DAVID BURKUS: One of my favorite studies, a study by Francesca Gino, asked one group of people to think about a time where they had to reach out for a professional connection and asked a second group of people when they had to reach out for a personal connection, an actual friendship. That information coming from a diverse set of people and a wide range of people becomes kind of a more valuable resource than just getting information from the same few people who look alike, think alike, act alike, work alike as you. SARAH GREEN CARMICHAEL: I think for people in a large company, one of the awkward things is if you have worked with a group of folks for a while, and you cannot remember other people’s names.
