Replication Research

 

The pipeline project: Pre-publication independent replications of a single laboratory's research pipeline

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 …

Using OSF to Share Data: A Step-by-Step Guide

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 …

Why Summaries of Research on Psychological Theories are Often Uninterpretable

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 …

Internal conceptual replications do not increase independent replication success

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 …

The Replication Recipe: What makes for a convincing replication?

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 …

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 …

Analytic Review as a Solution to the Misreporting of Statistical Results in Psychological Science

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 …

False-Positive Psychology: Undisclosed Flexibility in Data Collection and Analysis Allows Presenting Anything as Significant

In this article, we accomplish two things. First, we show that despite empirical psychologists’ nominal endorsement of a low rate of false-positive findings (≤ .05), flexibility in data collection, analysis, and reporting dramatically increases …

On the reproducibility of meta-analyses: six practical recommendations

Background: Meta-analyses play an important role in cumulative science by combining information across multiple studies and attempting to provide effect size estimates corrected for publication bias. Research on the reproducibility of meta-analyses …

Publication Prejudices: An Experimental Study of Confirmatory Bias in the Peer Review System

Confirmatory bias is the tendency to emphasize and believe experiences which support one's views and to ignore or discredit those which do not. The effects of this tendency have been repeatedly documented in clinical research. However, its …
