The Rise of Fake news
By James Carson
"Fake news" was not a term many people used two years ago, but it is now seen as one of the greatest threats to democracy, free debate and the Western order. […]
Governments and powerful individuals have used information as a weapon for millennia, to boost their support and quash dissidence. […] However, before the internet, it was much more expensive to distribute information, building up trust took years, and there were much simpler definitions of what constituted news and media, making regulation easier.
But the rise of social media has broken down many of the boundaries that prevented fake news from spreading in democracies, as it has allowed anyone to create and disseminate information […].
Hoaxes and falsehoods have been associated with the internet since its early days, but it is only in the last two years that organised, systematic misinformation campaigns, often linked to governments, have emerged, and their effect on democracy and society scrutinised. The 2016 US election has been seen as providing a fertile breeding ground for fake news. Some credit Donald Trump's anti-establishment rhetoric and distrust of the mainstream media. Others blame widening partisanship, which meant readers were more prone to believe and share stories that fit their beliefs.
The rise of social media itself has also been seen as central. Sites like Facebook are accused of creating "filter bubbles", the phenomenon of showing people things that they like or tend to agree with, and hiding those that they don't.
Critics of Facebook and Twitter say the sites are purpose built for spreading misinformation, with the reach of a story dependent on its ability to go viral – something that often depends on sensationalism and emotional reactions more than truth itself. […]
An aggravating effect may have been that the sheer quantity of fake news stories may have reduced trust in mainstream media – if scepticism about what people read online increases, they may not know what to think. In these situations, people tend to stick to their prejudices.
