a developing literature among philosophers. One question that has arisen
13930-692: Is subset of non-science. Science is also distinguishable from revelation, theology, or spirituality in that it offers insight into the physical world obtained by empirical research and testing. The most notable disputes concern the evolution of living organisms, the idea of common descent, the geologic history of the Earth, the formation of the Solar System , and the origin of the universe. Systems of belief that derive from divine or inspired knowledge are not considered pseudoscience if they do not claim either to be scientific or to overturn well-established science. Moreover, some specific religious claims, such as

So no degree of commitment to beliefs makes them knowledge. Indeed, the hallmark of scientific behaviour is a certain scepticism even towards one's most cherished theories. Blind commitment to a theory is not an intellectual virtue: it is an intellectual crime. Thus
14328-461: Is the process by which science is carried out. As in other areas of inquiry, science (through the scientific method) can build on previous knowledge, and unify understanding of its studied topics over time. This model can be seen to underlie the scientific revolution . The overall process involves making conjectures ( hypotheses ), predicting their logical consequences, then carrying out experiments based on those predictions to determine whether
14527-454: Is the same as having a full belief that the probability of rain tomorrow is 90%. Another approach circumvents the notion of probability altogether and replaces degrees of belief with degrees of disposition to revise one's full belief. From this perspective, both a belief of degree 0.6 and a belief of degree 0.9 may be seen as full beliefs. The difference between them is that the former belief can readily be changed upon receiving new evidence while

Distinguishing between proper science and pseudoscience is sometimes difficult. One proposal for demarcation between the two is the falsification criterion, attributed most notably to the philosopher Karl Popper . In

Functionalists use such characteristics to define beliefs: whatever is caused by perceptions in a certain way and also causes behavior in

However, holding a belief does not require active introspection . For example, few individuals carefully consider whether or not the sun will rise tomorrow, simply assuming that it will. Moreover, beliefs need not be occurrent (e.g. a person actively thinking "snow

Taking a historical approach, Kuhn observed that scientists did not follow Popper's rule, and might ignore falsifying data, unless overwhelming. To Kuhn, puzzle-solving within a paradigm is science.

Beliefs are usually distinguished from other propositional attitudes, like desires, by their mode or the way in which they are directed at propositions. The mode of beliefs has a mind-to-world direction of fit : beliefs try to represent the world as it is; they do not, unlike desires, involve an intention to change it. For example, if Rahul believes that it will be sunny today, then he has
15920-456: Is whether and how philosophical accounts of belief in general need to be sensitive to the possibility of collective belief. Collective belief can play a role in social control and serve as a touchstone for identifying and purging heresies , deviancy or political deviationism . As mental representations , beliefs have contents, which is what the belief is about or what it represents. Within philosophy, there are various disputes about how
16119-508: Is white"), but can instead be dispositional (e.g. a person who if asked about the color of snow would assert "snow is white"). There are various ways that contemporary philosophers have tried to describe beliefs, including as representations of ways that the world could be ( Jerry Fodor ), as dispositions to act as if certain things are true ( Roderick Chisholm ), as interpretive schemes for making sense of someone's actions ( Daniel Dennett and Donald Davidson ), or as mental states that fill
16318-515: Is your evidence?" For philosophers Silvio Funtowicz and Jerome R. Ravetz "pseudo-science may be defined as one where the uncertainty of its inputs must be suppressed, lest they render its outputs totally indeterminate". The definition, in the book Uncertainty and Quality in Science for Policy , alludes to the loss of craft skills in handling quantitative information, and to the bad practice of achieving precision in prediction (inference) only at
16517-647: The Catholic Church each consider themselves to be the true heir to Early Christian belief and practice. The antonym of "orthodox" is " heterodox ", and those adhering to orthodoxy often accuse the heterodox of apostasy , schism , or heresy . The Renaissance and later the Enlightenment in Europe exhibited varying degrees of religious tolerance and intolerance towards new and old religious ideas. The philosophes took particular exception to many of
16716-518: The Grand Canyon is in Arizona involves entertaining the representation associated with this belief—for example, by actively thinking about it. But the great majority of our beliefs are not active most of the time: they are merely dispositional. They usually become activated or occurrent when needed or relevant in some way and then fall back into their dispositional state afterwards. For example,
16915-614: The Immigration Act of 1924 in the United States, which sought to prevent immigration from Asia and parts of Europe. In a 1981 report Singer and Benassi wrote that pseudoscientific beliefs have their origin from at least four sources. A 1990 study by Eve and Dunn supported the findings of Singer and Benassi and found pseudoscientific belief being promoted by high school life science and biology teachers. The psychology of pseudoscience attempts to explore and analyze pseudoscientific thinking by means of thorough clarification on making
17114-742: The Ministry of Internal Affairs , and the State Duma (see Military Unit 10003 ). In 2006, Deputy Chairman of the Security Council of the Russian Federation Nikolai Spassky published an article in Rossiyskaya Gazeta , where among the priority areas for the development of the Russian energy sector , the task of extracting energy from a vacuum was in the first place. The Clean Water project
17313-717: The National Ignition Facility (NIF), or the International Space Station (ISS), or the James Webb Space Telescope (JWST), entail expected costs of billions of dollars, and timeframes extending over decades. These kinds of institutions affect public policy, on a national or even international basis, and the researchers would require shared access to such machines and their adjunct infrastructure . Scientists assume an attitude of openness and accountability on
17512-655: The Roman Catholic Church ) still hold to exclusivist dogma while participating in inter-religious organizations. Explicitly inclusivist religions include many that are associated with the New Age movement, as well as modern reinterpretations of Hinduism and Buddhism . The Baháʼí Faith considers it doctrine that there is truth in all faith-systems. Pluralism and syncretism are two closely related concepts. People with pluralist beliefs make no distinction between faith systems, viewing each one as valid within
