Guttman scalogram analysis, the basis for much research on the United States Supreme Court, has not yet been extensively applied to state courts. Hypothesizing that the attitude variables currently used for the Supreme Court analyses are inappropriate to the sorts of cases that state courts handle, Professor Fair made an experimental application of scalogram analysis to the Pennsylvania Supreme Court. He found that, by modifying one of the variables currently used, it is possible to account for a large percentage of cases with a relatively few number of scales. He concludes that scalogram analysis can be as successfully used in the study of state supreme courts as it has been in the study of the United States Supreme Court.
