In warm-climate cultures (which, incidentally, include the lands where biblical culture evolved), much more attention is paid to collective identity. Perhaps the most important thing a child can learn is that he/she is part of a whole -- a village, a clan, a tribe -- and because of that, the child has significance. The Maoris of New Zealand are said to have a saying, "I belong; therefore I am."
Needless to say, the implications are huge. When important decisions are to be made, the concern in the hot-climate culture will be the good of the group as a whole. A spokesperson will be careful not to speak for himself but make sure he is representing his people. A cold-climate person will not necessarily stop and think of the common good or the opinion of his group as a whole; what's important to him is that his voice be heard.
We must be clear that we are not distinguishing between right and wrong here -- those intent on a right or a wrong are missing the point-- but the distinctions are so significant that anyone seeking cultural intelligence -- whether the business person, the leisure traveler, or simply the culturally curious -- will do well to understand them.
