This chapter outlines some of the existing research-based strategies and tactics developed to gather information from semi-cooperative subjects. The chapter suggests that a subject’s resistance postures are different from their counter-interview strategies. It further suggests that the resistance dimension translates to the quality of the relationship between the interacting parts (e.g., the willingness to communicate with the interviewer), whereas the counter-interview dimension translates to the precision of the information being revealed (i.e., the accuracy and precision of the gathered information). The chapter proposes that the interviewer can be more successful with establishing a functional working relationship by applying social influence strategies and that interviewers can be more successful with gathering specific pieces of information by applying cognitive influence strategies. The chapter then categorizes the research-based interview techniques based on what type of behavior they primarily aim to affect. The chapter concludes with outlining some positive findings from having trained interviewers to adopt science-based strategies.
