The idea for the registration of observational epidemiologic studies (with their protocols, hypotheses, and analysis plans) is modeled on the registration of randomized clinical trials (RCTs). The movement that led to the registration of RCTs was fed …

This is a commentary on Lee et al.’s (2019) article encouraging preregistration of model development, fitting, and evaluation. While we are in general agreement with Lee et al.’s characterization of the modeling process, we disagree on whether …

A recent workshop focused on the idea that protocols for nonrandomized studies should be registered in advance of their conduct. In reviewing the workshop report and publications citing it, I note a number of unfounded assumptions and little …

Replication has received increasing attention over the last decade. This comes on the heels of prominent instances of data fabrication (National Academies of Sciences, Engineering, and Medicine, 2017) and estimates that few studies attempt to …

Discussions around transparency in open science focus primarily on sharing data, materials, and coding schemes, especially as these practices relate to reproducibility. This fairly quantitative perspective of transparency does not align with all …

In an attempt to increase the reliability of empirical findings, psychological scientists have recently proposed a number of changes in the practice of experimental psychology. Most current reform efforts have focused on the analysis of data and the …

There is an ongoing debate regarding preregistration of epidemiologic study protocols. We examine the basic idea that preregistration of study protocols and their associated hypotheses would enhance the reliability of observational research. We …

Current attempts at methodological reform in sciences come in response to an overall lack of rigor in methodological and scientific practices in experimental sciences. However, most methodological reform attempts suffer from similar mistakes and …

Kerr ([1998]) coined the term ‘HARKing’ to refer to the practice of ‘hypothesizing after the results are known’. This questionable research practice has received increased attention in recent years because it is thought to have contributed to low …

I discuss Van Drimmelen’s (2023) Metascience2023 presentation on researchers’ decision making during the research process. In particular, I consider his evidence that researchers’ discretion over research decisions is unavoidable when they follow …
