Ha, I was thinking about start a post about Types and Countries, and there's already a full book about it!
But what exactly it describes: the country itself, the stereotypic person from each one...?
Can you give a few examples of countries?
Ezra: UK is a good guess: I can see a pretty strong "Te" within the british type.
I don't have many guesses about Brazil's type, ecxept that it probably will be far diferent from mine.
As for that book, I still haven't read it but I do believe it's more of a "the traits of which MBTI type are most culturally valued by each particular country?" and not "which type is statistically most common in each country?".
