No matter how disgusting, shocking, horrifying or abberant the person, the topic or the interview, your demeanor is ALWAYS one of neutrality. Then, don’t betray that trust – ever.
The first glimmer of judgment, shock or negative emotion the person glimpses in you – they’ll shut down. They may keep talking, but not about anything worth writing about. I laugh every time I see broadcast media do a confrontational interview. What do they get? Nada. Zip. Zero. There’s the emotional soundbite of the subject saying “No comment,” or cursing…but gee – that gets old. —Amanda Stossel, in a comment. —Interviewing: The Ignored Skill (PoynterOnline)
