People seem to have a lot of anecdotal examples of IQ not correlating to success. This has been the case with me, also. But then again, I haven't known a lot of objectively successful people (millionaires), but the few I do know do have high IQs.

It's not that IQ makes you successful, but it makes it a lot easier, and people who are successful tend to have high IQs.

To me there's IQ, being smart and the ultimate is the wisdom to employ the first two.

Yes. There's a reason behind the etymology of "philosophy"

"Philo" + "Sophia" = the love of wisdom.
