I'm white and got 7/18 and it said "You can't tell the difference" but I think it's because some of them I had no idea. There were a few where I was really sure and I turned out to be right.

I think it's the same with white people. There are some who look unique to their country and I can tell with high confidence but for others, I have no idea; they just look like a generic white person.

For example, I think these public figures look/looked very stereotypical for their country:

German: Otto Von Bismarck

English/Scottish: Hugh Grant, David Bowie, Winston Churchill, Maggie Smith

French: Napoleon, Jacque Chirac, Alain Delon, Gerard Depardieu, Francoise Hardy

American: Clint Eastwood, Abraham Lincoln, JFK

Swedish: Agnetha Faltskog
