From the wikipedia article, http://en.wikipedia.org/wiki/Iq http://en.wikipedia.org/wiki/Iq, the "positive correlations" section you can expect IQ to be useful predicting the following: • SAT score. • Job performance of a new hire when the new hire does not have existing experience. • Income, but being at the extreme high end doesn't help much more than just being high. • Health. (Some diseases are negatively correlated.) • Committing violent crimes. (negative correlation.) Genius is not in the list. I would suggest that it is something else entirely.
