115-417: Paleobiological research uses biological field research of current biota and of fossils millions of years old to answer questions about the molecular evolution and the evolutionary history of life . In this scientific quest, macrofossils , microfossils and trace fossils are typically analyzed. However, the 21st-century biochemical analysis of DNA and RNA samples offers much promise, as does

230-415: A consensus to emerge since the different parties may be unable to agree even on what the evidence is. When understood in the widest sense, it is not controversial that some form of theory-ladenness exists. But it is questionable whether it constitutes a serious threat to scientific evidence when understood in this sense. Philosophers in the 20th century started to investigate the "evidential relation",

345-405: A criminal act. The focus of criminal evidence is to connect physical evidence and reports of witnesses to a specific person. The path that physical evidence takes from the scene of a crime or the arrest of a suspect to the courtroom is called the chain of custody . In a criminal case, this path must be clearly documented or attested to by those who handled the evidence. If the chain of evidence

460-410: A research question is identified. A gap in the current literature, as identified by a researcher, then engenders a research question. The research question may be parallel to the hypothesis . The hypothesis is the supposition to be tested. The researcher(s) collects data to test the hypothesis. The researcher(s) then analyzes and interprets the data via a variety of statistical methods, engaging in what

575-569: A "public domain", that of "humanity". This idea gained prevalence as a result of Western colonial history and ignores alternative conceptions of knowledge circulation. For instance, most indigenous communities consider that access to certain information proper to the group should be determined by relationships. There is alleged to be a double standard in the Western knowledge system. On the one hand, "digital right management" used to restrict access to personal information on social networking platforms

690-403: A case. The decision-maker, often a jury, but sometimes a judge decides whether the burden of proof has been fulfilled. After deciding who will carry the burden of proof, the evidence is first gathered and then presented before the court: In a criminal investigation, rather than attempting to prove an abstract or hypothetical point, the evidence gatherers attempt to determine who is responsible for

805-467: A non-empirical task is the prototyping of a new drug using a differentiated application of existing knowledge; another is the development of a business process in the form of a flow chart and texts where all the ingredients are from established knowledge. Much of cosmological research is theoretical in nature. Mathematics research does not rely on externally available data; rather, it seeks to prove theorems about mathematical objects . Research ethics

920-408: A novel interpretation of previous results. In analytical work, there are typically some new (for example) mathematical results produced or a new way of approaching an existing problem. In some subjects which do not typically carry out experimentation or analysis of this kind, the originality is in the particular way existing understanding is changed or re-interpreted based on the outcome of the work of

1035-492: A perceived failure to fulfill the burden of proof. Two principal considerations are: The latter question depends on the nature of the point under contention and determines the quantity and quality of evidence required to meet the burden of proof. In a criminal trial in the United States, for example, the prosecution carries the burden of proof since the defendant is presumed innocent until proven guilty beyond

1150-453: A philosophical debate , there is an implicit burden of proof on the party asserting a claim, since the default position is generally one of neutrality or unbelief. Each party in a debate will therefore carry the burden of proof for any assertion they make in the argument, although some assertions may be granted by the other party without further evidence. If the debate is set up as a resolution to be supported by one side and refuted by another,

1265-447: A pre-existing hypothesis. Logical positivists , on the other hand, held that this priority is semantic in nature, i.e. that the meanings of the theoretical terms used in the hypothesis are determined by what would count as evidence for them. Counterexamples for this view come from the fact that our idea of what counts as evidence may change while the meanings of the corresponding theoretical terms remain constant. The most plausible view

1380-530: A proposition is evidence for a hypothesis if it entails the "development of the hypothesis". Intuitively, the development of the hypothesis is what the hypothesis states if it was restricted to only the individuals mentioned in the evidence. In the case above, we have the hypothesis " ∀ x ( s w a n ( x ) → w h i t e ( x ) ) {\displaystyle \forall x(swan(x)\rightarrow white(x))} " (all swans are white) which, when restricted to

1495-408: A reasonable doubt . Similarly, in most civil procedures , the plaintiff carries the burden of proof and must convince a judge or jury that the preponderance of the evidence is on their side. Other legal standards of proof include "reasonable suspicion", "probable cause" (as for arrest ), " prima facie evidence", "credible evidence", "substantial evidence", and "clear and convincing evidence". In

1610-468: A research approach. Neither one is less effective than the other since they have their particular purpose in science. Typically empirical research produces observations that need to be explained; then theoretical research tries to explain them, and in so doing generates empirically testable hypotheses; these hypotheses are then tested empirically, giving more observations that may need further explanation; and so on. See Scientific method . A simple example of

1725-435: A simpler formula would appear more evident to them. Riofrio has detected some characteristics that are present in evident arguments and proofs. The more they are evident, the more these characteristics will be present. There are six intrinsic characteristics of evidence: In addition, four subjective or external characteristics can be detected over those things that are more or less evident: These ten characteristics of what

