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?
