• Facebook chief to change news feed to combat 'sensationalism'
• 'There's too much misinformation and polarization in the world'

Facebook will begin to prioritize "trustworthy" news outlets on its stream of social media posts as it works to combat "sensationalism" and "misinformation", its chief executive, Mark Zuckerberg, said on Friday.

The company, which has more than 2 billion monthly users, said it would use surveys to determine rankings on how trustworthy news outlets are.
