The authors evaluate the quality of research reported in major journals in social-personality psychology by ranking those journals with respect to their N-pact Factors (NF)—the statistical power of the empirical studies they publish to detect typical …

This crowdsourced project introduces a collaborative approach to improving the reproducibility of scientific research, in which findings are replicated in qualified independent laboratories before (rather than after) they are published. Our goal is …

Sharing data, materials, and analysis scripts with reviewers and readers is valued in psychological science. To facilitate this sharing, files should be stored in a stable location, referenced with unique identifiers, and cited in published work …

Null hypothesis testing of correlational predictions from weak substantive theories in soft psychology is subject to the influence of ten obfuscating factors whose effects are usually (1) sizeable, (2) opposed, (3) variable, and (4) unknown. The net …

Recently, many psychological effects have been surprisingly difficult to reproduce. This article asks why, and investigates whether conceptually replicating an effect in the original publication is related to the success of independent, direct …

Null hypothesis testing as a tool in research is defended. Six examples are offered of situations in which, if all the researcher could do was "reject H₀ at α = .05" the scientific contribution would still be substantial. The examples are drawn from …

Psychological scientists have recently started to reconsider the importance of close replications in building a cumulative knowledge base; however, there is no consensus about what constitutes a convincing close replication study. To facilitate …

Crisis of replicability is one term that psychological scientists use for the current introspective phase we are in—I argue instead that we are going through a revolution analogous to a political revolution. Revolution 2.0 is an uprising focused on …

In this article, we propose analytic review (AR) as a solution to the problem of misreporting statistical results in psychological science. AR requires authors submitting manuscripts for publication to also submit the data file and syntax used during …

The Publication Manual of the American Psychological Association (American Psychological Association, 2001, 2010) calls for the reporting of effect sizes and their confidence intervals. Estimates of effect size are useful for determining the …
