Mark Zuckerberg, Founder and CEO revealed that news content will soon make up around 4% of what appeared in people's News Feeds - down from 5% before.
The move is the latest attempt by the company to quell the spread of so-called fake news and propaganda on the network.
"We could try to make that decision ourselves, but that's not something we're comfortable with," Mr Zuckerberg said.
"We considered asking outside experts, which would take the decision out of our hands but would likely not solve the objectivity problem. Or we could ask you - the community - and have your feedback determine the ranking."
Users will be asked, as they sometimes are about advertising, whether they recognise a news brand and if they trust it.
