Following the controversy surrounding the p-curve technique, I wanted to better understand how the z-curve (a technique that solves several problems with the p-curve) works. I created a Bayesian version of the z-curve in Stan, and I'm quite pleased with the outcome 🙂

NEW PREPRINT

Explainable AI refers to an extremely popular group of approaches that aim to open "black box" AI models. But what can we see when we open the black AI box? We use Galit Shmueli's framework (to describe, predict or explain) to evaluate

Scientific error-checking, difficulty: easy

Find some issues in this table of results from an RCT of vitamin D for COVID-19. There's a couple of obvious issues, and some that are less easy to spot.

One of the giants of social psychology was a serial sexual harasser.

This new report reveals how Miles Hewstone touched, bullied, and sexual harassed numerous women during his 18 years at the University of Oxford. It's amazing how often bullying and sexual harassment go together in academia.

Yesterday we were delighted to welcome @adrienfillon.bsky.social for two sharp and thought-provoking talks on scientific publishing practices and the limits of meta-analyses.

Thank you for inspiring us to pursue science that is more open and built on integrity.

Interesting read, but worth considering (as the article does) the selection bias introduced by a) who is willing to initiate an adversarial collaboration and b) who manages to compete and publish it.

In our next episode of Nullius In Verba we will dive into the history of metascience. The first mention of 'metascience' in the literature we could find is Morris, 1938. Do you know of an earlier mention of the term 'metascience'?

Will this study about ketamine's effect on neuroplasticity ever see the light (publication)? It doesn't seem that ketamine changed synaptic plasticity after 2 weeks and 4 infusions.

Someone just sent me this study, and all I can say is that I don't understand why anyone would bother investigating this question. 1/n

Ketamine/esketamine have been claimed to work by enhancing neuroplasticity (quote from a KOL: "call them neuroplatogenes").
In this study synaptic plasticity was directly assessed but there seemed to be a near-zero effect.
Results only posted on NCT in 2023. No journal publication yet, AFAIK.

We built the simplest possible social media platform. No algorithms. No ads. Just LLM agents posting and following.

It still became a polarization machine.

Then we tried six interventions to fix social media.

The results were… not what we expected.

Can We Fix Social Media? Testing Prosocial Interventions using Generative Social Simulation
Social media platforms have been widely linked to societal harms, including rising polarization and the erosion of constructive debate. Can these problems be mitigated through prosocial interventions?...

Just finished listening to this great episode by @stuartjritchie.bsky.social and @tomchivers.bsky.social on whether early-onset cancer rates are really up.
Can highly recommend—it’s not only a relevant topic, but also a great exercise in the care that’s needed when somebody gives you a number.

New article by me!

Cardiovascular disease mortality rates have declined by around three-quarters since 1950, but we rarely hear about it.

I explore some of the reasons behind the decline.
