Lots of policy. No politics.
I'll create a bot account which will just retweet this every day, in 50 languages
Feels like so many of our convos are revolving about how voters respond to what politicians are doing, or what parties’ positions on issues are, without much actual empirical sense of what they actually know about those topics.

I don't think this is true at all. Most of the information we have on anything comes from text, and a textual "deepfake" has always been as easy as a true one. Yet for all the talk about misinformation, the information system in place works generally well. It relies on a network of trust.
I think people are still unprepared for a world where you cannot trust any video content, despite years of warning.
Even when Google & OpenAI include watermarks, those can be easily removed, and open weights AI video models without guardrails are coming. www.404media.co/sora-2-water...

Sora 2 Watermark Removers Flood the Web
Bypassing Sora 2's rudimentary safety features is easy and experts worry it'll lead to a new era of scams and disinformation.

Yes! And appropriately enough, central planning built an insanely expensive project that was largely to impress other nations.

"PhD-level experts in your back pocket" is a completely nonsensical description of AI but a pretty good description of social media if you follow the right people

Are there still political scientists who (i) are small-d democrats and (ii) would recommend presidentialism over parliamentarism for a country (re)drafting its constitution?
Recommendation might be in general or in specific circumstances?

There are different ways voters can be rational or not
The rationality hypothesis works sufficiently well for some types of choices, terribly for others

Traditionally, social psychologists saw obedience as central to the conservative mindset. Recent research, however, suggests that liberals are just as obedient as conservatives, but just to different authorities. www.stevestewartwilliams.com/p/12-things-...

A good illustration of why using net present value is better than cost benefit ratios
Infinite! That’s a lot.
Updated paper: A lot of work on the effects of tracking in education, which is a widespread practice globally. We show 1) algorithms can track students far more effectively than test scores 2) test scores discriminate 3) algorithmic placement has infinite MVPF static1.squarespace.com/static/60d0c...

It’s widely accepted *that* less expensive housing markets see less homelessness, but this important piece shows *why*: family & friends have more space to spare worksinprogress.co/issue/why-ho...
Why housing shortages cause homelessness - Works in Progress
Why do high-cost cities have more homelessness? It's not just about rents — it’s also about the rooms friends and family can’t afford to share.

I also experienced the shift yesterday, when following news about South Korea
I know it’s not quite a controlled experiment but today was the first time I’ve posted a set of links here and the Xbirdsite at the same time, and experienced more immediate reaction here than there. So the shift seems to have occurred, at least from my own narrow perspective.

Fully agree "constraints on the executive" is bad proxy for good institutions, but that is because it is bad terminology.
Institutionalists mean "responsibility to parliament" when they say that. As Gabriel notes, though, there are several ways one can design constraints on the executive.

This is a thread of comment and critique of AJR (recent Nobel Prize Winners) and the other institutionalists who use a “constraint on the executive” variable proxying for “good” institutions. I am not a medievalist or political theorist, doing my best- I appreciate critiques and criticism. 1/N
