For centuries, race was believed to be a legit basis for the social classification of groups. Although it is scientifically proven that race does not exist in the human genome, people still choose to believe it is real. This is due to the fact that " what is defined as real its real in its consequences" according to the Thomas theorem. As stated in class, the dominant group imposes the concept of race because it benefits them. Because of this, people are negatively affected by this social concept.
