This study was designed to examine differences in responses to the six rational/intuitive scales of the Personal Style Inventory in relation to gender, age, ethnic group, birth country, occupation, and industry. Data were collected from 495 participants in training programs in Australia, England, New Zealand, and the United States. Multivariate analysis of variance indicated no differences among groups on the six scales which then are not sensitive to the characteristics so separate norming scores are not indicated. Lack of differences between sexes contrasts with the finding that women score more intuitive than men on other style assessment tools. Findings are not, however, consistent. And, since characteristics other than gender may show similar disparate results, further study of rational-intuitive commensurability is needed.
