Is anyone willing to share their slides on philosophy of science for undergraduate (statistics) students, especially as it pertains to the hypothetico-deductive framework? Here are my current notes on the topic: lnkd.in/eB-TZGDK

Any experiences with "Journal of Computational Social Science"? I reviewed a manuscript that should have been desk-rejected (grammatically incorrect, not embedded in relevant literature, ad-hoc and nonsensical analysis decisions); the decision was "minor revision" based on ONLY my review. How!?

Is the AI bubble bursting? Maybe for ChatGPT, but there is now widespread support for automating everyday tasks. Academics build small specialized models, trained on high quality data, informed by domain knowledge. It's time to incorporate these into everyday workflows instead of "asking ChatGPT".
