If measured by IQ that's believed to be Kim Ung-yong at 210. Still. if he would not have had poor academia experiences (what did he do at liberal arts college anyway?), he might have been very useful to the world. Terrible waste.
His chance of doing anything is the same as everybody else.
We we can do is to put general parameters around it, such as "beautiful people tend to be taller." In the same way, scoring generally well (over 120 or 130) on an IQ test is like saying you're tall. It's actually meaningless as to how smart you are, but they share some of the same parameters, so they will correlate a bit more.
