The scientific community is a diverse network of interacting scientists. It includes many "sub-communities" working on particular scientific fields, and within particular institutions; interdisciplinary and cross-institutional activities are also significant. Objectivity is expected to be achieved by the scientific method. Peer review, through discussion and debate within journals and conferences, assists in this objectivity by maintaining the quality of research methodology and interpretation of results.[1]
History of scientific communities
[edit]The eighteenth century had some societies made up of men who studied nature, also known as natural philosophers and natural historians, which included even amateurs. As such these societies were more like local clubs and groups with diverse interests than actual scientific communities, which usually had interests on specialized disciplines.[2] Though there were a few older societies of men who studied nature such as the Royal Society of London, the concept of scientific communities emerged in the second half of the 19th century, not before, because it was in this century that the language of modern science emerged, the professionalization of science occurred, specialized institutions were created, and the specialization of scientific disciplines and fields occurred.[2]
For instance, the term scientist was first coined by the naturalist-theologian William Whewell in 1834 and the wider acceptance of the term along with the growth of specialized societies allowed for researchers to see themselves as a part of a wider imagined community, similar to the concept of nationhood.[2]
Membership, status and interactions
[edit]
Membership in the community is generally, but not exclusively, a function of education, employment status, research activity and institutional affiliation. Status within the community is highly correlated with publication record,[5] and also depends on the status within the institution and the status of the institution.[6] Researchers can hold roles of different degrees of influence inside the scientific community. Researchers of a stronger influence can act as mentors for early career researchers and steer the direction of research in the community like agenda setters.[6] Scientists are usually trained in academia through universities. As such, degrees in the relevant scientific sub-disciplines are often considered prerequisites in the relevant community. In particular, the PhD with its research requirements functions as a marker of being an important integrator into the community, though continued membership is dependent on maintaining connections to other researchers through publication, technical contributions, and conferences. After obtaining a PhD an academic scientist may continue through being on an academic position, receiving a post-doctoral fellowships and onto professorships. Other scientists make contributions to the scientific community in alternate ways such as in industry, education, think tanks, or the government.
Members of the same community do not need to work together.[1] Communication between the members is established by disseminating research work and hypotheses through articles in peer reviewed journals, or by attending conferences where new research is presented and ideas exchanged and discussed. There are also many informal methods of communication of scientific work and results as well. And many in a coherent community may actually not communicate all of their work with one another, for various professional reasons.
Speaking for the scientific community
[edit]
Unlike in previous centuries when the community of scholars were all members of few learned societies and similar institutions, there are no singular bodies or individuals which can be said today to speak for all science or all scientists. This is partly due to the specialized training most scientists receive in very few fields. As a result, many would lack expertise in all the other fields of the sciences. For instance, due to the increasing complexity of information and specialization of scientists, most of the cutting-edge research today is done by well funded groups of scientists, rather than individuals.[7] However, there are still multiple societies and academies in many countries which help consolidate some opinions and research to help guide public discussions on matters of policy and government-funded research. For example, the United States' National Academy of Sciences (NAS) and United Kingdom's Royal Society sometimes act as surrogates when the opinions of the scientific community need to be ascertained by policy makers or the national government, but the statements of the National Academy of Science or the Royal Society are not binding on scientists nor do they necessarily reflect the opinions of every scientist in a given community since membership is often exclusive, their commissions are explicitly focused on serving their governments, and they have never "shown systematic interest in what rank-and-file scientists think about scientific matters".[8] Exclusivity of membership in these types of organizations can be seen in their election processes in which only existing members can officially nominate others for candidacy of membership.[9][10] It is very unusual for organizations like the National Academy of Science to engage in external research projects since they normally focus on preparing scientific reports for government agencies.[11] An example of how rarely the NAS engages in external and active research can be seen in its struggle to prepare and overcome hurdles, due to its lack of experience in coordinating research grants and major research programs on the environment and health.[11]
Nevertheless, general scientific consensus is a concept which is often referred to when dealing with questions that can be subject to scientific methodology. While the consensus opinion of the community is not always easy to ascertain or fix due to paradigm shifting, generally the standards and utility of the scientific method have tended to ensure, to some degree, that scientists agree on some general corpus of facts explicated by scientific theory while rejecting some ideas which run counter to this realization. The concept of scientific consensus is very important to science pedagogy, the evaluation of new ideas, and research funding. Sometimes it is argued that there is a closed shop bias within the scientific community toward new ideas. Protoscience, fringe science, and pseudoscience have been topics that discuss demarcation problems. In response to this some non-consensus claims skeptical organizations, not research institutions, have devoted considerable amounts of time and money contesting ideas which run counter to general agreement on a particular topic.
