From the description this is the sort of data I would have loved to get my teeth into. Tempting even now I am retired.

A little football (soccer) thread. When I was a kid I was quite into football, not fanatical but I went to a few games, watched on TV, followed Football Focus, Final Score and so on.

I decided to combine my need to top the leader table with my daily step count – which is how I found myself walking 10 miles a day while reading out sentences in Japanese, German, Spanish and French

Now out in Nature Neuroscience: "Fixation duration on natural scenes is explained by memory encoding not processing demand". www.nature.com/articles/s41... Our eyes don't linger because recognition is hard; they linger to remember. Let me take you on a quick tour. 🧵

Fixation duration on natural scenes is explained by memory encoding not processing demand - Nature Neuroscience

By combining magnetoencephalography and eye tracking, this study sheds light on why people fixate on some parts of natural scenes longer than others. Rather than visual complexity, fixation durations ...

There are a few more metascientific implications I'd like to highlight. 1. When reporting replicability rates, there are multiple levels of uncertainty that needs to be modeled in a hierarchical way, and metascientific practice flattens all to the lowest level, masking much of it in the process.

📣 The difference between replicable and not replicable is not itself scientifically replicable. 📣 New work with Erkan Buzbas, showing that verdicts such as "X% of results replicated" are based on an inferential machinery that doesn't work. arxiv.org/abs/2604.26268

Screenshot of a paper's title page. Title: "The Difference Between 'Replicable' and 'Not replicable' is not Itself Scientifically Replicable". Authors: Berna Devezer and Erkan O. Buzbas, both at the University of Idaho — Devezer in the Department of Business and the Institute for Modeling Collaboration and Innovation, Buzbas in the Department of Mathematics and Statistical Science. Authors contributed equally. Corresponding author: bdevezer@uidaho.edu. Abstract: Replication studies estimate the replicability rate of scientific results by aggregating binary verdicts of experiments. Exact replications are rarely attainable, so most replication sequences are non-exact. Experiments differ in ways that matter and do not share a single common data-generating process. We formalize two statistical interpretations of this non-exactness. In a shared latent rate model (benchmark), experiments are exchangeable and depend on a common random replicability rate. In a conditionally independent rates model (operational), each experiment has its own replicability rate drawn independently from a population distribution. Under the shared latent rate model, even small variability among replicability rates induces an irreducible variance floor on the estimated mean replicability rate that cannot be eliminated by adding more replications. Under the conditionally independent rates model, the degree of non-exactness is not identifiable from standard replication data, because one binary verdict per experiment contains no information about between-experiment heterogeneity. Researchers therefore cannot tell which precision regime they are operating in or whether high- and low-replicability sequences can be distinguished in principle. As a result, the usual data structure of one binary verdict per experiment cannot support reliable demarcation between "replicable" and "not replicable" results and systematically understates uncertainty, making high- and low-replicability sequences appear discrim…

This is intriguing and it models (among other things) an experiment we carried out back in 2004. Uncertainty underlies geometric effects on navigation and grid-cell tuning, Kang et al., preprint. www.biorxiv.org/content/10.1...

Very much on board with this. Uncertainty also predicts grid expansion in novel environments — where uncertainty is transiently high — extending the framework beyond the geometric distortions they cover here. https://doi.org/10.1101/2023.01.30.526278

This looks like a significant discovery from Doris Tao's lab: Rapid concerted switching of the neural code in the inferotemporal cortex @nature.com "..our findings indicate that there is a previously unknown mechanism for neural representation:.." www.nature.com/articles/s41...

Face cells in the macaque inferotemporal cortex are initially able to detect faces and then rapidly switch to a face-specific neural code to discriminate between different face identities.

Trump does not think strategically, historically, geographically, or even rationally. He does not connect actions he takes on one day to events that occur weeks later. Allied leaders know that if they help him in the Gulf, he won't be grateful, or even remember www.theatlantic.com/ideas/2026/0...

Everyone but Trump Understands What He’s Done

Allied leaders know that any positive gesture they make will count for nothing.
