How many geniuses are there in the world?

There's all types of geniuses, just as there are all types
of intelligences and trades.  A MENSA genius may be a genius at taking a test that tests
for geniuses (there's bias in them), but he may not have that intelligence translate
into a successful or note-worthy speciality or a job.  In Malcolm Gladwell's
Outliers, he cites a study of so-called early childhood geniuses in
which the researcher discovered that only about half of them were even moderately
successful in the adult world.

There's 9 different
intelligences: bodily-kinesthetic, naturalist, musical, existential,
mathematical-logical, interpersonal, intrapersonal, linguistic, and
spatial.

Einstein, for example, was probably a genius in
spatial and mathematical-logical but certainly not in bodily-kinesthetic or
interpersonal.

Michael Jordan was a bodily-kinesthetic
genius, but not any of the others.  The same can be said for Mozart (musical), Faulkner
(linguistic), and Kierkegaard (existential).

Who's a
naturalist genius?  Survivorman?
