There is a peculiar social reward for sounding certain. We trust the person who answers quickly. We admire the clean opinion, the decisive take, the person who seems to have already sorted the world into neat categories.
But certainty and accuracy are not the same thing.
Psychologists use the term intellectual humility for something more useful than self-doubt: the ability to recognize that your beliefs may be incomplete, limited, or wrong. That does not mean having no convictions. It means having reasons for what you believe while leaving the door unlocked for better reasons.
One useful question is: what would change my mind? If the answer is nothing, you may not be defending an evidence-based belief at all. You may be protecting an identity, a loyalty, or a story you prefer.
The goal of a conversation does not have to be victory. You can leave with a more precise version of your own position, discover that the other side was right about one part and wrong about another, or simply say, “I hadn’t considered that.”
Maybe the strongest opinion is not the one that never moves. Maybe it is the one strong enough to survive revision.
