The Distribution of P-values in Medical Research Articles Suggested Selective Reporting Associated with Statistical Significance
Published P-values provide a window into the global enterprise of medical research. The aim of this study was to use the distribution of published P-values to estimate the relative frequencies of null and alternative hypotheses and to seek irregularities suggestive of publication bias.
A Simple Explanation for the Replication Crisis in Science
The replication crisis in science is largely attributable to a mismatch in our expectations of how often findings should replicate and how difficult it is to actually discover true findings in certain fields.
The persistence of poor methods results partly from incentives that favor them, leading to the natural selection of bad science. This dynamic requires no conscious strategizing - no deliberate cheating nor loafing - by scientists, only that publication is a principle factor for career advancement.
