I have just taken the Harvard Implicit Association Test on nationalism from the UK specific pages; "The results revealed by this test provide a new method of appraising nationalism."
"Your data suggest a strong automatic preference for United States relative to United Kingdom"
Which surprised me - I thought I would be neutral (The test works by flashing words and picures which you allocate to good or bad or US or UK. However I think I was influenced by the use of Tony's grinning mug which as an Englishman I should be associating with the UK and Good but my finger hesitated every time..)
Go on take the test - it is more interesting than the "which Lord of the Rings special effect" are you ones that most Blogs do.
There is also a Race one which "indicates that most people have an automatic preference for white over black." My results are staying sealed..
