The replication crisis [a] is an ongoing methodological crisis in which the results of many scientific studies are difficult or impossible to reproduce. Because the reproducibility of empirical results is an essential part of the scientific method , [ 2 ] such failures undermine the credibility of theories building on them and potentially call ...
The project has brought attention to the replication crisis, and has contributed to shifts in scientific culture and publishing practices to address it. [3] The project was led by the Center for Open Science and its co-founder, Brian Nosek, who started the project in November 2011. [4]
Reproducibility, closely related to 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.
The replication crisis (or credibility crisis) is a methodological crisis in science that researchers began to acknowledge around the 2010s. The controversy revolves around the lack of reproducibility of many scientific findings, including those in psychology (e.g., among 100 studies, less than 50% of the findings were replicated).
The growth of metascience and the recognition of a scientific replication crisis have bolstered the paper's credibility, and led to calls for methodological reforms in scientific research. [8] [9] In commentaries and technical responses, statisticians Goodman and Greenland identified several weaknesses in Ioannidis' model.
In the Problem of science (2021), Rufus Barker Bausell argues that all disciplines, including the social sciences, currently face similar issues to medicine and physical sciences: "The problem, which has come to be known as the reproducibility crisis, affects almost all of science, not one or two individual disciplines."
Klimen is a vocal advocate for addressing the replication crisis in science. [8] She cites several concerning statistics about the reproducibility of scientific experiments and the prevalence of fabricated or plagiarized research papers: A 2016 report in Nature showed that 70% of researchers tried and failed to reproduce another scientist's ...
Replication (scientific method), one of the main principles of the scientific method, a.k.a. reproducibility Replication (statistics), the repetition of a test or complete experiment; Replication crisis; Self-replication, the process in which an entity (a cell, virus, program, etc.) makes a copy of itself
