\"The trouble with the world is that the stupid are cocksure and the intelligent are full of doubt.\" – Bertrand Russell
Ignorance breeds overconfidence, while intelligence often comes with self-doubt. The more people know, the more they realize how much is unknown. Critical thinkers question themselves, while the uninformed speak with misplaced certainty. Society often mistakes loudness for wisdom, though true wisdom comes with humility. A wise person understands the limits of their knowledge.