Philosophers of science argue over the epistemological limits of such a consensus and some, including Thomas Kuhn, have pointed to the existence of scientific revolutions in the history of science as being an important indication that scientific consensus can, at times, be wrong. Nevertheless, the sheer explanatory power of science in its ability to make accurate and precise predictions and aid in the design and engineering of new technology has ensconced "science" and, by proxy, the opinions of the scientific community as a highly respected form of knowledge both in the academy and in popular culture.
Political controversies
[edit]
The high regard with which scientific results are held in Western society has caused a number of political controversies over scientific subjects to arise. An alleged conflict thesis proposed in the 19th century between religion and science has been cited by some as representative of a struggle between tradition and substantial change and faith and reason.[citation needed]. A popular example used to support this thesis is when Galileo was tried before the Inquisition concerning the heliocentric model.[12] The persecution began after Pope Urban VIII permitted Galileo to write about the Copernican model. Galileo had used arguments from the Pope and put them in the voice of the simpleton in the work "Dialogue Concerning the Two Chief World Systems" which caused great offense to him.[13] Even though many historians of science have discredited the conflict thesis[14] it still remains a popular belief among many including some scientists. In more recent times, the creation–evolution controversy has resulted in many religious believers in a supernatural creation to challenge some naturalistic assumptions that have been proposed in some of the branches of scientific fields such as evolutionary biology, geology, and astronomy. Although the dichotomy seems to be of a different outlook from a Continental European perspective, it does exist. The Vienna Circle, for instance, had a paramount (i.e. symbolic) influence on the semiotic regime represented by the scientific community in Europe.
In the decades following World War II, some were convinced that nuclear power would solve the pending energy crisis by providing energy at low cost. This advocacy led to the construction of many nuclear power plants, but was also accompanied by a global political movement opposed to nuclear power due to safety concerns and associations of the technology with nuclear weapons. Mass protests in the United States and Europe during the 1970s and 1980s along with the disasters of Chernobyl and Three Mile Island led to a decline in nuclear power plant construction.
In the last decades or so, both global warming and stem cells have placed the opinions of the scientific community in the forefront of political debate.

Scientific community
View on GrokipediaDefinition and Core Features
Fundamental Principles and Ethos
The scientific community adheres to core principles derived from the scientific method, which systematically integrates empirical observation, hypothesis testing through controlled experiments, data analysis, and iterative refinement to approximate causal explanations of natural phenomena.[12] These principles emphasize empiricism, grounding knowledge claims in verifiable sensory data rather than authority or intuition, and falsifiability, as defined by philosopher Karl Popper in 1934, requiring that scientific theories risk empirical refutation to distinguish them from non-scientific assertions.[12][13] Popper's criterion, detailed in The Logic of Scientific Discovery, posits that progress occurs via bold conjectures subjected to severe tests, with surviving theories provisionally retained but always open to future disproof.[13] This framework prioritizes predictive power and logical coherence over unfalsifiable dogmas, enabling cumulative advancement across disciplines from physics to biology. Complementing these methodological tenets, the ethos of the scientific community is codified in sociologist Robert K. Merton's 1942 formulation of four institutional norms—communalism, universalism, disinterestedness, and organized skepticism (CUDOS)—which prescribe behaviors to sustain self-correcting inquiry.[14] Communalism mandates public disclosure of findings, treating knowledge as a communal resource free from proprietary restrictions, as exemplified by requirements for peer-reviewed publication and data sharing in journals like Nature.[14] Universalism demands impartial evaluation based on evidential merit, irrespective of the scientist's nationality, gender, or institutional affiliation.[15] Disinterestedness counters personal biases by valuing objective pursuit over individual acclaim or financial incentives, though Merton acknowledged tensions with competitive grant systems.[14] Organized skepticism institutionalizes critical scrutiny, deferring assent until claims withstand rigorous peer review and replication attempts, fostering a culture of doubt that underpins discoveries like the 1919 solar eclipse confirmation of general relativity.