The existence of blocs in the General Assembly of the United Nations and the importance of their activities have been widely recognized ever since its establishment. Special attention to the phenomenon of bloc politics dates roughly from the ascendancy of the General Assembly over the Security Council after 1950, and the consequent importance of votes in the General Assembly. Because the various blocs and groups of states play a conspicuous role in the decisions of the Assembly, the operation of these blocs is well worth study. Among the many aspects of bloc politics in the General Assembly needing careful analysis, two of the most basic questions are the identification of blocs and the measurement of their cohesiveness or bloc-like behavior. The purpose of this essay is to review and evaluate the manner in which students of the United Nations have treated these two fundamental questions, and to suggest an alternative method not handicapped by the weaknesses of the techniques so far employed. The advantages of the proposed alternative method will also be demonstrated by applying it to a specific instance of bloc voting: the alignments on the colonial issues which arose in the 1956, 1957, and 1958 sessions of the General Assembly.
