Funny, the first thing most notice is the sex of the other person and their attractiveness. If positive it biases the rest.
Interestingly, experience has shown me that smart people take that into account.
With experience, smart people can take that into account and set it aside.
They they evaluate the warmth and competence. However, good looking people of the right sex in a situation have an advantage, if they can match warmth and competence because they can not only get the people who might value warmth and competence, but they can also corral the people who are more easily manipulated by sex and good looks.
