The decline in American productivity growth is documented and suggestions for action by industrial and organizational psychologists to quell this decline are made. Need for the following are emphasized: a more useful definition of productivity, more use of macrostatistics, accurate definition of problems, design of both research and carefully evaluated action programs, and actions to establish the legitimacy of industrial and organizational psychologists for solving productivity problems. To fulfill these needs, greater cooperation within the discipline and with persons of other disciplines is needed.