1840-493: A single, all-encompassing definition that is embraced by all who engage in it. Research, in its simplest terms, is searching for knowledge and searching for truth. In a formal sense, it is a systematic study of a problem attacked by a deliberately chosen strategy, which starts with choosing an approach to preparing a blueprint (design) and acting upon it in terms of designing research hypotheses, choosing methods and techniques, selecting or developing data collection tools, processing

1955-460: A symptom of the truth of the hypothesis. Against this approach, it has been argued that it is too liberal because it allows accidental generalizations as evidence. Finding a nickel in one's pocket, for example, raises the probability of the hypothesis that "All the coins in my pockets are nickels". But, according to Alvin Goldman , it should not be considered evidence for this hypothesis since there

2070-455: A variety of approaches, such as queer theory or feminist theory. Artistic research , also seen as 'practice-based research', can take form when creative works are considered both the research and the object of research itself. It is the debatable body of thought which offers an alternative to purely scientific methods in research in its search for knowledge and truth. The controversial trend of artistic teaching becoming more academics-oriented

2185-418: Is " creative and systematic work undertaken to increase the stock of knowledge ". It involves the collection, organization, and analysis of evidence to increase understanding of a topic, characterized by a particular attentiveness to controlling sources of bias and error . These activities are characterized by accounting and controlling for biases. A research project may be an expansion of past work in

2300-521: Is a discipline within the study of applied ethics . Its scope ranges from general scientific integrity and misconduct to the treatment of human and animal subjects. The social responsibilities of scientists and researchers are not traditionally included and are less well defined. The discipline is most developed in medical research . Beyond the issues of falsification, fabrication, and plagiarism that arise in every scientific field, research design in human subject research and animal testing are

2415-448: Is accumulated through observations of phenomena that occur in the natural world, or which are created as experiments in a laboratory or other controlled conditions. Scientists tend to focus on how the data used during statistical inference are generated. Scientific evidence usually goes towards supporting or rejecting a hypothesis . The burden of proof is on the person making a contentious claim. Within science, this translates to

2530-462: Is an approach that involves the development of theory as opposed to using observation and experimentation. As such, non-empirical research seeks solutions to problems using existing knowledge as its source. This, however, does not mean that new ideas and innovations cannot be found within the pool of existing and established knowledge. Non-empirical research is not an absolute alternative to empirical research because they may be used together to strengthen

2645-590: Is becoming more common. This method has benefits that using one method alone cannot offer. For example, a researcher may choose to conduct a qualitative study and follow it up with a quantitative study to gain additional insights. Big data has brought big impacts on research methods so that now many researchers do not put much effort into data collection; furthermore, methods to analyze easily available huge amounts of data have also been developed. Types of Research Method 1. Observatory Research Method 2. Correlation Research Method Non-empirical ( theoretical ) research

2760-620: Is broken, a defendant may be able to persuade the judge to declare the evidence inadmissible . Presenting evidence before the court differs from the gathering of evidence in important ways. Gathering evidence may take many forms; presenting evidence that tends to prove or disprove the point at issue is strictly governed by rules. Failure to follow these rules leads to any number of consequences. In law, certain policies allow (or require) evidence to be excluded from consideration based either on indicia relating to reliability, or broader social concerns. Testimony (which tells) and exhibits (which show) are

2875-436: Is built. This evidence-based method is meant to make it possible for philosophy to overcome many of the traditionally unresolved disagreements and thus become a rigorous science. This far-reaching claim of phenomenology, based on absolute certainty, is one of the focal points of criticism by its opponents. Thus, it has been argued that even knowledge based on self-evident intuition is fallible. This can be seen, for example, in

2990-472: Is celebrated as a protection of privacy, while simultaneously when similar functions are used by cultural groups (i.e. indigenous communities) this is denounced as "access control" and reprehended as censorship. Evidence Evidence for a proposition is what supports the proposition. It is usually understood as an indication that the proposition is true . The exact definition and role of evidence vary across different fields. In epistemology , evidence

3105-485: Is closely related to the idea that how rational someone is, is determined by how they respond to evidence. Another intuition, which is more dominant in the philosophy of science, focuses on evidence as that which confirms scientific hypotheses and arbitrates between competing theories. On this view, it is essential that evidence is public so that different scientists can share the same evidence. This leaves publicly observable phenomena like physical objects and events as

3220-408: Is data collected specifically for the research, such as through interviews or questionnaires. Secondary data is data that already exists, such as census data, which can be re-used for the research. It is good ethical research practice to use secondary data wherever possible. Mixed-method research, i.e. research that includes qualitative and quantitative elements, using both primary and secondary data,

3335-535: Is elevated to one of the basic principles of philosophy, giving philosophy the ultimate justifications that are supposed to turn it into a rigorous science. In a more modern usage, the plural form is also used. In academic discourse, evidence plays a central role in epistemology and in the philosophy of science . Reference to evidence is made in many different fields, like in science, in the legal system, in history, in journalism and in everyday discourse. A variety of different attempts have been made to conceptualize

