Comment on 'Measuring Machiavellianism with Mach V: a psychometric investigation'

A recent article (Shea & Beatty, 1983) attacks the reliability, triadic-choice format, and validity of the Mach V. The issues of meaningful versus statistical criteria, differing perspectives of bias, and reliability-validity independence are raised in challenge. Although the Mach V may have some construct validity problems, Shea and Beatty's call for a new measure of Machiavellionism is not supported by their article.
