With all the emphasis on confidence in modern culture, its dishonest to say you should in general admit you don't understand something. In a negotiation for example, if you admit you dont understand something, the other party can use that factor to take advantage of you. It also hurts your credibility in front of a wider audience when giving a speech for example. While I do think being humble should be respected, modern culture will look down on those who admit they don't understand.
