🚀Very excited to finally see our paper on nonsignificance misinterpretations published! 📈
Together, @ste_lee_murphy, @aurelio_fdez, Linda Reimann and I investigated the prevalence of "p > .05 = absence of an effect" interpretations. (1/4)

I am hiring a PhD student on the meaningful interpretation of effect sizes as part of my VICI funded project. This is a 4 year paid position in a welcoming and collaborative environment. Find out more or apply at tue.nl/werken-bij-tue/vacatu…

I think at some point we need to move from taking this as a serious ‘reason’ to be against preregistration, and call these people out for being too incompetent on research methods to take their opinion seriously. As we wrote doi.org/10.1080/2833373X.202…

The new workshop of Paul Meehl Graduate School, Causal Inference and Variable Control by Peder Isager, is open for registration. Check out the announcement below:
paulmeehlschool.github.io/20…
👫Of these, 23% suggested the absence of an effect at the sample level (e.g., 'groups were the same') and 58% at the population level (e.g., 'men and women are the same').

Very excited to share our new preprint! 📢
We investigated how often researchers misinterpret statistically nonsignificant results as the absence of an effect. Spoiler: it’s a lot (~81% of 599 articles)! Dive into our findings and their implications here: osf.io/preprints/psyarxiv/hm…

SAVE THE DATE! Excited to announce the upcoming NLRN Symposium, taking place on December 6th at the UMCG, Groningen. Mark your calendars and stay tuned for more details! #NLRNSymposium #SaveTheDate #DutchReproducibilityNetwork #TransparentResearch #Reproducibility
Exciting couple of days! Last week I received a teaching award for my statistics classes and yesterday one (of three) for the best talk at the German Conference for Student Research (#StuFo2024). Life‘s good lately! :)

Group sequential analysis is a technique to collect data in batches, analyze the data after each batch, and decide to continue or not – all while controlling your Type 1 error rate. It provides a lot of flexibility, while maintaining rigour. >

Super excited about this Winter School - some of the best meta-scientists, methodologists, and generally some of my favorite people together for a week. Sign up! It will be a blast!
We are thrilled to announce the International Winter School 2025:
“The 4Ms : Meta-research, Measurement, Multi-lab, and Multiverse data analysis in Behavioral Sciences"
📍February 17-21st, 2025, Padova, Italy.

Can you imagine if scientists or funders appreciated sleuths like this?
Or if we saw potential examples of misconduct as vulnerabilities in our processes that needed to be addressed?
I Hacked @NASA (again) and reported some vulnerabilities to them. Just today, I received this appreciation letter from them after they patched the loopholes!

Interesting presentations at the Paul Meehl graduate school day today. Spoiler: misinterpretations are very common 😬 @RaphaelMerz

Continuing after the coffee break with @RaphaelMerz about misinterpretation of non-significant results. It promises to be a talk full of memes!
Getting started with the Paul Meehl graduate school today! @FitzgeraldJack_ talking about the importance of economists embracing equivalence testing, and how they can move towards this.

Gino's case against us has been dismissed.
Scientists cannot effectively sue other scientists for exposing fraud/errors in their work.
Those who work to correct the scientific record can sleep better tonight. Those who don’t want it corrected, well, I don’t care how they sleep.
Sooo, I've been playing around with @SemanticScholar's API and, after a night of nearly wrecking my computer, I've managed to trim down the 200 GB original datasets to a much smaller ~4 GB psych-specific dataset. 1/2
