You know, it's funny. Those with high IQs tend to comment in IQ threads while those, ahem, with lesser IQs, tend to disappear into the shadows. Standard IQ tests, however, are naturally weighted according to one's socioeconomic level and culture. As an example, say one of the questions on the test for young folks asks what is common for a cup, a coffee cup. There are 4 possible answers and the correct answer is a 'saucer'. Cup and saucer, no brainer, right? Wrong. Suppose the child taking the test comes from a disadvantaged, read: poor, family and never had saucers. This child would not be able to correlate the two and would be marked down in intelligence. Except for the fact that this would only be a statistically anomaly, not a true indications of the individual's intelligence.
