Machiavellianism scales often miss key facets across affect, behavior, cognition, and desire. Our new paper in @collabrapsychology.bsky.social introduces the M4 scale, built with Ant Colony Optimization to capture Mach more comprehensively. It is freely available here: doi.org/10.1525/coll...

Assessing the ABCDs of Machiavellianism: Development and Validation of the M4 Scale Using Ant Colony Optimization, from @mp-grosz.bsky.social et al. doi.org/10.1525/coll...

New article by me! Cardiovascular disease mortality rates have declined by around three-quarters since 1950, but we rarely hear about it. I explore some of the reasons behind the decline. ourworldindata.org/cardiovascul...

This one is quite fascinating because it’s a very explicit attempt at methods harm reduction — people keep doing the shoddiest mediation analyses despite repeated criticism; let’s rebrand it as associational variable analysis to provide a more accurate label.

Our paper about the GIPO data has now been officially published at Personality Science. The paper is freely available at journals.sagepub.com/doi/10.1177/...

❕NEW PAPER❕ We developed the M4, a reliable & valid Machiavellianism scale capturing affective, behavioral, cognitive, and motivational aspects of Mach. Link: osf.io/preprints/ps...

Extremely excited to share the first effort of the Revived Genomics of Personality Consortium: A highly-powered, comprehensive GWAS of the Big Five personality traits in 1.14 million participants from 46 cohorts. www.biorxiv.org/content/10.1...

📊 NEW PAPER 📊 Our manuscript about the GIPO dataset (N = 1,460) is now accepted at Personality Science! 🎉 The freely available dataset includes measures of personality and prosocial & cheating behavior. 📄 You can find the accepted manuscript here: osf.io/preprints/ps... bsky.app/profile/mp-g...

🚨 New preprint! 🚨 Using nationally representative survey data from 142 countries (N = 128,093), I find that people who have experienced a climate-related hazard are more likely to consider climate change a 𝘷𝘦𝘳𝘺 𝘴𝘦𝘳𝘪𝘰𝘶𝘴 𝘵𝘩𝘳𝘦𝘢𝘵. 🧵 Link: osf.io/preprints/ps...

🚨 JOB! Full professorship (W3) in Personality Psychology / Interindividual Differences & Psychological Assessment at Uni Bremen.

This paper on tailored cutoffs for fit indices in SEM is great. Their simulation-cum-ROC approach is not only more informative but also more flexibly applicable (e.g., works also for second-order models and WLSMV) than other methods for finding tailored cutoffs. link.springer.com/article/10.3...

I’m excited to share my new preprint entitled “The Big Five Personality Traits are Composites Rather Than Common Causes”: osf.io/6ukqb_v1. 😀

if you're a PhD student or postdoc working at the interface of personality psychology and CS/ML (construed broadly on both sides), and are interested in doing a full-time, remote, 3 - 6 month internship/residency at MidJourney, please DM me some kind of resume or CV-like thing

This might be a serious problem for nonexperimental research on personality change because personality might influence whether someone participates in a (panel) study or not

Have you every found yourself wondering whether the most widely used measures of social cognitive ability measure what they are supposed to measure?

Want to make nice graphs with me, starting this summer? I am hiring for two PhD positions at the University of Witten/Herdecke.

7 years ago, I received funding for a project on personality, incentivized prosocial behavior & social status in groups. Today, we've made the anonymized data publicly available. Researchers can now use it by citing the preprint/paper (no need to add anyone as a coauthor): doi.org/10.31234/osf...

We have a freshly accepted manuscript about the influence of socially desireable responding on personality self-reports. Participants (N = 231) took the BFI-2 twice, first honestly and then with faking-good instructions in a job or dating context. Link to the preprint: osf.io/preprints/ps...

After a long wait, the working paper for the Many-Economists Project: The Sources of Researcher Variation in Economics. We had 146 teams perform the same research three times, each time with less freedom. What source of freedom leads to different choices and results? papers.ssrn.com/sol3/papers....

In case you need another reason to apply: There are eagle-owls nesting in the towers of Marburg's 13th-century Gothic church and you can observe (and hear) them almost every day at dawn 😱

We’re looking for a motivated researcher to apply for a Marie Skłodowska-Curie postdoc with our Econometrics & Data Science group at SDU! Focus: Causal Inference, Machine Learning, Big Data Full support for promising projects More info & apply: www.sdu.dk/en/om-sdu/in...

I talked to Özge Fischer-Baum from @psychscience.bsky.social about our recent paper on informal caregivers‘ wellbeing! Their podcast Under the Cortex is a really fun format 😊 www.psychologicalscience.org/news/utc-202...

