Because you're wrong. The highest frame rate the human brain can register is much greater than 12 fps.

 

maybe i worded it wrong, but things look smooth at 12fps so why do we need anything higher?

What looks smooth at 12 Fps I had Doom 3 instilled when I had a virus and I knew amedenatly I was infected be of the slow speed. 12fps is unplayable in most cases.
