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 typical normal human fetal cell will divide between 50 and 70 times before experiencing senescence. As the cell divides, the telomeres on the ends of chromosomes shorten. The Hayflick limit is the limit on cell replication imposed by the shortening of telomeres with each division. This end stage is known as cellular senescence.
An alternative view is that it is premature to conclude that HARKing has contributed to the replication crisis. [7] [5] [14] The preregistration of research hypotheses prior to data collection has been proposed as a method of identifying and deterring HARKing. However, the use of preregistration to prevent HARKing is controversial. [3]
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.
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 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]

The replication crisis is an ongoing methodological crisis in which it has been found that many scientific studies are difficult or impossible to replicate. [ 25 ] [ 26 ] While the crisis has its roots in the meta-research of the mid- to late 20th century, the phrase "replication crisis" was not coined until the early 2010s [ 27 ] as part of a ...