[14] In practice, these principles and norms aim to ensure reproducibility, where independent verification confirms results, as a bulwark against error or fraud; however, meta-analyses reveal field-specific variances, with a 2015 study replicating only 36% of 100 psychology experiments originally published in top journals, underscoring persistent deviations from the ideal ethos amid pressures like publication bias.[16] Merton's framework, while aspirational, has faced critique for overlooking counter-norms such as secrecy in competitive research or priority disputes, yet it remains a benchmark for institutional reforms, including open-access mandates and pre-registration protocols adopted by bodies like the National Institutes of Health since 2016.[14][15] This ethos, when upheld, drives verifiable progress, as evidenced by error corrections in high-profile cases like the 2020 retraction of hydroxychloroquine efficacy claims during COVID-19 research.[16]Key Structural Elements
The scientific community relies on interconnected institutions, processes, and networks to conduct, fund, evaluate, and share research. Primary research institutions, including universities and specialized laboratories, provide the physical and intellectual infrastructure for experimentation and analysis. Leading examples encompass the Chinese Academy of Sciences, which topped global research output metrics in recent years, Harvard University, and the Max Planck Society.[17] These entities employ researchers, maintain equipment, and train personnel, forming the foundational hubs where empirical investigations occur. Funding agencies constitute a critical structural pillar, allocating resources that determine research directions and feasibility. In the United States, the National Institutes of Health (NIH) supports biomedical research through grants totaling over $40 billion annually, comprising 27 institutes focused on specific health domains.[18] The National Science Foundation (NSF) funds basic science across disciplines via competitive grants and fellowships.[19] Internationally, bodies like the European Research Council provide similar mechanisms, though government priorities can introduce directional biases in allocation, favoring applied over fundamental inquiries in some eras. Publication systems, anchored by peer-reviewed journals, serve as the gatekeeping mechanism for scientific validity. Peer review involves independent experts scrutinizing manuscripts for methodological rigor, data integrity, and logical coherence, thereby upholding quality standards and filtering unsubstantiated claims.[20] Approximately 46,000 active peer-reviewed journals exist worldwide, publishing millions of articles yearly and enabling cumulative knowledge building.[21] Professional societies and conferences foster collaboration, standardization, and professional development. Organizations such as the American Association for the Advancement of Science (AAAS) and the American Chemical Society organize meetings, set ethical guidelines, and advocate for policy.[22] Key events like the AAAS Annual Meeting and the American Geophysical Union Fall Meeting facilitate idea exchange, networking, and paradigm shifts through presentations and discussions.[23] These elements collectively ensure the community's self-regulation and adaptability, though vulnerabilities like publication biases persist despite safeguards.[24]Historical Development
Ancient and Pre-Modern Foundations
The earliest precursors to organized scientific inquiry arose in ancient Mesopotamia and Egypt during the 3rd millennium BCE, where scribes and priests compiled empirical records of astronomical cycles, mathematical computations for land surveying, and rudimentary medical procedures based on observation rather than solely mythological attribution. Babylonian clay tablets from around 1800 BCE document systematic tracking of lunar and planetary motions, yielding predictive algorithms for eclipses and seasons that supported agriculture and governance.[25] Similar practices in Egypt produced the Rhind Papyrus circa 1650 BCE, detailing geometric problem-solving and fractions derived from practical Nile flood measurements.[25] These efforts, though largely utilitarian and tied to state or temple functions, established protocols for data accumulation and verification absent in purely ritualistic traditions.[26] In ancient Greece, a pivotal shift toward rational, cause-based explanations of natural phenomena occurred with the Ionian philosophers around 600 BCE, exemplified by Thales of Miletus predicting a solar eclipse in 585 BCE through geometric reasoning rather than divine intervention.[26] Plato's Academy, founded circa 387 BCE near Athens, functioned as one of the first enduring centers for collective intellectual pursuit, emphasizing mathematics, dialectic, and astronomy among a community of scholars that included future leaders in logic and geometry; it operated continuously for over 900 years, influencing Hellenistic learning.