Former US president Barack Obama warned on Thursday that the way Americans communicate on social media networks has weakened democracy.
Mr Obama, who owns the podcasting and film company Higher Ground, warned that “citizens no longer know what to believe” thanks to false information spreading online.
This is leading to political scepticism among citizens, he said.
“The very design of these platforms is tilting us in the wrong direction,” Mr Obama said during a conference at Stanford University’s Cyber Policy Centre.
Hate speech, vaccine misinformation and state-sponsored amplification of fake news are feeding people’s desire to read sensational content, the former president said.
While Mr Obama acknowledged that some of the most odious content, such as racism, white supremacy and conspiracy theories, existed “long before the first tweet was sent", he said that “solving the disinformation problem” on social media networks could help to build trust and solidarity among citizens.
Although his production company is reported to be in talks with podcast distributors for a deal worth tens of millions of dollars, he said he was concerned that the way people created and marketed information through the internet posed a threat to democracy.
Mr Obama said his meetings with people at companies such as Facebook, Twitter and Google’s YouTube showed him their employees were “sincere in trying to limit content that encourages hate speech or violence".
But he said that the companies had a financial inventive to keep as many users engaged as possible.
“While content moderation can limit distribution of clearly dangerous content, it doesn’t go far enough,” Mr Obama said. “Users who want to spread disinformation have become experts in pushing right up to the line.”
He added his voice to concerns over internet-based disinformation and misinformation at a time when Elon Musk’s effort to buy Twitter has spurred debate over social media’s obligations to free speech.
