Well, since you asked... *cough*. I've gotten scores indicating around 170-ish. It's hard to pin down precisely because "regular" IQ tests aren't designed to accurately measure that far up and thus even with all questions answered correctly the results "cap out" lower than that. I've taken a few that were designed to cover a higher range, and gotten scores varying from 166 to 175.
And at times I can relate to the problem mentioned in the article about tending to get distracted by "too many options" (either of action, or possibilities). If you can come up with too many "what ifs" it can bog you down trying to take them all into consideration. But it's hardly inevitable, and it's just as possible to see when you're becoming too analytical and "not go there", if you take a moment to monitor your own "performance" and focus on the job requirements.
Like anything, though, some handle it better than others. Jimmy Carter, especially, was a big failure at "cutting to the chase". I forget who it was, but one of Carter's advisors once said that "some people have trouble seeing the forest for the trees -- Jimmy gets sidetracked by the leaves."
But the bright side is that the same active mind that got you into a mire of "what ifs" can also sometimes get you out quickly with an "aha!" solution that might short-circuit the potential problems.
Another common problem with a high IQ (or advanced education) is that it's easier to get overconfident and convince yourself you're capable of more than you really are. First, a high IQ helps in certain ways, but can also be no advantage in other aspects of life. Presuming that it does has gotten a lot of people in trouble (just like those who similarly mistake their money, good looks, or fame for some sort of natural all-encompassing superiority -- Hollywood, anyone?)
It's also too easy to mistake competence in one field for competence in other fields. Too many scientists, doctors, lawyers, etc. can fall prey to con-men and hucksters of various sorts (including ideological ones like Marx and his followers) by thinking that expertise in, say, brain surgery prevents them from being idiots in other fields. A related issue is the number of successful people who become amateur pilots of their own small planes, and then proceed to get themselves killed by overestimating their ability to fly competently as easily as they succeeded at some other endeavor for which they were better suited or prepared. JFK Jr's fatal plane crash seems a good example of this. To quote from a Clint Eastwood movie, "a man's got to know his limitations".
I can max the Hi-Q! (you know, golf-tees-on-the-triangle?)