3450-492: Is especially relevant for choosing between competing theories. So in the case above, evidence plays the role of neutral arbiter between Newton's and Einstein's theory of gravitation. This is only possible if scientific evidence is public and uncontroversial so that proponents of competing scientific theories agree on what evidence is available. These requirements suggest scientific evidence consists not of private mental states but of public physical objects or events . It

3565-741: Is evident allowed Riofrio to formulate a test of evidence to detect the level of certainty or evidence that one argument or proof could have. Important theorists of evidence include Bertrand Russell , Willard Van Orman Quine , the logical positivists , Timothy Williamson , Earl Conee and Richard Feldman. Russell, Quine and the logical positivists belong to the empiricist tradition and hold that evidence consists in sense data, stimulation of one's sensory receptors and observation statements, respectively. According to Williamson, all and only knowledge constitute evidence. Conee and Feldman hold that only one's current mental states should be considered evidence. The guiding intuition within epistemology concerning

3680-415: Is known as empirical research . The results of the data analysis in rejecting or failing to reject the null hypothesis are then reported and evaluated. At the end, the researcher may discuss avenues for further research . However, some researchers advocate for the reverse approach: starting with articulating findings and discussion of them, moving "up" to identification of a research problem that emerges in

3795-583: Is known as meta-research . A researcher is a person who conducts research, especially in order to discover new information or to reach a new understanding. In order to be a social researcher or a social scientist , one should have enormous knowledge of subjects related to social science that they are specialized in. Similarly, in order to be a natural science researcher, the person should have knowledge of fields related to natural science ( physics , chemistry , biology , astronomy , zoology and so on). Professional associations provide one pathway to mature in

3910-454: Is leading to artistic research being accepted as the primary mode of enquiry in art as in the case of other disciplines. One of the characteristics of artistic research is that it must accept subjectivity as opposed to the classical scientific methods. As such, it is similar to the social sciences in using qualitative research and intersubjectivity as tools to apply measurement and critical analysis. Artistic research has been defined by

4025-402: Is no lawful connection between this one nickel and the other coins in the pocket. Hypothetico-deductivism is a non-probabilistic approach that characterizes the evidential relations in terms of deductive consequences of the hypothesis. According to this view, "evidence for a hypothesis is a true observational consequence of that hypothesis". One problem with the characterization so far

4140-461: Is no unitary concept corresponding to the different theoretical roles ascribed to evidence, i.e. that we do not always mean the same thing when we talk of evidence. On the other hand, Aristotle, phenomenologists, and numerous scholars accept that there could be several degrees of evidence. For instance, while the outcome of a complex equation may become more or less evident to a mathematician after hours of deduction, yet with little doubts about it,

4255-460: Is not feasible, the researcher may collect data on participant and situational characteristics to statistically control for their influence on the dependent, or outcome, variable. If the intent is to generalize from the research participants to a larger population, the researcher will employ probability sampling to select participants. In either qualitative or quantitative research, the researcher(s) may collect primary or secondary data. Primary data

4370-1012: Is often biased in the languages that are preferred ( linguicism ) and the geographic locations where research occurs. Periphery scholars face the challenges of exclusion and linguicism in research and academic publication. As the great majority of mainstream academic journals are written in English, multilingual periphery scholars often must translate their work to be accepted to elite Western-dominated journals. Multilingual scholars' influences from their native communicative styles can be assumed to be incompetence instead of difference. For comparative politics, Western countries are over-represented in single-country studies, with heavy emphasis on Western Europe, Canada, Australia, and New Zealand. Since 2000, Latin American countries have become more popular in single-country studies. In contrast, countries in Oceania and

4485-478: Is often combined with the idea that evidence, propositional or otherwise, determines what it is rational for us to believe. But it can be rational to have a false belief. This is the case when we possess misleading evidence. For example, it was rational for Neo in the Matrix movie to believe that he was living in the 20th century because of all the evidence supporting his belief despite the fact that this evidence

4600-534: Is often held as an argument against this view since sensory impressions are commonly treated as evidence. Propositionalism is sometimes combined with the view that only attitudes to true propositions can count as evidence. On this view, the belief that the corner shop sells milk only constitutes evidence for the belief that the corner shop sells dairy products if the corner shop actually sells milk. Against this position, it has been argued that evidence can be misleading but still count as evidence. This line of thought

4715-411: Is often held that evidence is in some sense prior to the hypotheses it confirms. This was sometimes understood as temporal priority , i.e. that we come first to possess the evidence and later form the hypothesis through induction. But this temporal order is not always reflected in scientific practice, where experimental researchers may look for a specific piece of evidence in order to confirm or disconfirm

