Gossiping Is Smarter Than You Think

Before there was social media, there was gossip. Long before tweets could topple reputations, whispers did the job just fine—sometimes with deadlier precision. Gossip fed the frenzy of the Salem Witch Trials and has been the subtext of one too many fables where mischief masks moral rot. But gossip has also been a lifeline, fueling resistance, stitching together communities, and rallying support for social justice movements the world over.  Historically, gossip is equal parts social glue and poison. And it also has a far more pedestrian side—as the fodder of our mundane daily conversations. By some accounts, more than 65% of our conversations are about other people. The stories we tell about others helps to spice up the doldrums of life. This explains why Page Six draws 21 million monthly readers or why an entire teenage generation (myself included) nourished themselves on the dramatic woes of Gossip Girl.  The fact that we all gossip so much—without getting caught—is a paradox hiding in plain sight: how do we so freely spread sensitive information, often about people we know, without the subject of our gossip ever finding out? In a paper recently published in Nature Human Behaviour we discovered the answer to this question.  Let’s first consider the scope of the problem. If you want to predict where information will spread, you need to estimate how it might move through your social network—not just among your friends, but your friends’ friends, and so on. Social networks typically include hundreds of people, with tens of thousands of possible connections. To predict where a piece of gossip might travel, you need to calculate which of many paths it might travel along. That is a staggering amount of mental math. And yet, humans appear to do this effortlessly before letting gossip slip.  Intrigued by this puzzle, my team of researchers at Brown University, led by graduate student Alice Xia, ran a set of studies to understand how humans pull off this impressive feat. We started by designing a series of lab experiments using small, artificial social networks. Participants watched pairs of people interact—each interaction representing a friendship—and pieced together a mental map of the network, similar to how we link different streets together to map out an entire neighborhood. As people gathered information about who was friends with whom, they began to infer who was well-connected, who was further removed, and who was well-liked and popular. Then we asked participants to share information with others without letting it reach the target of this gossip. What we found was striking. People tracked two key features of the network that aren’t directly visible. First, they noted how far the target was from their conversation partner. Second, they paid attention to how popular their conversation partner was. Participants gossiped the least with people who were close to the target—especially if they were popular—and gossiped the most with those who were both popular and socially distant from the target. In other words, people intuitively used popularity and distance to calculate where gossip might spread.  Our research reflects how gossip operates in relatively small networks. What happens in the real-world where there are hundreds of people in a network? Out in the wild, it’s nearly impossible to know all the relationships around you, and tracking how gossip might travel becomes a serious cognitive challenge. In Brown University’s freshman class, we recorded who was friends with whom, and then asked students to guess which peers might hear a piece of gossip depending on where it originated. Even in these large, real-world networks, students formed mental maps that captured the two key features: how popular someone was and how far they were from the target of gossip. These mental maps helped them estimate where gossip was likely to spread. It might seem like a lot of effort to keep gossip from getting into the wrong hands, but the cost of getting it wrong is steep. I recently finished Edith Wharton’s novel House of Mirth, where reputation is currency and gossip is the unsung villain, enforcing the rigid rules of New York high society while destroying its nonconforming heroine, Lily Bart. Lily is a cautionary tale for how a life can be undone by backroom rumors if you don’t stay ahead of the gossip game. The ability to gossip effectively and with such precision is a testament to the mind’s sophistication—a feature, not a bug. Gossip, for all its bad press, is not a character flaw. Rather, it’s a powerful cognitive tool that allows our minds to weigh social risk like a chess master, many moves ahead. We therefore need to stop treating gossip as a moral failing and start recognizing it as a form of social intelligence, a vital skill for managing relationships, reputations, and the flow of information in our modern world. Gossiping wisely is not just smarter than we think—it’s essential for social survival.
