THE DIMENSIONALITY PARADOX IN COMPARATIVE JUDGMENT: A RESOLUTION

S jöberg , L. The dimensionality paradox in comparative judgment: a resolution. Scand. J. Psychol ., 1968, 9, 97–108. — It has often been possible to erect unidimensional scales although stimuli have been clearly multidimensional. This fact is surprising since one expects the multidimensional structure to be reflected in data. It is suggested that this structure might be recovered from dispersions of comparative judgments. The suggestion is shown to be valid on three sets of paired comparison data. Implications for uni- and multidimensional scaling are discussed.
