It's the network, stupid: study offers fresh insight into why we're so divided
Social perception bias is best defined as the all-too-human tendency to assume that everyone else holds the same opinions and values as we do. That bias might, for instance, lead us to over- or under-estimate the size and influence of an opposing group. It tends to be especially pronounced when it comes to contentious polarizing issues like race, gun control, abortion, or national elections. Researchers have long attributed this and other well-known cognitive biases to innate flaws in individual human thought processes.
