>Most people don't understand just how mentally unwell the US population is

The US is no exception here though. One in five people having some form of mental illness (defined in the broadest possible sense in that paper) is no more shocking than observing that one in five people have a physical illness.

With more data becoming available through interfaces like this it's just going to become more obvious and the taboos are going to go away. The mind's no more magical or less prone to disease than the body.