17711-452: The founders or leaders , and considers it a matter of faith that the "correct" religion has a monopoly on truth. All three major Abrahamic monotheistic religions have passages in their holy scriptures that attest to the primacy of the scriptural testimony, and indeed monotheism itself is often vouched as an innovation characterized specifically by its explicit rejection of earlier polytheistic faiths. Some exclusivist faiths incorporate
17910-486: The history of science and the history of pseudoscience it can be especially difficult to separate the two, because some sciences developed from pseudosciences. An example of this transformation is the science of chemistry , which traces its origins to the pseudoscientific or pre-scientific study of alchemy . The vast diversity in pseudosciences further complicates the history of science. Some modern pseudosciences, such as astrology and acupuncture , originated before
18109-441: The humanities . Dividing the category again, unscientific claims are a subset of the large category of non-scientific claims. This category specifically includes all matters that are directly opposed to good science. Un-science includes both "bad science" (such as an error made in a good-faith attempt at learning something about the natural world) and pseudoscience. Thus pseudoscience is a subset of un-science, and un-science, in turn,
18308-676: The precession of equinoxes in astronomy. Third, alternative theories of personality and behavior have grown progressively to encompass explanations of phenomena which astrology statically attributes to heavenly forces. Fourth, astrologers have remained uninterested in furthering the theory to deal with outstanding problems or in critically evaluating the theory in relation to other theories. Thagard intended this criterion to be extended to areas other than astrology. He believed it would delineate as pseudoscientific such practices as witchcraft and pyramidology , while leaving physics , chemistry , astronomy , geoscience , biology , and archaeology in
18507-474: The scientific revolution of the 16th and 17th centuries some of the most important developments were the furthering of empiricism by Francis Bacon and Robert Hooke , the rationalist approach described by René Descartes and inductivism , brought to particular prominence by Isaac Newton and those who followed him. Experiments were advocated by Francis Bacon , and performed by Giambattista della Porta , Johannes Kepler , and Galileo Galilei . There
18706-415: The visual system , rather than to study free will , for example. His cautionary example was the gene; the gene was much more poorly understood before Watson and Crick's pioneering discovery of the structure of DNA; it would have been counterproductive to spend much time on the definition of the gene, before them. [REDACTED] Linus Pauling proposed that DNA might be a triple helix . This hypothesis
18905-522: The "justified true belief" definition. Justified true belief is a definition of knowledge that gained approval during the Enlightenment , "justified" standing in contrast to "revealed". There have been attempts to trace it back to Plato and his dialogues, more specifically in the Theaetetus , and the Meno . The concept of justified true belief states that in order to know that a given proposition
19104-446: The "physical stance" and the "design stance". These stances are contrasted with the intentional stance , which is applied to entities with a more complex behavior by ascribing beliefs and desires to these entities. For example, we can predict that a chess player will move her queen to f7 if we ascribe to her the desire to win the game and the belief that this move will achieve that. The same procedure can also be applied to predicting how
19303-589: The "scientific method" and in doing so largely replaced the notion of science as a homogeneous and universal method with that of it being a heterogeneous and local practice. In particular, Paul Feyerabend, in the 1975 first edition of his book Against Method , argued against there being any universal rules of science ; Karl Popper , and Gauch 2003, disagree with Feyerabend's claim. Later stances include physicist Lee Smolin 's 2013 essay "There Is No Scientific Method", in which he espouses two ethical principles , and historian of science Daniel Thurs' chapter in
19502-519: The 10 commonly believed examples of paranormal phenomena listed in the poll were "pseudoscientific beliefs". The items were "extrasensory perception (ESP), that houses can be haunted , ghosts , telepathy , clairvoyance , astrology, that people can mentally communicate with the dead , witches , reincarnation , and channelling ". Such beliefs in pseudoscience represent a lack of knowledge of how science works. The scientific community may attempt to communicate information about science out of concern for
19701-449: The 1830s and 1850s, when Baconianism was popular, naturalists like William Whewell, John Herschel and John Stuart Mill engaged in debates over "induction" and "facts" and were focused on how to generate knowledge. In the late 19th and early 20th centuries, a debate over realism vs. antirealism was conducted as powerful scientific theories extended beyond the realm of the observable. The term "scientific method" came into popular use in
19900-425: The 2015 book Newton's Apple and Other Myths about Science , which concluded that the scientific method is a myth or, at best, an idealization. As myths are beliefs, they are subject to the narrative fallacy as Taleb points out. Philosophers Robert Nola and Howard Sankey, in their 2007 book Theories of Scientific Method , said that debates over the scientific method continue, and argued that Feyerabend, despite
20099-441: The Earth is bigger than Venus. Such cases are most naturally analyzed in terms of partial beliefs involving degrees of belief, so-called credences . The higher the degree of a belief, the more certain the believer is that the believed proposition is true. This is usually formalized by numbers between 0 and 1: a degree of 1 represents an absolutely certain belief, a belief of 0 corresponds to an absolutely certain disbelief and all
20298-494: The Earth, while controlled experiments can be seen in the works of al-Battani (853–929 CE) and Alhazen (965–1039 CE). [REDACTED] Watson and Crick then produced their model, using this information along with the previously known information about DNA's composition, especially Chargaff's rules of base pairing. After considerable fruitless experimentation, being discouraged by their superior from continuing, and numerous false starts, Watson and Crick were able to infer
20497-588: The Irish, the Chinese and, well, any and all groups that you want to prove inferior to yourself". Neo-Nazis and white supremacist often try to support their claims with studies that "prove" that their claims are more than just harmful stereotypes. For example Bret Stephens published a column in The New York Times where he claimed that Ashkenazi Jews had the highest IQ among any ethnic group. However,
20696-609: The Sun), precisely as material bodies were attracted." Following from this, stars closer to the Sun would appear to have moved a small distance away from the Sun, and away from each other. This prediction was particularly striking to Popper because it involved considerable risk. The brightness of the Sun prevented this effect from being observed under normal circumstances, so photographs had to be taken during an eclipse and compared to photographs taken at night. Popper states, "If observation shows that
