Considering how so many awards and lists and rankings are politically driven rather than based on facts or reality, I'll take this with a grain of salt. Just like the two best universities are now british nonsense according to a british run "Times Higher Education".

I'm sure there are a lot of great innovation going on in south korea and sweden, but there is no way to measure "innovation". Is US patents really a criteria for innovation ( Samsung has the most US patents after IBM according to the article ). And I'm sure the world economic forum doesn't have an agenda either.
