ABSTRACT
A fter the shock and awe of the greatest conflict in history-the killing and maiming of millions of human beings in the second world war-psychologists found it impossible to return to the academic life they had left a few years earlier. That world was gone forever. In the United States, at least, casualties were relatively low. With the nightmare of the Great Depression fading and the perception of the righteousness of Allied military might, psychologists shared in the buoyant mood. However, the specter of atomic warfare hung over all. Now psychologists, along with scientists and citizens everywhere, were caught up in the challenges of a new era of global insecurity.
