But there’s more. At work, if you are unlikable, people start thinking you are less competent. So stop thinking you can skate by on your genius IQ because you can’t. You need emotional intelligence as well. This situation is so pronounced that there are special-education classrooms rife with kids who could read when they were three. Social skills matter as much as intelligence when it comes to long-term success, even for the geniuses.
