A number of scholars recently have argued for fundamental changes in the way psychological scientists conduct and report research. The behavior of researchers is influenced partially by incentive structures built into the manuscript evaluation …
The past several years have been a time for soul searching in psychology, as we have gradually come to grips with the reality that some of our cherished findings are less robust than we had assumed. Nevertheless, the replication crisis highlights the …
Most discussions of rigor and replication focus on empirical practices (methods used to collect and analyze data). Typically overlooked is the role of conceptual practices: the methods scientists use to arrive at and articulate research hypotheses in …
Publication bias is the tendency on the parts of investigators, reviewers, and editors to submit or accept manuscripts for publication based on the direction or strength of the study findings. Much of what has been learned about publication bias …
Short and rapid publication of research findings has many advantages. However, there is another side of the coin that needs careful consideration. We argue that the most dangerous aspect of a shift toward “bite-size” publishing is the relationship …
Psychologists must change the way they conduct and report their research—this notion has been the topic of much debate in recent years. One article recently published in Psychological Science proposing six requirements for researchers concerning data …
Background: The p value obtained from a significance test provides no information about the magnitude or importance of the underlying phenomenon. Therefore, additional reporting of effect size is often recommended. Effect sizes are theoretically …
We studied publication bias in the social sciences by analyzing a known population of conducted studies—221 in total—in which there is a full accounting of what is published and unpublished. We leveraged Time-sharing Experiments in the Social …
There is some evidence that in fields where statistical tests of significance are commonly used, research which yields nonsignificant results is not published. Such research being unknown to other investigators may be repeated independently until …
