Passage One Psychiatric tests show that a well-balanced person gets much angrier when offended than an abnormal person does. At the New York State Psychiatric Institute, Dr. James Page and Professor of Psychology Carney Landis of Columbia University studied the reaction of 200 normal persons and 210 abnormal persons. They tested their reactions to annoying situations of every type and variety such as: being laughed at, being repeatedly disconnected on the telephone, accidentally hitting their thumb with a hammer, being worked on by a backseat driver, being told to "shut up" and mind their own business, discovering someone cheating in a friendly card game, etc. In almost every instance the anger reaction of the normal group was much more intense than that of the abnormal one. "This," they reported, "is agreeing with other psychiatric findings. For one of the outstanding symptoms of mental unbalance is lack of emotion. So if you blow your top when you hit your head against a piece of furniture, or when your girlfriend goes out with another young man--don’t worry about it. It is just a sign that you are normal."