4830-515: Is only when a range of tests are consistent over many kinds of data, researchers, and methods can one have confidence in the results." Plato in Meno talks about an inherent difficulty, if not a paradox, of doing research that can be paraphrased in the following way, "If you know what you're searching for, why do you search for it?! [i.e., you have already found it] If you don't know what you're searching for, what are you searching for?!" The goal of

4945-426: Is sometimes held that only propositional mental states can play this role, a position known as "propositionalism". A mental state is propositional if it is an attitude directed at a propositional content. Such attitudes are usually expressed by verbs like "believe" together with a that-clause, as in "Robert believes that the corner shop sells milk". Such a view denies that sensory impressions can act as evidence. This

5060-403: Is that hypotheses usually contain relatively little information and therefore have few if any deductive observational consequences. So the hypothesis by itself that there is a fire does not entail that smoke is observed. Instead, various auxiliary assumptions have to be included about the location of the smoke, the fire, the observer, the lighting conditions, the laws of chemistry, etc. In this way,

5175-402: Is that justified belief has to be connected to or grounded in the mental state acting as its evidence. So Phoebe's belief that the speakers are on is not justified by her auditory experience if the belief is not based in this experience. This would be the case, for example, if Phoebe has both the experience and the belief but is unaware of the fact that the music is produced by the speakers. It

5290-532: Is that this priority is epistemic in nature, i.e. that our belief in a hypothesis is justified based on the evidence while the justification for the belief in the evidence does not depend on the hypothesis. A central issue for the scientific conception of evidence is the problem of underdetermination , i.e. that the evidence available supports competing theories equally well. So, for example, evidence from our everyday life about how gravity works confirms Newton's and Einstein's theory of gravitation equally well and

5405-415: Is the hypothesis rejected: this can be referred to as ' refutation of the hypothesis'. The rules for evidence used by science are collected systematically in an attempt to avoid the bias inherent to anecdotal evidence . In law, the production and presentation of evidence depend first on establishing on whom the burden of proof lies. Admissible evidence is that which a court receives and considers for

5520-420: Is therefore unable to establish consensus among scientists. But in such cases, it is often the gradual accumulation of evidence that eventually leads to an emerging consensus. This evidence-driven process towards consensus seems to be one hallmark of the sciences not shared by other fields. Another problem for the conception of evidence in terms of confirmation of hypotheses is that what some scientists consider

5635-736: Is very powerful strategy for demonstrating methodology to health professions education as well as best suited for exploring challenging problems in health professions educations. In addition, PMP researcher Mandy Sha argued that a project management approach is necessary to control the scope, schedule, and cost related to qualitative research design, participant recruitment, data collection, reporting, as well as stakeholder engagement . The quantitative data collection methods rely on random sampling and structured data collection instruments that fit diverse experiences into predetermined response categories. These methods produce results that can be summarized, compared, and generalized to larger populations if

5750-449: Is what justifies beliefs or what makes it rational to hold a certain doxastic attitude. For example, a perceptual experience of a tree may serve as evidence to justify the belief that there is a tree. In this role, evidence is usually understood as a private mental state . In phenomenology , evidence is limited to intuitive knowledge, often associated with the controversial assumption that it provides indubitable access to truth. In

5865-499: Is why evidence is often associated with the controversial thesis that it constitutes an immediate access to truth. In this sense, the evidently given phenomenon guarantees its own truth and is therefore considered indubitable. Due to this special epistemological status of evidence, it is regarded in phenomenology as the basic principle of all philosophy. In this form, it represents the lowest foundation of knowledge, which consists of indubitable insights upon which all subsequent knowledge

In 1993, Schopf discovered O 2 -producing blue-green bacteria at his 3.5 billion-year-old Apex Chert site in Pilbara Craton , Marble Bar , in the northwestern part of Western Australia . So paleobiologists were at last homing in on the origins of the Precambrian " Oxygen catastrophe ". During the early part of the 21st-century, two paleobiologists Anjali Goswami and Thomas Halliday, studied

Patterns of geographic bias also show a relationship with linguicism: countries whose official languages are French or Arabic are far less likely to be the focus of single-country studies than countries with different official languages. Within Africa, English-speaking countries are more represented than other countries. Generalization is the process of more broadly applying

The Florence Principles relating to the Salzburg Principles and the Salzburg Recommendations of the European University Association name seven points of attention to specify the Doctorate / PhD in the Arts compared to a scientific doctorate / PhD. The Florence Principles have been endorsed and are supported also by AEC , CILECT , CUMULUS and SAR . The historical method comprises

It is based on artistic practices, methods, and criticality. Through presented documentation, the insights gained shall be placed in a context." Artistic research aims to enhance knowledge and understanding with presentation of

6440-496: The biometric construction of phylogenetic trees . An investigator in this field is known as a paleobiologist . The founder or "father" of modern paleobiology was Baron Franz Nopcsa (1877 to 1933), a Hungarian scientist trained at the University of Vienna. He initially termed the discipline "paleophysiology". However, credit for coining the word paleobiology itself should go to Professor Charles Schuchert . He proposed

6555-441: The philosophy of science , evidence is material that confirms or disconfirms scientific hypotheses , acting as a neutral arbiter between competing theories. Measurements of Mercury's "anomalous" orbit , for example, are seen as evidence that confirms Einstein 's theory of general relativity . Philosophers of science tend to understand evidence not as mental states but as observable physical objects or events, secured by following

6670-451: The researcher . The degree of originality of the research is among the major criteria for articles to be published in academic journals and usually established by means of peer review . Graduate students are commonly required to perform original research as part of a dissertation . Scientific research is a systematic way of gathering data and harnessing curiosity . This research provides scientific information and theories for

6785-642: The scientific lacuna in culturally sensitive methods of data collection. Western methods of data collection may not be the most accurate or relevant for research on non-Western societies. For example, " Hua Oranga " was created as a criterion for psychological evaluation in Māori populations, and is based on dimensions of mental health important to the Māori people – "taha wairua (the spiritual dimension), taha hinengaro (the mental dimension), taha tinana (the physical dimension), and taha whanau (the family dimension)". Research

6900-468: The scientific method . The problems of underdetermination and theory-ladenness are two obstacles that threaten to undermine the role of scientific evidence. In law , evidence is information to establish or refute claims relevant to a case, such as testimony , documentary evidence , and physical evidence . The relation between evidence and a supported statement can vary in strength, ranging from weak correlation to indisputable proof . Theories of

In 1899 he discovered the first acritarch fossil cells, a Precambrian algal phytoplankton he named Chuaria . Lastly, in 1914, Walcott reported "minute cells and chains of cell-like bodies" belonging to Precambrian purple bacteria . Later 20th-century paleobiologists have also figured prominently in finding Archaean and Proterozoic eon microfossils : In 1954, Stanley A. Tyler and Elso S.

7130-528: The 1978 Belmont Report . Today, research ethics committees , such as those of the US , UK , and EU , govern and oversee the responsible conduct of research. Meta-research is the study of research through the use of research methods. Also known as "research on research", it aims to reduce waste and increase the quality of research in all fields. Meta-research concerns itself with the detection of bias, methodological flaws, and other errors and inefficiencies. Among

7245-458: The accuracy of observation of the time, the prediction will be verified. As the accuracy of observation improves with time, the hypothesis may no longer provide an accurate prediction. In this case, a new hypothesis will arise to challenge the old, and to the extent that the new hypothesis makes more accurate predictions than the old, the new will supplant it. Researchers can also use a null hypothesis, which states no relationship or difference between

The list of historic cases includes many large-scale violations and crimes against humanity such as Nazi human experimentation and the Tuskegee syphilis experiment which led to international codes of research ethics. No approach has been universally accepted, but typically-cited codes are the 1947 Nuremberg Code , the 1964 Declaration of Helsinki , and

7475-756: The arts. A simpler understanding by Julian Klein defines artistic research as any kind of research employing the artistic mode of perception. For a survey of the central problematics of today's artistic research, see Giaco Schiesser . According to artist Hakan Topal , in artistic research, "perhaps more so than other disciplines, intuition is utilized as a method to identify a wide range of new and unexpected productive modalities". Most writers, whether of fiction or non-fiction books, also have to do research to support their creative work. This may be factual, historical, or background research. Background research could include, for example, geographical or procedural research. The Society for Artistic Research (SAR) publishes

7590-413: The best candidates for evidence, unlike private mental states. One problem with these approaches is that the resulting definitions of evidence, both within a field and between fields, vary a lot and are incompatible with each other. For example, it is not clear what a bloody knife and a perceptual experience have in common when both are treated as evidence in different disciplines. This suggests that there

7705-412: The burden resting on presenters of a paper, in which the presenters argue for their specific findings. This paper is placed before a panel of judges where the presenter must defend the thesis against all challenges. When evidence is contradictory to predicted expectations, the evidence and the ways of making it are often closely scrutinized (see experimenter's regress ) and only at the end of this process

7820-409: The conditional probability of this hypothesis relative to the evidence is higher than the unconditional probability of the hypothesis by itself. Smoke (E), for example, is evidence that there is a fire (H), because the two usually occur together, which is why the likelihood of fire given that there is smoke is higher than the likelihood of fire by itself. On this view, evidence is akin to an indicator or

7935-422: The data are collected using proper sampling and data collection strategies. Quantitative research is concerned with testing hypotheses derived from theory or being able to estimate the size of a phenomenon of interest. If the research question is about people, participants may be randomly assigned to different treatments (this is the only way that a quantitative study can be considered a true experiment). If this

8050-623: The data, interpretation, and ending with presenting solution(s) of the problem. Another definition of research is given by John W. Creswell , who states that "research is a process of steps used to collect and analyze information to increase our understanding of a topic or issue". It consists of three steps: pose a question, collect data to answer the question, and present an answer to the question. The Merriam-Webster Online Dictionary defines research more generally to also include studying already existing knowledge: "studious inquiry or examination; especially : investigation or experimentation aimed at

