"Intentionally maintaining direct eye contact led to less persuasion than did gazing at the mouth"
How many management communications training tell us ' to make strong eye contact' to be more convicing?
Recent research at the University of British Columbia looked at eye contact patterns and persuasion. It concluded that we are more easily persuaded with a little less eye contact, especially when 'additional' eye contact is 'deployed'.
So if you're out at a meeting and need to be a bit persuasive, split looking at the persons mouth and eyes!