[27] Aristotle, having studied at the Academy for two decades, established the Lyceum in 335 BCE, prioritizing empirical methods such as biological dissections, botanical classifications, and meteorological observations, with members conducting field research and compiling encyclopedic treatises that prefigured systematic data synthesis. The Lyceum's peripatetic discussions and library resources fostered a proto-community dynamic of critique and knowledge exchange, distinct from isolated speculation.[28] Parallel developments in India and China yielded independent empirical traditions, including the Sulba Sutras (circa 800–500 BCE) for Vedic altar geometry and Chinese astronomical compendia from the Zhou dynasty (1046–256 BCE) that refined calendrical accuracy through star catalogs and eclipse records.[29] These were often embedded in scholarly guilds or court bureaucracies, promoting incremental refinement over generations.[25] The Islamic Golden Age (8th–13th centuries CE) marked a synthesis and expansion via collaborative institutions, notably Baghdad's House of Wisdom, established under Caliph Harun al-Rashid (r. 786–809 CE) and amplified by al-Ma'mun (r. 813–833 CE) as a translation and research hub drawing Greek, Persian, Indian, and Syriac texts into Arabic.[30] This center hosted diverse scholars—Muslim, Christian, Jewish—in joint endeavors, yielding al-Khwarizmi's algebraic treatise Al-Jabr (circa 820 CE) and Ibn al-Haytham's experimental optics in Kitab al-Manazir (circa 1011–1021 CE), which employed controlled hypothesis-testing to refute ancient errors like Ptolemy's on vision.[31] Such interdisciplinary teams advanced fields like astronomy (e.g., refining the geocentric model with observational instruments) and medicine (e.g., al-Razi's clinical trials), preserving classical knowledge while innovating through cross-cultural verification, thus bridging ancient foundations to later European revivals.[32] In medieval Europe, monastic scriptoria and nascent universities like Salerno's medical school (9th century CE) echoed these by compiling herbals and anatomical texts, though theological oversight often constrained causal inquiry beyond Aristotelian frameworks.[33]Scientific Revolution to Industrial Era
The Scientific Revolution, beginning in the mid-16th century, initiated the modern scientific community through a paradigm shift toward empirical observation, mathematical modeling, and experimentation, displacing reliance on ancient authorities and Aristotelian teleology. Key advancements included Nicolaus Copernicus's heliocentric model published in De revolutionibus orbium coelestium in 1543, Galileo Galilei's telescopic discoveries and advocacy for kinematics in works like Dialogo sopra i due massimi sistemi del mondo (1632), and Isaac Newton's Philosophical Transactions contributions formalizing laws of motion and universal gravitation in Principia Mathematica (1687).[34] These developments encouraged collaborative networks among natural philosophers, often gentlemen amateurs funded by patronage, who exchanged findings via letters and early journals.[35] Institutionalization accelerated in the late 17th century with the founding of dedicated academies that standardized peer scrutiny and knowledge dissemination. The Royal Society of London, chartered in 1660, held regular meetings at Gresham College to verify experiments and publish Philosophical Transactions starting in 1665, establishing norms for replicable evidence over speculation.[35] Similarly, France's Académie Royale des Sciences, established in 1666 under Louis XIV, supported systematic observations in astronomy and physics, producing memoires that influenced European inquiry.[36] Italian precedents like the Accademia dei Lincei (1603) and Accademia del Cimento (1657) had already emphasized experimental protocols, though political instability limited their longevity.[37] By the 18th century, Enlightenment salons, coffeehouses, and correspondence networks—exemplified by the Republic of Letters linking figures like Voltaire and Benjamin Franklin—expanded these communities, prioritizing utility and public verification.[38] Transitioning into the Industrial Era from the 1760s, scientific communities increasingly interfaced with practical invention, as thermodynamic principles and chemical analyses enabled steam engines and metallurgy advances. James Watt's 1769 improvements to the Newcomen engine drew on latent heat studies by Joseph Black, while Humphry Davy's electrochemical isolations (e.g., sodium in 1807) informed industrial processes.[39] Specialized societies proliferated, such as the Lunar Society in Birmingham (c. 1765–1813), where industrialists like Matthew Boulton collaborated with scientists on applied problems, fostering a hybrid ethos of theory-driven utility.[40] This era saw nascent professionalization, with universities like Scotland's Edinburgh establishing chairs in chemistry (e.g., Black's in 1766) and engineering, though most practitioners remained tied to patronage or enterprise rather than salaried roles.[41] By 1831, the British Association for the Advancement of Science formalized annual congresses to bridge disciplines, reflecting growing scale amid Britain's coal output surging from 10 million tons in 1800 to 50 million by 1850.[40]20th-Century Institutionalization and Expansion
