I ran a simple model with new public data then used 1 prompt to make ChatGPT guess what the model would produce. With 10 seconds of "thinking," it was very close. The implications of this are catastrophic. The American Sociological Association should do something about this but it doesn't care to

Schweden wäre so ein negatives Beispiel wo Einkommen noch stärker und Vermögen noch weniger (so gut wie gar nicht) als in D besteuert wird. Mit der Folge dass die Vermögensverteilung in ihrer Ungleichheit nur von den USA überboten wird. Allerdings sind die staatlichen Finanzen (noch) gut

Compared with a year ago, White Protestants and religiously unaffiliated adults now have significantly less confidence that Trump acts ethically in office.  For example, 26% of White nonevangelical Protestants are extremely or very confident Trump acts ethically in office, down from 38%.  And the share of religious “nones” who have a lot of confidence in Trump’s ethics now stands at 10%, down from 16%.  Confidence in Trump’s ethics has remained low among Black Protestants.

The social media ban that wasn’t — Crooked Timber The Australian government’s legislation seeking to ban access to social media for people under 16 has received plenty of attention in International media, mostly leading with the government’s that 4.7 million accounts were banned or deactivated when the legislation came into effect. Rather less attention has been paid to discussion of the outcome within Australia, where the consensus is that there has been very little effect for most. With most kids still active, the minority who have been caught by the ban have suffered feelings of ostracism and exclusion When discussing the issue on my own social media (which had few if any teenage readers to begin with) I’ve only had one parent report their kids being thrown off.

But, but, the headlines said the effects occurred overnight and were so positive that Australian parents hardly recognised their sullen teens?

Figure 1 from the paper. Econ: from 2008 to 2024, methods aiming for causal inference have increased, theoretical work has decreased. Psych: Mostly experimental or descriptive correlational work.

Just learned about this study looking at methodological trends in psych and econ over time: online.ucpress.edu/collabra/art....

Matches my perception well: Nobody in psych bothers to (explicitly) try causal inference unless they conducted an experiment, not a lot of theoretical work either.

Insane! At all levels, really. First of all, they have nothing to do outside of the U.S. Second, they are among the worst-trained of the dozens of security and law enforcement services the U.S. has.

What this shows, however, is that the Trump Administration sees ICE as its personal military.

Another update on American Sociological Review’s failure to meet current social science standards In the most recent volume, two-thirds of papers based on quantitative analysis provided replication packages.

Two-thirds of quantitative articles in the latest volume of American Sociological Review provide at least their code and a link to the data, which is progress over past years but still very bad.