8165-424: The discovery and interpretation of facts, revision of accepted theories or laws in the light of new facts, or practical application of such new or revised theories or laws". Original research , also called primary research , is research that is not exclusively based on a summary, review, or synthesis of earlier publications on the subject of research. This material is of a primary-source character. The purpose of

8280-399: The domain "{a}", containing only the one individual mentioned in the evidence, entails the evidence, i.e. " s w a n ( a ) ∧ w h i t e ( a ) {\displaystyle swan(a)\land white(a)} " (this swan is white). One important shortcoming of this approach is that it requires that the hypothesis and the evidence are formulated in

8395-455: The evidence to be may already involve various theoretical assumptions not shared by other scientists. This phenomenon is known as theory-ladenness . Some cases of theory-ladenness are relatively uncontroversial, for example, that the numbers output by a measurement device need additional assumptions about how this device works and what was measured in order to count as meaningful evidence. Other putative cases are more controversial, for example,

8510-518: The evidential relation becomes a three-place relation between evidence, hypothesis and auxiliary assumptions. This means that whether a thing is evidence for a hypothesis depends on the auxiliary assumptions one holds. This approach fits well with various scientific practices. For example, it is often the case that experimental scientists try to find evidence that would confirm or disconfirm a proposed theory. The hypothetico-deductive approach can be used to predict what should be observed in an experiment if

8625-403: The evidential relation examine the nature of this connection. Probabilistic approaches hold that something counts as evidence if it increases the probability of the supported statement. According to hypothetico-deductivism , evidence consists in observational consequences of a hypothesis. The positive-instance approach states that an observation sentence is evidence for a universal statement if

8740-409: The evidential relation in terms of probabilities. They hold that all that is necessary is that the existence of the evidence increases the likelihood that the hypothesis is true. This can be expressed mathematically as P ( H ∣ E ) > P ( H ) {\displaystyle P(H\mid E)>P(H)} . In words: a piece of evidence (E) confirms a hypothesis (H) if

According to the positive-instance approach , an observation sentence is evidence for a universal hypothesis if the sentence describes a positive instance of this hypothesis. For example, the observation that "this swan is white" is an instance of the universal hypothesis that "all swans are white". This approach can be given a precise formulation in first-order logic :

9200-449: The fact that even among phenomenologists, there is much disagreement about the basic structures of experience. In the sciences, evidence is understood as what confirms or disconfirms scientific hypotheses . The term "confirmation" is sometimes used synonymously with that of "evidential support". Measurements of Mercury's "anomalous" orbit, for example, are seen as evidence that confirms Einstein's theory of general relativity. This

9315-730: The field. To test the validity of instruments, procedures, or experiments, research may replicate elements of prior projects or the project as a whole. The primary purposes of basic research (as opposed to applied research ) are documentation , discovery , interpretation , and the research and development (R&D) of methods and systems for the advancement of human knowledge. Approaches to research depend on epistemologies , which vary considerably both within and between humanities and sciences. There are several forms of research: scientific , humanities , artistic , economic, social , business, marketing , practitioner research , life, technological , etc. The scientific study of research practices

9430-460: The finding of meta-research is a low rates of reproducibility across a large number of fields. This widespread difficulty in reproducing research has been termed the " replication crisis ." In many disciplines, Western methods of conducting research are predominant. Researchers are overwhelmingly taught Western methods of data collection and study. The increasing participation of indigenous peoples as researchers has brought increased attention to

9545-400: The findings and literature review. The reverse approach is justified by the transactional nature of the research endeavor where research inquiry, research questions, research method, relevant research literature, and so on are not fully known until the findings have fully emerged and been interpreted. Rudolph Rummel says, "... no researcher should accept any one or two tests as definitive. It

9660-461: The following concepts are part of most formal historical research: Research is often conducted using the hourglass model structure of research. The hourglass model starts with a broad spectrum for research, focusing in on the required information through the method of the project (like the neck of the hourglass), then expands the research in the form of discussion and results. The major steps in conducting research are: The steps generally represent

9775-414: The following steps are usually part of most formal research, both basic and applied: A common misconception is that a hypothesis will be proven (see, rather, null hypothesis ). Generally, a hypothesis is used to make predictions that can be tested by observing the outcome of an experiment. If the outcome is inconsistent with the hypothesis, then the hypothesis is rejected (see falsifiability ). However, if

9890-403: The former requiring evidence beyond a reasonable doubt , the latter considering only which side has the preponderance of evidence , or whether the proposition is more likely true or false. The parts of a legal case that are not in controversy are known, in general, as the "facts of the case." Beyond any facts that are undisputed, a judge or jury is usually tasked with being a trier of fact for