20895-459: The United States population lacks scientific literacy, not adequately understanding scientific principles and method . In the Journal of College Science Teaching , Art Hobson writes, "Pseudoscientific beliefs are surprisingly widespread in our culture even among public school science teachers and newspaper editors, and are closely related to scientific illiteracy." However, a 10,000-student study in
21094-414: The above conditions were seemingly met but where many philosophers deny that anything is known. Robert Nozick suggested a clarification of "justification" which he believed eliminates the problem: the justification has to be such that were the justification false, the knowledge would be false. Bernecker and Dretske (2000) argue that "no epistemologist since Gettier has seriously and successfully defended
21293-533: The attitude. This view contrasts with functionalism , which defines beliefs not in terms of the internal constitution of the mind but in terms of the function or the causal role played by beliefs. According to dispositionalism , beliefs are identified with dispositions to behave in certain ways. This view can be seen as a form of functionalism, defining beliefs in terms of the behavior they tend to cause. Interpretationism constitutes another conception, which has gained popularity in contemporary philosophy. It holds that
21492-446: The basic method used for scientific inquiry. The scientific community and philosophers of science generally agree on the following classification of method components. These methodological elements and organization of procedures tend to be more characteristic of experimental sciences than social sciences . Nonetheless, the cycle of formulating hypotheses, testing and analyzing the results, and formulating new hypotheses, will resemble
21691-417: The belief that 57 is greater than 14 was probably dispositional to the reader before reading this sentence, has become occurrent while reading it and may soon become dispositional again as the mind focuses elsewhere. The distinction between occurrent and dispositional beliefs is sometimes identified with the distinction between conscious and unconscious beliefs. But it has been argued that, despite overlapping,
21890-545: The beliefs of an entity are in some sense dependent on or relative to someone's interpretation of this entity. Representationalism tends to be associated with mind-body-dualism. Naturalist considerations against this dualism are among the motivations for choosing one of the alternative conceptions. Representationalism characterizes beliefs in terms of mental representations . Representations are usually defined as objects with semantic properties —like having content, referring to something, or being true or false. Beliefs form
22089-421: The beliefs of an entity are in some sense dependent on, or relative to, someone's interpretation of this entity. Daniel Dennett is an important defender of such a position. He holds that we ascribe beliefs to entities in order to predict how they will behave. Entities with simple behavioral patterns can be described using physical laws or in terms of their function. Dennett refers to these forms of explanation as
22288-420: The causal role characteristic to it. As an analogy, a hard drive is defined in a functionalist manner: it performs the function of storing and retrieving digital data. This function can be realized in many different ways: being made of plastic or steel, or using magnetism or laser. Functionalists hold that something similar is true for beliefs (or mental states in general). Among the roles relevant to beliefs
22487-452: The conclusions they believe , and reject the ones they do not. Further analysis of complex pseudoscientific phenomena require System 2, which follows rules, compares objects along multiple dimensions and weighs options. These two systems have several other differences which are further discussed in the dual-process theory . The scientific and secular systems of morality and meaning are generally unsatisfying to most people. Humans are, by nature,
22686-453: The content of our beliefs entirely determined by our mental states, or do the relevant facts have any bearing on our beliefs (e.g. if I believe that I'm holding a glass of water, is the non-mental fact that water is H 2 O part of the content of that belief)?", "How fine-grained or coarse-grained are our beliefs?", and "Must it be possible for a belief to be expressible in language, or are there non-linguistic beliefs?" Various conceptions of
22885-411: The contents of beliefs are to be understood. Holists and molecularists hold that the content of one particular belief depends on or is determined by other beliefs belonging to the same subject, which is denied by atomists. The question of dependence or determination also plays a central role in the internalism-externalism- debate. Internalism states that the contents of someone's beliefs depend only on what
23084-544: The context of Early Christianity , the term "orthodoxy" relates to religious belief that closely follows the edicts, apologies , and hermeneutics of a prevailing religious authority. In the case of Early Christianity, this authority was the communion of bishops, and is often referred to by the term " Magisterium ". The term orthodox was applied almost as an epithet to a group of Jewish believers who held to pre-Enlightenment understanding of Judaism—now known as Orthodox Judaism . The Eastern Orthodox Church of Christianity and
23283-467: The contrary, if the astronomically massive, the feather-light, and the extremely fast are removed from Einstein's theories – all phenomena Newton could not have observed – Newton's equations are what remain. Einstein's theories are expansions and refinements of Newton's theories and, thus, increase confidence in Newton's work. An iterative, pragmatic scheme of the four points above is sometimes offered as
23482-410: The corresponding ascriptions concerns the contributions singular terms like names and other referential devices make to the semantic properties of the belief or its ascription. In regular contexts, the truth-value of a sentence does not change upon substitution of co-referring terms. For example, since the names "Superman" and "Clark Kent" refer to the same person, we can replace one with the other in
23681-505: The crime or, in the second case, drove him to rescue the child. Popper was not able to find any counterexamples of human behavior in which the behavior could not be explained in the terms of Adler's or Freud's theory. Popper argued it was that the observation always fitted or confirmed the theory which, rather than being its strength, was actually its weakness. In contrast, Popper gave the example of Einstein's gravitational theory , which predicted "light must be attracted by heavy bodies (such as
23880-617: The criterion of falsifiability to distinguish science from non-science . Statements , hypotheses , or theories have falsifiability or refutability if there is the inherent possibility that they can be proven false , that is, if it is possible to conceive of an observation or an argument that negates them. Popper used astrology and psychoanalysis as examples of pseudoscience and Einstein's theory of relativity as an example of science. He subdivided non-science into philosophical, mathematical, mythological, religious and metaphysical formulations on one hand, and pseudoscientific formulations on
