I just listened to the episode on the sunk cost fallacy, and really liked the audio/recording quality, and the stories and examples of how others can be irrational. Since you asked for feedback, though, one thing I noticed was that between 3:45-4:30, the moral of the stories was presented from a framing of "if you did X, you would have been wrong/irrational". This framing is probably not too aversive to most rationalists, but might be a bit more uncomfortable for more socially sensitive individuals to listen to.

Good job on the podcast overall. I gave you 5 stars :)
