This is the latest and most comprehensive of the series of studies promoted or patronized by Mr. Hoover, which began in 1921 with the report on “Waste in Industry.” In September, 1929, the President called upon a group of leading social scientists to examine recent social trends with a view to preparing such a report “as might supply a basis for the formulation of large national policies looking to the next phase in the nation's development.” This was an ambitious undertaking, more ambitious than any of those which had preceded it. But the President believed firmly in the method of fact-finding by commission, as was demonstrated by the contemporaneous creation of the Wickersham Commission. This belief appeared to be justified by the accomplishments of previous commissions, especially the commission whose report on “Recent Economic Changes” was then approaching completion. Be that as it may, it was logical that the series of studies should culminate with a broader view of the great society which constitutes the American community. For the purpose of making this survey, President Hoover secured the services of six expert investigators whose past performances had gained for them the confidence of American students of the social sciences. Among them there was a thoroughly competent representative of political science. There was also assurance of adequate financial support. Thus the enterprise began with a good prospect of achieving whatever it might be practicable to achieve in the existing state of the social sciences.
