Reproducibility and Replicability Knowledge

A Powerful Nudge? Presenting Calculable Consequences of Underpowered Research Shifts Incentives Toward Adequately Powered Designs

If psychologists have recognized the pitfalls of underpowered research for decades, why does it persist? Incentives, perhaps: underpowered research benefits researchers individually (increased productivity), but harms science collectively (inflated …

A recipe for extremely reproducible enrichment analysis (and why we need it)

Unreliable and irreproducible research is a significant problem that wastes resources and risks undermining the public perception of science. Previous work has highlighted that published enrichment analyses frequently suffer from statistical and …

A Reliability-Generalization Study of Journal Peer Reviews: A Multilevel Meta-Analysis of Inter-Rater Reliability and Its Determinants

Background: This paper presents the first meta-analysis for the inter-rater reliability (IRR) of journal peer reviews. IRR is defined as the extent to which two or more independent reviews of the same scientific document agree. Methodology/Principal …

A Short (Personal) Future History of Revolution 2.0

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 …

A Social Priming Data Set With Troubling Oddities

A recent paper by Chatterjee, Rose, and Sinha (2013) reported impressively large “money priming” effects: incidental exposure to concepts relating to cash or credit cards made participants much less generous with their time and money (after cash …

A tale of two papers

An abstract about transparency and robustness for two papers

A Unified Framework to Quantify the Credibility of Scientific Findings

Societies invest in scientific studies to better understand the world and attempt to harness such improved understanding to address pressing societal problems. Published research, however, can be useful for theory or application only if it is …

A Vast Graveyard of Undead Theories: Publication Bias and Psychological Science’s Aversion to the Null

Publication bias remains a controversial issue in psychological science. The tendency of psychological science to avoid publishing null results produces a situation that limits the replicability assumption of science, as replication cannot be …

Academic Research in the 21st Century: Maintaining Scientific Integrity in a Climate of Perverse Incentives and Hypercompetition

Over the last 50 years, we argue that incentives for academic scientists have become increasingly perverse in terms of competition for research funding, development of quantitative metrics to measure performance, and a changing business model for …

Adapting open science and pre-registration to longitudinal research

Open science practices, such as pre-registration and data sharing, increase transparency and may improve the replicability of developmental science. However, developmental science has lagged behind other fields in implementing open science practices. …
