*Differences in potential ratings account for half of the gender promotion gap
*Women’s lower potential ratings do not reflect future performance: women subsequently outperform male colleagues

Good thread. And a great example of the NYT framing a progressive advocacy group going through a period of chaotic management and labor conflict as Wokeness Gone Too Far.
I was at the Sierra Club during the period described in this article and although I have my criticisms, it gets the issues in the Club fundamentally wrong. A 🧵

Yes, some people's legacies are complicated. For example, Watson. After all, though he was racist, don't forget his other traits. For example, he was also sexist. And also anti-semitic. And a data / idea thief. So let's not forget all the different facets.

A week after the arXiv was forced to tighten down on submissions because of overwhelming volumes of AI slop, bioRxiv is throwing the doors wide open.
disappointed that @biorxivpreprint.bsky.social is implicitly endorsing the use of LLMs to replace scientific thought
@richardsever.bsky.social this is a short-sighted move and a net negative for science

For the first time, scientists have documented a plant that mimics the smell of injured ants to attract pollinators.
The discovery reveals that floral deception is more diverse than previously thought and suggests many other hidden plant mimicry strategies may still be undiscovered.
