Introductory textbooks socialize students by exposing them to core subfields within the discipline. The purpose of this paper is to understand the nature and extent of research methods and ethics coverage in introductory criminal justice and criminology textbooks. Analysis of 15 introductory criminal justice and 10 criminology textbooks suggests that while criminology textbooks do a better job of introducing students to research methods and ethics, the discussions are rather sparse and cursory. Of primary importance in this discussion is how neglecting research methods and research ethics in introductory textbooks may impact the disciplines of criminal justice and criminology.
