But Epley’s research indicated that such methods, particularly when forced, undermine real communication. Nodding doesn’t mean you’re listening. Constant smiling and eye contact can be a little…intense. Besides, Epley believed, everyone already knows how to listen closely. “You don’t need anyone to teach you how to listen to an interesting podcast or a good joke,” he told me. “When you’re in a great conversation, no one has a problem following along. When something is interesting, you listen without thinking about it.”
