Dr. Alucard conducted a study to examine various aspects of the sexual behaviors of college students. The students filled out a questionnaire in a classroom on the campus; about 50 students were tested at a time. The questionnaire asked about prior experience with various sexual practices. If a student had experience, a number of other detailed questions were asked. However, if the student did not have any prior experience, he or she skipped the detailed questions and simply went on to answer another general question about a sexual experience. What ethical issues arise when conducting research such as this? Do you detect any specific problems that might arise because of the "skip" procedure used in this study?
