We all blink our eyes frequently without even having to think about it. It helps keep our eyes lubricated and free of foreign objects. Some liars – particularly those that make a career out of it – know that blinking too often looks suspicious and sometimes they will overcompensate by maintaining eye contact with someone they are lying to and not blinking. They also use it is a way to try to control, manipulate and intimidate, but it can backfire and reveal their true intentions if you know what to look for.
