You really can't spend any time online these days without realizing that a lot of the news that we read isn't actually news at all. It's either faked, maliciously wrong or otherwise just not quite right. This 'news' then gets repeated, copied, shared on social media and before you know it, people take it as gospel. Google News is trying to do something about that, which is to roll out a 'fact check' option. There are a number of sites online that do their best to check the authority and validity of what is said online, and Google is now starting to link to these when displaying news stories. It's not particularly well signposted however, so you might need to search for it a little bit. Google's blog post goes into a bit more detail on it.
This is a screen shot of what Google is using to advertise this:
You'll see just above the images 'Fact Check' and if you click on that link you'll get taken to the Full Fact website, where you can check for yourself. This is rolling out in the US and UK first of all, and then the rest of the world afterwards. However, I'm not yet seeing it myself, even when I search on Google.com, so I guess it's a slow roll out. Worth keeping an eye on it though!
