Actually, just to be picky, I think 'smart' is indeed acquired. Look at common terms like 'street smarts' vs 'book smarts'. These refer to wisdom which has developed out of a particular sort of experience.

Psychological tests measure 'intelligence'. That is what refers to certain latent cognitive abilities, whether they are well-developed or not (and ignoring the argument that many tests are culture-biased).

So Bibi's high IQ is an indicator mostly of native ability, though some development and application is required to be able to respond to a test.

What I find interesting is that usually this raw talent makes one into a thinker in a field's ivory tower. The business smarts to work with (or work over) people is another capacity, otherwise he couldn't have worked his way in the political arena.

Where did they get their info from? I've been googling this and I can't figure out how they decide who to put on the list and how smart they are.
