    8 Secrets of Great Communicators  |  LinkedIn, Dr. Travis Bradberry                                                     12/20/2015
    When it comes to communication, we all tend to think we’re pretty good at it. Truth is,
    even those of us who are good communicators aren’t nearly as good as we think we are.
    This overestimation of our ability to communicate is magnified when interacting with
    people we know well.

    Researchers at the University of Chicago Booth School of Business put this theory to the
    test and what they discovered is startling. In the study, the researchers paired subjects
    with people they knew well and then again with people they’d never met. The researchers
    discovered that people who knew each other well understood each other no better than
    people who’d just met! Even worse, participants frequently overestimated their ability to
    communicate, and this was more pronounced with people they knew well.

           “Our problem in communicating with friends is that we have an illusion of insight,
            said study co-author Nicholas Epley.
Getting close to someone appears to create the illusion of understanding more
            than actual understanding.
