This is Volume III of seven in a collection on Social Psychology. Originally published in 1932, the study upon which this volume is based was conducted under the auspices of The Inquiry, an organization devoted to the analysis and improvement of conference methods. The project began as a fact-finding investigation directed toward newer phases of industrial management, particularly managerial instruments in which both employees and employers participated. (Such instruments are usually called ' employee representation ' or ' company unions.') So the study developed in the direction of exploration with newer research techniques and it finally became a project in research method rather than a conventional fact-finding inquiry.
