Interviewer effect is a phenomenon in which the presence and behavior of an interviewer can affect the responses given by the interviewee. To describe this effect, several synonyms can be used, such as interviewer bias, interviewer context, and interviewer influence. The term interviewer bias identifies the tendency of interviewers to influence the answers of the interviewee towards their own opinions or beliefs. Interviewer context describes the impact that external factors, such as the setting or the interviewer's demeanor, can have on the interviewee's responses. Finally, interviewer influence highlights the power dynamic between the interviewer and the interviewee and how it can shape the information that is shared during the interview.
