Put simply:

Humans: weak, multi-dimensional, cross-cutting belief systems.

LLM personas: concentrated, low-dimensional, highly predictable.

Not just stronger ideologyโ€”flattened geometry.

We usually think that social identities precede preferences

We show the reverse is also true: people update their social identities to match their immigration preferences

Focus: class identity in ๐Ÿ‡ฌ๐Ÿ‡ง + Christian identity in ๐Ÿ‡ฎ๐Ÿ‡น

Is online discourse getting worse?

To bring actual data to bear on this question, we launched the Public Discourse Indicator, a dashboard tracking online comments submitted to several major Swiss newspapers. Our aim here is twofold:

The finding: voters' changing preferences do not translate into voting intentions.

Instead, I suggests that voters do not experience substantial cognitive dissonance when their party's position differs from theirs, and generally tolerate mild disagreements with their party's position.

In the study, I exposed voters to news articles that shifted their views on a policy issue, then showed them their preferred party's (or another party's) position on that same issue. I measured how their attitudes and voting intentions changed.

I hypothesized that voters would either

(1) adjust their own views to match the party, or
(2) adjust their party preference to match their views.

Specifically, I expected partisans would shift their attitudes toward their party's position, while non-partisans would shift their voting intentions.

What happens when voters learn their party disagrees with them?

I ran a pre-registered experiment with a representative sample of ~3,000 German voters to find out.

Labour is desperately trying to appeal to Reform supporters. In October, we asked people in the UK if they perceive a party as a "party for someone like them". Only very few people say this for both Labour and Reform. The correlation is negative. Labour is chasing an electorate that does not exist.

This! ๐Ÿ‘‡

It is also a good reminder that we are not experiencing polarization but right-wing radicalization!

Die Frageformulierung ist so natรผrlich schon komplett bodenlos. Aber es dann so verkรผrzt darzustellen ist schlicht Irrefรผhrung. Vollkommen inakzeptabel.

"normies do not care about this thing and so it is no use raising a stink" is imho just an excuse for not doing politics, which is the job of making normies care about something

Literally: This. Is. How. It. Happens.

Especially pernicious because the effects are largely invisible even as they accumulate. It just seems like the opposition is weak and ineffectual; you never see what people would have said and done if they weren't threatened and intimidated.

Again, it is a full-blown federal felony crime for anyone in the White House or Executive Office of the President to order tax investigations into anyone.

And it's not just a crime to DO it, it's even a federal crime for an employee not to REPORT such an order to the Treasury Inspector General.
