A nice reminder that it's hard to know how often simultaneous discoveries happen in science. Any measures based on scholarly literature will be severe undercounts due to secrecy or simply unpublished work

New piece w/ James Evans in Science explores what we call 'science after science', an era where our ability to control nature may exceed our ability to understand it; a new struggle to sustain curiosity & understanding under AI's predictive dominance. #ai #science

Twenty-five years ago, Ted Chiang wrote a prescient science fiction short that began: “It has been 25 years since a report of original research was last submitted to our editors for publication, makin...

How does peer reviewer diversity affect fairness in peer review and the direction of published science? We find a "geographical representation bias" in 60 STEM journals published by @ioppublishing.bsky.social.

Bad news for economists...
In families with several children of the same sex, the odds of having another baby of that sex are higher than of having one of the opposite sex

Sex at birth is not always random — mum’s age and genetics can play a part
Families with three or more boys, for example, are more likely to have another boy than a girl as the next child.

Do you remember Francesca Gino's claim on her website that HBS analyzed the "wrong data file" in their investigation, and that a "real file" proved her innocence?
HBS is now claiming that the "real file" was fabricated by Gino... and thus that Gino's claim was defamatory.

Why do we peer review?
In a new paper, we establish a self-interested reason: learning.
With a quasi-experimental design applied to admin data from 55 journals, we show reviewing a paper doubles chances of citing it in future work!

ChatGPT is useful case. OpenAI *still* prohibits access in major countries. But do these prohibitions actually work?
