We are now planning further research in national characteristics. In a recent seminar at Yale University students were given the task of trying to identify behavioral characteristics that might help to illuminate the Nazi epoch in German history. The principal suggestions were that Germans might be found to be more aggressive than Americans, to submit more readily to authority and to display greater discipline. Whether these assumptions will hold up under experimental inquiry is an open question. A team of German and American investigators is planning a series of experiments designed to provide a comparative measure of behavior in the two countries.
