Better late than never: I graduated last month and started my PhD last week! 🥳
I’ll spend the next four years exploring how to make theory-based predictions of plausible effect sizes! 📚📈
Goodbye, Bochum – I will miss you! And hello, Eindhoven! 🚀

"The rewards to 'discovering' a spectacular scientific finding [in psychology] are large; the rewards to debunking frauds or deflating exaggerated claims are small if not non-existent. If these are the rules of the game, we should not be surprised at the way the game is played."
When psychologists mislead us
From Piltdown Man to the Stanford prison experiment, many famous scientific discoveries have been exposed as hoaxes or distortions

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.

Now this is a new one: My university's license of SAGE journals allows me to view but not to download the research articles. According to ChatGPT read-access costs 100K€ p.a. If you want to make 100% sure that interested readers can access your article, publish it in a #diamondopenaccess journal.

It's time to decide on a forever name for papercheck (scienceverse.github.io/papercheck/). We don't want it to be confused with papercheck.ai, and we plan to check other research artifacts like repo contents, data, code, and prereg. Any suggestions?
