Scaling actually follows a log not exp function, so actually the exact opposite is more likely to be true

A good moment to advertise this week’s Rethink where we discuss the promise of AI with proponents and skeptics alike and I make a bad stochastic parrot joke. With @emollick.bsky.social Rosalind Picard, Mike Wooldridge and more.

But, I think @damonberes.com is right.

In 2022, Michael Rochlitz and I designed a survey experiment about government surveillance tracking protesters. Back then it was hypothetical.
ICE is now doing exactly what we described.
New post on what our data showed and why privacy is a political question.

Call for Proposals: Data Collection for
Replication+Novel Political Science Survey Experiments
Alexander Coppock and Mary McGrath
January 27, 2026
We invite proposals for a survey experiment replication+novel design competition. Se-
lected replication+novel design survey experiments will be conducted on large samples of
American respondents, quota sampled to match U.S. Census margins and filtered for quality
and attention by the survey sample provider Rep Data (repdata.com).
Each proposal consists of two parts: (1) a replication study of an existing, previously
published survey experiment, and (2) a novel experimental design on a topic of the authors’
choosing.
The replication studies and reanalyses of the existing studies will be combined into a
meta-paper to be co-authored by all authors of accepted proposals along with the princi-
pal investigators (Coppock and McGrath). As a condition for acceptance, authors commit
to sharing the data and producing a write-up of the findings from their novel design for
submission to a scholarly journal, and public posting of a working paper pre-publication.

"the relationship between downward class mobility is only mediated by life satisfaction and income insecurity, suggesting that the class route to far-right voting is largely linked to existential and material issues. "

People misperceive their rank in the wealth distribution: the wealthy underestimate how much they have compared to others, and people at the bottom of the distribution think that they are doing better compared to others than they actually do. Our research shows that misperceptions shape for savings.

Very interesting thought. Analogously, the BBC staying on X might boost its value for users while also needlessly legitimazing it
