For the 4th time, @bramlancee.bsky.social & I, in collaboration with AMCIS, organise a workshop on survey experiments on 5 Oct. 2026. CfP below ⬇️. We particularly welcome papers/research designs from early career researchers. Deadline for submissions: 23 Aug. @aissr.bsky.social

As an adult, can I sign up voluntarily?

🧑🏻‍🏫 Do you teach statistics? 📊 Have you ever taught ANOVA? ⏰ Do you have 5 minutes to spare? Then participate in our survey and help us improve statistics education! run.pavlovia.org/pavlovia/sur... #stats #edusky #mathsky #scisky #academicsky

New working paper with @robertboehm.bsky.social: it is an early version likely needing significant revision, so feedback is very much appreciated. We review multi-level games: a family of economic games that capture tensions within and between groups simultaneously. (1/5) doi.org/10.31234/osf...

Today's Cooperation Colloquium!

A special Cooperation Colloquium this week: Shuxian Jin @shuxianjin.bsky.social The cultural logic of honor in cooperation and punishment across societies Date: Friday, May 22 Time: 15:00 UTC+2 (Vienna) / 9am ET (NYC) Sign up: list.ku.dk/postorius/li...

If you are an early-career researcher (PhD student, postdoc, or similar) in personality psychology, consider signing up for the EAPP Mentoring Programme: forms.gle/zH8DmY57eLQ6... Consider forwarding this call to early-career researcher who may be less likely to be aware of this programme.

I think a big problem has been a kind of confused circular logic where people (especially researchers, but not political scientists) go “Things seem bad and polarized. What is polarization? It’s a bimodal opinion distribution. Anything that produces a bimodal opinion distribution is bad!”

Just saw that Die Zeit did a big interview with Carlson as well. Maddening. Repeat after me: you. Don’t. Platform. Fascists.

This looks like a paper every personality psychologist should have an opinion on. I've often defended broad factor models to cognitive scientists and economists who look at them askance because they are genuinely useful, but it's hard to argue that personality traits are common causes as modelled.

Shape the future of social science as a PhD student of machine learning-informed theory construction, based on patterns in high-frequency longitudinal data! You will be part of vibrant communities like the INSIGHT Lab, Theory Methods Society, and Tilburg Experience Sampling Center tiu.nu/23721

This strikes me as a terrible idea. The US government is not trying to enhance scientific integrity, no matter how they are framing their attacks on science. Treating their concerns and efforts as legitimate undermines genuine reform efforts.

Today's Cooperation Colloquium with @saptarshi.bsky.social is coming up in a few hours

Any recommendations for a (recent-ish) workflow or tutorial for mixed-effects modelling of experience sampling data in R? Looking for something to hand to my master's student.

Hey all! Been away from BSky for a while but this Friday I am giving a talk on our latest PNAS Nexus paper on repeated games! We model situations where players, instead of acting simultaneously, act in order. We study the status of well-known equilibrium strategies when simultaneity is broken.

Do you want to do a PhD in Judgment and Decision Making in two beautiful European locations on human-AI interaction? Well have I got news for you. @bahniks.bsky.social and I are recruiting a candidate to start around September 2026. See here: decisionlab.vse.cz/english/we-a...

This is worth a read even if you're not into evolutionary theory. Trivers' work was as obviously brilliant as his reported behaviour was awful. It forces us to consider how much space academia should give to people whose behaviour towards others is frequently hurtful.

Today on the Cooperation Colloquia:

Scientific Reports is just Frontiers for people who think their work should've been published in Nature. In my experience, their editors frequently have no clue about the research they are handling and their communication is shoddy. I no longer review for them.

If you drew an arrow ... you have a causal model. If you are calling some variables IV and others DV ... you have a causal model.

When I read a paper, I skip right to the regression tables, so clearly it's LaTeX formatting where true creativity resides.

Perhaps you received a mysterious noreply email asking you to evaluate some publications 'for novelty'. Looked kinda dubious? Yup, that's the one. So what's up with this 'metascience novelty indicators challenge'? 🧵

New blog post, inspired by the excellent recent qualitative paper by Makel and colleagues: On the reliability and reproducibility of qualitative research. I reflect on how I will incorporate realist ontologies in my own qualitative research. daniellakens.blogspot.com/2026/02/on-r...

There is a strange tendency in psychology in the face of shortcomings to call not for stronger evidence, but for weaker claims. Humility is a virtue, but it shouldn't become an excuse for lack of ambition.

New work by my amazing St Andrews colleague Amalia Bastos

📢 Call for Hidden Papers & Data on Ingroup Favoritism in Dictator Games We look for unpublished and hard-to-access experimental studies for our meta-analysis! Inclusion criteria: no deception, adults, manipulation of group membership of dictator game recipients. All tips and data very welcome!

Useful thread, though I hope somebody will create a spreadsheet (or Wikipedia entry, perhaps). And then let's not forget the abusers and bullies who aren't famous enough to have received emails from Epstein.

Highly recommend Replication Games! Key takeaways: 1. Great way to learn about other psych methods 2. Improve on stats 3. More enjoyable with others 4. Realised my own code needs improving after being on the other side of a paper (replicating) Thanks @fialalenka.bsky.social @rujoanna.bsky.social
