The top five factors were What You Say (46.3%), How You Speak and Sound (34.7%), How You Act (33.9%), What You Are Wearing (30.6%), and Your Confidence (29.3%).
What You Say (words) came first, in stark contrast with the often quoted Mehrabian Myth (shown above) that your words carry only 7% of your meaning. I blogged about it back in July 2009. (So take your speechwriting very seriously). Then came two nonverbal factors - How You Speak and Sound and How You Act. What You Are Wearing was fourth, although proponents of dressing for success would insist it instead is primary. Your Confidence only was fifth, so advocates of power posing should sit down and fold their arms.
