The present paper investigates how the distinction of different facets
of anti-Semitism is to be understood from a methodological point of
view. Does it mean that there is a unique (quantitative) dimension of
anti-Semitism on which the participants can be ordered due to a variety
of expressions of anti-Semitic prejudice, or does it imply that these
facets are independent dimensions of anti-Semitism, which combine themselves
into (qualitatively) different syndromes of anti-Semitism?
After discussing various methodological approaches to the analysis of
homogeneity vs. inhomogeneity of tests or questionnaires, the paper
applies these methodologies to data from an anti-Semitism survey by
Petzold (2004) and comes to the conclusion that the facets are no independent
constructs. All of them are indicators of one and the same anti-Semitic
attitude whose expression is partly modified during the strengthening
of anti-Semitic prejudice, however.
