Having an intuitive eye for what's aerodynamic does not mean one is able to explain the physical mechanism behind it.

Explanations aside, the phenomena I mentioned go directly against common intuitions. Those intuitions are not as accurate as people think they are.

That aerodynamics is counterintuitive is fairly well accepted among fluid dynamicists. Watch this classic series of videos from MIT:

I have not watched the videos, but I did read the associated book, and it goes into detail about the counterintuitiveness.
