The Max Planck Society has begun an exploratory round table for open science. We are drafting some recommendations to leadership. Still a long way to go! But here are my notes on the most recent draft, just so you all know how I am trying to steer things.

I'm teaching Statistical Rethinking again starting Jan 2026. This time with live lectures, divided into Beginner and Experienced sections. Will be a lot more work for me, but I hope much better for students.

I will record lectures & all will be found at this link: github.com/rmcelreath/s...

If the field did an order of magnitude fewer studies total, and instead pooled resources to do more of these, knowledge production would dramatically accelerate.

We learn more from this one paper than from 50 one-offs examining the predictive validity of implicit measures.

“We are hungry for the curtain to be pulled back … we want all the gory details and imperfections of a study out on the table, open and transparent for deep consideration. It is with and through this transparency that we step from the world of less good practices to the world of better ones.”

ANSWER: 0 (yes, ZERO!)

This is a result of an analysis done by a student in my grad seminar, using a large dataset (N=307,313).

What this result might mean: Nobody's personality is truly "average," and people's personality profiles (at least Big 5) might be more "jagged" than we think.

(🧵 1/5)
Imagine you have Big 5 personality scores from over 300,000 people. You designate the scores in the "mean +/- 0.25 SDs" range for each trait (~20%) as the average range.

QUESTION: How many people in this >300K sample do you think fall in the average range for ALL 5 TRAITS?

What's your answer?

Experimentology is out today!!! A group of us wrote a free online textbook for experimental methods, available at experimentology.io - the idea was to integrate open science into all aspects of the experimental workflow from planning to design, analysis, and writing.

I'm working on PaperCheck today, and would love to take queries about whether it could do something you'd like to accomplish more easily in your metascience workflow. I'll try to show you how, and maybe even get you to collaborate on adding a module!

Many-analysts approaches can help uncover analytical insecurity. The Journal of Robustness Reports publishes short reports that check alternative analytical approaches for articles. Very cool! 💪 #SIPS2025 @improvingpsych.org #OpenScience

My editorial on how journals can earn trust.

We often use journal names as proxies for quality. This is bad bc it’s not valid. But it could be. Editors could make journal name a valid signal. And we could place value on journals that show us how they do that.
