Thank you so much @nature.com Miryam Naddaf for featuring my research on #Attrition in #Science in October (and in January) in "Nature"!

Your coverage opened so many new opportunities, collaborations! Harvard, Stanford, Beijing, HKU.

The #Nature_Effect! It works...

Nearly 50% of researchers quit science within a decade, huge study reveals

Twenty years of publishing data across many countries and disciplines show women are more likely than men to leave research.

Good to remember! It is all about probabilities!

Katie Mack @astrokatie.com · Jun 19

Chatbots — LLMs — do not know facts and are not designed to be able to accurately answer factual questions. They are designed to find and mimic patterns of words, probabilistically. When they’re “right” it’s because correct things are often written down, so those patterns are frequent. That’s all.

⚖️ Yes—underperformance increases the risk of leaving academia.

But this applies to both men and women, challenging the idea that academic attrition is solely driven by performance-based self-selection.

Thank you #UNESCO for an invitation to act as one of 4 independent scientists in the Advisory Board!

It is an excellent opportunity to see how global organizations work in practice! My reading - they work very well, small teams, huge impact!

Extremely interesting work with and for a UN agency.

Let us not #underestimate (and #underfund) global organizations, they still have enough power to prepare solid - and consequential - global reports!
