The Conversation

Happy Sunday − and welcome to the best of The Conversation U.S. Here are a few of our recently published stories:

“A lie can travel halfway around the world while the truth is putting on its shoes.” The phrase, sometimes attributed to Mark Twain, can also be said of mis- and disinformation. But in today’s hyper-interconnected world, a more apt way to put it might be misinformation can travel around the world multiple times before the truth gets a single “like.”

One reason misinformation can spread so fast, according to Shaon Lahiri, a social and behavioral scientist within the field of public health at the College of Charleston, is what researchers call “mass psychogenic illness, a psychological condition that results in physical symptoms and spreads socially.”

Similarly, misinformation can be a conduit for social contagion.

“Social connections establish pathways of influence that can facilitate the spread of germs, mental illness and even behaviors,” he writes. “We can be profoundly influenced by others within our social networks, for better or for worse.”

In his article, one of last week’s most popular on our site, he explains how social contagions can resemble the spread of viruses, why it’s so hard to stop them, and some of the social practices you can use to inoculate yourself from contagion.
