Reveal Your Flaws From Time to Time. Nobody’s perfect, and you’re not expected to be. We’re all human. There’s something called the “Pratfall Effect” where people will like you more after you make a mistake, but only if they believe that you’re competent to begin with. This makes you relatable and vulnerable to the people around you. There was a study done at the University of Texas, Austin where they studied how mistakes can affect attraction. They listened to people taking a quiz, and found that people who did well on the quiz, but spilled coffee at the end of the interview were rated higher than people who did well on the quiz and didn’t spill coffee, or people who failed the quiz and spilled coffee.
