Best Answer - Chosen by Asker:

Genius is that quality which allows you innately to surpass others in a particular part of the more favorable traits of humanity. Genius comes in many types (intellectual, emotional, artistic, and so on) and should never be considered IQ-based, as the IQ test is a sham anyway.

I consider most geniuses to have a quality which makes them outliers: often they possess a little quirkiness in manner or personality. It's this extra spark which makes them rise above the rest, no matter what kind of genius one happens to be.
