ABSTRACT
Industrial/organizational (I/O) psychology and organizational behavior (OB), as applied sciences, have many ties to subspecialties in psychology as well as other disciplines. Also, they have many ties to institutions and industries that have provided impetus and opportunity for them to develop. None of these ties, however, are as strong as the tie between I/O psychology and the military (Driskell & Olmstedt, 1989). In many respects the early history of I/O Psychology is simply the history of military psychology. Without support from the military, one can only speculate about whether I/O psychology would have thrived or died. There can be little doubt, though, that if I/O psychology had developed apart from the military it would be very different from what it is today.