24079-553: The cycle described below. The scientific method is an iterative, cyclical process through which information is continually revised. It is generally recognized to develop advances in knowledge through the following elements, in varying combinations or contributions: Each element of the scientific method is subject to peer review for possible mistakes. These activities do not describe all that scientists do but apply mostly to experimental sciences (e.g., physics, chemistry, biology, and psychology). The elements above are often taught in
24278-416: The differing doctrines and practices espoused by other religions or by other religious denominations in a variety of ways. People with exclusivist beliefs typically explain other beliefs either as in error, or as corruptions or counterfeits of the true faith . This approach is a fairly consistent feature among smaller new religious movements that often rely on doctrine that claims a unique revelation by
24477-502: The distinction of what is considered scientific vs. pseudoscientific. The human proclivity for seeking confirmation rather than refutation ( confirmation bias ), the tendency to hold comforting beliefs, and the tendency to overgeneralize have been proposed as reasons for pseudoscientific thinking. According to Beyerstein, humans are prone to associations based on resemblances only, and often prone to misattribution in cause-effect thinking. Michael Shermer 's theory of belief-dependent realism
24676-557: The educational system as "the scientific method". The scientific method is not a single recipe: it requires intelligence, imagination, and creativity. In this sense, it is not a mindless set of standards and procedures to follow but is rather an ongoing cycle , constantly developing more useful, accurate, and comprehensive models and methods. For example, when Einstein developed the Special and General Theories of Relativity, he did not in any way refute or discount Newton's Principia . On
24875-415: The essential features of beliefs have been proposed, but there is no consensus as to which is the right one. Representationalism is the traditionally dominant position. Its most popular version maintains that attitudes toward representations, which are typically associated with propositions, are mental attitudes that constitute beliefs. These attitudes are part of the internal constitution of the mind holding
25074-402: The essential structure of DNA by concrete modeling of the physical shapes of the nucleotides which comprise it. They were guided by the bond lengths which had been deduced by Linus Pauling and by Rosalind Franklin 's X-ray diffraction images. The scientific method is iterative. At any stage, it is possible to refine its accuracy and precision , so that some consideration will lead
25273-493: The exclusivist tendencies within a religion. People with inclusivist beliefs recognize some truth in all faith systems , highlighting agreements and minimizing differences. This attitude is sometimes associated with Interfaith dialogue or with the Christian Ecumenical movement, though in principle such attempts at pluralism are not necessarily inclusivist and many actors in such interactions (for example,
25472-528: The existence, characteristics and worship of a deity or deities, to the idea of divine intervention in the universe and in human life , or to the deontological explanations for the values and practices centered on the teachings of a spiritual leader or community . In contrast to other belief systems , religious beliefs are usually codified . A popular view holds that different religions each have identifiable and exclusive sets of beliefs or creeds , but surveys of religious belief have often found that
25671-421: The expenses of ignoring uncertainty in the input which was used to formulate the prediction. This use of the term is common among practitioners of post-normal science . Understood in this way, pseudoscience can be fought using good practices to assess uncertainty in quantitative information, such as NUSAP and – in the case of mathematical modelling – sensitivity auditing . The history of pseudoscience
25870-448: The experimental method, the hypothesis, or the definition of the subject. This manner of iteration can span decades and sometimes centuries. Published papers can be built upon. For example: By 1027, Alhazen , based on his measurements of the refraction of light, was able to deduce that outer space was less dense than air , that is: "the body of the heavens is rarer than the body of air". In 1079 Ibn Mu'adh 's Treatise On Twilight
26069-409: The experimental or environmental conditions, are expected to be documented for scrutiny and made available for peer review , allowing further experiments or studies to be conducted to confirm or falsify results. Statistical quantification of significance , confidence , and error are also important tools for the scientific method. During the mid-20th century, the philosopher Karl Popper emphasized
26268-458: The following terms: a statement constitutes knowledge if sufficiently many people believe it sufficiently strongly. But the history of thought shows us that many people were totally committed to absurd beliefs. If the strengths of beliefs were a hallmark of knowledge, we should have to rank some tales about demons, angels, devils, and of heaven and hell as knowledge. Scientists, on the other hand, are very sceptical even of their best theories. Newton's
26467-416: The force of Kuhn's historical criticism of Popper – all important theories have been surrounded by an 'ocean of anomalies', which on a falsificationist view would require the rejection of the theory outright...Lakatos sought to reconcile the rationalism of Popperian falsificationism with what seemed to be its own refutation by history". Many philosophers have tried to solve the problem of demarcation in
26666-468: The future, a new technique may allow for an experimental test and the speculation would then become part of accepted science. For example, Einstein's theory of general relativity makes several specific predictions about the observable structure of spacetime , such as that light bends in a gravitational field , and that the amount of bending depends in a precise way on the strength of that gravitational field. Arthur Eddington 's observations made during
26865-495: The general contribution of one particular belief for any possible situation. For example, one may decide not to affirm that there is a pie in the pantry when asked because one wants to keep it secret. Or one might not eat the pie despite being hungry, because one also believes that it is poisoned. Due to this complexity, we are unable to define even a belief as simple as this one in terms of the behavioral dispositions for which it could be responsible. According to interpretationism,
27064-442: The hypothesis based on the results. Although procedures vary between fields , the underlying process is often similar. In more detail: the scientific method involves making conjectures (hypothetical explanations), predicting the logical consequences of hypothesis, then carrying out experiments or empirical observations based on those predictions. A hypothesis is a conjecture based on knowledge obtained while seeking answers to
