So many of my friends wrote great books in 2025! Here are over a dozen photos I took this year to celebrate newly released behavioral science books. Congratulations all 🎉

So proud of the brilliant, amazing and delightful @hengchen_dai ❤️🎉

My dear friend and co-author @R_Thaler had his account hacked and now he’s locked out. He hasn’t been able to get through to @X. @elonmusk plz help he drives a Tesla!

Is winning an auction always truly a win? Nobel Prize–winning economist @R_Thaler explained the origin of "The Winner's Curse," the title of his newest book with co-author @AlexOlegImas, during a @BehaviorChange event moderated by @AngelaDuckw and @Katy_Milkman.

This December, >2 dozen podcasts are joining forces to raise $1M for 700+ families living in extreme poverty across 3 villages in Rwanda. I'm proud to be supporting this #PodsFightPoverty effort in my capacity as host of #Choiceology (and joining other great hosts I admire like

How can understanding “friction” in decision making help you break bad habits and reinforce good ones? I’m delighted to share a Q&A with the brilliant psychologist and best-selling author Professor Wendy Wood on this topic in the latest Milkman Delivers!

NEW with @evavivalt on forecasting social science. Results from the first 100 papers on the SSPP. Do people overestimate treatment effects? Are some predictors more accurate? Can forecasts be used for power calcs? Read on! @katy_milkman @Devin_G_Pope @lkatz42 @betsylevyp

It wouldn’t be the ⁦@SJDMOfficial⁩ conference without a family dinner! I love this annual tradition of a meal with all of my current and former ⁦@Wharton⁩ PhD students and my students’ students. Thanksgiving came early for me ❤️

We enjoyed a lively conversation between @katy_milkman, @femonomics, and @juddkessler about how behavioral economics can help people get more out of life. We’re glad so many people joined us for this event!

See 29:40 for when @katy_milkman made me explain how concavity generates risk aversion in Expected Utility Theory and why it can't explain risk aversion over small-stakes....without a whiteboard or slides! A lot of hand motions were made.

I'm excited to share access to a video of the conversation @angeladuckw & I hosted live @Wharton with our brilliant friends @R_Thaler & @alexolegimas about their new book THE WINNER'S CURSE & how behavioral economics has evolved in the last 30 years.

Heads up to all our Bay Area friends! ⁦@alexolegimas⁩ and I am having a conversation with some guy called Michael Lewis who can make anyone seem interesting! Come see if we can screw this up.

Alex Chan shares an updated take on how much opt-out organ donation matters. Does switching to this policy actually increase organs donated? Only in countries where consent is interpreted strictly (without requiring the additional consent of next of kin). @PennCHIBE

Great talk from @sdellavi at @PennCHIBE conference about forecasts of social science experiments’ effects. We expect effects that are roughly 2x as big as we get.

Just fyi that our registration link went down for a couple of hours, but it’s working again and we’d love it if you joined us! Apologies for the hassle!
