A Tale of Two Science Reform Movements Reflections from meetings of Metascience 2025 and the Society for the Improvement of Psychological Science

New post! "A Tale of Two Science Reform Movements," in which I compare the recent #Metascience2025 and #SIPS2025 conferences, and find that I am much more at home at one than the other. getsyeducated.substack.com/p/a-tale-of-...

Super beginner friendly intro to how LLMs work! Even I understood it :)

Thanks to everybody who chimed in!

A cool discussion w/ some colleagues from the #NeuroSky community has triggered a new #ComplexityThoughts 👀

Regardless if you work w/ 🧠 or 🧬🧫, often we attack inverse problems in 🧪 w/ methods hiding tons of assumptions. I write about the case of #ComplexNetworks 👇

Writing about technical topics in an accessible manner A wise man – I’m quite sure it was Brian Wansink – once pointed out that it is impossible to both read and write a lot. So, maybe reading a post about how to write just steals time from the more urgen...

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...

The Fraudulent Science of Success Business schools are in the grips of a scandal that threatens to undermine their most influential research—and the credibility of an entire field.

In 2023, Harvard Business School suspended a star professor over charges of research misconduct.

As it happens, one of her papers also had funny data from a *different* B-school superstar -- a "mad, fraudulent unicorn,” per @jamesheathers.bsky.social... (1/3)

Thanks to the work of Ria Hoekstra and the gang, you can now formally compare n=1 idiographic network models with each other, using measurement invariance testing well understood from SEM.

The response time paradox in functional magnetic resonance imaging analyses - Nature Human Behaviour Mumford et al. examine how response time differences can lead to confounds in functional MRI analyses, and they propose a new time-series model to account for response time effects.