10005-469: The humanities is historical research, which is embodied in historical method . Historians use primary sources and other evidence to systematically investigate a topic, and then to write histories in the form of accounts of the past. Other studies aim to merely examine the occurrence of behaviours in societies and communities, without particularly looking for reasons or motivations to explain these. These studies may be qualitative or quantitative, and can use

10120-402: The idea that different people or cultures perceive the world through different, incommensurable conceptual schemes , leading them to very different impressions about what is the case and what evidence is available. Theory-ladenness threatens to impede the role of evidence as neutral arbiter since these additional assumptions may favor some theories over others. It could thereby also undermine

10235-402: The implausible consequence that many of simple everyday-beliefs would be unjustified. The more common view is that all kinds of mental states, including stored beliefs that are currently unconscious, can act as evidence. It is sometimes argued that the possession of a mental state capable of justifying another is not sufficient for the justification to happen. The idea behind this line of thought

10350-426: The independent or dependent variables. Research in the humanities involves different methods such as for example hermeneutics and semiotics . Humanities scholars usually do not search for the ultimate correct answer to a question, but instead, explore the issues and details that surround it. Context is always important, and context can be social, historical, political, cultural, or ethnic. An example of research in

10465-404: The late 2000s. Peer review is a form of self-regulation by qualified members of a profession within the relevant field. Peer review methods are employed to maintain standards of quality, improve performance, and provide credibility. In academia, scholarly peer review is often used to determine an academic paper's suitability for publication. Usually, the peer review process involves experts in

10580-503: The nature of evidence. These attempts often proceed by starting with intuitions from one field or in relation to one theoretical role played by evidence and go on to generalize these intuitions, leading to a universal definition of evidence. One important intuition is that evidence is what justifies beliefs . This line of thought is usually followed in epistemology and tends to explain evidence in terms of private mental states, for example, as experiences, other beliefs or knowledge. This

10695-480: The original research is to produce new knowledge rather than present the existing knowledge in a new form (e.g., summarized or classified). Original research can take various forms, depending on the discipline it pertains to. In experimental work, it typically involves direct or indirect observation of the researched subject(s), e.g., in the laboratory or in the field, documents the methodology , results, and conclusions of an experiment or set of experiments, or offers

10810-400: The other issues of a case. Evidence and rules are used to decide questions of fact that are disputed, some of which may be determined by the legal burden of proof relevant to the case. Evidence in certain cases (e.g. capital crimes ) must be more compelling than in other situations (e.g. minor civil disputes), which drastically affects the quality and quantity of evidence necessary to decide

10925-451: The outcome is consistent with the hypothesis, the experiment is said to support the hypothesis. This careful language is used because researchers recognize that alternative hypotheses may also be consistent with the observations. In this sense, a hypothesis can never be proven, but rather only supported by surviving rounds of scientific testing and, eventually, becoming widely thought of as true. A useful hypothesis allows prediction and within

11040-423: The overall process; however, they should be viewed as an ever-changing iterative process rather than a fixed set of steps. Most research begins with a general statement of the problem, or rather, the purpose for engaging in the study. The literature review identifies flaws or holes in previous research which provides justification for the study. Often, a literature review is conducted in a given subject area before

11155-465: The purposes of deciding a particular case. Two primary burden-of-proof considerations exist in law. The first is on whom the burden rests. In many, especially Western, courts, the burden of proof is placed on the prosecution in criminal cases and the plaintiff in civil cases. The second consideration is the degree of certitude proof must reach, depending on both the quantity and quality of evidence. These degrees are different for criminal and civil cases,

11270-479: The relation between evidence and the proposition supported by it. The issue of the nature of the evidential relation concerns the question of what this relation has to be like in order for one thing to justify a belief or to confirm a hypothesis. Important theories in this field include the probabilistic approach , hypothetico-deductivism and the positive-instance approach . Probabilistic approaches , also referred to as Bayesian confirmation theory , explain

11385-446: The research process is to produce new knowledge or deepen understanding of a topic or issue. This process takes three main forms (although, as previously discussed, the boundaries between them may be obscure): There are two major types of empirical research design: qualitative research and quantitative research. Researchers choose qualitative or quantitative methods according to the nature of the research topic they want to investigate and

11500-571: The research profession. The word research is derived from the Middle French " recherche ", which means "to go about seeking", the term itself being derived from the Old French term "recerchier," a compound word from "re-" + "cerchier", or "sercher", meaning 'search'. The earliest recorded use of the term was in 1577. Research has been defined in a number of different ways, and while there are similarities, there does not appear to be

11615-697: The research questions they aim to answer: Qualitative research refers to much more subjective non-quantitative, use different methods of collecting data, analyzing data, interpreting data for meanings, definitions, characteristics, symbols metaphors of things. Qualitative research further classified into the following types: Ethnography: This research mainly focus on culture of group of people which includes share attributes, language, practices, structure, value, norms and material things, evaluate human lifestyle. Ethno: people, Grapho: to write, this disciple may include ethnic groups, ethno genesis, composition, resettlement and social welfare characteristics. Phenomenology : It

