America contains multitudes; by living in the right place and exposing yourself to the right information, you don't really have to be aware of all the people who determined its World Values Survey results. (I suspect this is also true in Brazil...)

Expanding on this: When comparing different countries, it can be useful to imagine "normalizing" large countries by breaking them into chunks the size of Norway. Many aspects of day-to-day experience depend only on local conditions.

Yes, certainly. But it is still the case World Values Survey results are relevant. I do not know exactly the people I will come about when I move to another country. All of them are expected to be biased towards academic values. Still, the values of the survey predict each country specific bias. I have met academics from USA on my area, and they are all very clearly much more obsessed with their careers (survival and traditional value) than with having a meaningful life. But I reckon my sample is very small.

(I suspect this is also true in Brazil...)

No. Brazil is so screw up that during 26 years I have found only one intelligent person with my set of values. Meet diegocaleiro. He is also leaving the country, by the way. In fact, most really smart people are. Note I live in Brazil's largest metropolitan area (and world's 7th), and I have visited 20 out of 27 states.

Why? You haven't expressed that living somewhere with high population density or lots of popular nearby attractions is important to you.

No, I haven't. I will address the "isolated country" factor on my reply to Kaj and then add that to the post afterwards.

Finally, note that you could remove "rationally" from the title and exactly the same meaning would be conveyed, since we're on a blog about rationality.

Fixed.
