Administration is both social engineering and applied psychology. It is apparatus and mechanics, incentives and human nature. Let no one think it is merely the former. Nowhere is the need for psychology greater than in the organization, direction, and inspiration of men working in large groups. Outstanding administrative results are produced by spirit, morale, atmosphere; these, in turn, are the product of psychological mainsprings and invigorating incentives. As Benjamin Lippincott has recognized, both governmental and business administration resolve fundamentally into the role played by effective incentives.