11730-459: The role of evidence is that it is what justifies beliefs . For example, Phoebe's auditory experience of the music justifies her belief that the speakers are on. Evidence has to be possessed by the believer in order to play this role. So Phoebe's own experiences can justify her own beliefs but not someone else's beliefs. Some philosophers hold that evidence possession is restricted to conscious mental states, for example, to sense data. This view has

11845-439: The same elite status as those of North America and Europe, because limitations on the availability of resources including high-quality paper and sophisticated image-rendering software and printing tools render these publications less able to satisfy standards currently carrying formal or informal authority in the publishing industry. These limitations in turn result in the under-representation of scholars from periphery nations among

11960-452: The same field who are consulted by editors to give a review of the scholarly works produced by a colleague of theirs from an unbiased and impartial point of view, and this is usually done free of charge. The tradition of peer reviews being done for free has however brought many pitfalls which are also indicative of why most peer reviewers decline many invitations to review. It was observed that publications from periphery countries rarely rise to

12075-430: The same vocabulary, i.e. use the same predicates, like " s w a n {\displaystyle swan} " or " w h i t e {\displaystyle white} " above. But many scientific theories posit theoretical objects, like electrons or strings in physics, that are not directly observable and therefore cannot show up in the evidence as conceived here. In scientific research evidence

12190-419: The sentence describes a positive instance of this statement. Understood in its broadest sense, evidence for a proposition is what supports this proposition. Traditionally, the term is sometimes understood in a narrower sense: as the intuitive knowledge of facts that are considered indubitable. In this sense, only the singular form is used. This meaning is found especially in phenomenology, in which evidence

12305-413: The set of publications holding prestige status relative to the quantity and quality of those scholars' research efforts, and this under-representation in turn results in disproportionately reduced acceptance of the results of their efforts as contributions to the body of knowledge available worldwide. The open access movement assumes that all information generally deemed useful should be free and belongs to

12420-421: The techniques and guidelines by which historians use historical sources and other evidence to research and then to write history. There are various history guidelines that are commonly used by historians in their work, under the headings of external criticism, internal criticism, and synthesis. This includes lower criticism and sensual criticism. Though items may vary depending on the subject matter and researcher,

12535-403: The term "evidence" in phenomenology shows many parallels to its epistemological usage, but it is understood in a narrower sense. Thus, evidence here specifically refers to intuitive knowledge, which is described as "self-given" ( selbst-gegeben ). This contrasts with empty intentions, in which one refers to states of affairs through a certain opinion, but without an intuitive presentation. This

12650-426: The term in 1904 so as to initiate "a broad new science" joining "traditional paleontology with the evidence and insights of geology and isotopic chemistry." On the other hand, Charles Doolittle Walcott , a Smithsonian adventurer, has been cited as the "founder of Precambrian paleobiology". Although best known as the discoverer of the mid- Cambrian Burgess shale animal fossils, in 1883 this American curator found

12765-402: The theory was true. It thereby explains the evidential relation between the experiment and the theory. One problem with this approach is that it cannot distinguish between relevant and certain irrelevant cases. So if smoke is evidence for the hypothesis "there is fire", then it is also evidence for conjunctions including this hypothesis, for example, "there is fire and Socrates was wise", despite

12880-634: The triannual Journal for Artistic Research ( JAR ), an international, online, open access , and peer-reviewed journal for the identification, publication, and dissemination of artistic research and its methodologies, from all arts disciplines and it runs the Research Catalogue (RC), a searchable, documentary database of artistic research, to which anyone can contribute. Patricia Leavy addresses eight arts-based research (ABR) genres: narrative inquiry, fiction-based research, poetry, music, dance, theatre, film, and visual art. In 2016,

12995-618: The two main categories of evidence presented at a trial or hearing. In the United States, evidence in federal court is admitted or excluded under the Federal Rules of Evidence . The burden of proof is the obligation of a party in an argument or dispute to provide sufficient evidence to shift the other party's or a third party's belief from their initial position. The burden of proof must be fulfilled by both establishing confirming evidence and negating oppositional evidence. Conclusions drawn from evidence may be subject to criticism based on

13110-418: The valid results of one study. Studies with a narrow scope can result in a lack of generalizability, meaning that the results may not be applicable to other populations or regions. In comparative politics, this can result from using a single-country study, rather than a study design that uses data from multiple countries. Despite the issue of generalizability, single-country studies have risen in prevalence since

13225-460: Was misleading since it was part of a simulated reality. This account of evidence and rationality can also be extended to other doxastic attitudes, like disbelief and suspension of belief. So rationality does not just demand that we believe something if we have decisive evidence for it, it also demands that we disbelieve something if we have decisive evidence against it and that we suspend belief if we lack decisive evidence either way. The meaning of
