For a typical description the Western view of IQ, look no further than the game show "Jeopardy!". In the show, three above-average people compete in a trivia showdown to amass the most cash, and for a chance to compete again on the next show as the champion. Many Americans would be quick to call a daily winner very intelligent, but when considering the truth of IQ, they may not be smarter than the average viewer.
The main factor behind this point is that, for the most part, "Jeopardy!" is merely a game of trivia. Questions (well, answers) from it, though phrased quite variably, are similar to those that you'd find on a typical "Trivial Pursuit" card. While an IQ test such as the WAIS inventories many different aspects of intelligence, like arithmetic, puzzles and patterns, trivia shows like "Jeopardy!" deal with only one: information. Therefore, many people who score average, or even worse, on an IQ test could be successful on a trivia show, where the only necessity is general knowledge and, well, trivia. Without taking many different standards into account, we can not look at game show winners and immediately describe them as intelligent.
