It has always seemed to me a particular duty of the psychologist from time to time to leave his laboratory and with his little contribution to serve the outside interests of the community. Our practical life is filled with psychological problems which have to be solved somehow, and if everything is left to commonsense and to unscientific fancies about the mind, confusion must result, and the psychologist who stands aloof will be to blame.

This book corresponds to a German book, which I published a few months ago, under the title Psychologie und Wirlschaftsleben: Ein Beitrag zur angewandten Experimental-Psychologie (Leipzig: J.A. Barth). It is not a translation, as some parts of the German volume have been abbreviated or entirely omitted and other parts have been enlarged and supplemented. Yet the essential substance of the two books is identical.

Hugo Munsterberg (June 1, 1863 - December 16, 1916) was a German-American psychologist. He was one of the pioneers in applied psychology, extending his research and theories to Industrial/Organizational (I/O), legal, medical, clinical, educational and business settings. Munsterberg encountered immense turmoil with the outbreak of the First World War. Torn between his loyalty to America and his homeland, he often defended Germany's actions, attracting highly contrasting reactions.
