Factually, I.Q. does not translate to: "You are n points smarter than this other person, who scored n points lower than you."
Rather, it should translate to: "Your I.Q. as measured by this test is x, putting you at the kth percentile, meaning you outscored k percent of the population who took the same test as you did."
Since I.Q. is measured on a bell curve, the difference of even 1 point could mean the difference in rarity of a few thousand or even more at higher ranges. Also, I.Q. is the single best predictor of success so it most definitely is not futile. http://www.paulcooij.../int_jonah.html <-- Last paragraph on this page addresses the issue of multiple intelligences.
It just so happens that I.Q. measures selective perceptual ability and logical and rational thinking, which is basically what intelligence is. It's the ability to make sense of things and then to maximize the utility of the outcome as pertains to one's goals, using the information obtained in the first place.

Intelligence is born out of thought integrity and courage springs forth from love. Bush is the most corrupt person I have ever seen and he has zero courage.
How is it absurd? Conversions from SAT scores are as reliable for Bush as they are for everyone else. If it's absurd, then the problem is with the conversion table and not with the notion itself. An I.Q. of 90 would mean that Bush couldn't have gotten the SAT score that he did. Further, there is no relevant evidence to prove that his I.Q. is NOT 120+ so at best the notion of Bush's I.Q. being 120+ can be questioned on grounds of lack of conclusive evidence for it, and not because it's "absurd". Regarding "smart", it's entirely possible that his ideals and therefore goals were entirely different from those of the people who don't agree with his actions. In general, an objectively "smart" person is capable of achieving his goals. A kind of "smart" like planning for the greater good etc is only subjective, in the sense that planning for the greater good can be argued for or against with equal validity.

This is true for most comprehensive I.Q. scores. However, on "power tests" (untimed, unsupervised tests of extreme difficulty) like Ronald K. Hoeflin's now famous "Mega Test", the required verbal knowledge is not what is difficult, or anyone would be able to solve the verbal section using a dictionary or thesaurus. What is difficult about the verbal sections on these tests is the obscurity of conceptual constitutes involved in the analogies. This makes these verbal items more alike to the spatial items in that you're looking for a "rule" that best describes the connection(s). Otherwise, Cybele is correct in stating that many questions on most comprehensive I.Q. tests have lots to do with education and "smart" can be a really broad and misleading term.

"Fitness tests only measure how good you are at fitness tests. They don't measure how fit you are." Does that make sense at all? It's called a fitness test for a reason. It contains the specific test items for a reason. I don't claim that I.Q. tests are valid for the same reason that fitness tests are valid. However, there is a reason people with extremely low I.Q. do not ever achieve anything requiring extreme intelligence. There is also a reason why people with extremely high I.Q. learn things easily and often are able to reason, abstract, and invent on a level far beyond the comprehension of someone with significantly lower I.Q. and you will never see a reversal of these roles.

I agree with everything up till the last sentence, on which I'm actually undecided. There is evidence for both sides of that argument and since I'm neither a statistician nor a psychometrician by training, I can't say anything except maybe that I favor the single measurement of "g" more than multiple intelligences. It seems multiple intelligences complicates the issue and violates the principle of Occam's Razor. Nonetheless, here's a link that talks, in brief, about the theory of multiple intelligences.

I take it you know these people well enough to know that first, they're not lying about their I.Q. and second, the reported I.Q. is preferably a deviation I.Q. on a 15 or 16 point scale and third, that dumb refers to said people being unable to achieve goals even if they tried. Otherwise, your personal experience is no better an indicator of the invalidity of these tests than another's personal experience that claims otherwise.

The questions on the show are culturally loaded and also, many of the questions are definition based, which means strictly speaking, it does not matter how smart you are if you don't know the definition. If for example you didn't know what a octagon is then you cannot possibly answer how many sides it has. Of course, in reality it's more complicated because you could guess the answer with knowledge of the prefixes and/or suffixes though it would be in the TV producer's best interest to include only questions that cannot be figured out that way.

Think of cryptic crossword clues... they may baffle you (they do me) but once you get a feel for the angle the writer is taking, they become easier to solve; you don't learn anything from cryptic clues though.

Mensa uses culturally loaded I.Q. tests exclusively (Source: http://www.prometheu.../multiple.html), and if I am not mistaken, Mensa tests are timed. Of course improvement would be possible, and on 3 levels at that. First way to improve is to practise these tests so that the style becomes familiar. Second way is to assimilate the culture such that the content becomes familiar. Third way is to save time on the actual test using method 1 and 2 such that one has more time to figure out the remaining items of higher initial difficulty. The statement about the rocket scientist is a moot point. First of all, rocket science requires vast prior knowledge, which is the opposite of what I.Q. is supposed to measure. Second, you are supposing that the Mensa test will not make someone understand technical information a rocket scientist understands and by corollary, will not make that person qualify as a rocket scientist. Of course not, but is that supposed to be a surprise? The Mensa test is not intended for such a purpose in the first place. There's not the slightest sign of a causal relationship between the Mensa test and becoming a rocket scientist.

As an example I think everyone would agree that Mozart was genius for his music, yet his IQ score was probably horrible.
Definition is definitely key. However, the question of whether Mozart was a genius has been addressed (and the conclusion was no, he was not a genius, just very intelligent but still a product of about 10 years of hard work) and his I.Q. was probably NOT horrible. Although in Daniel J. Levitin's book, "Your Brain on Music", he claims that approximately 10 years worth of practice is necessary to achieve mastery, I doubt that just any child could have endured the practice that Mozart did. It would've taken a keen intellect to be able to master his craft the way Mozart did. We have plenty of child prodigies these days in music, yet not many are comparable to Mozart. Regarding Mozart's I.Q., here is a link: http://www.iqcompari...com/Cox300.aspx
This study has been criticized before so I'm not sure how valid it is. However, it's definitely believable that Mozart did not have a low I.Q. considering he was a master of composition by classical music standards, where the complexity surely would have overwhelmed a weak intellect.
1st edit - replaced 99.99 with "k" when addressing percentile
