NBC News interviewed political scientist Brendan Nyhan about his new study on the spread of fake news.

Said Nyhan: “The group that visited fake news websites the most frequently was the 10% of Americans with the most conservative information diets. These are people who are visiting a lot of websites that are disproportionately consumed and shared by conservatives relative to liberals. It’s not that fake news is a substitute for political news, it’s being added on to a diet of like-minded political news of a more conventional variety.”

He added: “They’re a subset of Americans who follow politics extremely closely. For all the saturation coverage that politics receives, its still a pretty small part of the news diet for most people.”

Also interesting: “Facebook stands out in our data as the site people visited most disproportionately prior to visiting a fake news website. We don’t observe the same pattern with Google, Twitter, or web mail platforms. Journalists love to talk about Twitter, but it just doesn’t compare in reach to Facebook.”
