Positive Deviance Underlies Successful Science: Normative Methodologies Risk Throwing out the Baby With the Bathwater

Successful science needs deviant ideas that may challenge established norms. The last decade saw an unprecedented science-engineering project, with strict rules on preregistration, statistical testing, result-independent guaranteed publication, …

Positive Deviance Underlies Successful Science: Normative Methodologies Risk Throwing out the Baby With the Bathwater

Successful science needs deviant ideas that may challenge established norms. The last decade saw an unprecedented science-engineering project, with strict rules on preregistration, statistical testing, result-independent guaranteed publication, …

Power failure: why small sample size undermines the reliability of neuroscience

A study with low statistical power has a reduced chance of detecting a true effect, but it is less well appreciated that low power also reduces the likelihood that a statistically significant result reflects a true effect. Here, we show that the …

Power Posing: Reassessing The Evidence Behind The Most Popular TED Talk

A recent paper in Psych Science (.pdf) reports a failure to replicate the study that inspired a TED Talk that has been seen 25 million times. [1] The talk invited viewers to do better in life by assuming high-power poses, just like Wonder Woman's …

Pre-registration in social psychology—A discussion and suggested template

Pre-registration of studies before they are conducted has recently become more feasible for researchers, and is encouraged by an increasing number of journals. However, because the practice of pre-registration is relatively new to psychological …

Preregistering, transparency, and large samples boost psychology studies’ replication rate to nearly 90%

So-called “rigor-enhancing practices” suggest behavioral science can be reliable—but not everyone is convinced.

Preregistration Is Hard, And Worthwhile

Preregistration clarifies the distinction between planned and unplanned research by reducing unnoticed flexibility. This improves credibility of findings and calibration of uncertainty. However, making decisions before conducting analyses requires …

Preregistration Is Neither Sufficient nor Necessary for Good Science

To address widespread perceptions of a reproducibility crisis in the social sciences, a growing number of scholars recommend the systematic preregistration of empirical studies. The purpose of this article is to contribute to an epistemological …

Preregistration is not a panacea, but why? A rejoinder to Chen & Li's (2024) “infusing preregistration into tourism research”

A viewpoint published in Tourism Management articulates the potential benefits of preregistration and ‘debunking myths' surrounding this controversial open-science practice (Chen and Li, 2024). This rejoinder critically examines six key arguments …

Priming, Replication, and the Hardest Science

Concerns have been raised recently about the replicability of behavioral priming effects, and calls have been issued to identify priming methodologies with effects that can be obtained in any context and with any population. I argue that such …
