This is an *excellent* post on cluster analysis. If you ever thought about applying cluster, latent class or latent profile analysis to psychological scales, you absolutely should read this!>

New blog post: "Cluster analysis: A skeptic’s guide". In which I ask a few questions that social scientists wishing to identify hidden classes in their data ought to address. janhove.github.io/posts/2026-0...
A two-dimensional scatterplot showing a three-cluster solution.

Caption: "Figure 2: A visualisation of a Latent Profile Analysis fit. Such visualisations may help readers appreciate that the clusters aren’t nicely separated and that the researchers’ notion of clusters may not correspond to their own."Table of contents:

Refresher: What is cluster analysis?
What are the clusters for?
What clusters, exactly?
Does the pipeline work?
What does the solution look like?
When running follow-up analyses, how is the uncertainty in the cluster assignments taken into account?
Was it worth it?
Conclusion

"The act of prediction is more than just an objective, educated guess about the future: it’s often an exercise of power that can help bend the future toward a desired outcome." New from me, on the book "Prophecy" by @carissaveliz.bsky.social - buttondown.com/creativegood...

Grateful and honoured to have joined the Cam-CAN team later in the study and to have helped write this up. Real shout-out and credit to the many people who have designed, run, and cared for the Cam-CAN study over the past 15 years!

Does signed prediction error influence declarative memory? This recent study takes a closer look - replicating prior findings, but uncovering an alternative explanation along the way! Doi.org/10.3758/s13421-026-01864-8

APA no longer shows me the actual paper, authors, abstract etc when I click on a paper in a search engine. Everything gated now, including basic paper info. Screenshots: (1) search hit (2) resulting APA site. Tried for a few papers now. What on Earth.

Given ChatGPT recommended this person should walk to the car wash to get his car washed it is hardly surprising to hear that it isn’t great at recommending when people should go to the hospital

David Lammy: "... because Cyprus is part of NATO" erm, Cyprus is not a member of NATO. Maybe its just a slip of the tongue? Except he repeats the claim just a minute later "... Cyprus is a NATO country" Does the deputy PM not know that Cyprus isn't a member of a NATO?

“Thousands of Cypriots are living there. British personnel are coming and going according to the duration of their terms but Cypriots are there. And if you want to safeguard British interest, 5% of the population are British. So how could you differentiate whom you protect and where in the island?”

Cyprus: 'We don't want to be dragged into this conflict'
Cyprus' High Commissioner to the UK, Kyriakos Kouros, has told Sky News that Cyprus wants "coordination" with the British government so that they do not "take decisions that affect our lives".

Do novel experiences shortly before or after learning improve memory for what was learned? They don’t according to Raza et al., but simply resting might. Read about novel VR experiences versus wakeful rest as ways to improve memory: doi.org/10.1177/17470218251346156

Over the years, I have written a few Jupyter/Rmd/Matlab notebooks that attempt to teach some statistical concepts, particularly in neuroimaging. You can find them here: www.mrc-cbu.cam.ac.uk/people/rik.h..., though I will say a bit more about each one in a number of posts over next few days.

Why do some people lose memory faster with age? A mega-analysis of 13 longitudinal datasets (3,700+ adults, 10,000+ MRIs) shows that memory decline tracks brain atrophy, especially in the hippocampus, and that these links strengthen with age, but not APOE status: www.nature.com/articles/s41...

Ask anyone who moved to the UK (EU or non-EU) how many documents, pieces of evidence of “legal right” to reside in the UK, and (unnecessary) personal and biometric information they had to continuously provide to the UK government over the years. Proving identity clearly isn’t the goal here.
