Evidence: By the end of the nineteenth century, industrial, or personnel psychology, was developed as a way to understand work behavior. One influential figure in the beginning of this new area was Hugo Munsterberg, a German psychologist who was trained by Wilhelm Wundt and who also worked with William James. As opposed to war defining most of the twentieth century and the use of the applied psychology, economics will be the main focus of the twenty-first century.
