Our field has witnessed a rapid increase in the appeal and prevalence of the short report format over the last two decades. In this article, we discuss both the benefits and drawbacks of the trend toward shorter and faster publications. Although the …
The hypothesis of a Hierarchy of the Sciences with physical sciences at the top, social sciences at the bottom, and biological sciences in-between is nearly 200 years old. This order is intuitive and reflected in many features of academic life, but …
Background: We explore whether the number of null results in large National Heart Lung, and Blood Institute (NHLBI) funded trials has increased over time. Methods: We identified all large NHLBI supported RCTs between 1970 and 2012 evaluating drugs or …
Many published research results are false (Ioannidis, 2005), and controversy continues over the roles of replication and publication policy in improving the reliability of research. Addressing these problems is frustrated by the lack of a formal …
Although replications are vital to scientific progress, psychologists rarely engage in systematic replication efforts. In this article, we consider psychologists’ narrative approach to scientific publications as an underlying reason for this neglect …
Newly discovered true (non-null) associations often have inflated effects compared with the true effect sizes. I discuss here the main reasons for this inflation. First, theoretical considerations prove that when true discovery is claimed based on …
Here I outline some of what science can tell us about the problems in psychological publishing and how to best address those problems. First, the motivation behind questionable research practices is examined (the desire to get ahead or, at least, not …
Publication selection bias is a serious challenge to the integrity of all empirical sciences. We derive meta-regression approximations to reduce this bias. Our approach employs Taylor polynomial approximations tothe conditional mean of a truncated …
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 …
