What is self reference criterion in international marketing?

The SRC (Self Reference Criterion)  is an unconscious reference to one’s own cultural values, experiences, and knowledge as a basis for decisions. Closely connected is ethnocentrism, that is, the notion that people in one’s own company, culture, or country know best how to do things. Ethnocentrism was particularly a problem for American managers at the beginning of the 21st century because of America’s dominance in the world economy during the late 1990s. Ethnocentrism is generally a problem when managers from affluent countries work with managers and markets in less affluent countries. Both the SRC and ethnocentrism impede the ability to assess a foreign market in its true light.

Say for Example, consider misunderstandings that can occur about personal space between people of different cultures. In the United States, unrelated individuals keep a certain physical distance between themselves and others when talking or in groups. We do not consciously think about that distance; we just know what feels right without thinking. When someone is too close or too far away, we feel uncomfortable and either move farther away or get closer to correct the distance. In doing so, we are relying on our SRC.
