Maybe your personality is more compatible with those in the other countries you have lived in. It's no suprise that people in different countries are different. That said, I find your characterisation to be hand waving and generalizing. Individuals are not synonym with the collective, and individuals are widely different in Norway like everywhere else.

I live in another country, and every day I have to deal with cultural differences. My choices generally are to assimilate or to feel left out. There is evidently some code you have not yet cracked, not knowing you it is impossible to tell which one.
