Sally Kohn: What does self confidence necessarily accomplish? In other words, maybe it just feels good, but it doesn't lead to greater accomplishment. Do we know if it does? Literally right now? She says she's in correspondence with a psychologist who disagrees with her on this point of confidence. But i think over longer frames, when the stakes are real and in many cases your egois involved, i think absolutely your confidence matters.Kohn: Maybe there are circumstances in the lab where in that little arbitrary experimental task, you were like, o gret, if i did that, well, i'm going to take my foot off the pedal a little bit the next thing.
