The Lewis model explains every culture ( ! )

America is cool, sticks to facts, and results-oriented, while Russia is warm, emotional, and people-oriented? Those are new for me even as stereotypes. They may not explain things that happen very well.

Edit: one of the comments points out that this is basically new terms, “multi-active” and “reactive”, in place of the usual “hot-blooded” for blacks and Latinos and “submissive” for Asians - even coded red and yellow. Very much agreed.
