Scientists develop 'fake news' vaccine, helping inoculate people against lies

Scientists have created what they say is a vaccine against the kind of fake and hyper-partisan news that is spreading quickly across Facebook. The researchers claim that by showing people lies, they can teach them to better see the truth. The solution works in a similar way to a real vaccine – exposing people to a small amount of the problem to help them better respond to larger amounts of it. The solution could help social networks and news organisations battle against fake news, which has been credited with helping the vote for both Brexit and for Donald Trump. The study claims that if people are shown well-established facts about climate change and then lies about it, the latter will cancel out the former.
