How can one prove that the selected answer is indeed the correct one? Isn't it possible that there are more concise explanations than the recognized "correct" answer that the author of the test didn't see (and indeed, couldn't have seen, since patterns are a huge powerset ...)

If the reply is that, well, it's the simplest elegant explanation .. isn't that an appeal to popular notion and not pattern recognition as a whole?

Is there any literature on the psychology of IQ tests?
