I think most ppl have weak attention spans and can't get into flow state while listening to stuff. It's definitely a muscle. If they can listen to it and take what they say as truth, maybe.
I've spoken to many "smart" ppl about the podcast and they can't get past the first episode. But the ppl that can, do get their mind blown regardless of prior Bitcoin knowledge. Starting from the beginning of human energy channeling really sets the stage.
I also think most bitcoiners are life long learners and autodidacts. These two things combined with a high degree of open mindedness might be what set the cohort apart.
