A Sunday morning Data Wrangling Exercise...

Gaurav Sharma and I discussed what this new Sh-Index means. Post-preprint and now featured in Nature Index, there has been vocal criticism and rightly so. We discussed again and I have been using it not actually intended. Also.. 🧵 1/8
I know the modified H index (or the Sh index) is getting a lot of grief in social media discussions but it allows a simple calculation: what’s the difference between your h index and your Sh index? If that difference is small or zero, what does that tell us about what kind of collaborator you are?

Seeing some meltdowns over this this morning. To be clear, this is an optional browser extension by creators unaffiliated with Google. GS itself still just reports the vanilla h-index.

Goodhart's Law is among my favorite adages ("when a measure becomes a target, it ceases to be a good measure").

Researchers welcome the initiative, but say it doesn’t go far enough to capture the nuance of researcher productivity and impact.

Despite the negative feelings about this, I sense some complementary metric like this that measures leadership vs collaboration would be very informative

This sh index will give something for researchers to argue about for the next few months.

Like h index, but extra points for the first & last authors.

𝘩-index, a popular measure of impact based on publications and citations over time, treats all of an author’s papers equally, regardless of their position on the paper. GScholarLens, a browser extension, aims to change this for Google Scholar users. #AcademicChatter www.nature.com/articles/d41...

Thank you for writing about this. The Sh-index is normalised & more informative than h-index. A small difference between Sh- & h-index suggests active involvement in lead projects, while a large drop indicates citations mainly from coauthored rather than lead contributions.

this is cool: Google Scholar extension that automates what many people already do when viewing a profile: adjusting the metrics

eg if a person is 27th author on a paper w/ 10K cites....probably that should be downweighted

metrics suck but they aren't going anywhere, so may as well use better ones

Our lab’s open-science tool, GScholarLens, has been featured by @nature.com, beautifully written by Dalmeet Chawla @dalmeet.bsky.social.
The article highlights how it brings transparency to scientific metrics using authorship weightage.

Visited the iconic @institutpasteur.bsky.social in Paris, a cradle of microbiological discoveries for over a century. Huge thanks to @sgribaldo.bsky.social for a wonderful discussion on phylogenomics & microbial evolution happening in our labs.
