If possible, give the reporter literature from your opponents. This sends the message that you know both sides of the issue and are confident in your position. Monitor body language. Holding your hands open at your side or on your chest suggests openness and honesty. Hidden or clenched hands infer anger, hostility and non-cooperation.
Straight posture implies self-confidence and self control.
Direct eye contact conveys openness and honesty. Frequent eye blinking and lack of eye contact convey deceitfulness and inattentiveness. A raised voice conveys nervousness. Coat off, sleeves rolled up, and so forth infer openness, competence and expertise. When possible, eliminate all barriers such as desks and tables.
