What aspects of human knowledge do vision models like CLIP fail to capture, and how can we improve them? We suggest models miss key global organization; aligning them makes them more robust. Check out LukasMuttenthaler's work, finally out (in Nature!?) www.nature.com/articles/s41... + our blog! 1/3

In the end, even basic brain connectivity is different between rodents and primates, with primates having more specialized, sparsely connected brain regions.

unclear if Watson made a net positive or negative contribution to science.

Without him would the double helix have been figured out sooner or later?

Perhaps CSHL would not have grown to its eventual status

Perhaps a swathe of women and non-white researchers would not have been lost from science

Endorse, and I'd also add that it's nice to mention a few things you liked about the paper at the start of the review.
My reviewing style has changed over time. Rather than litigate every little thing, and pushing my own ideas, I focus only on 2 things:
(1) Are the claims interesting/important?
(2) Does the evidence support the claims?

Most of my reviews these days are short and focused.

Watson was a racist who, "near the end of his life, faced condemnation and professional censure for offensive remarks, including saying Black people are less intelligent than white people"

I saw Jim Watson speak in the flesh only once, in 2013. During the talk he mentioned the "historic curse of the Irish, which is not alcohol, it’s not stupidity. But it’s ignorance."

Personally I have never used an LLM to:
- review a paper
- review a grant
- mark student assessments

These are tasks I do not pass to LLMs because I am getting paid to do them and because I was asked to provide my individual professional judgement on their quality
November 7, 2025 at 9:31 AM
LLMs are already reviewing science... just often not declared
In the shorter term, we should resist the use of LLMs in reviewing science, and reform the system to avoid the problems we already have with human PR. A good start would be getting rid of journals and switching to post publication, open and ongoing review.

My prediction is that LLM peer review will slow down science. It will do this for precisely the same reasons that contemporary peer review does and some extra ones. Start by reading @hansonmark.bsky.social thread below, then read on. 🧵
Just tried q.e.d. by @odedrechavi.bsky.social et al. with a few papers including by myself & others where I knew a claim within was flawed based on a misunderstanding of the signal.

1) it was impressive. I see what the hype is about.
2) it hallucinated.

The advances we've made in statistics, experimental study design, and causal inference over the past century are remarkably useful for understanding our world. But there is never been a push to make people use them like we are seeing with generative AI. Perhaps take a moment to consider why.

We must change this mindset that the essential and most critical work in a field is always the first one. That distorted view has caused a lot of problems in psychological science already. The first work is just that—the start. Every field should be evaluated based on the complete body of evidence.
