🚨 Now out in Nature Human Behaviour 🚨 We show that following the news on WhatsApp or Instagram (N = 3,395 🇫🇷🇩🇪) increases current affairs knowledge, participants’ ability to discern true from false news stories, awareness of true news stories, as well as trust in the news. doi.org/10.1038/s415...

I am now 2 for 2 on fact-checking products I helped build at large tech platforms that were killed this year. If you are looking for someone who can help you launch short-lived anti-misinformation efforts, look no further! indicator.media/p/google-kil...

100% what Roth says here www.insidehighered.com/news/faculty...

Not sure what to do about the fact that this country’s latest illegal war is being waged by a presidential administration that consists, top to bottom, of people who lie about everything, all the time

A key takeaway from 20+ years of computational RL is: model-free=automatic, model-based=deliberate. My new paper w/ @benedek.bsky.social challenges this view, suggesting that MB algos are more ubiquitous, & automatic processing more sophisticated, than currently thought: www.pnas.org/doi/10.1073/...

Republicans in congress are banking on not being held accountable for what Trump decides to do. The assumption is that the American public is not going to notice/understand/care that they're abdicating on their responsibilities. I'm curious what people think: Is this a sensible assumption?

We are hiring, @arc-mpib.bsky.social a postdoc for a project to investigate why citizens feel alienated from liberal democracy and how a shared sense of reality can be restored. Work with @lfoswaldo.bsky.social @anaskozyreva.bsky.social, Ralph Hertwig and me: www.mpib-berlin.mpg.de/2084802/2025...

Nice to see a replication in a sizable Chinese sample of @gordpennycook.bsky.social and my work on accuracy prompts reducing misinformation sharing! www.nature.com/articles/s41...

🚨In PNAS🚨 The right often accuses fact-checkers of political bias But we analyzed Community Notes on Musk's X and found posts flagged as "misleading" are 2.3x more likely to be written by Reps than Dems! The issue is Reps sharing misinformation, not fact-checker bias... www.pnas.org/doi/10.1073/...

a nation on edge holds its breath as the former host of celebrity apprentice huddles with his advisors, the wrestlemania ceo and the former co-host of fox & friends weekends

Of course. Conspiracy believers tend to overrate their cognitive abilities & think most others agree with them www.psypost.org/conspiracy-b... Study: "This relationship with overconfidence was robust ... and it was strongest for the most fringe conspiracies" (by @gordpennycook.bsky.social et al)

the story today is of a profoundly low energy military parade being met with millions of americans in nationwide protests denouncing the dictatorial pretensions of the president

Holy shit, New York! Here’s the full view. #NoKings #50501Movement

Stop Looking for Red Lines. You no Longer Live in a Full Democracy It's going to be up to us to bring it back to life open.substack.com/pub/ryandeno...

Again, I have to ask, how could this possibly be worth the financial cost?!? Setting everything else aside, the economic argument here is surely weak.

This is a lie. We all saw the video. The Senator clearly identified himself, and he did not "lunge" toward anyone.   If these miserable propagandists will lie to you about roughing up a U.S. Senator in a room full of reporters, what won't they lie to you about?

Worth considering that one reason Bluesky doesn't always feel super fun is that current events are relentlessly horrifying and bad

The Declaration of Independence specifies 27 grievances with King George III, and I count at least 15 of them that Donald Trump has also committed in whole or in part. Particularly notable right now: "He has kept among us, in times of peace, Standing Armies without the Consent of our legislatures."

Psychological inoculation is a very popular intervention against online misinfo, but it hasn't been tested using real-world outcomes in realistic scenarios. In a new paper just published in PNAS Nexus, this is what we did: academic.oup.com/pnasnexus/ar... Short version: It didn't really work.

Watch me scramble in real time as I try to find the economic angle on the Musk-Trump tiff. (I think I found one, and the issues it highlights are terrifyingly important.)

Val Thompson (my UG advisor) & Jon Fugelsang (my PhD advisor) BOTH received awards from the Canadian Society for Brain, Behaviour, & Cognitive Science! I owe them my life. So glad that their many accomplishments are being recognized! www.csbbcs.org/awards/dr-va... www.csbbcs.org/awards/csbbc...

My Canadian university, Queen's, is offering TWENTY 4-year funded PhDs (40k CAD/yr) for a student of ANY citizenship who has been accepted at a top 100 US university but have had offer rescinded OR are reconsidering offer due to US policy. Details found here👇 www.queensu.ca/grad-postdoc...

Our recently published paper in Psychonomic Bulletin & Review on #reasoning styles and #belief in God is now featured by @psychonomicsociety.bsky.social! Thanks, Jonathan Caballero, for the interesting article. 📄 Read the paper here: doi.org/10.3758/s134...

In addition to everything else, there is no way this makes sense economically. Massive taxpayer dollars being spent on deporting working people that have the support of their local community. And, meanwhile, cancer research is being cut? Insanity.

Future historians will surely debate whether Trump & his team actually believed their own bullshit. Trump et al.'s info environment is so polluted that it's possible that they genuinely believe the budget will not increase the deficit. They seem abnormally willing to be spectacularly wrong...

Learned something new today: Zotero has a feature where it informs you if an article in your reference library has been retracted. Very cool!

New piece: Most Trump voters did not "vote to deport moms." They voted bc inflation was high under Biden, to deport criminals, or something else. Many do not support Trump's policies. Welcoming those voters back into the tent is key to future Dem victory. www.gelliottmorris.com/p/many-trump...

a society that wants to keep its most basic functions intact needs to discourage baldfaced lying, especially by authority figures

I would hope that, by this point, university leaders who are still "negotiating" with the administration have their eyes wide open about the fact that these negotiations are all in bad faith.
