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 …

Meta‐regression approximations to reduce publication selection bias.

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 …

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% …

Methods and results of studies on reporting guideline adherence are poorly reported: a meta-research study

We investigated recent meta-research studies on adherence to four reporting guidelines to determine the proportion that provided (1) an explanation for how adherence to guideline items was rated and (2) results from all included individual studies. …

Minimizing Variability in Developmental Fear Studies in Mice: Toward Improved Replicability in the Field

In rodents, the first weeks of postnatal life feature remarkable changes in fear memory acquisition, retention, extinction, and discrimination. Early development is also marked by profound changes in brain circuits underlying fear memory processing, …

Mitigating Illusory Results through Preregistration in Education

Like performance-enhancing drugs inflating apparent athletic achievements, several common social science practices contribute to the production of illusory results. In this article, we examine the processes that lead to illusory findings and describe …

Moving Toward Transparent, Open, and Reproducible Prevention Science: Introduction to the Special Issue

This editorial serves as a brief introduction to this special issue of Prevention Science, entitled “Transparency, Openness, and Reproducibility: Implications for the Field of Prevention Science.” The overall goal of this special issue is to …

Negative results are disappearing from most disciplines and countries

Concerns that the growing competition for funding and citations might distort science are frequently discussed, but have not been verified directly. Of the hypothesized problems, perhaps the most worrying is a worsening of positive-outcome bias. A …

Negativity towards negative results: a discussion of the disconnect between scientific worth and scientific culture.

Science is often romanticised as a flawless system of knowledge building, where scientists work together to systematically find answers. In reality, this is not always the case. Dissemination of results are straightforward when the findings are …
