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".
“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.”

Zakat definitions
Zakat: an Arabic word meaning ‘to cleanse’ or ‘purification’.
Nisab: the minimum amount that a Muslim must have before being obliged to pay zakat. Traditionally, the nisab threshold was 87.48 grams of gold, or 612.36 grams of silver. The monetary value of the nisab therefore varies by current prices and currencies.
Zakat Al Mal: the ‘cleansing’ of wealth, as one of the five pillars of Islam; a spiritual duty for all Muslims meeting the ‘nisab’ wealth criteria in a lunar year, to pay 2.5 per cent of their wealth in alms to the deserving and needy.
Zakat Al Fitr: a donation to charity given during Ramadan, before Eid Al Fitr, in the form of food. Every adult Muslim who possesses food in excess of the needs of themselves and their family must pay two qadahs (an old measure just over 2 kilograms) of flour, wheat, barley or rice from each person in a household, as a minimum.
British aristocrat Lord Carnarvon, who funded the expedition to find the Tutankhamun tomb, died in a Cairo hotel four months after the crypt was opened. He had been in poor health for many years after a car crash, and a mosquito bite made worse by a shaving cut led to blood poisoning and pneumonia. Reports at the time said Lord Carnarvon suffered from “pain as the inflammation affected the nasal passages and eyes”. Decades later, scientists contended he had died of aspergillosis after inhaling spores of the fungus aspergillus in the tomb, which can lie dormant for months. The fact several others who entered were also found dead withiin a short time led to the myth of the curse.
