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.
