This article introduces a new approach for evaluating replication results. It combines effect-size estimation with hypothesis testing, assessing the extent to which the replication results are consistent with an effect size big enough to have been …
The syntax or codes used to fit Structural Equation Models (SEMs) convey valuable information on model specifications and the manner in which SEMs are estimated. We requested SEM syntaxes from a random sample of 229 articles (published in 1998–2013) …
One year after publishing "False-Positive Psychology," we propose a simple implementation of disclosure that requires but 21 words to achieve full transparency. This article is written in a casual tone. It includes phone-taken pictures of milk-jars …
Empirical research inevitably includes constructing a data set by processing raw data into a form ready for statistical analysis. Data processing often involves choices among several reasonable options for excluding, transforming, and coding data. We …
A number of scholars recently have argued for fundamental changes in the way psychological scientists conduct and report research. The behavior of researchers is influenced partially by incentive structures built into the manuscript evaluation …

The past several years have been a time for soul searching in psychology, as we have gradually come to grips with the reality that some of our cherished findings are less robust than we had assumed. Nevertheless, the replication crisis highlights the …
Most discussions of rigor and replication focus on empirical practices (methods used to collect and analyze data). Typically overlooked is the role of conceptual practices: the methods scientists use to arrive at and articulate research hypotheses in …