27263-409: The invisible dragon, so one can never prove that the initial claim is wrong. Sagan concludes; "Now, what's the difference between an invisible, incorporeal, floating dragon who spits heatless fire and no dragon at all?". He states that "your inability to invalidate my hypothesis is not at all the same thing as proving it true", once again explaining that even if such a claim were true, it would be outside
27462-411: The latter is more stable. Traditionally, philosophers have mainly focused in their inquiries concerning belief on the notion of belief-that . Belief-that can be characterized as a propositional attitude to a claim which is either true or false. Belief-in , on the other hand, is more closely related to notions like trust or faith in that it refers usually to an attitude to persons. Belief-in plays
27661-410: The laws of probability. This includes both synchronic laws about what one should believe at any moment and diachronic laws about how one should revise one's beliefs upon receiving new evidence. The central question in the dispute between full and partial beliefs is whether these two types are really distinct types or whether one type can be explained in terms of the other. One answer to this question
27860-491: The level of the theory as a whole. Another motivation is due to considerations of the nature of learning: it is often not possible to understand one concept, like force in Newtonian physics , without understanding other concepts, like mass or kinetic energy . One problem for holism is that genuine disagreements seem to be impossible or very rare: disputants would usually talk past each other since they never share exactly
28059-807: The major features of pseudoscience. Larry Laudan has suggested pseudoscience has no scientific meaning and is mostly used to describe human emotions: "If we would stand up and be counted on the side of reason, we ought to drop terms like 'pseudo-science' and 'unscientific' from our vocabulary; they are just hollow phrases which do only emotive work for us". Likewise, Richard McNally states, "The term 'pseudoscience' has become little more than an inflammatory buzzword for quickly dismissing one's opponents in media sound-bites" and "When therapeutic entrepreneurs make claims on behalf of their interventions, we should not waste our time trying to determine whether their interventions qualify as pseudoscientific. Rather, we should ask them: How do you know that your intervention works? What
28258-526: The means for determining length . These ideas were skipped over by Isaac Newton with, "I do not define time , space, place and motion , as being well known to all." Einstein's paper then demonstrates that they (viz., absolute time and length independent of motion) were approximations. Francis Crick cautions us that when characterizing a subject, however, it can be premature to define something when it remains ill-understood. In Crick's study of consciousness , he actually found it easier to study awareness in
28457-535: The mechanism of storing genetic information (i.e., genes) in DNA was unclear. Researchers in Bragg's laboratory at Cambridge University made X-ray diffraction pictures of various molecules , starting with crystals of salt , and proceeding to more complicated substances. Using clues painstakingly assembled over decades, beginning with its chemical composition, it was determined that it should be possible to characterize
28656-472: The mind. A more holistic alternative to the "language of thought hypothesis" is the map-conception , which uses an analogy of maps to elucidate the nature of beliefs. According to this view, the belief system of a mind should be conceived of not as a set of many individual sentences but as a map encoding the information contained in these sentences. For example, the fact that Brussels is halfway between Paris and Amsterdam can be expressed both linguistically as
28855-556: The more fantastical claims of religions and directly challenged religious authority and the prevailing beliefs associated with the established churches. In response to the liberalizing political and social movements, some religious groups attempted to integrate Enlightenment ideals of rationality, equality, and individual liberty into their belief systems, especially in the nineteenth and twentieth centuries. Reform Judaism and Liberal Christianity offer two examples of such religious associations. Adherents of particular religions deal with
29054-453: The more general distinction between reliable and unreliable knowledge. Belief A belief is a subjective attitude that a proposition is true or a state of affairs is the case. A subjective attitude is a mental state of having some stance , take, or opinion about something. In epistemology , philosophers use the term "belief" to refer to attitudes about the world which can be either true or false . To believe something
29253-726: The norms of scientific research, but it demonstrably fails to meet these norms. The Ministry of AYUSH in the Government of India is purposed with developing education, research and propagation of indigenous alternative medicine systems in India. The ministry has faced significant criticism for funding systems that lack biological plausibility and are either untested or conclusively proven as ineffective. Quality of research has been poor, and drugs have been launched without any rigorous pharmacological studies and meaningful clinical trials on Ayurveda or other alternative healthcare systems. There
29452-456: The numbers in between correspond to intermediate degrees of certainty. In the Bayesian approach , these degrees are interpreted as subjective probabilities : e.g. a belief of degree 0.9 that it will rain tomorrow means that the agent thinks that the probability of rain tomorrow is 90%. Bayesianism uses this relation between beliefs and probability to define the norms of rationality in terms of
29651-595: The official doctrine and descriptions of the beliefs offered by religious authorities do not always agree with the privately held beliefs of those who identify as members of a particular religion. For a broad classification of the kinds of religious belief, see below. First self-applied as a term to the conservative doctrine outlined by anti-modernist Protestants in the United States, "fundamentalism" in religious terms denotes strict adherence to an interpretation of scriptures that are generally associated with theologically conservative positions or traditional understandings of
29850-574: The origin of human beliefs. In the context of Ancient Greek thought , three related concepts were identified regarding the concept of belief: pistis , doxa , and dogma . Simplified, Pistis refers to " trust " and "confidence," doxa refers to " opinion " and "acceptance," and dogma refers to the positions of a philosopher or of a philosophical school such as Stoicism . Beliefs can be categorized into various types depending on their ontological status, their degree, their object or their semantic properties. Having an occurrent belief that
30049-405: The original conjecture was correct. However, there are difficulties in a formulaic statement of method. Though the scientific method is often presented as a fixed sequence of steps, these actions are more accurately general principles. Not all steps take place in every scientific inquiry (nor to the same degree), and they are not always done in the same order. There are different ways of outlining
