A man from the country seeks the law and wishes to gain entry to the law through an open doorway, but the doorkeeper tells the man that he cannot go through at the present time. The man asks if he can ever go through, and the doorkeeper says that it is possible "but not now" ("jetzt aber nicht"). The man waits by the door for years, bribing the doorkeeper with everything he has. The doorkeeper accepts the bribes, but tells the man that he accepts them "so that you do not think you have failed to do anything." The man does not attempt to murder or hurt the doorkeeper to gain the law, but waits at the door until he is about to die. Right before his death, he asks the doorkeeper why even though everyone seeks the law, no one else has come in all the years. The doorkeeper answers "No one else could ever be admitted here, since this gate was made only for you. I am now going to shut it."
The work on decision making enriched the literature of international relations by demonstrating the relevance of concepts from other areas of social science. However, the collection of data on variables describing a specific decisional group presents methodological difficulties of a different order from those encountered in “measuring national power.” Documentary materials may not even reveal the membership of a decision-making group, requiring the decision-making researcher to move from the library to field work in governmental agencies in his quest for data. Thus, decision-making analysis has stimulated the application of the field-research techniques of social science to the study of international relations. Problems in gaining access to foreign policy decision makers, because of the secrecy that traditionally surrounds their activity, require the international relations researcher not only to borrow field-research techniques of other social sciences but also to adapt them and to develop his own.
