The issue with all this is that, professionally, we're held by businesses and clients to basically know everything (then there's the legal liabilities I won't touch on). So the culture is, any admission of ignorance or clear signs of knowledge gaps labels you culturally as being incompetent in your field or profession. So this problem stems well beyond school. In school you get a pass of being ignorant. Once you leave, people falsely assume you somehow miraculously have no knowledge gaps which just isn't remotely realistic for any human. Everyone always has knowledge gaps in some context, including their own fields and even specialities. We need to change the culture so people can admit or show signs of these gaps to improve. I do it often, if I'm sitting in a meeting somewhere and don't know something I let people know I don't know and will fill that gap or ask them to explain so I can learn. This, from my experience, has made more cohesive teams because people are then more willing to admit their own gaps and teams begin to work together more now there's a bit of a humility baseline.