People, just stop doing Frontiers special issues. Find a nice diamond open access journal, and self-publish and collaboratively peer review the set of papers you all want to write. Do not give Frontiers money. They add no value. If anything, they hurt your reputation. MDPI is of course even worse.

Emotions are reactions to situations we encounter in daily life. In our new paper in Psych Review (psycnet.apa.org/fulltext/202...; with @oisinryan.bsky.social and @fdabl.bsky.social), we take a first step towards building a generative model for emotion dynamics based on this simple principle 1/4

Special credit to Richard Rau for envisioning & spearheading this innovative project & app!

Interviewer: Can you explain this gap in your resume? Psychologist: causal inference is not possible without experiments, but I can describe the gap!

We are back with a new episode! @renemottus.bsky.social spoke with @ruben.the100.ci and Farid Anvari about the jingle jangle jungle of measurement and the unchecked proliferation of psychological tests. While there’s a lot of good in our field, there’s also room for improvement. Check it out!

Can people intentionally change their personality? Happy to share that our review on volitional personality change research has now been published at Nature Communications. Open-Access-Link: doi.org/10.1038/s442...

DAGs (causal graphs) can be used to understand the mechanics of linear interaction analysis. See more here: bpspsychub.onlinelibrary.wiley.com/doi/10.1111/...

Behind the first door of the 100% CI advent calendar is a new blog post! In which I hand out unsolicited writing advice -- with a focus on writing about technical topics in an accessible manner, but most of it is fairly general: www.the100.ci/2024/12/01/w...

Depression is preventable. Our individual participant data meta-analysis based on >7000 participants proved that psychological interventions reduce the incidence of depression within a year from 10% to 6%. authors.elsevier.com/sd/article/S...

Theorist bridge trolls barking at you to formally connect theory to data? Wondering how, without troll magic? We can help! "Bridging theory and data: A computational workflow for cultural evolution" With @dominikdeffner.bsky.social @natyfedorova.bsky.social Jeff Andrews. www.pnas.org/doi/10.1073/...

Excited to share our new paper in @EJP! 🎉 We found that how people think and feel about their goals varies most between different goals, then over time, and least between individuals...

My first postdoc @hkjach.bsky.social's main work has been finally published!! We assessed lots of curiosity personality traits and information-seeking task behaviors and examined the relationship. See what we found... www.pnas.org/doi/10.1073/...

NSF makes you say who you got conflicts (coauthored) with. We (really just Jordan Matelsky) just built you a tool for that. Literally one click: bib.experiments.kordinglab.com/nsf-coa

Currently working my way through @julianschuess.bsky.social and @pselb.bsky.social's "Graphical Causal Models for Survey Inference" for our journal club and so far it is a thing of beauty! Very clear language, clear arguments, meeting readers where they are etc journals.sagepub.com/doi/10.1177/...

I did the Many Minds podcast with Kensy Cooperrider, talking mostly about human intelligence. I can't bear to listen to myself, so give it a try and let me know what you think. @kensycoop.bsky.social @manymindspod.bsky.social disi.org/how-should-w...

Paper alert: across 10k participants & 36 versions of the emotional dot probe task, task *reliability* cannot be distinguished from 0 (!). Raises very serious questions about the literature (how did so many find positive relations between this task and other variables). #PsychSciSky

💡Glad to see this paper with Beyers Louw finally published: "On the Nuisance of Control Variables in Causal Regression Analysis" (preprint available on arXiv). doi.org/10.1177/1094...

Very excited to share psychometric analyses of our item bank for studying psychopathology multidimensionally and hierarchically in daily life. We hope these will bridge research on dimensions of psychopathology and dynamic processes in naturalistic settings (e.g., complex systems). 1/

🙌 Our paper on "Natural Experiments: Missed Opportunities for Causal Inference in Psychology" just got accepted in Advances in Methods and Practices in Psychological Science (AMPPS). Thanks to @mp-grosz.bsky.social, @dingdingpeng.the100.ci & a great coauthor team. Pre-print: osf.io/preprints/ps...

I will be in Toronto (UofT and York) this week, talking about "The Slow Progress towards Diversification in Psychological Research," or why despite 50+ years of awareness-raising, our samples are still quite limited. Working paper linked below if you are interested in such things. Comments welcome.

Loving this call for employing more natural experiments in psychology, so few studies (0.07% abstracts in a lit search they conducted) capitalize on natural experiments. There are so many random events and new policies launched all the time and all around us -let’s not miss these opportunities!

🎉 Thrilled to share that our manuscript on natural experiments has just been accepted at AMPPS! with @dingdingpeng.the100.ci Adam Ayaita @ruben.the100.ci @p-hunermund.com @azwpsy.bsky.social Susanne Bücker, Sven Rieger, Sandrine Müller, and Tobias Ebert! osf.io/preprints/ps...
