"How dreadful!" cried Lord Henry. "I can stand brute force, but brute reason is quite unbearable. There is something unfair about its use. It is hitting below the intellect." ~ Oscar Wilde - The picture of Dorian Gray
I'd say that's a Nature v. Nuture question, one which is highly debatable, on both sides.
It'd probably affect the strength of a preference, maybe, since humans are very malleable, but, aside from severe mental trauma or whatever, the preferences shouldn't change totally unless one's inclinations were neither here nor there to begin with.
It's obvious types don't have the same percentages in different areas of the world. I think both culture and genes affect one's type.
Eastern Asians are definitely the most introverted (probably also Ts), regardless of where they are living -I remember I was in Canada some years ago, looking for a 'network', to play computer games, then when I found one I was shocked everyone there was Asian, while I have practically noticed no Asians on the streets- Mediterraneans would probably be the most extroverted - Extroverted feelers mostly methinks.
I'm new to this and I'm still basing it on observation, correct my flaws if they're too obvious.
genetics do obviously affect type... dont get me wrong, but that doesn't meant that it still cant be equally distributed. if you wanna look into how neuro-science is connected to personality type read The Edge Effect by Dr. Eric Braverman... its excellent and if your really interested its worth buying.

We do? Can you explain how SPs all value tradition and classical structures, please?
I can't give a direct argument based on proof here, that opinion of mine is based completely of my personal experience. It's just that from all of the people that I know of the S's are far more likely to have a view of "if it works, don't fix it." While the N's are the types I usually see that try to "Fix what's not broken".
