When you go to YouTube now in Canada, a notice from the Public Health Agency of Canada pops up inviting you to Learn More from a reliable source. This strikes me a great way to encourage people to get their information from a reliable source rather than wallow in fake news online. This is particularly true of YouTube that is one of the facilitators of fake news.
More generally it shows an alternative way that social media platforms can fight fake news on key issues. They can work with governments to put appropriate information before people.
Further, the Learn More links to a government site with a wealth of information and links. Had it just been a short feel good message with a bit of advice, the site probably wouldn’t work to distract people towards reliable information. Instead the site has enough depth that one could spend a lot of time and get a satisfying picture. This is what one needs to fight fake news in a time of obsession – plenty of true news for the obsessed.
