An interesting question has been asked - it seems that the author interviewed each of the 7 billion of the world's population ... And everyone answered him the same!
This is called "generalization" and is usually very far from a real understanding of the situation.
In particular, what meaning does the author of the question put in "smarter"? More educated, better knowledgeable, making the right conclusions, self-confident?
People often judge others by themselves. This makes some sense, since almost everyone has a head, arms, legs, and mosk. But there can be very different ideas in "Mosca"! Including about their own mental abilities ...
"People usually think that they know something, but it turns out that they do not know anything. Thus, it turns out that, knowing my ignorance, I know more than everyone else," he argued. " (c) Socrates.
This dictum has a more popular form: "the more I know, the less I know."
I think that every person, simultaneously with his development, begins to notice that he still doesn't know too much. And with each step forward, even greater expanses of the unknown open up. No great scientist or just a person with a huge level of intelligence will ever say that he is smarter than another (a seller in a store, for example), because understanding and acceptance of other personalities is born, and this stupid need for self-affirmation disappears. ("I am smarter than you" sounds like a child in kindergarten is saying to another child)
And, by the way, very rarely people put themselves in the shoes of others. Because for each of us the world exists only as we see it, well, why change something, why should I, the crown of creation, put myself in the place of someone? (It turned out funny) This is where egocentrism appears.
Well, I will not say that everyone
