Funny enough, when talking about the replication crisis in grad school, I remember saying to my advisor that if the original dissonance paper turned out to have been totally fabricated, it wouldn't matter. No one study should carry a theory.

there was some discussion on here recently about the scientific legitimacy of cognitive dissonance research. as someone who has spent years investigating this literature, i wanted to make a thread to explain why pessimism is not justified by careful inspection of the evidence

There’s growing evidence that something was going seriously wrong in the classic early work on cognitive dissonance

Can LLMs stand in for human respondents? We highlight some ways to consider the data in the context of moral judgments.
Out now in Scientific Reports! Despite high correlations, ChatGPT models failed to replicate human moral judgments. We propose tests beyond correlation to compare LLM data and human data.

I'm excited to share that I’ll be reviewing PhD applications this cycle for students interested in working with me starting Summer/Fall 2026.
I’m especially looking for applicants excited about research on trust/persuasion, responses to historical harm, addressing inequality, and/or mindsets.

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.

It’s here! Such a thrill to hold the book in my hands: “The Communicating Scientist” with my illustrations inside. It’s the kind of book I wish I had when I was a PhD student, and I’m glad to have it as a reference as a communications professional #SciComm 🧪

It's to the point where I'm kind of excited when a student's answer isn't perfect because it means they probably actually tried to answer the question themselves instead of leaning on AI.

Why does wealth inequality matter to you? Because when anyone has more money than they can spend on staples, and even on luxuries, they have to buy assets. Stocks, real estate, and higher education for their children. We've lived with massive inflation in these three categories for decades.

Hey! Public radio is defunded but not defeated. An NPR friend told me that since the defunding, the public has been stepping up in huge numbers. We can make public media even stronger and better.

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...
