This recent blog post provides a very accurate and useful summary of Bertram and I's recent Nature Reviews Psychology article on the value of self-reports relative to "implicit measures" (as we defined them in the original article):

www.psypost.org/self-report-...

Self-report measures outperform implicit tools in assessing thoughts and feelings, new psychology paper argues

Self-reports outperform implicit measures, according to a new review, offering greater reliability, predictive validity, and flexibility. The paper challenges beliefs about implicit tools’ robustness,...

New research shows that simply changing how a reaction vessel is positioned on a magnetic stirrer can significantly change a reaction's speed and product quality, influencing the reproducibility of results. #ChemSky #ScienceSky #EduSky

Position of flask on magnetic stirrers can drastically affect reproducibility of experiments

Comprehensive examination reveals improper siting of reaction vessels can affect catalyst formation, alter nanoparticle formation and change yields

“52% of all autocratization episodes become U-Turns, which increases to 73% when focusing on the last 30 years. The vast majority of U-Turns (90%) lead to restored or even improved levels of democracy”

Major new paper by finds implicit measures like the IAT are no better than asking people directly about their biases. After decades of avoiding self-reports, turns out our sophisticated replacement tools work no better than what we abandoned. New post!

Are interoception and mental health linked? Many assume so, with interoception even described as a psychiatric “p-factor.” But in our latest preprint, we were surprised to find little evidence for such a connection. www.medrxiv.org/content/10.1... 🧵 Thread with our reflections on the matter 👇

Interoceptive Ability is Unrelated to Mental Health Symptoms: Evidence From a Large Scale Multi-Domain Psychophysical Investigation

Interoception-the sensing and perception of the internal viscera-is widely cast as a transdiagnostic mechanism linking brain-body interaction to mental illness. Prevailing models propose that altered ...

It is amazing that most organizations (businesses, media, NGOs, political parties) that worried about the threat of the far right for decades have spent no time or energy to thinking how to operate in a far right world. They just continue to do the same and are surprised by a different outcome.

74% of Europeans say their country benefits from EU membership—the highest support recorded in 42 years.

With peace and security top of mind.

66% want a greater role for Europe in protecting them against global crisis & security risks.

We hear you. And we’re ready to deliver.

I find it amusing that ChatGPT can write predictive processing theories that are about as plausible as many published versions. I guess they really are that predictable…

We also recruited “observers” who were matched with the original “actor” participants, shown their choices, and asked to predict the actors’ choice process. Actors were more accurate than observers, suggesting that their accuracy came from some kind of first-person introspection.

Honest people don’t lie. Or do they? Liars aren’t honest. Or are they?
One puzzling conundrum in contemporary politics is that politicians who seem to be estranged from facts and evidence are nonetheless considered honest by their followers.
