A study by the University of Toronto recently won an award. The study found that we may be able to determine narcissistic personalities by examining people's eyebrows. The study found that people with darker, bushier and more distinct eyebrows tended to be more self-centered and narcissistic. In other words, if you go on a date with someone or you're interviewing someone, they may come off very charming, but behind that charm could lurk something darker that will come out later. Look to the brows!
In my personal experiences, some of the most narcissistic people I have ever known had light and thin brows, so who knows?! But look around and see what you find!
