Justify your alpha

In response to recommendations to redefine statistical significance to P ≤ 0.005, we propose that researchers should transparently report and justify all choices they make when designing a study, including the alpha level.

Logical and methodological issues affecting genetic studies of humans reported in top neuroscience journals.

Genetics and neuroscience are two areas of science that pose particular methodological problems because they involve detecting weak signals (i.e., small effects) in noisy data. In recent years, increasing numbers of studies have attempted to bridge …

Longitudinal Structural Equation Modeling (Methodology in the Social Sciences)

Featuring actual datasets as illustrative examples, this book reveals numerous ways to apply structural equation modeling (SEM) to any repeated-measures study. Initial chapters lay the groundwork for modeling a longitudinal change process, from …

Measurement error and the replication crisis.

The assumption that measurement error always reduces effect sizes is false

Measurement Matters

This resource list contains reading material on the topic of measurement in psychological sciences. We hope the list will be a useful tool in helping researchers to improve measurement practices, and inspire debates about measurement in psychology. …

Meta-analyses are no substitute for registered replications: a skeptical perspective on religious priming

According to a recent meta-analysis, religious priming has a positive effect on prosocial behavior (Shariff et al., 2015). We first argue that this meta-analysis suffers from a number of methodological shortcomings that limit the conclusions that can …

Methodological Advances in Behavioral Research: Crowdsourcing Science

The results of many published studies across many scientific domains are not easily reproduced by independent laboratories. For example, an initiative by Bayer Healthcare to replicate 67 pre-clinical studies led to a reproducibility rate of 20-25% …
