π§΅on my new paper "Synthetic personas distort the structure of human belief systems" w Roberto Cerina I'm v excited about...
π¨ Do synthetic samples look like human samples?
We compare 28 LLMs to the 2024 General Social Survey (GSS) to find out + develop host of diagnostics...

My Quarto #rstats tip for big/complex papers is to set up R scripts that do data processing/modeling & save plots/outputs as RDS files. The Quarto can then load the RDS file & make any modifications to the ggplot2 object before plotting. This avoids unwieldy long Quarto docs /w complex caching.

9.2% of all citations go to just 0.32% of psychology articles.
To have the most impact, post-publication peer-review should focus on these influential articles with β₯30 citations per year.
@error.reviews will systemically sample from such articles.

The German left has lost its monopoly on class consciousness
The German radical right has mobilised around a working class identity that pits hard-working βmaker...
This is very interesting and more data-driven than you might think from the title. Also comes up with an actual idea what centre-left parties could do to build a new coalition. No idea if this would work, but at least it's something constructive #farright #Germany #btw25

The G.I. Bill, Standardized Testing, and Socioeconomic Origins of the U.S. Educational Elite Over a Century
Ran Abramitzky, Jennifer K. Kowalski, Santiago PΓ©rez, and Joseph Price
NBER Working Paper No. 33164
November 2024
JEL No. 123, 124, N32
ABSTRACT
We compile, transcribe, and standardize historical records for 2.5 million students at 65 elite (private and public) U.S. colleges. By combining these data with more recent survey and administrative data, we assemble the largest dataset on the socioeconomic backgrounds of students at American colleges spanning the last 100 years. We document the following: First, despite a large increase in the share of lower-income students in the overall college-going population, the representation of these students at elite private or public colleges has remained at similarly low levels throughout the last century. Second, the representation of upper-income students at elite colleges decreased after World War II, but this group has regained its high representation since the 1980s. Third, while there has been no increase in the economic diversity of elite private and public colleges, these colleges have become more racially and geographically diverse. Fourth, two major policy changes in the history of American higher education, namely the G.I. Bill after World War II and the introduction of standardized tests for admissions, had little success in increasing the representation of lower- and middle-income students at elite colleges.
Holy crap this is an astounding piece of historical research
Will post ungated link later today unless someone beats me to it

Two maps the the contiguous United States. The first is colored with the 4 time zones. Above that map states "say no to time zones". The bottom is the same map but with a continuous color gradient. Above that map states "say yes to the time gradient"
We must stand against the arbitrary categorization of continuous variables!
... and that's why I'm proud to announce my support of abolishing time zones in favor of the time gradient

An infographic of Taylor's thesis defense. Moves through and describes all 4 of her thesis papers. The title of her thesis was "Socio-ecological well-being: Resources at the personality,k activity, and community level (Taylor's version)"
My PhD student, Taylor Hill, successfully defended her thesis on Tuesday! She's not here on Bluesky, but one really cool thing she did was get an infographic of her thesis drawn live from the defense. It's so cool, I had to share.
Check it out, and the service she used is here:
