This polling reminds me of an observation by a politician that you really cannot trust the public as the public vastly overestimate their understanding of things.

As somebody who loves using Roman numerals I find this polling but hilarious and sad at the same time. I think there is a clear correlation with people perceiving understanding Roman numerals as a sign of strong intellect so think they are cleverer than they actually are.

I think LXXXII per cent of people will think they get the subtle joke in the headline whereas the reality is maybe only XLIV will actually understand the joke.
