⁸ Although it has been used rather frequently in other disciplines, to my knowledge the only application in comparative or international politics is a paper by Banks, Arthur S. and Gregg, Phillip, “Grouping Political Systems: Q-Factor Analysis of A Cross-Polity Survey,” American Behavioral Scientist, 9, 3 (November, 1965), 3–6CrossRefGoogle Scholar. An application to the Kansas state legislature can be found in Grumm, John, “A Factor Analysis of Legislative Behavior,” Midwest Journal of Political Science, 7 (1963), 336–356CrossRefGoogle Scholar. It is worth noting that in his pioneer study of voting blocs in the United States Congress David Truman discusses the difficulty of finding blocs in a large matrix and suggests factor analysis as a method possibly superior to his own; The Congressional Party (New York: John Wiley and Sons, 1959), p. 329Google Scholar.

⁹ Committee votes often preview later plenary ones, but more frequently there is no plenary roll-call vote repeating one in committee. Even when the same paragraph or resolution does come up again the alignments usually shift somewhat; there are no duplicates in the following analysis.

¹¹ In Tables 1 and 2 I present the factors as rotated according to the varimax technique. Unities were inserted in the principal diagonal of the correlation matrix. “Rotating” the original factors to “simple structure” maximizes the number of both very high and very low loadings, thus making interpretation easier. Each factor has an “eigen value” which expresses the amount of variance in the entire table that it accounts for. The eigen value, when divided by the total number of variables (countries), gives the percentage of variance accounted for by the factor. All 15 factors with eigen values greater than one were rotated. Nine factors which had no more than one loading as high as .50 are omitted from the table.

¹⁴ In all there were nine factors with eigen values greater than one, accounting for 75 per cent of the total variance. I list here only those roll-calls which correlated at least .71 with the underlying factor, and thus more than half of whose variance can be accounted for by the factor. More detailed information on the resolutions can be found in the “Summary of Activities” of the General Assembly in International Organization, 18, 2 (1964), 313–467Google Scholar and of course in the Official Records themselves. International Conciliation, No. 544 (September 1963) discusses the issues before their consideration by the Assembly.

¹⁸ The fact that the Afro-Asians correlate more highly than do the Communists with the “cold war” factor indicates that the latter is a slightly misleading label. There are some roll-call votes, such as those about the role of the UN in reunifying and rehabilitating Korea, or establishing a fact-finding commission for the peaceful settlement of disputes, which have substantial “supra-national” loadings and overtones. On these votes the Afro-Asians and Communists often part company, at least to the degree of an abstention. Putting a descriptive label on a factor is always a somewhat tentative exercise, which is why I have here enclosed the labels in quotation marks.
