This led prominent scholars to declare a "crisis of confidence" in psychology and other fields, [42] and the ensuing situation came to be known as the "replication crisis". Although the beginning of the replication crisis can be traced to the early 2010s, some authors point out that concerns about replicability and research practices in the ...
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 ...
It finds that the majority of the replication concern the medical and social sciences (especially, psychology and behavioral economics) and that there is for now no standardized evaluation criteria: "methods of assessing replicability are inconsistent and the replicability percentages depend strongly on the methods used."
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 examples that the sociologists cite in their paper is that of the Open Science Grid, which enables the development of large-scale projects that require high-volume data management and processing, which is accomplished through a distributed computer network. Moreover, the grid provides the necessary tools that the scientists can use to ...
Example of direct replication and conceptual replication There are two main types of replication in statistics. First, there is a type called “exact replication” (also called "direct replication"), which involves repeating the study as closely as possible to the original to see whether the original results can be precisely reproduced.
