Or maybe she called him dumb out of spite, in the heat of the moment, and not out of an evaluation of his academic prowess? That seems like the more obvious choice than her being condescending because her siblings aren't prodigies.

As for needing to see hear what a character says in order to believe it's true...not really. But the thing is, there's a difference between "seeing things for what they are" and imbuing your own fabricated depth into crevices of the show that the producers have yet to fill for themselves. Actions may speak louder than words but much like words, actions can be misinterpreted until truth and objectivity takes its course and discerns fact from fiction.