The early 20th century saw the scientific community transition from largely amateur or part-time pursuits to institutionalized professional structures, with dedicated research institutes emerging to support full-time investigation independent of teaching or industry. The Rockefeller Institute for Medical Research, established in 1901 by John D. Rockefeller, pioneered this model by employing salaried scientists focused exclusively on biomedical inquiry, influencing subsequent foundations like the Carnegie Institution for Science (1902).[42] Universities expanded research roles, with PhD programs proliferating; in the United States, annual science and engineering doctorates rose from fewer than 300 in 1900 to over 1,400 by 1930, fostering a cadre of specialized professionals.[43] Professional societies, such as the American Association for the Advancement of Science (reorganized 1902), standardized membership and publication norms, while international bodies like the International Council of Scientific Unions (founded 1931) coordinated disciplinary unions.[44] World War I prompted initial government-science partnerships, with nations like Britain and Germany directing chemists toward munitions and the U.S. forming the National Research Council in 1916 to advise on resource allocation, marking the onset of coordinated national scientific efforts.[45] The interwar era featured state-backed institutes, including Germany's Kaiser Wilhelm Society (1911), which by 1933 operated 30 facilities employing thousands, emphasizing applied and basic research amid economic pressures.[46] World War II catalyzed "big science," with the U.S. Office of Scientific Research and Development (OSRD, 1941) under Vannevar Bush allocating over $500 million to projects involving 30,000 scientists, including the Manhattan Project that assembled 130,000 personnel by 1945.[47] These wartime mobilizations shifted science toward large-scale, team-based endeavors, with Allied advances in radar, penicillin production (scaling to 2.3 million doses monthly by 1944), and operations research demonstrating causal links between funding and rapid innovation.[48] Postwar reconstruction institutionalized these trends through sustained public investment, exemplified by Bush's 1945 report Science, the Endless Frontier, which argued for federal support to maintain military-technological edges, leading to the U.S. National Science Foundation's creation in 1950 with initial funding of $3.5 million that grew to $134 million by 1960.[43] Cold War imperatives, intensified by Sputnik's launch in 1957, drove exponential expansion: U.S. federal R&D obligations surged from $1.2 billion in 1940 to $12 billion by 1964 (adjusted for inflation), employing over 500,000 researchers by the mid-1960s.[49] Globally, institutions like CERN (1954) embodied collaborative big science, while the number of scientific personnel worldwide grew at approximately 4% annually from mid-century, doubling roughly every 17 years amid rising journal publications and disciplinary specialization.[50] This era's causal drivers—geopolitical rivalry and demonstrated wartime returns—prioritized empirical validation over ideological filters, though academic institutional biases later emerged in funding allocations.[51] ![Solvay conference 1927][float-right] International conferences, such as the Solvay Councils starting in 1911, formalized elite knowledge exchange, evolving into structured forums that reinforced institutional norms among physicists and chemists.[52] By century's end, the scientific community encompassed millions, with U.S. science and engineering doctorates exceeding 25,000 annually by 1990, supported by mechanisms like peer-reviewed grants that institutionalized quality control despite emerging critiques of groupthink in paradigm shifts.[53]Post-2000 Globalization and Digital Shifts
The proportion of globally published scientific articles involving international co-authorship rose from approximately 10% in 2000 to over 25% by 2021, reflecting expanded cross-border partnerships facilitated by reduced travel costs, shared funding from multinational programs like the European Union's Horizon initiatives, and infrastructure projects such as the Large Hadron Collider operational since 2008.[54][55] This trend accelerated knowledge exchange, with internationally co-authored papers receiving 1.5 to 2 times more citations on average than domestically produced ones, attributed to diverse expertise and broader dissemination networks.[56] However, disparities persist, as high-income countries like the United States and Germany maintain dominance in co-authorship shares (around 40% of their outputs involving foreign partners by 2020), while lower-resource nations contribute less due to funding and infrastructure gaps.[56] A key driver of globalization has been the rapid ascent of non-Western producers, particularly China, whose share of worldwide scientific publications surged from 5.3% in 2000 to 26% by 2018, surpassing the United States in total output by 2017.