Christensen's study was called "Why Danes Are Smug," and essentially his answer was it's because they're so glum and get happy when things turn out not quite as badly as they expected. "And I was thinking about, What if it was opposite? That Denmark made the worst, number 20, and another country was number one. I'm pretty sure the Danish television would have said, 'Well, number 20's not too bad. You know it's still in the top 25, that's not so bad,'" he says.
