Dr. Dormann uses this definition when analyzing a case history. This impulse to escape danger, he claims, is a strong enough impulse to goad people toward the incestuous bed. How precisely do people react sexually when gripped by the neurosis of fear? The Encyclopedia states that, "… this reaction (fear) contrasts with anxiety, which consists of vague feelings of impending disaster, arising from indefinable threats. Fear is usually more temporary and more directly related to external events than anxiety; anxiety is likely to be more persistent and to stem primarily from internal problems involving feelings of inadequacy or guilty impulses. The two reactions are frequently found together especially in situations of pervasive danger such as combat…"

In over ninety percent of all case histories analyzed by Dr. Dormann, fear and anxiety were found together. The case subject was not only afraid of outsiders but anxious about his or her own ability to function outside of the family unit. In brief, they were afraid of rejection.

In the family, they knew they would be accepted. But functioning outside of the unit, they were anxious about their own ability to compete. An older woman was afraid her advances towards a desired young boy would be laughingly rejected. But inside the family structure, she knew she had to be accepted. If Grandmother wanted to be sexed by her grandson, she knew her desires would be respected and carried out. An older aunt could select a young nephew for her bedroom companion and she knew also that her request would be quickly and gladly honored. Conversely, an older man could voice a desire to sleep with his young niece or daughter. There would be no problem as to acceptance or rejection. But outside of the family, the older man could be ridiculed or even jailed for making such advances. The family structure provided the older members with security. They could not be harassed by the authorities for having sexual relations with minors, and they needn't fear they would be laughed at by a callous youth.
