Absolutely none of which matters when motorists speed, play on their phones, drive drunk/drugged/tired, or simply believe they own the road.

My first email this morning is from a resident about motorists speeding through pedestrian lights near homes, schools, a church and a library.

It's constant.
👀 Can you see me now?

The importance of visibility on our roads cannot be understated, particularly for vulnerable road users including pedestrians, cyclists, e-scooter drivers and motorcyclists.

New paper in @jclinepi.bsky.social led by my super cool PhD student @kahin-tai.bsky.social with the SHARE-CTD (@sharectd.bsky.social) crew. It is the 2nd paper in a “JCE trilogy” on data sharing by SHARE-CTD: the 1st one addressed the topic in broad terms, and the third will focus on data reuse.

When the World Bank publishes new poverty estimates, it makes headlines. But making sense of these numbers is harder than it looks! Inflation, PPPs, national poverty lines, real incomes…There’s a lot going on.

In this article my colleagues explain where the new numbers come from and what changed

In June 2025, the World Bank increased its extreme poverty estimates by 125 million people. This doesn’t mean the world has gotten poorer: it reflects a new, higher International Poverty Line of $3 a ...

Want to get deeper intuition for a mathematical or statistical concept?

I find that one of the best ways is to dig into its history.

Now might be a good time to repost this story about what scientists actually know about the complex causes of autism, and what's behind the increasing prevalence.

Autism is on the rise: what’s really behind the increase?
RFK Jr has vowed to find out what’s responsible, but scientists say he is ignoring answers from decades of research.

New blog post from Data Colada, responding to the recent criticisms on p-curve analysis. It is a *very* good response. As in, it addresses exactly the points I would have expected in a reply, and it explains why I will still teach p-curve analysis. datacolada.org/129

"OpenAi déclare ne pas être responsable du suicide d'un utilisateur dont le chat a encouragé le suicide, parce que se suicider est interdit par les conditions d'utilisation"

...est une des phrases les plus dystopiques que vous lirez aujourd'hui

Mais bordel.
OpenAI says they aren't liable for the suicide of a user their chat bot urged to kill himself because suicide is a violation of the TOS
Additionally, OpenAI argues its not liable because Raine, by using ChatGPT for self-harm, broke its terms of service

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 🙂

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'?
