A genuine problem is that intellectual hubris is often rewarded. There are many "experts" in their field for a reason - not necessarily because they always know so much - but because we have a human bias to defer to authority figures. This bias is not going away. If you want to be able to market yourself and access opportunities that other people can't, you often have to project confidence - even overconfidence - in your beliefs. Non-experts can't tell, but they can certainly identify a lack of confidence. People have a bias for simple, clear prognostications, even if they are wrong. This is an unfortunate reality, but it is a reality. Otherwise, we wouldn't see so many charlatans passing off as experts. But we do. I think it's useful then to be able to project confidence and even overconfidence in your beliefs. But at the core, you must remain intellectually humble if you want to learn. You can't block out knew ideas because of your ego. I've summarized this philosophy elsewhere as: look high-status, but be low-status.
