This month on Opinion Science, I talk with @steverathje.bsky.social about his research on the "psychology of technology." We cover the predictors of what goes viral online and the allure and influence of agreeable AI chatbots.

A couple of years ago, I made these nerdy romantic cards in my basement print shop. I still have a few left for anyone looking to send a message this Valentine's Day, grounded in behavioral science.

Is a bowl of cereal with milk a type of "soup"?
It turns out that categories don't have the neat rules we assume they do.

They are all printed with old methods, including vintage metal and wood type, which are physically inked and pressed onto paper using antique presses. It's mechanical, it's tactile. Nary a computer screen in sight.

'Tis the season, etc. If you know a nerd who has it all, do they have letterpress posters with motivational science messages?
I've built an old-timey print shop in my basement where I use old printing presses to make modern prints. And you can purchase them!

Early Christmas present! For the last couple of years, I have been helping to update this textbook for a new edition. I joined a great team that had written the original book, and together we thoroughly revised it and updated it with new research and examples. My copies arrived just the other day!

I really enjoy starting the work day with just myself, a cup of coffee, and a typewriter. Like many people, I'm easily distracted by the vastness of the internet. It's hard to focus on thinking through a problem or idea. These 100-year-old suckers help me slow down and just get thoughts on paper.

Bluesky has not yet been affected by my new obsession with mechanical typewriters. So, here. From my new morning routine, a delightful and refreshed 1937 Remington 5.

Opinion Science is back from its summer break, and I'm happy to share this conversation with @dbroockman.bsky.social.
We discuss why it’s so hard to predict which messages will work + the gap between political insiders’ instincts and what actually resonates with the public. (Links in comment)

I've got to say that I'm loving Underwood's branding: "The Machine You Will Eventually Buy."
It feels like very snarky social media messaging except in the very early 1900s.

She discusses interview strategy, science's role in storytelling, & producing science radio for kids...

Are you teaching behavioral economics this semester?
Just a reminder that I produced a 5-episode podcast series with Behavioral Grooves on the origins, growth, and future of behavioral economics.
AND we developed some helpful note-taking and discussion guides for use in the classroom...
