Inducing flexibllity mindsets are among the few treatments that influence, in particular, those with pronounced attitudes (not just the undecided fence sitters).

Flexibility mindsets: Reducing biases that result from spontaneous processing Spontaneous (i.e., heuristic, fast, effortless, and associative) processing has clear advantages for human cognition, but it can also elicit undesirable outcomes such as stereotyping and other bias...

Flexibility mindsets had similar effects on environmental intentions when induced within or outside the environmental domain. These results add to a line of research @kwinter.bsky.social and I and a number of other colleagues have conducted over the last > 10 years.

Flexibility mindsets enhance pro-environmental behavioral intentions among those with a low pro-environmental default tendency Environmental psychology provides several promising approaches to enhance pro-environmental behavior. However, these are usually only effective within…

New paper alert: @kwinter.bsky.social Laura Henn, and I show in 3 studies (N = 1005) that flexibility mindsets (induced by cognitive conflicts) enhance pro-environmental behavioral intentions among those initially low in pro-environmental attitudes.

Strong conspiracy beliefs about COVID = lower perceptions of procedural justice

Study: Conspiracy beliefs predict perceptions of procedural justice www.nature.com/articles/s41...

Delighted to see our new paper led by @svenjabfrenzel.bsky.social out. In a 5-wave longitudinal study (conducted in 2022/23), we tested whether the feeling of procedural justice returned for those high in conspiracy beliefs towards the end of the pandemic. Short answer: No! For more details👇

We explicitly focused on confirmatory research (sorry, I should have indicated that). And yes: at least one hypothesized pattern per prediction. If you a preregistration contains two hypotheses specifying two predicted patterns - even better. I guess we agree, but my post was not perfectly worded.

Do preregistrations in psychology live up to minimum standards? We argue in a new paper that they should at least contain the hypothesized pattern, the measures, the planned sample size and analyses, the exclusion criteria, and a time stamp. But do they? For more details read Lena Hahn's threat! 👇

Cover page for the manuscript: Morey, R. D., & Davis-Stober, C. P. (2025). On the poor statistical properties of the P-curve meta-analytic procedure. Journal of the American Statistical Association, 1–19. https://doi.org/10.1080/01621459.2025.2544397

Abstract for the paper: The P-curve (Simonsohn, Nelson, & Simmons, 2014; Simonsohn, Simmons, & Nelson, 2015) is a widely-used suite of meta-analytic tests advertised for detecting problems in sets of studies. They are based on nonparametric combinations of p values (e.g., Marden, 1985) across significant (p < .05) studies and are variously claimed to detect “evidential value”, “lack of evidential value”, and “left skew” in p values. We show that these tests do not have the properties ascribed to them. Moreover, they fail basic desiderata for tests, including admissibility and monotonicity. In light of these serious problems, we recommend against the use of the P-curve tests.

Paper drop, for anyone interested in #metascience, #statistics, or #metaanalysis! @clintin.bsky.social and I show in a new paper in JASA that the P-curve, a popular forensic meta-analysis method, has deeply undesirable statistical properties. www.tandfonline.com/doi/full/10.... 1/?

Elektromobilität: Warum es so viele Vorurteile gegenüber E-Autos gibt Fehlinformationen über Elektroautos sind in Deutschland besonders stark verbreitet – auch bei Gebildeten. Wie kommt das? Und was hilft dagegen?

Most people believe misinformation about electric vehicles, international survey finds More people believe misinformation about electric vehicles (EVs) than disagree with it, according to surveys of four countries, including Australia, Germany, Austria, and the US.

Surveys across four countries indicate that misinformation about electric vehicles is widespread and often linked to conspiracy mentality, but fact sheets and AI dialogues can help reduce these misconceptions. doi.org/g9psj2