30248-467: The other. Another example which shows the distinct need for a claim to be falsifiable was stated in Carl Sagan 's publication The Demon-Haunted World when he discusses an invisible dragon that he has in his garage. The point is made that there is no physical test to refute the claim of the presence of this dragon. Whatever test one thinks can be devised, there is a reason why it does not apply to
30447-431: The outcome of the investigation. The systematic, careful collection of measurements or counts of relevant quantities is often the critical difference between pseudo-sciences , such as alchemy, and science, such as chemistry or biology. Scientific measurements are usually tabulated, graphed, or mapped, and statistical manipulations, such as correlation and regression , performed on them. The measurements might be made in
30646-403: The part of those experimenting. Detailed record-keeping is essential, to aid in recording and reporting on the experimental results, and supports the effectiveness and integrity of the procedure. They will also assist in reproducing the experimental results, likely by others. Traces of this approach can be seen in the work of Hipparchus (190–120 BCE), when determining a value for the precession of
30845-403: The pertinent properties of the subjects, careful thought may also entail some definitions and observations ; these observations often demand careful measurements and/or counting can take the form of expansive empirical research . A scientific question can refer to the explanation of a specific observation , as in "Why is the sky blue?" but can also be open-ended, as in "How can I design
31044-588: The physical structure of DNA, and the X-ray images would be the vehicle. The scientific method depends upon increasingly sophisticated characterizations of the subjects of investigation. (The subjects can also be called unsolved problems or the unknowns .) For example, Benjamin Franklin conjectured, correctly, that St. Elmo's fire was electrical in nature , but it has taken a long series of experiments and theoretical changes to establish this. While seeking
31243-534: The power of intercessory prayer to heal the sick , although they may be based on untestable beliefs, can be tested by the scientific method. Some statements and common beliefs of popular science may not meet the criteria of science. "Pop" science may blur the divide between science and pseudoscience among the general public, and may also involve science fiction . Indeed, pop science is disseminated to, and can also easily emanate from, persons not accountable to scientific methodology and expert peer review. If claims of
31442-533: The predicted effect is definitely absent, then the theory is simply refuted." Popper summed up his criterion for the scientific status of a theory as depending on its falsifiability, refutability, or testability . Paul R. Thagard used astrology as a case study to distinguish science from pseudoscience and proposed principles and criteria to delineate them. First, astrology has not progressed in that it has not been updated nor added any explanatory power since Ptolemy . Second, it has ignored outstanding problems such as
31641-915: The prescribed medicine is not working. At that point, the patient has a great deal of flexibility in choosing what beliefs to keep or reject: the patient could believe that the doctor is incompetent, that the doctor's assistants made a mistake, that the patient's own body is unique in some unexpected way, that Western medicine is ineffective, or even that Western science is entirely unable to discover truths about ailments. This insight has relevance for inquisitors , missionaries , agitprop groups and thought-police . The British philosopher Stephen Law has described some belief systems (including belief in homeopathy , psychic powers , and alien abduction ) as "claptrap" and says that such belief-systems can "draw people in and hold them captive so they become willing slaves of claptrap ... if you get sucked in, it can be extremely difficult to think your way clear again". Religion
31840-424: The process at any stage. They might adopt the characterization and formulate their own hypothesis, or they might adopt the hypothesis and deduce their own predictions. Often the experiment is not done by the person who made the prediction, and the characterization is based on experiments done by someone else. Published results of experiments can also serve as a hypothesis predicting their own reproducibility. Science
32039-676: 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 denialism , Velikovskian catastrophism , and climate change denialism are pseudosciences." There are implications for health care ,
32238-468: The public's susceptibility to unproven claims. The NSF stated that pseudoscientific beliefs in the U.S. became more widespread during the 1990s, peaked about 2001, and then decreased slightly since with pseudoscientific beliefs remaining common. According to the NSF report, there is a lack of knowledge of pseudoscientific issues in society and pseudoscientific practices are commonly followed. Surveys indicate about
32437-486: The question. Hypotheses can be very specific or broad but must be falsifiable , implying that it is possible to identify a possible outcome of an experiment or observation that conflicts with predictions deduced from the hypothesis; otherwise, the hypothesis cannot be meaningfully tested. While the scientific method is often presented as a fixed sequence of steps, it actually represents a set of general principles. Not all steps take place in every scientific inquiry (nor to
32636-479: The realm of scientific inquiry . During 1942, Robert K. Merton identified a set of five "norms" which characterize real science. If any of the norms were violated, Merton considered the enterprise to be non-science. His norms were: In 1978, Paul Thagard proposed that pseudoscience is primarily distinguishable from science when it is less progressive than alternative theories over a long period of time, and its proponents fail to acknowledge or address problems with
32835-442: The realm of science. In the philosophy and history of science, Imre Lakatos stresses the social and political importance of the demarcation problem, the normative methodological problem of distinguishing between science and pseudoscience. His distinctive historical analysis of scientific methodology based on research programmes suggests: "scientists regard the successful theoretical prediction of stunning novel facts – such as
33034-597: The return of Halley's comet or the gravitational bending of light rays – as what demarcates good scientific theories from pseudo-scientific and degenerate theories, and in spite of all scientific theories being forever confronted by 'an ocean of counterexamples'". Lakatos offers a "novel fallibilist analysis of the development of Newton's celestial dynamics, [his] favourite historical example of his methodology" and argues in light of this historical turn, that his account answers for certain inadequacies in those of Karl Popper and Thomas Kuhn. "Nonetheless, Lakatos did recognize
