For the first group, the actor was dressed as a private; for the second, as a sergeant; for the third, as a captain, and, finally, for the fourth grup, as a Colonel. The inductees were asked to fill out a questionnaire evaluating the speech. Among the questions was one asking for an estimate of the lecturer’s height.
