Proteus Phenomenon
The Proteus phenomenon is the tendency in science for early replications of a work to contradict the original findings, a consequence of publication bias. It is akin to the winner's curse. The term was coined by John Ioannidis and Thomas A. Trikalinos in 2005 named after the Greek god Proteus who could rapidly change his appearance. A 2013 paper argued that the phenomenon might be "desirable or even optimal" from a scientific standpoint.

Science
Science is a systematic endeavor that builds and organizes knowledge in the form of testable explanations and predictions about the universe. Science may be as old as the human species, and some of the earliest archeological evidence for scientific reasoning is tens of thousands of years old. The earliest written records in the history of science come from Ancient Egypt and Mesopotamia in around 3000 to 1200 BCE. Their contributions to mathematics, astronomy, and medicine entered and shaped Greek natural philosophy of classical antiquity, whereby formal attempts were made to provide explanations of events in the physical world based on natural causes. After the fall of the Western Roman Empire, knowledge of Greek conceptions of the world deteriorated in Western Europe during the early centuries (400 to 1000 CE) of the Middle Ages, but was preserved in the Muslim world during the Islamic Golden Age and later by the efforts of Byzantine Greek scholars who brought Greek ...

Replication (scientific Method)
Reproducibility, also known as replicability and repeatability, is a major principle underpinning the scientific method. For the findings of a study to be reproducible means that results obtained by an experiment or an observational study or in a statistical analysis of a data set should be achieved again with a high degree of reliability when the study is replicated. There are different kinds of replication but typically replication studies involve different researchers using the same methodology. Only after one or several such successful replications should a result be recognized as scientific knowledge. With a narrower scope, ''reproducibility'' has been introduced in computational sciences: Any results should be documented by making all data and code available in such a way that the computations can be executed again with identical results. In recent decades, there has been a rising concern that many published scientific results fail the test of reproducibility, evoking a rep ...

Publication Bias
In published academic research, publication bias occurs when the outcome of an experiment or research study biases the decision to publish or otherwise distribute it. Publishing only results that show a significant finding disturbs the balance of findings in favor of positive results. The study of publication bias is an important topic in metascience. Despite similar quality of execution and design, papers with statistically significant results are three times more likely to be published than those with null results. This unduly motivates researchers to manipulate their practices to ensure statistically significant results, such as by data dredging. Many factors contribute to publication bias. For instance, once a scientific finding is well established, it may become newsworthy to publish reliable papers that fail to reject the null hypothesis. Most commonly, investigators simply decline to submit results, leading to non-response bias. Investigators may also assume they made a ...

Proteus
In Greek mythology, Proteus (; Ancient Greek: Πρωτεύς, ''Prōteus'') is an early prophetic sea-god or god of rivers and oceanic bodies of water, one of several deities whom Homer calls the "Old Man of the Sea" ''(hálios gérôn)''. Some who ascribe a specific domain to Proteus call him the god of "elusive sea change", which suggests the constantly changing nature of the sea or the liquid quality of water. He can foretell the future, but, in a mytheme familiar to several cultures, will change his shape to avoid doing so; he answers only to those who are capable of capturing him. From this feature of Proteus comes the adjective protean, meaning "versatile", "mutable", or "capable of assuming many forms". "Protean" has positive connotations of flexibility, versatility and adaptability. Name origin Proteus' name suggests the "first" (from Greek "πρῶτος" ''prōtos'', "first"), as ''prōtogonos'' (πρωτόγονος) is the "primordial" or the "firstborn". It is ...

Journal Of Clinical Epidemiology
The ''Journal of Clinical Epidemiology'' is a peer-reviewed journal of epidemiology. The journal was originally established as the ''Journal of Chronic Diseases'' in 1955 as a follow-up to Harry S. Truman's 1951 Presidential Task Force on national health concerns and the subsequently written Magnuson Report. Under the editorial leadership of Alvan Feinstein and Walter O. Spitzer, the title of the journal was changed to the ''Journal of Clinical Epidemiology'' with the January 1988 issue. The current editors are André Knottnerus (Netherlands School of Primary Care Research) and Peter Tugwell (University of Ottawa). According to the ''Journal Citation Reports'', the journal has a 2020 Impact Factor The impact factor (IF) or journal impact factor (JIF) of an academic journal is a scientometric index calculated by Clarivate that reflects the yearly mean number of citations of articles published in the last two years in a given journal, as i ... of 6.437, ranking it 5th out of ...

Reproducibility Project
The Reproducibility Project: Psychology was a Crowdsourced psychological science, crowdsourced collaboration of 270 contributing authors to repeat 100 published experimental and correlational psychological studies. This project was led by the Center for Open Science and its co-founder, Brian Nosek, who started the project in November 2011. The results of this collaboration were published in August 2015. Reproducibility is the ability to produce the same findings, using the same methodologies as the original work, but on a different dataset (for instance, collected from a different set of participants). The project has illustrated the growing problem of failed reproducibility in social science. This project has started a movement that has spread through the science world with the expanded testing of the reproducibility of published works. Results Brian Nosek of University of Virginia and colleagues sought out to replicate 100 different studies that all were published in 2008. The pr ...

Metascience
Metascience (also known as meta-research) is the use of scientific methodology to study science itself. Metascience seeks to increase the quality of scientific research while reducing inefficiency. It is also known as "''research on research''" and "''the science of science''", as it uses research methods to study how research is done and find where improvements can be made. Metascience concerns itself with all fields of research and has been described as "a bird's eye view of science". In the words of John Ioannidis, "Science is the best thing that has happened to human beings ... but we can do it better." In 1966, an early meta-research paper examined the statistical methods of 295 papers published in ten high-profile medical journals. It found that "in almost 73% of the reports read ... conclusions were drawn when the justification for these conclusions was invalid." Meta-research in the following decades found many methodological flaws, inefficiencies, and poor practices in r ...
