Sharing our new paper here! People talk about how deepfakes propel us into the post truth era, and we provide some empirical evidence for this: “People are more susceptible to misinformation with realistic AI-synthesized images that provide strong evidence to headlines”

Does AI improve or undercut academic scholarship? A new study finds that academics who use AI increased both the quantity & quality of their academic scholarship and it appears to reduces inequality (helping junior and non-english speaking scholars the most). arxiv.org/pdf/2510.02408

Social scientists should not use chat interfaces when using LLMs in their research: they are impressively inefficient, and obscure/impose important methodological decisions that require thought. THREAD🧵

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.

Perhaps unsurprising given I research misinfo interventions, but I strongly disagree with this article. If you thought that small tweaks were going to fix the misinfo problem, then yes, you'll be disappointed. But, come on, we all know there is no magic bullet. 1/ www.nytimes.com/2024/07/11/t...

At a time when scientific misconduct is making headlines, the truth is that errors in science are largely brought to light by unpaid volunteers. I wrote about a new program that wants to shake up those incentives and pay sleuths cold, hard cash for finding mistakes. www.chronicle.com/article/want...

To any misinformation researchers out there: do you read or rely on any cog sci or neuro papers about learning and memory? For example, how relevant is the classic AB-AC memory updating paradigm to correcting misinformation?
