Both of you are looking at it too superficially.

Kitamura is a smart person, he is depicted as being organised and hard working, he can plan and get things done.

Kitamura is also dumb, he is dumb to people's feelings and especially his own, like many teenagers are.

Both sides are part of Kitamura, it's a typical character archtype too - the high IQ person with low EQ, the imperfect perfect person so to speak (and ToraDora is all about these types of conflicting personalities), you can't have one but not the other because that breaks the character archtype.
