A new Harvard business school study confirms that if an individual is clearly of a particular quality, they don't need to worry about proving it.

Reminds me of the anthropologists who told me a story about class in Britain...'I saw a man weeding his front garden, and noticed he had several garden gnomes. "Wow", I thought, "I didn't know working class people still lived on this street", I smiled at the man and said hi and he said "morning" back. Duh! How silly of me. Of course - he was upper class and the gnomes were ironic. How did I know this? Simple. A middle class person would never own gnomes for fear of being mistaken for someone who actually liked them!'
