Who is susceptible to misinformation? We looked at >60,000 people from 24 countries who took our MIST test. Key results: Gen Z are more susceptible & those on the extreme right (but they don't know it).

For all this Trump and Elon talk about EU censorship let’s look at World Freedom of Expression rankings. I see lots of European countries but the USA is nowhere to be seen in the top 20.

I imagine they’ll increase the fines and eventually threaten to shut off X in the EU until they pay.

Defunding the US government wasn’t sufficient. Elon now wants to dismantle the European Union.

Great article from @zionlights.bsky.social in the New Humanist on teaching children to think critically and how Finland is leading the charge. newhumanist.org.uk/articles/6482

OU has put the professor here on administrative leave:

The University of Oklahoma takes seriously concerns involving First Amendment rights, certainly including religious freedoms. Upon receiving notice from the student on the grading of an assignment, the University immediately began a full review of the situation and has acted swiftly to address the matter.
First, the college acted immediately to address the academic issue raised by the student. College leaders contacted her on the day her letter was received and have maintained regular communication throughout the process. As previously stated, a formal grade appeals process was conducted. The process resulted in steps to ensure no academic harm to the student from the graded assignments.
Second, the student reported filing a claim of illegal discrimination based on religious beliefs to the appropriate university office. OU has a clear process for reviewing such claims and it has been activated.
The graduate student instructor has been placed on administrative leave pending the finalization of this process. To ensure fairness in the process, a full-time professor is serving as the course instructor for the remainder of the semester.
OU remains firmly committed to fairness, respect and protecting every student's right to express sincerely held religious beliefs.
The UNIVERSITY of OKLAHOMA

A new paper shows how social media accelerates extremism by flooding users with emotionally charged, divisive content that algorithms naturally amplify, making extremist narratives far more visible, engaging, and persuasive than they would be otherwise.

Sander van der Linden @profsanderlinden.bsky.social · 13d

In a new paper we present a framework for thinking about online radicalization where some people acquire extremist beliefs on social media (path A) whereas for others SM simply reinforces existing extremist beliefs (path B). Both can lead to support for violence.

New study on LLMs shows that while LLMs & humans converge on similar judgments of reliability of news media, they rely on very different underlying processes.

In delegating, are we confusing linguistic plausibility with epistemic reliability?

new paper by Sean Westwood:

With current technology, it is impossible to tell whether survey respondents are real or bots. Among other things, makes it easy for bad actors to manipulate outcomes. No good news here for the future of online-based survey research

Sander van der Linden @profsanderlinden.bsky.social · 18d

Let’s hope that’s the explanation

Sander van der Linden @profsanderlinden.bsky.social · 18d

Just casually reading in the 2025 Edelman Trust Barometer that nearly a quarter (28-country average) seem to think that intentionally spreading disinformation (!) or committing violence (!!) is OK as a means to bring about societal change.

Yes the BBC edit was poor journalistic form but the research indeed shows that Trump's speech predicted riots, violence, and weapons use on January 6th.

Here's my top 5 ways to help friends & family falling down the conspiracy hole:

1. Prebunk - prevention is key

2. Validate their worldview first

3. Reiterate social consensus to highlight extremism

4. Involve ex-conspiracy theorists

5. Keep in touch & prevent isolation

I hear a lot about misinformation as a "symptom" of "distrust". Here we test this & find that while trust is important, it doesn't buffer: misinfo isn't mitigated by high trust. Both misinfo & distrust *independently* predict vaccine denial. It's a disease of its own!

But cognitive antibody generation can be measured both physiologically and with fMRI in a way that maps onto behavioral constructs so it's pretty concrete to me.
