Do allies and adversaries shape U.S. views on cyber attribution? In a new paper at @intlinteractions.bsky.social, I show that allies’ endorsements boost Americans' trust in attribution and support for retribution, while adversary denials produce limited and inconsistent effects.
Blame Games in Cyberspace: How Foreign Cues Shape Public Opinion on Cyber Attribution and Retribution

I’ve long used FiveThirtyEight’s interactive “Hack Your Way To Scientific Glory” to illustrate the idea of p-hacking when I teach statistics. But ABC/Disney killed the site earlier this month :(

Great essay on why we should be paying more attention to attention in our information-rich era.
The attention economy is devouring politics. Social scientists need to understand how. As do we all. www.programmablemutter.com/p/the-attent...

Last week in my Cyber Policy & National Security class, students mentioned DOGE's access to federal systems, which led us to discuss some cyber vulnerabilities. This week, I’m referring them to @profsaunders.bsky.social & @jimgoldgeier.bsky.social article in @foreignaffairs.com. It's a must-read!

This! Since moving back to the U.S., I've gained a few pounds. Same diet (we cook almost everything from scratch), but now I drive everywhere. In Rio, I walked and took public transit all the time. Big difference!
Americans will go on vacation to a place that isn’t a car sewer, walk and take public transit for 8-12 hrs. a day, notice a change in their health, and attribute it to “they must not have the Illuminati chemicals here”
Ainsley Earhardt makes a case for RFK Jr: "When you go to Europe, the food is delicious. It's so fresh. And you don't gain weight if you eat a big bowl of pasta. So we want that to come here to America."
