If I was in India, and walked into a company meeting with a diverse set of people, I would assume the Indian looking person is the CEO. If I was in Japan, I would assume the Japanese looking person was the CEO.
This isn't racism. This is the human brain using pattern recognition to evaluate a situation and infer information as best it can under the circumstances.
