Confirmation through competent replication is a founding principle of modern science. However, biomedical researchers are rewarded for innovation, and not for confirmation, and confirmatory research is often stigmatized as unoriginal and as a …
The recent so-called crisis of replication continues to dominate psychology’s methodological landscape. It is argued here that the apparent renaissance of Popperian thinking that characterises some of the key responses to the crisis of replication is …
Efforts to replicate portions of the scientific literature have lead to widely varying and often low rates of replicability. This has raised concerns over a ``replication crisis'' whereby many of the statistically significant claims in the published …

The older adult population in the U.S. is becoming increasingly diverse across a constellation of factors including ethnoracial group, socioeconomic status, and immigration status. However, our understanding of the consequences of this diversity for …
A core problem that has been addressed in the scientific reform movement so far is the low rates of reproducibility of research results. Mainstream reform literature has aimed at increasing reproducibility rates by implementing procedural changes in …
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 …
Effect sizes are the currency of psychological research. They quantify the results of a study to answer the research question and are used to calculate statistical power. The interpretation of effect sizes—when is an effect small, medium, or …
Survey researchers take great care to measure respondents’ answers in an unbiased way; but, how successful are we as a field at remedying unintended and intended biases in our research? The validity of inferences drawn from studies has been found to …
The analysis of longitudinal observational data can take many forms and requires many decisions, with research findings and conclusions often found to differ across independent longitudinal studies addressing the same question. Differences in …
