Uncovering Illusions of Understanding: A Falsificationist Perspective - Computational Brain & Behavior
In a complex world, scientific explanations are always incomplete. Therefore, can we say that scientists generally suffer from “illusions of understanding?” I argue that embracing a falsificationist p...

Eine weitere Stellungnahme der @dgps.bsky.social zum drohenden Kahlschlag durch Union und SPD. www.dgps.de/aktuelles/de...
dgps.de
Weitere geplante Änderungen im GKV-Beitragssatz Stabilisierungsgesetz gefährden eine evidenzbasierte psychotherapeutische Versorgung, die Ausbildung zukünftiger Psychotherapeut:innen und damit eine zentrale Säule der wissenschaftlichen Psychologie. Angesichts zunehmender psychischer Belastungen in Zeiten multipler Krisen braucht es eine Stärkung psychischer Gesundheit – nicht den Abbau bewährter Versorgungsstrukturen. Die Deutsche Gesellschaft für Psychologie (DGPs) appelliert daher, wissenschaftlich fundierte Psychotherapie langfristig zu sichern und verlässliche Perspektiven für Patientinnen und Patienten, psychotherapeutische Versorgung und die nächste Generation von Psychotherapeutinnen und Psychotherapeuten zu schaffen.

"What follows are the five horsemen of the significance apocalypse [...] To the truly free-spirited researcher, they are a coordinated assault on productivity, publishability, and the ancient scholarly right to discover one’s hypotheses only after the data have had a proper chance to speak." 😅

Great quote by Cronbach, Gleser & Nanda (1972): "The tidy theory of error laid down for psychology at the start of the century by Spearman and Brown has always seemed just a little too tidy to describe the perverse behavior of real data." 😅

Maybe one's own discipline and background matter for the subjective impression. A lot of money seems to come from areas other than the social sciences, so there are likely many more published papers in those areas.

Daniel Heck @danielheck.bsky.social · 24/03/2026
Not sure how they counted the articles. I assumed that if the journal has a different name (i.e., subfield-specific outlet), there should be a separate count.

Conclusion of the paper: "Instead of making scholarly publishing sustainable and accessible for all, high APCs and transformative agreements aim to preserve the status quo, where academic publishing is a highly profitable business for a few corporations."

This is mainly due to the large number of published articles: "Scientific Reports published 73,206 articles and Nature Communications 16,122 articles between 2015 and 2018"

Does it make sense to preregister simulation studies? This question has sparked a lot of debate. ▶️We* work through the why, when, and how ▶️We discuss different phases of methodological research to clarify where preregistration might (or might not) add value 📝 Preprint: doi.org/10.31234/osf...

Yes, it's a classic paper experimental researchers should know about. I was surprised that ANOVA of proportions has still been used relatively often in the literature on the truth effect.

Great, thanks for the detailed and constructive feedback and suggestions! You are right that the current framing might not highlight the core issue of aggregation clearly enough. The paper is currently submitted, but we will consider PCI: Psych in the future, thanks for the hint.

Agreed!👍 However, it took me a while to understand that all main effects in the probit GLMM are simply effects on the response bias c, whereas all interactions with the factor indicating noise/signal of the stimuli can be interpreted as (main or interaction) effects on the discriminability d'.

The method worked better than simple aggregation for validation words such as "fifty-fifty chance", "never" or "always" (indicated in the plot by the black intervals compared to the gray interval areas).

New paper by @matzekloft.bsky.social in Psychometrika🎉 We developed a model for aggregating response intervals which are obtained if a participant judges that the word "most" covers the range [86% - 97%]. The model aggregates such intervals while considering people's proficiency & item difficulty.

There still seems to be a lot of confusion about significance testing in psych. No, p-values *don’t* become useless at large N. This flawed point also used to be framed as "too much power". But power isn't the problem – it's 1) unbalanced error rates and 2) the (lack of a) SESOI. 1/ >

Simulation studies have a conflict of interest problem. The same team: - develops a new method - designs a simulation study to evaluate it However, the new method has to show good performance to get published. We propose living synthetic benchmarks to address the issue (doi.org/10.48550/arX...).
