"Nobody was permitted to see the Emperor of China, and the question was, What is the length of the Emperor of China’s nose? To find out, you go all over the country asking people what they think the length of the Emperor of China’s nose is, and you average it. And that would be very "accurate" because you averaged so many people. " (Quote by Richard Feynman)

Feynman was making a comment about ‘judging books by their covers’ – and all that the metaphor implies. And it is a damned good point.

To conclude my argument, another quote (this time Alexander Pope)

A little learning is a dangerous thing;

Drink deep, or taste not the Pierian spring;

For shallow draughts intoxicate the brain

And drinking largely sobers us again.
