The more you learn, the more you realize how prior knowledge will affect your openness to new ideas. One way or another, we are seeking recognition to what we do, or confirmation of our long-held beliefs, or simply an explanation to the paradoxes in your life, as long as it's not your fault.
This third trip to the States reinforced my preference for all things European; I never realized how British my tastes / line of thought really were until challenged by something as fundemental as diction. It wasn't even the "preferred tone colour" that I felt most resistant to change.
It might not be a good thing, but so far, I'm not convinced.

The imagination is indeed a powerful tool, especially in masking the many pros and cons of a certain space. It might just be that the Brits are better at hypocrisy or putting up a facade. Some consider it a difference in confidence, and I tend to agree, but in the opposite manner - the more you say about something, the more words you use to justify your cause/argument/views - it doesn't necessarily mean you're more confident of your stance.
Sometimes, less is more.
