According to a recent study by the psychologists at the Friedrich Schiller University in Jena, Germany, “Accent is much more important than the way a person looks”.
An accent is a way to classify people quickly and to make sense of the world. This is good in some respects, but may lead to people being classified by perceived negative traits from a class or ethnic group.
Learning an accent to use in work or social situations then, may lead others to perceive you the way that you prefer.
