But according to Emily Falk, communication professor at the University of Pennsylvania, small talk is actually a powerful gateway to connection. When two people engage in even casual conversation — like chatting about the weather or weekend plans — their brains begin to sync up. Just like how we naturally mirror someone’s body language or tone of voice, our brains start to match up, too. The takeaway:Next time you’re tempted to skip the chitchat… don’t. A little small talk could be the first step to a deeper connection.
