I think this is one of the problems with how we analyze these things. We always want to focus on the very top and point out that those that lead us aren't the brightest of the bunch, but are oozing social skills. Yes at the very top, social skills, being alpha, being able to persuade and lead, etc, are much more critical than a high IQ. But for the rest of us in between, IQ likely does correlate at least somewhat to enhanced life outcomes.
