Reviewers 5 months after the deadline when the editor sends urgent reminders to submit their reports

I think refereeing papers is increasingly going to require enough knowledge and judgment to tell when an author has actually read the literature they are citing. I’d say half of my reject recommendations lately have come from the fact that the authors evidently don’t understand the context.

I currently have three papers in review at "high impact" journals. One of them has been sitting there for two years. In that time my daughter was born and learned how to walk, but apparently publishing a PDF was still not possible for me. For another one, after four months in review the editor told me they cannot find a second reviewer and asked me to suggest more reviewers. A third one sent me a message in 2026 saying the PDF I uploaded was larger than 10 MB and that I should please reupload everything to make the file smaller. All of this just to eventually pay between 7,000 and 12,000 USD per paper so someone can officially approve that the science we do is "legitimate". Reminder: not a single reviewer will be compensated here. I still don't understand how we as scientists can collectively be so smart when doing science and still tolerate a system like this when it comes to sharing our findings. We should move to preprints plus open review, whether human or AI, asap. So frustrated about it. I'd suggest sharing your work on bioRxiv or medRxiv, reading and reviewing preprints when you can, and highlighting good research, especially if it is still a preprint. Try platforms like ResearchHub (that pay for peer review) and experiment with AI based reviewers for faster feedback. Instead I read this as a proposed "revolutionary" measure:

omg this title, this paper

I didn’t realize there were so many people getting destroyed by mattresses 😂

@jerryjliu0 The difference is the ML researcher had pattern recognition built up over years of reading papers. They knew which random shit was worth trying. That's the missing piece with vibe coding too. The instinct layer doesn't come free.

"We used to debate using tabs vs spaces in code we'd type out"

I tell my students that one of the main reasons not to over-rely on AI for research/writing is b/c--at some point--you're going to have a face-to-face conversation with someone who matters, and if you don't actually know some things, that interaction will not go well for you.

Today @kayhanlatifzade has defended his PhD thesis "Decoding Cognitive States from Neurophysiological and Behavioral Signals". Congratulations 🎉

I completely agree with this assessment. The tools we use shape our outlook on what’s possible. Current AI is trained to be exceptional at the average, but terrible at the rare. And losing the rare makes us kind of basic.
