This research, in turn, could lead to effective strategies to counter that bias by diversifying social networks.
“There’s a fundamental question about how people perceive their environment in an unequal society,” said co-author Eun Lee, a network scientist based at the University of North Carolina. Her interest in the topic was piqued in the wake of the 2016 US election and the mass protests and subsequent impeachment of the president in her native South Korea that same year. “Both sides had been separated into two groups by each issue”, Lee wrote in an accompanying Nature essay. “At the time, I was studying topics related to opinion dynamics models and wondered what was leading these collective segregation behaviours.
