I'm super excited to announce that ISBA @isba-bayesian.bsky.social has voted to start a new section on Bayesian Social Sciences! It will be a great way to further collaborations with many disciplines in the Social Sciences and Humanities. bss-isba.github.io

The new Bayesian Social Sciences section of @isba-bayesian.bsky.social has just been created: bss-isba.github.io. The committee is myself as chair, @robinryder.bsky.social, chair elect from 2027, @nialfriel.bsky.social, program chair, @monjalexander.bsky.social, Treasurer, EJWagenmakers, Secretary.

The data is now available for all teams who've already signed up! More sign-ups very welcome! Happy analysing! 💻📊

GPT-5 regularly asks you why you are not citing its work. GPT-5 always believes your estimator is biased. GPT-5 has more of a comment than a question. Sometimes GPT-5 tells you stories about grad school and expresses regret about getting a PhD. GPT-5's mom wonders when it will start making money.

Average mortality rates are a horrible measure of typical mortality during the first weeks of life. On the day of birth modal mortality is 189 times lower than average mortality. Read more in my recent piece on selection in neonatal mortality.

Mifepristone is one of the most studied, safest medications in use today — over 20 years, 100+ studies, millions of patients. Attacks on mifepristone aren’t science — they’re ideology. Let doctors and patients lead, not politics.

It´s happening and @hggaddy.bsky.social is discussing, among other issues, how temporal disaggregation for time series analysis of mortality is a solution for a need for spatial disaggregation - which creates death toll underestimation!

Monash University has made many positions available specifically for young and early career researchers who would like to take some time away from the USA. These are case by case, not advertised. So if you are interested or know anyone interested have them get in contact with someone at Monash.

NEW: In agency after agency, the U.S. government is losing its capacity to measure how American society is functioning, making it much harder to gauge the nature and scale of the problems we are facing and the effectiveness of policies. By @alecmac.bsky.social

It is an honour to receive this award with a group of scholars I admire. I'm not sure what I'll be talking about at the ceremony yet, but it's likely I'll go a bit off script and talk about the importance of the DHS and other surveys in measuring demographic outcomes.
