High enough to be a hell of a fine argument against the validity of IQ tests.
EDIT: Also, Nomad, I don't have a Z table handy, but an IQ of 160 (four standard deviations above the mean) isn't THAT rare, is it? I ask because when I was four I took the Stanford-Binet test and scored 190. The mean of that test is 100 (as with all IQ tests) and the standard deviation is 16. So z=~5.63 for my score on that test. IIRC, that Z score translates to ~1/2,000,000 of a population.
Which in turn leads back to my original comment. I'm more intelligent than all but about 3,000 people in the entire world? I don't think so! I wasn't even the smartest kid in my kindergarten class (that would be my friend Elinor, whose tested IQ was 50 points below mine!) Either I'm an astoundingly gifted idiot savant who happens to have the perfect skill set for the Stanford-Binet IQ test or something is seriously wrong with that scale past the second standard deviation or so.
If you really took a valid IQ test, then the psychologist that tested you seriously needs to lose his license. Because that result is, again, impossible to get. That would seriously be gross malpractise.
Note that SD 16 will inflate the numbers more than SD 15, but not as grossly as SD 24 will.
IQ 190 SD 16 will mean you're one in 100 million.
Here's a nice chart [http://www.iqcomparisonsite.com/IQtable.aspx].
Edit: As for IQ 160 Wechsler, it's not nearly as rare. But still pretty damn rare. Rare enough that creating a properly standardized test that measures that highly would need a control group of several hundred thousand people, which would cost a fortune. You can get a rough idea on that level by taking a so-called "High range"-IQ test. But those are not properly standardized, for obvious reasons. The thing that makes them semi-valid is that they're designed by professionals who can make educated approximations. You still have to remain very careful with trusting the results of a high range IQ test, though. Like someone said a few posts above here, IQ tests start losing their accuracy after ~135 Wechsler, and they become very unreliable past ~145.

Varied between 115 and 130. Irrelevant as IQ tests are meaningless. I've seen high IQ scores on plenty of worthless people, and they only test one kind of "intelligence" ignoring the others.
I doubt you've taken multiple standardized, supervised IQ tests. You've taken internet tests. Those are, again, not accurate.

You should read some psychology papers on intelligence. For infotainment wiki always helps

I suppose cetaris paribus its better to have a high IQ score, but I'm disputing whether it has any real meaning. The most common criticism is that it only proves that you're good at IQ tests. Which I am. Everybody says I'm "smart", but meaningful empirical measurement of this quality is very difficult to accomplish.
That is... seriously a pet peeve of mine. What Gardner did there was simply sloppy. He should've a term like "gifts" or "talents". He took the term "intelligence", which meant one thing, and attempted to transform the meaning into something else. Sort of what happened to "gay". It originally meant happy, but then someone thought it would be nice to go and change the meaning.
Saying you're musically intelligent is like saying you're visually verbal or bodily mathematical.
Intelligence is a subgroup of
talent, not the other way around.
I agree that what you mention is the most common criticism, among laymen, towards IQ tests. But I also have to mention that there has been absolutely no valid argumentation to support that thesis. It just seems to be a "politically correct" thing to believe. I honestly don't know where this irrational disdain towards the concept of IQ comes from - my suspicion is that it's based on the tall poppy syndrome.

I've gotten scores ranging from 120 to 148 before. There's no standardized IQ test, so using an Intelligence Quotient to measure your intelligence is just kind of useless. Each test has a different difficulty, and so the answers will always be skewed.
That is simply not correct. There are multiple standardized IQ tests - it's just that none of them are to be found at the internet. Off the top of my head, I can mention WAIS, RAPM and FRT as properly standardized and accurate IQ tests. You can take the latter through your national Mensa branch if you're interested. But yes - unless you specify what test you took, and what scale it used, the number says little.
The difficulty of the tests are irrelevant. Because it's not a matter of how many questions you get right, the score is weighted according to the distribution of the test populace. If only 2% managed to get 3/40 correct answers on the test, then 3/40 correct answers will represent an IQ of 131 Wechsler. If 50% get 40/40 correct answers, then it's a low range IQ test and only measures up to the maximum of 100 Wechsler. The actual raw score is irrelevant - the weighted score is what matters.
