How'd they figure that? (logic puzzle)

Sorry, I thought I was in the spirit. Wording is important in logic puzzles, but we can also have a little fun.

I've enjoyed your puzzle and the discussion. Have a nice holiday!

Thanks - enjoy your holiday as well. That's the best spirit to be in!

I think this puzzle is plenty challenging enough without injecting additional complications. People tend to ask questions like, "well, what if not all the citizens have the same IQ - they can't all reach the same conclusions!" True enough, if the point were to be discussing a real-world problem, but I'd almost rather just reduce this to a problem in pure logic or information theory - not that I'm really sure how to do that!
