A Max Planck research group will launch on April 1, 2026, focusing on reproductive aging and its social implications.

Max Planck Research Group on Reproductive Ageing, led by D. Susie Lee 이수지, is starting today! It will investigate indicators of female & male reproductive ageing: www.demogr.mpg.de/en/news_events_6123/news...

And why should sociology be GenEd? Because it’s our job to make social patterns visible to students. Things are happening in ways that influence all of our lives, whether people see them or not.

I see quite a few demographers with exploited works that are owed part of the Anthropic settlement. Too many for me to give individual heads-ups to. Worth your time if you’re one of them.

Data Visualization A Practical Introduction

Here’s a full draft of the upcoming second edition of my “Data Visualization: A Practical Introduction”: socviz.co

Clinical trial reforms that once seemed radical How randomized controlled trials, preregistration, and results reporting became standard practice.

New post!

It may seem ambitious to ask for individual patient data from clinical trials to be shared, anonymized, for use by other researchers.

But the history of medicine shows us that clinical trials have already undergone a series of transformations that once seemed equally bold:

The political effects of X's feed algorithm https://doi.org/10.1038/s41586-026-10098-2 Received: 16 December 2024 Accepted: 4 January 2026 Published online: 18 February 2026 Open access • Check for updates Germain Gauthier,5, Roland Hodler?5, Philine Widmer35 & Ekaterina Zhuravskaya3,4,5 m Feed algorithms are widely suspected to influence political attitudes. However, previous evidence from switching off the algorithm on Meta platforms found no political effects'. Here we present results from a 2023 field experiment on Elon Musk's platform X shedding light on this puzzle. We assigned active US-based users randomly to either an algorithmic or a chronological feed for 7 weeks, measuring political attitudes and online behaviour. Switching from a chronological to an algorithmic feed increased engagement and shifted political opinion towards more conservative positions, particularly regarding policy priorities, perceptions of criminal investigations into Donald Trump and views on the war in Ukraine. In contrast, switching from the algorithmic to the chronological feed had no comparable effects. Neither switching the algorithm on nor switching it off significantly affected affective polarization or self-reported partisanship. To investigate the mechanism, we analysed users' feed content and behaviour. We found that the algorithm promotes conservative content and demotes posts by traditional media. Exposure to algorithmic content leads users to follow conservative political activist accounts, which they continue to follow even after switching off the algorithm, helping explain the asymmetry in effects. These results suggest that initial exposure to X's algorithm has persistent effects on users' current political attitudes and account-following behaviour, even in the absence of a detectable effect on partisanship.

A new paper shows that less than 2 months of exposure to Twitter’s algorithmic feed significantly shifts people’s political views to the right.

Moving from chronological feed to the algorithmic feed also increases engagement.

This is one of the most concerning papers I’ve read in awhile.

The last part abt how measles disrupts immunity vs other infections is, imo, underappreciated (& mechanism was recently clarified). It's part of why measles vaccination was seen to help beyond just reducing measles complications - not getting measles reduces severity of subsequent infections too.
