Performance involves achieving goals, which obviously takes intelligence. However, I believe that as your intelligence grows you stop seeing what you are doing in a narrow fashion and tend to think more in terms of systems and many goals that are interrelated. When that happens, you will not optimize for one goal but for many. Someone with less intelligence may outperform you on a measure of one specific goal, but you will outperform overall (overall meaning not at your job, but at your life). So performance has its limitations as a measurement for intelligence.

This only works for those somewhat close to the mean. People who would be many standard deviations above the mean may be so intelligent that their intelligence would be mistaken for foolishness or others may not be well equipped to measure it.
