Whether you believe him or not, Zuckerberg says that 99 percent of the news on Facebook is legitimate. It's hard to believe, given that Facebook came under fire following the election for allowing the rampant spread of fake news. We all saw it, illegitimate news being shared from both sides of the party, some of it clearly fake, others, not so much.

Zuckerberg's figure comes from a lengthy blog post that addresses the election and the role Facebook played in influencing voters.

"After the election, many people are asking whether fake news contributed to the result, and what our responsibility is to prevent fake news from spreading," Zuckerberg said. "These are very important questions and I care deeply about getting them right. I want to do my best to explain what we know here. Of all the content on Facebook, more than 99% of what people see is authentic. Only a very small amount is fake news and hoaxes. The hoaxes that do exist are not limited to one partisan view, or even to politics. Overall, this makes it extremely unlikely hoaxes changed the outcome of this election in one direction or the other."

That's true, there are all sorts of hoaxes on Facebook, but there's a big difference between someone posting about Bigfoot and someone else posting about a fake news story about a candidate. And it wasn't limited to just posts about Donald Trump or Hillary Clinton, both were affected during the past several months. Obviously, this is important as it might skew the minds of voters, even if the story isn't true.

Finding the truth is complicated, Zuckerberg admits

Zuckerberg said that Facebook also played an important role in the election, encouraging more than 2 million people to vote. He promises changes but admitted that identifying the "truth" is complicated. Sort of makes you wonder how he came up with his figure that just 1 percent of the news is fake, doesn't it?
