Good self-control has been linked to adaptive outcomes such as better health, cohesive personal relationships, success in the workplace and at school, and less susceptibility to crime and addictions. In contrast, self-control failure is linked to …
If psychologists have recognized the pitfalls of underpowered research for decades, why does it persist? Incentives, perhaps: underpowered research benefits researchers individually (increased productivity), but harms science collectively (inflated …
Background: This paper presents the first meta-analysis for the inter-rater reliability (IRR) of journal peer reviews. IRR is defined as the extent to which two or more independent reviews of the same scientific document agree. Methodology/Principal …
Crisis of replicability is one term that psychological scientists use for the current introspective phase we are in—I argue instead that we are going through a revolution analogous to a political revolution. Revolution 2.0 is an uprising focused on …
A recent paper by Chatterjee, Rose, and Sinha (2013) reported impressively large “money priming” effects: incidental exposure to concepts relating to cash or credit cards made participants much less generous with their time and money (after cash …
The preregistration of research protocols and analysis plans is a main reform innovation to counteract confirmation bias in the social and behavioural sciences. While theoretical reasons to preregister are frequently discussed in the literature, the …
Societies invest in scientific studies to better understand the world and attempt to harness such improved understanding to address pressing societal problems. Published research, however, can be useful for theory or application only if it is …
Publication bias remains a controversial issue in psychological science. The tendency of psychological science to avoid publishing null results produces a situation that limits the replicability assumption of science, as replication cannot be …
Over the last 50 years, we argue that incentives for academic scientists have become increasingly perverse in terms of competition for research funding, development of quantitative metrics to measure performance, and a changing business model for …
Open science practices, such as pre-registration and data sharing, increase transparency and may improve the replicability of developmental science. However, developmental science has lagged behind other fields in implementing open science practices. …
