What happens when a group of Fox News viewers watch CNN for a month?

Watching Fox News can be like entering an alternative universe. It’s a world where Vladimir Putin isn’t actually that bad, but vaccines may be, and where some unhinged rightwing figures are celebrated as heroes, but Anthony Fauci, America’s top public health official, is an unrivaled villain.

Given the steady stream of misinformation an avid Fox News consumer is subjected to, the viewers – predominantly elderly, white and Donald Trump-supporting – are sometimes written off as lost causes by Democrats and progressives, but according to a new study, there is still hope.