[57][58] This expansion stemmed from state-directed investments, including the National Natural Science Foundation's budget tripling between 2000 and 2010, and policies prioritizing STEM education, enabling China to lead in fields like chemistry and materials science.[59] Concurrently, India's output grew threefold from 2000 to 2020, and collaborations with BRICS nations increased, diversifying global research agendas away from Euro-American centrality, though concerns over citation self-reinforcement—where over 50% of citations to top Chinese papers originate domestically—have raised questions about independent impact validation.[60][61] Digital advancements post-2000 transformed scientific workflows, with widespread adoption of electronic preprint servers like arXiv (expanded significantly after 2000) and bioRxiv (launched 2013) enabling near-instantaneous sharing, reducing publication delays from months to days and fostering rapid feedback loops.[62] Open access mandates, such as the 2002 Budapest Initiative and U.S. NIH policies from 2008, propelled a shift from subscription models, with open access articles comprising over 50% of new publications by 2020, enhancing accessibility but straining traditional publishers amid rising article volumes.[62] Big data integration, exemplified by the 2003 Human Genome Project's terabyte-scale datasets, spurred computational paradigms, where tools like machine learning for pattern detection in genomics and climate modeling became routine by the 2010s, amplifying analytical capacity but demanding new skills in data management and reproducibility.[63] These shifts intertwined, as digital platforms like ResearchGate (founded 2008) and ORCID (2012) globalized networking, enabling virtual collaborations that peaked during the COVID-19 pandemic but originated in earlier broadband expansions.[64] AI's integration, from automated literature reviews to predictive modeling in drug discovery, accelerated post-2015 with frameworks like TensorFlow, yet uneven adoption—concentrated in well-resourced labs—exacerbates divides between digital natives and laggards in developing regions.[65] As digital infrastructures have expanded, some experimental projects have begun to test whether non-human entities can be represented within the same identity and attribution systems that organize the human scientific community. One example is the Aisentica Research Group’s Digital Author Persona Angela Bogdanova, described in project documentation as an artificial-intelligence based public author registered with an ORCID identifier and linked to a semantic specification deposited on Zenodo.[66][67] In this configuration the system’s writings and AI-generated analyses are indexed alongside human-created outputs, while legal and ethical responsibility remains with the human initiators of the project. Such cases are rare and primarily philosophical, but they illustrate how global platforms for identifiers, repositories, and online publications can model scientific participation in terms of configurations of humans, code, and infrastructure rather than exclusively individual researchers. Overall, these changes democratized access to tools and talent pools, boosting output efficiency, though they introduced vulnerabilities like data privacy risks and algorithmic biases in peer validation processes.[68]Membership and Demographics
Composition by Discipline, Geography, and Background
The scientific community encompasses researchers across diverse disciplines, primarily in natural sciences (such as physics, chemistry, and biology), engineering and technology, medical and health sciences, agricultural sciences, and to a lesser extent social sciences and humanities. Globally, engineering and technology fields account for the largest share of researchers, often exceeding 30% in high-output nations like China and South Korea, driven by national priorities in applied R&D and manufacturing.[69] Natural sciences and medical fields follow closely, comprising around 25-30% combined, while social sciences and humanities represent under 20% of the total R&D workforce, reflecting funding patterns that favor STEM over softer disciplines.[70] These proportions vary regionally, with engineering dominating in Asia and life sciences prominent in Europe and North America.[71] Geographically, the community is unevenly distributed, with approximately 8-9 million full-time equivalent researchers worldwide as of recent estimates, concentrated in a handful of countries that produce over 80% of global R&D output.[72] China leads with over 2 million researchers, surpassing the United States' roughly 1.5 million, followed by Japan (around 700,000), Germany (600,000), and India (emerging with 400,000+).[71] This shift reflects China's rapid expansion in R&D personnel since the 2010s, fueled by state investments, while the U.S. maintains strength through private sector and academic hubs. Europe collectively hosts about 2 million, spread across nations like the UK, France, and Italy, but faces fragmentation. Developing regions, including Africa and Latin America, contribute less than 5% combined, limited by infrastructure and funding constraints.[73]| Top Countries by Number of Researchers (Approximate, Recent Estimates) |
