For effective interview outcomes, what physical gesture should an investigator avoid?

In the context of effective interview outcomes, crossing arms defensively is a gesture that can create barriers between the investigator and the interviewee. This posture may signal discomfort, defensiveness, or a lack of openness, which can hinder the flow of communication during the interview. When an investigator crosses their arms, it can suggest that they are not fully engaged or are being judgmental, which may lead the interviewee to feel defensive or less willing to share information.

On the other hand, leaning slightly forward, making consistent eye contact, and nodding to show understanding are gestures that promote connection and encourage dialogue. Leaning forward indicates interest and attentiveness; consistent eye contact fosters trust and engagement, while nodding can validate the interviewee's points and encourage them to continue speaking. Therefore, avoiding crossing arms is crucial for ensuring an open and positive environment during interviews, which can significantly enhance the quality of the information obtained.
