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 Any measures based on scholarly literature will be severe undercounts due to secrecy or simply unpublished work

After 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...

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

Bad news for economists...

Fewer women amplify their scientific voices online A new University of Michigan study finds that women are about 28% less likely than men to promote their scientific papers on X (formerly Twitter)—a seemingly minor digital decision that could have big...

Wow - an important read for #academicsky #scisky #medsky, about a study on professional social media activity by female scientists vs male, performed using @altmetric.com data from 2013-2018 (so, pre-Bluesky)

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.

In 1981 NYT published a piece on the then-new citation index, and how it was being used "unintentionally" for performance evaluations

Probability of citing manuscript within 3 years, by review status. Reviewers are more than twice as likely to cite reviewed paper in future work compared to invited reviewers who declined due to unavailability.

🏮NEW WORKING PAPER ALERT🏮

Scientists collectively spend tens of millions of hours peer reviewing each year, mostly for no $$. Why??

In new work w/ Charles Ayoubi and @innovation.bsky.social, we observe a private benefit for participating in evaluation: 💡💡Learning💡💡

Interesting take. Thanks for linking

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!

The gender gap in scholarly self-promotion on social media - Nature Communications The study shows a significant gender gap in scholarly self-promotion on Twitter, finding that women are about 28% less likely to promote their own academic papers compared to men, a disparity which is...

Men are much more likely to self-promote their papers on Twitter/X than women

No Kin in the Game: Moral Hazard and War in the US Congress | Journal of Political Economy: Vol 131, No 9 We study agency frictions in the US Congress. We examine the long-standing hypothesis that political elites engage in conflict because they fail to internalize the associated costs. We compare the vot...

Seems relevant: politicians are more likely to vote for war when they don't have sons who would do the fighting

I got fooled by AI-for-science hype—here's what it taught me I used AI in my plasma physics research and it didn’t go the way I expected.

No, I'd say conventional wisdom doesn't even conceptualize interdisc. as topic vs knowledgebase, it's usually just 1 dimensional. We see that conceptualization as one of our contributions.

Feels reasonable to me too. But that's not quite the conventional wisdom 🤷

Interdisciplinary research has consistently lower funding success - Nature The degree of interdisciplinarity in research proposals negatively correlates with funding success across a wide range of research fields.

Yup, you're right.

Here's one study of grants:

Tldr: conventional wisdom only partially true, depends on
- which interdis. type we're talking about
- how types align with each other and audience

www.pnas.org/doi/10.1073/...

Conventional wisdom says interdisciplinary research is valuable but harder to get through peer review (need to please diverse reviewers, etc).

@sdxiang.bsky.social Daniel and I partnered with @ioppublishing.bsky.social to test this wisdom and add nuance
