I think the blind faith is less about whether they can guess what's needed and more about always portraying confidence and saying that you'll succeed. How seriously are you going to take a product when the CEO of it sounds hesitant or sounds like he's hedging his bets? If you know a lot about the field then the honesty might be refreshing, but if you don't know much about the field then it won't seem appealing.
