Does this graph surprise you? I'm actually encouraged by the large percentage of U.S. adults who read at least one book each year.

With everything going on, it's easy to forget that immigration reform can fail EVEN IF a majority says it's "for" it.
Politics runs on attention, and immigration supporters often care less about it than opponents. My new paper in @poppublicsphere.bsky.social tries to address this gap.

'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!

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.

Insightful take on the conversation regarding dissonance.
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

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.
