That's not the problem, that's the stroing point. Mathematical notation is created (rarely designed) to express some concept consisely and in a way that helps *the person creating it* thinking about the concept/using it correctly. Anyone doing non-trivial math develops new notations all the time. If lots of other people find a particular notation helpful it sticks. It's a natural selection following the devlopment of the field.
The last thing we need is notation designed by cognitive psychologists who don't even understand the mathematical concepts. As for graphical design, notations are typically first created for writing by hand (scribbling, actually). The time for typographical refinement comes when (if) they do stick.
