Our newest pre-print: how does predictive processing account for higher level cognition?
What can grounded cognition help?
And how does this fit into life mind continuity?

I successfully defended my PhD yesterday!
Big thank you to a great commission and especially my supervisors 🤝🏻👨‍🎓
Unbelievably happy I get to do this job

Only 2.5% of animal biomass is human.

Still, that fraction is reshaping the fate of the whole 🌍.

My latest post - A tale of a thousand models

It implies that robust intelligence does not require more accurate representations, but more diverse ways of being coupled to the world.

A Tale of a Thousand Models:

In today’s post, I am further exploring the notion of models and mental models. We often speak of mental models as though they are neat packages of knowledge stored somewhere in the mind. These mod…

Thinking about writing a pop science book about the brain (“Your Brain on Everything”) where the big reveal is that all the brain names were randomized and I was actually talking about psychology the whole time.

The "reproducibility crisis" in science constantly makes headlines. Repro efforts are often limited. What if you could assess reproducibility of an entire field?

That's what @brunolemaitre.bsky.social et al. have done. Fly immunity is highly replicable & offers lessons for #metascience

Archerfish make lightning-fast decisions to catch prey, but their aim isn’t hardwired. They can adapt to new physics and generalise rules across contexts, all in under 100 ms.

I've been building a model of how intrusive thoughts can warp cognitive maps (world model) in PTSD & derail goal-directed behavior. It combines successor representation & prioritized replay. I started off with a grid world, then embeddings. Today in a story recall task, reading the text was moving:

At the market I bought bread and carried it home.
I am back at the crash.
I am back at the crash.
I am back at the tail-lights.
I am back at the crash.
I am back at the tail-lights.
I am back at the crash.
I am back at the crash.

New paper: "Large Language Models and Emergence: A Complex Systems Perspective" (D. Krakauer, J. Krakauer, M. Mitchell).

We look at claims of "emergent capabilities" & "emergent intelligence" in LLMs from the perspective of what emergence means in complexity science.

If you haven't been looking recently at the Open Encyclopedia of Cognitive Science (oecs.mit.edu), here's your reminder that we are a free, open access resource for learning about the science of mind.

Today we are launching our new Thematic Collections to organize our growing set of articles!

The biggest reason we don't actually have a "replication crisis" is that science is a process of advancing what's working, and not fixing what hasn't. Sometimes it's slow, and we backtrack a bit. But it's never stalled.

That said, the strain on scientific publishing is generating a lot of crap.

From Trump's new Gold Standard Science executive order, an error on the scale of the day 1 EO definition of sex.

Popper is rolling over in his grave.

“falsification” is manipulating research materials, equipment, or processes, or changing or omitting data or results such that the research is not accurately represented in the research record;

Reflecting on temperatures averaged over the last 3 months - what's it like in your area?

🟥 warmer than average
🟦 colder than average

Dataset (NOAAGlobalTempv6) described in doi.org/10.1175/BAMS...

Global map showing surface air temperature anomalies for the February 2025 to April 2025 period across the entire planet. Most all areas were warmer than average, especially in the Arctic. This data set is from NOAA's NOAAGlobalTempv6.0.0 using anomalies with a 1971-2000 climate baseline. Red is shown for warmer than average temperatures, and blue is shown for colder than average temperatures.

Huh. Looks like Plato was right.

A new paper shows all language models converge on the same "universal geometry" of meaning. Researchers can translate between ANY model's embeddings without seeing the original text.

Implications for philosophy and vector databases alike. arxiv.org/pdf/2505.12540

Just to double check: you asked experts to agree with quadruple barreled items incl. numerous elements as well as “may be” constructions?
