How appealing an explanation is, is only in part down to how well it actually *explains*, research by klopfenstein.bsky.social & @hugoreasoning.bsky.social suggests.

Usefulness and surprisingness matter too, the latter especially explaining why poor explanations become popular:

Copy Editing Matters, from HHS's release on the new childhood vaccine schedule: All the diseases will still be available to anyone who wants them
Ensures that all the diseases covered by the previous immunization schedule will still be available to anyone who wants them through Affordable Care Act insurance plans and federal insurance programs, including Medicaid, the Children’s Health Insurance Program, and the Vaccines for Children program. Families will not have to purchase them out of pocket. Among peer nations, the U.S. will continue to offer the most childhood vaccines for free to those who want them.

Why do humans have linguistic intuition? And why should you care?

A short thread about my new paper in @cadlin.bsky.social

This work has the most original insight I've ever had, a genuinely new idea about the nature of language

Woah.

Argentina's 1990s preschool expansion program appears to have been a smashing success.

The program increased high school completion by a whole 11.9 percentage points.

The authors estimate that for every $1 spent, the preschool expansion generated about $11 in benefits.

The "smartphones/social media" discourse suffers from some amazing historical amnesia. There was no 2008 financial crisis and no global pandemic starting in 2020, it's all SCREENS SCREENS SCREENS. Major world events? Just the backdrop against which SCREENS happened.

The Center for Information Technology Policy at Princeton invites applications for a Postdoctoral Fellow to work with an interdisciplinary team (me, @bstewart.bsky.social, and @manoelhortaribeiro.bsky.social).

Link: puwebp.princeton.edu/AcadHire/app...

Please apply by THIS SUNDAY, Dec. 14!
We are seeking a Fellow to lead cutting-edge research on short-form video content and its societal implications. Bridging the gap between computer vision, causal inference, and computational social science, the Fellow will focus on the large-scale analysis of TikTok data (using an existing, massive dataset). The position involves developing novel multimodal methods to understand how short-form algorithmic content shapes public opinion, political polarization, and online culture. This is a unique opportunity to work at the forefront of the field, combining rigorous social science research designs with state-of-the-art computational techniques.