33233-542: The right perceptions; for example, to believe that it is raining given a perception of rain. Without this perception, there is still a disposition to believe but no actual dispositional belief. On a dispositionalist conception of belief, there are no occurrent beliefs, since all beliefs are defined in terms of dispositions. An important dispute in formal epistemology concerns the question of whether beliefs should be conceptualized as full beliefs or as partial beliefs. Full beliefs are all-or-nothing attitudes: either one has
33432-525: The rule and is able to add justification ( logos : reasonable and necessarily plausible assertions/evidence/guidance) to it. A belief can be based fully or partially on intuition . Plato has been credited for the justified true belief theory of knowledge, even though Plato in the Theaetetus elegantly dismisses it, and even posits this argument of Socrates as a cause for his death penalty. The epistemologists, Gettier and Goldman , have questioned
33631-433: The same degree), and they are not always in the same order. Numerous discoveries have not followed the textbook model of the scientific method and chance has played a role, for instance. The history of scientific method considers changes in the methodology of scientific inquiry, not the history of science itself. The development of rules for scientific reasoning has not been straightforward; scientific method has been
33830-417: The same journal concluded there was no strong correlation between science knowledge and belief in pseudoscience. During 2006, the U.S. National Science Foundation (NSF) issued an executive summary of a paper on science and engineering which briefly discussed the prevalence of pseudoscience in modern times. It said, "belief in pseudoscience is widespread" and, referencing a Gallup Poll , stated that belief in
34029-424: The same molecular composition. So it seems necessary to include external factors in order to explain the difference. One problem with this position is that this difference in content does not bring any causal difference with it: the two readers act in exactly the same way. This casts doubt on the thesis that there is any genuine difference in need of explanation between the contents of the two beliefs. Epistemology
34228-507: The same web of beliefs needed to determine the content of the source of the disagreement. Internalism and externalism disagree about whether the contents of our beliefs are determined only by what's happening in our head or also by other factors. Internalists deny such a dependence on external factors. They hold that a person and a molecule-by-molecule copy would have exactly the same beliefs. Hilary Putnam objects to this position by way of his twin Earth thought experiment . He imagines
34427-461: The same. We vary the conditions for the acts of measurement, to help isolate what has changed. Mill's canons can then help us figure out what the important factor is. Factor analysis is one technique for discovering the important factor in an effect. Depending on the predictions, the experiments can have different shapes. It could be a classical experiment in a laboratory setting, a double-blind study or an archaeological excavation . Even taking
34626-422: The scientific era. Others developed as part of an ideology, such as Lysenkoism , or as a response to perceived threats to an ideology. Examples of this ideological process are creation science and intelligent design , which were developed in response to the scientific theory of evolution . A topic, practice, or body of knowledge might reasonably be termed pseudoscientific when it is presented as consistent with
34825-422: The scientific method are illustrated by the following example (which occurred from 1944 to 1953) from the discovery of the structure of DNA (marked with [REDACTED] and indented). [REDACTED] In 1950, it was known that genetic inheritance had a mathematical description, starting with the studies of Gregor Mendel , and that DNA contained genetic information (Oswald Avery's transforming principle ). But
35024-913: The scientific methodology and conclusions reached by the article Stephens cited has been called into question repeatedly since its publication. It has been found that at least one of that study's authors has been identified by the Southern Poverty Law Center as a white nationalist. The journal Nature has published a number of editorials in the last few years warning researchers about extremists looking to abuse their work, particularly population geneticists and those working with ancient DNA . One article in Nature , titled "Racism in Science: The Taint That Lingers" notes that early-twentieth-century eugenic pseudoscience has been used to influence public policy, such as
35223-413: The scientist to repeat an earlier part of the process. Failure to develop an interesting hypothesis may lead a scientist to re-define the subject under consideration. Failure of a hypothesis to produce interesting and testable predictions may lead to reconsideration of the hypothesis or of the definition of the subject. Failure of an experiment to produce interesting results may lead a scientist to reconsider
35422-474: The sentence "Superman is strong" without changing its truth-value; this issue is more complicated in case of belief ascriptions. For example, Lois believes that Superman is strong but she does not believe that Clark Kent is strong. This difficulty arises due to the fact that she does not know that the two names refer to the same entity. Beliefs or belief ascriptions for which this substitution does not generally work are de dicto , otherwise, they are de re . In
35621-411: The specific pairing we have postulated immediately suggests a possible copying mechanism for the genetic material". Any useful hypothesis will enable predictions , by reasoning including deductive reasoning . It might predict the outcome of an experiment in a laboratory setting or the observation of a phenomenon in nature. The prediction can also be statistical and deal only with probabilities. It
35820-460: The subject of intense and recurring debate throughout the history of science, and eminent natural philosophers and scientists have argued for the primacy of various approaches to establishing scientific knowledge. Different early expressions of empiricism and the scientific method can be found throughout history, for instance with the ancient Stoics , Epicurus , Alhazen , Avicenna , Al-Biruni , Roger Bacon , and William of Ockham . In
36019-404: The tendency to revise one's belief upon receiving new evidence that an existing belief is false. Upon hearing a forecast of bad weather, Rahul is likely to change his mental attitude but Sofía is not. There are different ways of conceiving how mental representations are realized in the mind. One form of this is the language of thought hypothesis , which claims that mental representations have
36218-528: The term has been in use since at least the late 18th century (e.g., in 1796 by James Pettit Andrews in reference to alchemy ), the concept of pseudoscience as distinct from real or proper science seems to have become more widespread during the mid-19th century. Among the earliest uses of "pseudo-science" was in an 1844 article in the Northern Journal of Medicine , issue 387: That opposite kind of innovation which pronounces what has been recognized as
36417-407: The text and are distrustful of innovative readings, new revelation, or alternative interpretations. Religious fundamentalism has been identified in the media as being associated with fanatical or zealous political movements around the world that have used a strict adherence to a particular religious doctrine as a means to establish political identity and to enforce societal norms. First used in
