Why do arguments often change people’s beliefs without changing their attitudes? In a new APSR with @PatrickPLiu and Scott Clifford, we point to belief relevance: arguments are more persuasive when they grapple with the idiosyncratic reasons people hold their political views.

**Personal Finance Notes for New Faculty** I intentionally chose a red day to post this, to avoid giving the impression that I am encouraging people to buy stocks.

In 2020, I wrote a short note on personal finance for a Chinese-speaking young faculty audience and have updated the numbers since then. Ye said this is my most-read piece of writing. 🤣

This is the English version.

Over the years, I have also given many of our international students a 30-minute tutorial on this topic when they start academic jobs in the US.

They are excellent at what they do, but knowledge about US financial markets is often lacking. I hope this helps.

🚀 Big update for the did R package!

The headline: it is much faster ⚡

We also improved support for many things, including:

✅ clustered inference
✅ unbalanced panels
✅ factor/transformed covariates
✅ lots of fixes under the hood

“Just collect more data” is one of the most common responses to uncertainty in quantitative research.

But in a lot of social science, that advice is impossible—or even misleading. Our new working paper asks: when has a study reached its information limit?
