I had hand surgery yesterday. For anyone looking for a voice-to-text app, I cannot recommend @WisprFlow enough. A big thanks to Ben Olken for the recommendation. And yes this was written with WisprFlow.

A few years ago Mike Luca and I talked about writing a book called Businesses Behaving Badly about how companies exploit human frailties in judgment for profit. If we did it now, this would be the opening story: nytimes.com/2026/09/19/busin…

A student today told me that they read a Dan Ariely book in AP: Micro, and asked if she should forget everything she read in it, even though it sounded so true.

Wow. The effect sizes had always seemed...surprising. Kudos to Wertenbroch for sharing the data.

I am sure others have done this breakdown, but if you want to experience how fast Sebastian Sawe ran the London Marathon, go to a track and try to run 400m in 68 seconds. If you are in truly amazing shape, maybe you can do a second one. Now imagine doing 103 more.
