In this deep dive session, Amanda Montoya (UCLA) and Karen Rambo-Hernandez (Texas A&M University) introduce the basics of preregistration and Registered Reports: two methods for creating a permanent record of a research plan prior to conducting data …
In this deep dive session, we introduce the basics of pre-registration: a method for creating a permanent record of a research plan prior to conducting data collection and/or data analysis. We discuss the conceptual similarities and practical …
This cross-sectional study examines discrepancies between registered protocols and subsequent publications for drug and diet trials whose findings were published in prominent clinical journals in the last decade. ClinicalTrials.gov was established in …
Objectives To identify and appraise empirical studies on publication and related biases published since 1998; to assess methods to deal with publication and related biases; and to examine, in a random sample of published systematic reviews, measures …
Scholars assert that pre-analysis plans (PAPs) generate boring, lab-report style papers and thus hamper publication. We test this claim by comparing the publication rates of experimental NBER working papers with and without PAPs. We find that …
Preregistration entails researchers registering their planned research hypotheses, methods, and analyses in a time-stamped document before they undertake their data collection and analyses. This document is then made available with the published …
Registered Reports (RRs) is a publishing model in which initial peer review is conducted prior to knowing the outcomes of the research. In-principle acceptance of papers at this review stage combats publication bias, and provides a clear distinction …
Preregistration requires scientists to describe the planned research activities before their project begins. Preregistration improves transparency in empirical research and is an institutional response to scientific misconduct. This paper studies the …
Preregistration has been proposed as a useful method for making a publicly verifiable distinction between confirmatory hypothesis tests, which involve planned tests of ante hoc hypotheses, and exploratory hypothesis tests, which involve unplanned …
In recent years, the discipline of political science has experienced demands and moves toward greater research transparency. While in quantitative research increased transparency through replication has become a fairly accepted convention, in …
