Information manipulation is going to get cheaper much faster than interacting with the world will. I expect that this will lead to the bottleneck in research shifting from production to consumption. We should be preparing for this shift now by building infrastructure that allows us to adjudicate claims and filter work in a world where production is cheap. The current journal system is not well positioned to do this, and so we should be experimenting with new institutions that can.

I'll be at a workshop organized by @rohanalexander.bsky.social next week on how AI will change quantitative social science. This is my short paper, and this is the key argument. ryancbriggs.net/blog/as-ai-l...

I think the issue is that two claims get conflated:

"Statistical learning over massively distributed representations is more similar to neural processing than symbol manipulation is"

"Connectionist / Neural Networks / Deep Learning / Transformer models are just like humans"

Sounds interesting. Have you read any of Greg Egan's stories exploring possible selves? The Infinite Assassin in _Axiomatic_ seems particularly closely related.

AI seems to be the topic of the year — nearly every conversation I have in my role as academic lead for good research practice touches on it in some way. I’d like to lay out my developing thoughts for conversation and critique. (1/7)

I've been doing a lot of Mad Libs with my son lately, and I thought it would be fun to put one together with a data management theme.

“Kings had always been involving and impoverishing their people in wars, pretending generally, if not always, that the good of the people was the object,” a young representative named Abraham Lincoln wrote in 1848. This was “understood to be the most oppressive of all Kingly oppressions and they resolved to so frame the Constitution that no one man should hold the power of bringing this oppression upon us.” This quote, incidentally, is immortalized on the House’s website, if any members of Congress are looking for it.

In fairness it’s not like the consequences of having a mad king unilaterally take the country to war on a whim were so incredibly obvious that you could see it coming from the 18th and 19th centuries www.theatlantic.com/ideas/2026/0...

I just posted a new essay, forthcoming in the Florida Law Review, on Retrospective Surveillance. It focuses on geofence searches and how to assess them, in anticipation of the upcoming huge Supreme Court case on geofences.

given the modern conservative fascination with Sparta it's at least a little funny that they've engineered a situation in which Persia is able to level a dramatically uneven battlefield by forcing the conflict into a narrow pathway

A comment on Research Gate notes that it is roughly consistent with this calculation of cognitive control capacity as 3-4 bits per second.

Ok I'm in a rabbit hole. If you search "how many decisions do we make in a day" the reported number is almost always 35,000, often reported that this is according to "multiple sources". Yet I can't actually find a single source that backs up that number. Anyone know where this number comes from?

A long time ago, I used to know a lot about foreign-imposed regime change (FIRC) and study them.

I guess that makes me qualified to write a thread about them, especially in wake of Trump bombing Iran.

So here goes nothing. 🧵

My new book on fairies (out next month) deals with homunculi as a kind of fairy - or, at least, as fairy-adjacent beings. I'm just a bit worried that the popularity of 'Small Prophets' could lead to a spate of people trying to make them, without the proper skills or preparation
