You could argue -- probably with varying degrees of success, but still -- that the puzzle question is an attempt at an IQ question. Certainly, there are vaguely similar questions of reasoning ability, numeracy, and pattern recognition on actual IQ tests. Anyone who's taken one of the commonly accepted IQ tests will recall that it's full of sequential pattern matching, word-unscrambling, and so forth. And I realize that most here have probably not taken the LSAT for law school, but that test is essentially a string of interview-style brainteasers. (The LSAT was initially derived from IQ tests, though it should be said that this topic is not without considerable historical controversy).
