In a preregistered research, we examined the relationships between conspiracy mentality (i.e., the individual susceptibility to endorse conspiracy theories, Bruder et al., 2013) and trust in three actors of the COVID-19 crisis: 1) Political institutions, 2) scientific and medical institutions, and 3) the medical personnel. While the two former grou...
We agree that external validity of social psychological experiments is a concern, we disagree these models are useless. Experiments, reconsidered from a situated cognition perspective and non-linearly combined with other methods (qualitative and simulations) allow grasping decision dynamics beyond bias outcomes. Dynamic (vs. discrete) insights rega...

The COVID-19 pandemic is a crisis which called for two crucial modes of social regulation: social control and social solidarity. In the present pre-registered study, we examine how the perceived non-compliance with health measures relates to attitudes towards these modes of social regulation, as well as to the role played by the perception of disin...
As researchers, we are advised to share our data to improve transparency and increase the reproducibility of experiments. Simultaneously, making data freely accessible can raise ethical questions regarding the participants' privacy. We first outline the challenges regarding "open data" for researchers in light of the GDPR. Then, we turn to the impa...
Student’s 't'-test and classical 'F'-test ANOVA rely on the assumptions that two or more samples are independent, and that independent and identically distributed residuals are normal and have equal variances between groups. We focus on the assumptions of normality and equality of variances, and argue that these assumptions are often unrealistic in...
Researchers often lack knowledge about how to deal with outliers when analyzing their data. Even more frequently, researchers do not pre-specify how they plan to manage outliers. In this paper we aim to improve research practices by outlining what you need to know about outliers. We start by providing a functional definition of outliers. We then la...
When comparing independent groups, researchers in psychology commonly use Analysis of Variance (ANOVA), which assumes data is normally distributed, and variances are equal across conditions. When these assumptions are not met, the classical ANOVA (F-test) can be severely biased, which leads to invalid statistical inferences. However, despite their...
