I’m so glad to see more attention being paid to the data being used to train AI models. The results will only be as good as the data going in.

Dozens of AI disease-prediction models were trained on dubious data. The models are designed to predict someone’s risk of diabetes or stroke. A few might already have been used on patients. www.nature.com/articles/d41...

Loved this episode of reflection, especially @publichealthpod.bsky.social as a podcast asking and answering questions, with experts from a range of fields who are consider multiple angles and dig into the evidence. Conversations and sources of information like this are more important than ever.

So fun to come across this! It has been an honor and joy to work with Grace on topics that include proximal causal inference, electronic health records, and measurement error. She is a careful and excellent researcher, and an amazing team member!

This Radiolab episode is one of the most beautiful and moving pieces of science communication I've come across in a long time. Do yourself a favor and take some time to listen to this story of astrophysicist Charity Woodrum, and what she's learned from her work and life radiolab.org/podcast/gala...

I appreciate the push for research at the end of the story about AI + education. But it doesn't clarify who will pay or do that needed research -- with the gutting of the federal education research agency (IES) it's not clear there will be unbiased groups to do it. www.nytimes.com/2025/07/09/b...

I am grateful for this coverage. Fiona is a friend and sadly just one example of many devoted public servants (who I know personally to be deeply committed, smart, and caring) whose expertise we are currently losing from the government.

Profile and interview of Fiona Havers by @apoorvanyt.bsky.social now out in the NYT. A must-read on the loss of experts and expertise. 🎁 link www.nytimes.com/2025/06/18/h...

@noahgreifer.bsky.social was my post-doc and I cannot recommend him more highly if you need a super smart statistical consultant / programmer. He is the force behind MatchIt, cobalt, and other packages, and is also just a fantastic team member.

Noah Greifer@noahgreifer.bsky.social · last yr.

Starting to look like I might not be able to work at Harvard anymore due to recent funding cuts. If you know of any open statistical consulting positions that support remote work or are NYC-based, please reach out! 😅

Excited for what will be a flash trip to New England in mid-June for the AI + precision medicine conference in Portland, ME, followed by the Society for Epi Research in Boston! Join me at both!

Great way to learn the basics of policy trial emulation and the importance of careful study design for health policy!

If you missed the latest Advanced Methods for Mental Health Services Research Webinar, "Target Trial Emulation for Evaluating Mental Health Policy" from Nicholas J. Seewald, Ph.D., don't worry! You can watch it on the JH ALACRITY Center's YouTube channel: youtu.be/DAXfp8X9ba8?...

This is so important. And especially in non experimental studies where bias - not variance - is the first order concern.

Adam Kucharski@adamjkucharski.bsky.social · last yr.

The larger the dataset, the larger the false sense of confidence - if bias is baked in, size just makes a flawed measurement more convincing. Xiao-Li Meng has called it the big data paradox: 'The bigger the data, the surer we fool ourselves.' In other words, scale isn’t a substitute for scrutiny.

This has been one of the most meaningful and rewarding (and sobering) collaborations I have been involved in, especially the integration of advanced stat methods and deep substantive expertise. Crucial empirical data and results that we hope can inform policy discussions.
