Speaking to a crowd of 12,150 at the OVO Hydro, in conversation with British journalist and author Sathnam Sanghera, the 44th president of the United States reflected on his time in the White House and examined the political and social challenges facing the US and the wider world. The event is part of three speaking dates in the UK. Obama has already appeared in Belfast and will speak in Manchester on Thursday night.
Obama said that during his 2008 presidential campaign, when social media and technology were gaining traction, he saw them as a beacon for hope. But he said the same positive forces and tools that could mobilise people around democracy or human rights could also be used by hate groups.
They “connected people for good, but also for ill,” he said.
“It turns out that the reptilian side of our brain really gets attracted to anger, fear, resentment and the sense that someone is out to get you. So a lot of social media and a lot of our information is informed around that.”
He pointed to the period after World War Two, when the US and European governments set rules because, in his words, “we've seen what propaganda can do in the hands of somebody like Hitler.”
