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 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).
Brian Nosek of University of Virginia and colleagues sought out to replicate 100 different studies, all published in 2008. [5] The project pulled these studies from three different journals, Psychological Science, the Journal of Personality and Social Psychology, and the Journal of Experimental Psychology: Learning, Memory, and Cognition, published in 2008 to see if they could get the same ...
Despite skepticism about extreme statements made in the paper, Ioannidis's broader argument and warnings have been accepted by a large number of researchers. [7] 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.
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.
Amongst the issues about which Witkowski is most concerned are the quality, utility and validity of much of the research being published nowadays; the ‘replication crisis’; the efficacy of many psychotherapeutic practices that psychologists seem willing to embrace; and the failure of psychologists to mount a sufficiently strong challenge to ...
The Federal Aviation Administration issued temporary flight restrictions prohibiting drone flights over parts of New Jersey following an influx of sightings in recent weeks.. The notice, which ...
