The article provides absolutely no data to support any claims of a brain drain away from America, towards Europe or anywhere else. You’d think they would have found evidence if there was any. So after reading this, my prior on substantial numbers of researchers moving to Europe has gone down.

There is an obvious plausible reason why there might not be much brain drain to Europe: salaries are much lower there, because Europe is poorer.

Academics love to believe they don’t care about money, and Guardian readers love to believe that the US is doomed by its moral failings. I’ll believe both those things when I see evidence for them.
