After five years of work, I finally held a copy of my book Misguided—a surreal moment and long-time dream come true. The book explores the psychology of misinformation and is now available for preorder; I’m also booking podcast interviews and talks to support the launch. #BookSky #Misguided

“With COVID, vaccines, Lyme disease, any of it — I’m not your enemy,” I told my seatmate as we were getting ready to disembark. “And I know you’re not the enemy, either.”
“True,” he agreed. “But they always want to make someone your enemy.”

Can we actually train ourselves to be more open-minded and harder to fool?

New research says yes. A short message warning us about closed-mindedness made people better at spotting misinformation, less likely to believe conspiracy theories, and more thoughtful about what they shared #MisinfoResearch
How to Train Yourself to Be More Open-Minded and Less Easily Misled
New research shows that cultivating open-minded thinking can be taught, and that this simple shift improves our ability to tell facts from falsehoods.

New research found that belief in conspiracy theories is linked to a mix of perceived unfairness, bitterness, and suppressed anger. People who experience these feelings are more likely to reject the status quo and embrace conspiratorial explanations.

The ‘sour grapes’ of conspiracy theories: how does the emotion of ressentiment predict conspiracy beliefs? - Acta Politica
This research examines how negative emotions affect the degree to which people endorse conspiracy theories. Conspiracy beliefs typically flourish in contemporary politics that evoke negative emotions. In the present article, we hypothesized that citizens in ressentiment, a particular emotional state salient in contemporary grievance politics, is a key underpinning of why people believe in conspiracy theories. Ressentiment is a multi-layered emotion, within which perceptions of unfairness, bitterness, and feelings of (suppressed) anger are central. Across three studies, we examined the role of ressentiment in predicting belief in conspiracy theories. Study 1 (United Kingdom, N = 300) and Study 2 (United States, N = 300) revealed a positive relationship between ressentiment, measured through a validated scale, and belief in conspiracy theories. This relationship was mediated by rejection of the status quo. In Study 3 (United States, N = 300, pre-registered), we used a vignette describing a fictitious country to experimentally show that evoking ressentiment (vs. control condition) significantly increased belief in conspiracy theories. Taken together, these findings reveal that ressentiment is central for understanding the emotional roots of believing in conspiracy theories.

A new study finds that participation in Community Notes on X is declining, with fewer contributors sticking around and fewer notes being published. The rise of AI-generated notes may worsen these trends by overwhelming the system and reducing incentives.

“Through a critical review of the current literature, we demonstrate that (a) the prevalence of misinformation is nonnegligible if reasonably inclusive definitions are applied and that (b) misinformation has causal impacts on important beliefs and behaviors”

This was exactly what I was worried that could happen, and this new study (although not peer-reviewed yet) confirms what I would have predicted.

This paper describes a fun media literacy classroom activity where students form groups to create and present media literacy solutions, each secretly weaving in either facts, emotional appeals, or misinformation, while a panel of peers judges their work.
