Prestige over merit: An adapted audit of LLM bias in peer review Large language models (LLMs) are playing an increasingly integral, though largely informal, role in scholarly peer review. Yet it remains unclear whether LLMs reproduce the biases observed in human de...

Yet again, machine learning — even gussied up via the transformer architecture — encodes and reinforces societal biases.

This study reveals that LLM-based peer review relies heavily on author institution in its decisions.

Stats Talk - The Characterization of a Quantitative Imaging Method
Stats Talk - The Characterization of a Quantitative Imaging Method YouTube video by BAMM

Can statistics be fun? You might find it hard to believe, but I had a blast giving this talk on #statistics of quantitative MR methods at the latest @ismrm.bsky.social conference. And judging from the reactions, people had fun too. Have a look: www.youtube.com/watch?v=2ZTT...

Guest Post: An Editor’s Perspective on “My Very Last Issue.” - The Scholarly Kitchen BMJ's Medical Humanities Editor-in-Chief Brandy Schillace reflects on changes in publishing that are making important work harder to do.

Perspective from 17 years as a scholarly editor -

“…things will get worse before they get better — as evidenced by the recent resignation of an entire board ... We must be very careful, for we are losing something precious.”

"AI" creative writing looks passable to people who don't look at writing all day long. To editors, it pops out like a sore thumb. LLMs are glorified predictive text machines and they predict, well, predictably. PS: if you submit an "AI" story, the editor WILL remember you, and not in a good way.

I do not want AI-generated media.

I want more human-created content.

I want to see and experience things that humans have created.

Which one are you?
Among scientists are collectors, classifiers, and compulsive tidiers-up; many are detectives by temperament and many are explorers; some are artists and others artisans. There are poet-scientists and philosopher-scientists and even a few mystics.

Some papers are very difficult to read but that doesn’t necessarily mean they're deeper than other papers. Authors must work very hard to make their story easy to read and understand by others. Or as Stephen King says: "the shorter the book, the less bullshit".
