The editors of the Journal of Advanced Academics comment on Makel (2014). The replicability crisis in psychology is summarized in terms of three focal issues: the “file drawer” problem, lack of replication studies, and the null hypothesis …
The current crisis in scientific psychology about whether our findings are irreproducible was presaged years ago by Tversky and Kahneman (1971), who noted that even sophisticated researchers believe in the fallacious Law of Small Numbers—erroneous …
Context Most medical interventions have modest effects, but occasionally some clinical trials may find very large effects for benefits or harms. Objective To evaluate the frequency and features of very large effects in medicine. Data Sources Cochrane …
This article describes a systematic analysis of the relationship between empirical data and theoretical conclusions for a set of experimental psychology articles published in the journal Science between 2005–2012. When the success rate of a set of …
The last ten years have witnessed increasing awareness of questionable research practices (QRPs) in the life sciences [1,2], including p-hacking [3], HARKing [4], lack of replication [5], publication bias [6], low statistical power [7] and lack of …
Genetics and neuroscience are two areas of science that pose particular methodological problems because they involve detecting weak signals (i.e., small effects) in noisy data. In recent years, increasing numbers of studies have attempted to bridge …
Open science practices including open access (OA) publication, open methods, study preregistration, and open data are gaining acceptance across diverse fields of research. These practices are promoted as strategies to improve the reproducibility of …