36616-469: The theory. In 1983, Mario Bunge suggested the categories of "belief fields" and "research fields" to help distinguish between pseudoscience and science, where the former is primarily personal and subjective and the latter involves a certain systematic method. The 2018 book about scientific skepticism by Steven Novella , et al. The Skeptics' Guide to the Universe lists hostility to criticism as one of
36815-582: The title of Against Method , accepted certain rules of method and attempted to justify those rules with a meta methodology. Staddon (2017) argues it is a mistake to try following rules in the absence of an algorithmic scientific method; in that case, "science is best understood through examples". But algorithmic methods, such as disproof of existing theory by experiment have been used since Alhacen (1027) and his Book of Optics , and Galileo (1638) and his Two New Sciences , and The Assayer , which still stand as scientific method. The scientific method
37014-468: The traditional view." On the other hand, Paul Boghossian argues that the justified true belief account is the "standard, widely accepted" definition of knowledge. A belief system comprises a set of mutually supportive beliefs. The beliefs of any such system can be religious , philosophical , political , ideological , or a combination of these. The British philosopher Jonathan Glover , following Meadows (2008), says that beliefs are always part of
37213-416: The twentieth century; Dewey's 1910 book , How We Think , inspired popular guidelines , appearing in dictionaries and science textbooks, although there was little consensus over its meaning. Although there was growth through the middle of the twentieth century, by the 1960s and 1970s numerous influential philosophers of science such as Thomas Kuhn and Paul Feyerabend had questioned the universality of
37412-455: The two distinctions do not match. The reason for this is that beliefs can shape one's behaviour and be involved in one's reasoning even if the subject is not conscious of them. Such beliefs are cases of unconscious occurrent mental states. On this view, being occurrent corresponds to being active, either consciously or unconsciously. A dispositional belief is not the same as a disposition to believe. We have various dispositions to believe given
37611-404: The typical descriptive unit of great scientific achievements is not an isolated hypothesis but "a powerful problem-solving machinery, which, with the help of sophisticated mathematical techniques, digests anomalies and even turns them into positive evidence". To Popper, pseudoscience uses induction to generate theories, and only performs experiments to seek to verify them. To Popper, falsifiability
37810-518: The usage of the word occurred in a more formal, technical manner in response to a perceived threat to individual and institutional security in a social and cultural setting. Pseudoscience is differentiated from science because – although it usually claims to be science – pseudoscience does not adhere to scientific standards, such as the scientific method , falsifiability of claims , and Mertonian norms . A number of basic principles are accepted by scientists as standards for determining whether
38009-423: The use of expert testimony , and weighing environmental policies . Recent empirical research has shown that individuals who indulge in pseudoscientific beliefs generally show lower evidential criteria, meaning they often require significantly less evidence before coming to conclusions. This can be coined as a 'jump-to-conclusions' bias that can increase the spread of pseudoscientific beliefs. Addressing pseudoscience
38208-476: The viability of the belief concept stems from philosophical analysis. The concept of belief presumes a subject (the believer) and an object of belief (the proposition). Like other propositional attitudes , belief implies the existence of mental states and intentionality , both of which are hotly debated topics in the philosophy of mind , whose foundations and relation to brain states are still controversial. Scientific method The scientific method
38407-423: The work may be better described as ideas that are "not yet generally accepted". Protoscience is a term sometimes used to describe a hypothesis that has not yet been tested adequately by the scientific method, but which is otherwise consistent with existing science or which, where inconsistent, offers reasonable account of the inconsistency. It may also describe the transition from a body of practical knowledge into
38606-434: The work of Cochran, Crick and Vand (and independently by Stokes). The Cochran-Crick-Vand-Stokes theorem provided a mathematical explanation for the empirical observation that diffraction from helical structures produces x-shaped patterns. In their first paper, Watson and Crick also noted that the double helix structure they proposed provided a simple mechanism for DNA replication , writing, "It has not escaped our notice that
38805-405: Was able to infer that Earth's atmosphere was 50 miles thick, based on atmospheric refraction of the sun's rays. This is why the scientific method is often represented as circular – new information leads to new characterisations, and the cycle of science continues. Measurements collected can be archived , passed onwards and used by others. Other scientists may start their own research and enter
39004-399: Was adopted as a United Russia party project; in the version submitted to the government, the program budget for 2010–2017 exceeded $ 14 billion. There have been many connections between pseudoscientific writers and researchers and their anti-semitic, racist and neo-Nazi backgrounds. They often use pseudoscience to reinforce their beliefs. One of the most predominant pseudoscientific writers
39203-409: Was also considered by Francis Crick and James D. Watson but discarded. When Watson and Crick learned of Pauling's hypothesis, they understood from existing data that Pauling was wrong. and that Pauling would soon admit his difficulties with that structure. A hypothesis is a suggested explanation of a phenomenon, or alternately a reasoned proposal suggesting a possible correlation between or among
39402-488: Was exemplified by astrology, which appeals to observation and experimentation. While it had empirical evidence based on observation, on horoscopes and biographies , it crucially failed to use acceptable scientific standards. Popper proposed falsifiability as an important criterion in distinguishing science from pseudoscience. To demonstrate this point, Popper gave two cases of human behavior and typical explanations from Sigmund Freud and Alfred Adler 's theories: "that of
39601-587: Was particular development aided by theoretical works by a skeptic Francisco Sanches , by idealists as well as empiricists John Locke , George Berkeley , and David Hume . C. S. Peirce formulated the hypothetico-deductive model in the 20th century, and the model has undergone significant revision since. The term "scientific method" emerged in the 19th century, as a result of significant institutional development of science, and terminologies establishing clear boundaries between science and non-science, such as "scientist" and "pseudoscience", appearing.
