Confucius advocated that "knowing is knowing, and not knowing is not knowing", and he kept his mouth shut about things he didn't know, so people with below-average intelligence certainly couldn't know everything. Admitting what you know and what you don't know is an honest attitude and the smartest attitude, except those mysterious things.
Extended data:
A reading method advocated by Confucius. If you read blindly without thinking, you will be led by the nose and lose your mind. The so-called book is better than no book, that's what I mean. And if you dream blindly but don't study and study hard, you will only build a tower on the sand and get nothing. Learning and thinking complement each other and are indispensable. Only by combining learning with thinking can we learn practical and useful knowledge.
Kant, a western philosopher, also said that "perceptual ignorance is blind, and intellectuality is empty without sensibility." This is strikingly consistent with Confucius' "learning without thinking is useless, thinking without learning is dangerous". It can be seen that no matter how different regions and races are, the fundamental principles of human learning and acquiring knowledge are often the same.
