The comments come after widespread media speculation about the impact of social media on how consumers perceive issues and society, and the potentially harmful effects of bogus news and extremist content in news feeds.
The the latest News Feed tweaks are attributed to recent user feedback, noting that people have said posts from businesses, brands and media are crowding out the "personal moments that lead us to connect more with each other".
In a blog post, Facebook CEO and Founder Mark Zuckerberg said the goal is to ensure that users feel happy when they're on the site, something that's easier to accomplish if you're seeing baby pictures rather than news articles about Russian Federation investigations.
"At its best, Facebook has always been about personal connections".
In an interview with New York Times, Zuckerberg further emphasised his desire to make social media meaningful, not just fun, and something that's "good for people". "We built Facebook to help people stay connected and bring us closer together with the people that matter to us", Zuckerberg posted on Facebook on Thursday.
The social media giant said the updates could cause traffic to fall for certain "passive" public pages that do not generate conversations between people.
Cho said her company is expanding links to other platforms, such as YouTube, that share profit with content creators.
Recently, the company partnered with fact-checkers and spent millions of dollars on combing through posts adding "disputed" tags in an effort to stop fake news from spreading on the platform.
"Academic research on correcting misinformation has shown that putting a strong image, like a red flag, next to an article may actually entrench deeply held beliefs - the opposite effect to what we intended", Facebook Product Manager Tessa Lyons said in a blog post in December.
By cutting back on items that Facebook users tend to passively consume, the change could hurt news organizations and other businesses that rely on Facebook to share their content.
By updating their algorithm to predict what a user is likely to engage with, Facebook may proliferate content that reinforces a user's existing ideologies rather than content that challenges them or makes them change their minds.
This could exacerbated the spread of fake news, as users will be less likely to see posts that originate from a different perspective.
When readers were given a contrasting view, they were able to discern what was real and what was fake.
Zuckerberg admitted that the new changes might not pay off at first, but believes it is important users have more meaningful social interactions, The Sun said.
"Now, I want to be clear: by making these changes, I expect the time people spend on Facebook and some measures of engagement will go down". But I also expect the time you do spend on Facebook will be more valuable.
