The usual phrasing of the law is nice and snappy, but I think one of the examples in the Wikipedia article -- "Can the middle class be saved?" -- demonstrates that the right formulation is something like this: If a headline is in the form of a question, the right answer is almost certainly whatever answer is least surprising. If you see a headline along the lines of "Did we really evolve from apes?", "Does the earth still go round the sun?", "Can humanity survive?", etc., it probably means that some crackpottish idea has come up that would make the answer "no", and that the headline writer knows that actually endorsing it would be a step too far.
